Hand rammer dimensions. Vibratory plates and vibrorammers (rammers)

Construction companies that regularly ram and compact soil, asphalt or gravel, as well as professionally lay paving slabs, will find vibrating plates and rammers on our website at low prices recommended by the direct manufacturer of this equipment. As an official dealer of this product, we constantly surprise our customers with high-quality technical products that facilitate the work of construction specialists. We'll show you how to choose the right one tamping machine for a specific purpose.

First, decide on the weight of the unit (it can vary from 54 to 321 kg). For example, works on landscape improvement, laying of small-ground paths, laying of paving slabs and polyurethane mats require small models of vibrating plates with a weight not exceeding 75-90 kg.

Repair of pits in the road surface, grinding of asphalt after engineering communication and laying works, manipulation of the soil, the thickness of which is about 25 cm, involves the use of rammers with a weight of up to 90 - 140 kg.

Compaction of trenches, compaction of erected roads and interaction with sufficiently thick soil requires a vibrating plate with a heavy mass. In this case you will need buy a vibrorammer from 140 kg and above.

Vibratory plate price largely depends on the type of its engine. Our vibrotechnics have petrol and diesel engines, which equally well cope with the tasks assigned to them. The type of the motor mechanism does not affect the productivity of the vibrating plate, but has its own characteristics in its operation. For example, gasoline exhaust plate has a low cost, impressive power and low noise level during operation. Such a unit is able to function in any conditions, since it does not need power supply. The diesel version of the vibrating plate is less popular, since it costs much more and has a high noise threshold, however, it allows its owner to save a lot on fuel consumption. An important criterion for choosing this equipment is the size of its working platform. It ranges from 430x310 mm to 890x670 mm. When evaluating the vibrating plate model, do not forget about its additional options. The presence of an irrigation system, a folding handle and transport wheels will greatly facilitate your work.

Masalta is a Chinese manufacturer of a wide range of equipment and components for the construction industry. Our main products include concrete compaction equipment, vibrating screeds, trowels, floor saws, concrete mixers and light towers. Masalta has gone through a period of rapid growth and expansion in recent years. In 1996, our company began to produce cutters for milling machines. In 1999, we started the production of plate compactors, and in 2005, the first vibrating rammers rolled off our assembly line. In 2008, our single and double drum vibratory rollers entered the world market.

Our company presents a wide range of products under the Masalta brand, which are specially designed to meet the growing demands of the market. We offer ergonomic machines that are characterized by high stability and productivity.

Tamping is required when building on the ground, backfilling a pillow under the foundation (on any soil), arranging a sand layer for the floor, laying paving slabs. It is performed either manually (using a home-made or factory-made tool), or mechanized, using various vibration devices. When working with equipment that operates by transmitting strong mechanical vibrations, it is mandatory to use protective equipment for hearing and vision organs, as well as special gloves, shoes and clothing.

The goal is to obtain a dense layer that is not subject to heaving, shrinkage, compression, to create a reliable support for the foundation, floor, and road surface. According to the technology, several passes are usually made over the entire surface, then the quality of the seal is visually assessed. Well-compacted material does not fall through when stepped on.

Where is sand compaction needed?

1. Sandy soil.

The main distinguishing feature is that it does not retain water well. Therefore, this type of soil is not subject to frost heaving, which means it is suitable for buildings, including residential ones, but only one-story or very light ones. Heaving soils in winter begin to push out the foundation. This is because the water they contain freezes and expands. Such soils, unlike sandy ones, are little or completely unsuitable for construction. They, as well as weak soils, are often completely removed and replaced with sand. In any case, in preparation for the installation of the foundation, careful tamping by hand or with the use of special tools is required.

In the process, the site is passed three times. If after the third time it was not possible to achieve the desired result, then the layer is made thinner. When compacting sand, including when preparing the soil, it is necessary to wet it, but moderately. Dry bulk material does not hold together, and too wet material cannot be compacted with high quality. It is easy to check the degree of moisture - if, when squeezed in the hand, it does not stick together into a lump and does not crumble, then you can get to work. In the hot season, you will have to constantly wet the surface, as it dries quickly.

2. Sandy foundation pad.

Foundation bedding is used in the construction of light structures: frame, foam block or one-story from heavier materials. It is not suitable for mounting the foundations of multi-storey buildings, since it does not have a high bearing capacity.

Coarse river or washed quarry sand is suitable for building a foundation cushion. Buying a cheaper (unwashed) is not worth it. The difference in price is insignificant, but at the same time, the dirty one has a high content of impurities, primarily clay, which adversely affects the strength of the foundation of the structure.

Positive characteristics of the foundation pillow:

ease of manufacture - ordinary backfill, without the use of complex equipment;
availability - sand is easy to buy with delivery in any region;
low price;
well reduces the load on the soil;
easy sealing even by hand.

Not recommended for soils with high water levels. If this material is the only possible option, then geotextiles are laid on the bottom of the trench or pit. The thickness of the reservoir is selected taking into account the expected load, type of soil. Sand is poured in layers, moistened (but not filled with water) and compacted tightly.

3. Underlayment for the floor.

When arranging in houses on the ground, a non-rigid underlying layer is necessarily arranged. It includes two layers. They are poured over gravel or rubble, each layer is moistened and rammed. For backfilling, as well as under the foundation, river sand or washed quarry sand is used. To achieve uniformity of thickness, pegs are installed, after which they are removed.

4. Laying paving slabs.

When paving pedestrian roads, alleys and platforms with paving slabs, sand is also necessarily used. The first and final layers of the pillow under the paving stones are made from it. Between them, crushed stone is used as a layer. According to the requirements of technology, all layers of the cake under the tile are tightly tamped, and periodically moistened to achieve the best result.

For backfilling, sifted river material is taken. The thickness of its layers is determined depending on the depth of the trench, the height of the pavement element. Often it is necessary to remove the soil to a great depth due to heaving, other problems that do not allow the soil to become a reliable basis for the installation of paving slabs. In these cases, it is necessary to add a lot of sand and carefully compact it. The final layer is made about 7 cm, dry cement is often added to it.

Rammer accessories

1. Manual.

Made of metal, it weighs from 5 to 10 kg. It consists of a handle and a base ("paw") - a plate about 20 x 25 cm in size or a channel (the smaller the dimensions of this part of the device, the greater the impact force). The handle of the tool is straight (in the form of a pipe) or T-shaped, with two handles on the sides. If necessary, a manual rammer with a channel can be weighted by pouring cement.

If there is a need to save money, then it is easy to make the device yourself. Two manufacturing options:

Make a handle from a heavy wooden beam about 1 m long and nail a “paw” from a solid board to it from below.
Buy a separately finished plate (costs about 1000 rubles) and plant it on a shovel handle or a metal stick.

2. Vibrotamper.

For compaction of soil and bulk materials, including sand, in a limited space, a “vibronog” is used. The engine of this device runs on gasoline or diesel fuel. At the base of the device there is a “heel” plate with a width of 15 to 30 cm and a length of about 33 cm. Vibratory rammers also differ in power. The principle of operation is based on a vertically directed force, like a manual device, but the efficiency is much greater. This type of equipment is used on sites where it is impossible to operate large-sized equipment: vibratory plates and vibratory rollers.

2.1. Vibrating plate.

For work on a large area, subject to the possibility of free movement, a rammer using a vibrating plate is suitable. This apparatus consists of an engine, a basket with a central shaft, a "heel" or "shoe" and a guide handle. The unit moves back and forth, transmitting a strong mechanical vibration (vibration) to the sand particles, due to which compaction occurs.

Types of equipment for soil and bulk materials with a slab base:

gasoline;
diesel;
hydraulic;
electrical;
with remote control.

Vibrating plates vary in weight. The lightest ones are suitable for sand.

2.2. Vibratory roller.

For the largest volumes of work, vibratory rollers are used. Their types:

with manual control due to the guide handle;
self-propelled with a cabin for the operator single-drum (rear on wheels);
with cab 2-roller;
trench with remote control.

The device of a high-quality vibratory roller allows compaction also along the edges of the site, that is, the use of additional equipment (manual or vibrorammers) is not required.

Price

The price of the services of professional builders for compacting sandy soil or sand bedding is from 90 to 600 rubles per m2. If the area to be compacted is large, or if we are talking about permanent work, then you need to compare these prices with the cost of the equipment. In many cases, it is advisable to purchase a fixture or rent it and do it yourself.

Renting a device for compaction by hand costs about 500 rubles per week, rental of a vibrating plate or vibrating rammer (depending on the model) - from 700 to 3000 per day.

Depending on the type of equipment, either a vertically directed impact force or vibration transmitted from the roller shaft or the plate base acts. In any case, the technology does not include any secrets and complexities.

When building foundations for houses, garages, country paths and much more, great attention is paid to the substrate, consisting of gravel and sand. In order for the concrete monolith to be laid evenly and not begin to move over time, it is important to carefully level the underlying layer. For these purposes, you can use specialized vibro-rammers or rolling equipment, but manual rammers will be much cheaper.

The principle of do-it-yourself processing is that with the help of a home-made tool, blows are applied to the surface, due to which sand and gravel are compacted. In this case, tamping is performed after laying each of these layers.

Features of crushed stone compaction

Any novice builder sincerely wonders why ram an already strong stone. However, there are a few important things to keep in mind:

Since crushed stone is obtained by crushing, its particles are obtained in different sizes with free-form faces. Because of this, when laying the underlying layer, the particles of the material do not completely adjoin each other, forming a large number of air voids, the appearance of which, ultimately, leads to a decrease in the level of load resistance. If the crushed stone fragments fit snugly together, the volume of the material will be reduced, but a stronger base will be formed.
If crushed stone is laid on rocky soil, then tamping can be dispensed with. In this case, it is only necessary to level the gravel.
After compacting the gravel, the thickness of the layer can be from 50 to 250 mm, depending on the loads that will be applied to the base.

In addition, when processing crushed stone, it is recommended to perform a base buckling. To do this, you need to divide the gravel into fractions. First, the larger material is laid, which is compacted by hand. Then the smaller material is backfilled, which is also compacted. The final top layer should consist of the finest material itself, which must be carefully leveled and recompacted.

Thanks to this, the finished base will be distinguished by increased strength. If you make a similar manual tamping of sand, the effect will be even better.

Features of sand compaction

Do-it-yourself sand tamping is distinguished by some nuances that should be considered when creating a solid foundation for a concrete slab.

First of all, it is worth deciding on the type of sand that is best suited for these purposes. It is better to use gravelly material, but it is not recommended to fill in fine-grained sand for tamping. The larger the grains, the greater the compressive strength of the base will be, so that shrinkage of the future house or parking lot can be avoided.

If you are planning to build a monolithic structure, then it is best to give preference to river or quarry sand of medium fraction. However, even in this case, the underlying layer will be affected by groundwater. Therefore, in order to prevent the process of erosion of the base, it is necessary to lay geotextiles on the bottom of the trench, and only then fill in the sand.

In addition, before filling sand, it must be sieved, since the presence of impurities (especially clay) can affect its properties. Watch the moisture level of the material, the ideal consistency will be if you can roll a small ball out of the sand, which will not crumble immediately. Accordingly, the moisture content of the sand should be in the range of 8-14%.

Accordingly, 50% of the successful laying of a gravel-sand cushion depends on the material itself, the remaining 50% falls on the equipment. As mentioned earlier, specialized machines can be used for these purposes, but it is much cheaper to make a manual rammer yourself.

Making a manual rammer

There are many options for making a do-it-yourself rammer. Someone makes massive structures made entirely of iron, but in this case, welding will be required. Others prefer to get by with improvised materials. Consider the best option for manufacturing a manual rammer for compacting soil, sand and gravel.

This will require a standard square beam of 100 - 150 mm. It should not be rotten or exfoliated.

Healthy! Some use round logs, but with the help of such rammers it is impossible to fully compact the base in the corners.

You will also need to prepare:

Steel plate with a thickness of at least 2 mm.
A round stick about 450 mm long (it will act as a handle for the future rammer). To do this, you can use an unnecessary stalk from a shovel.
Screws and wood glue.

We make blanks

We will prepare the design according to the drawing shown below.

After preparing everything you need, saw off the ends of the timber at a right even angle, according to the dimensions. After that, it is necessary to level the plane of the lower end of the bar with a planer and remove chamfers of about 5 mm in size from the edges of the workpiece.

In order not to get numerous splinters during the work, it is recommended to sand and grind the surface of the bar.

We make a "shoe"

The next step in creating a do-it-yourself tamping tool is the manufacture of a metal "shoe" from a sheet of steel. To cut the plate, use the following template.

Or, you can simply install the beam with the lower end on a sheet of metal and circle it with a pencil.

After that you need:

Cut the workpiece, as in the picture, using special metal scissors or using a grinder.
Remove metal burrs from the "shoe". To do this, it is most convenient to clamp the workpiece in a vice and remove the excess with a file.
Without removing the “shoe” from the vise, drill holes for the screws at the previously marked points.
Clean the surface with sandpaper.
Bend the "wings" of the workpiece and install the beam in the "shoe". If the workpiece turned out to be a little wider, it is necessary to knock out the “wings” with a hammer.
Place the drill bit in the screw holes and drill through the wood at a slight angle.
Fix the screws on all sides.

Installing the handle

Stepping back 100 mm from the top edge of the bar, it is necessary to outline the center of the future handle. To do this, you must first measure the diameter of the handle from the shovel. Let's say it is 36 mm. In order for the handle not to dangle, you need to use a drill, the diameter of which will be several mm smaller than the diameter of the handle. In this case, it should be borne in mind that the outer part of the hole in the bar will be slightly larger than the inner diameter, therefore, in the process of work, it is necessary to periodically insert the handle into the bar and check how tightly it sits.

If the handle does not fit into the hole, in no case should you try to hammer it with a hammer. Otherwise, the timber may crack and the manufacture of a rammer for earth, sand and gravel with your own hands will have to be started anew. It is much easier to slightly plan the cutting to the required diameter.

After the hole is ready, it is necessary to apply glue to its walls and install the handle. Excess adhesive can be removed with a cloth. In order for the handle to hold tightly, you need to fix it with a long screw, which must be screwed in from one side of the beam.

When the glue gains strength, you can start using the tamper. It is best to store a homemade tool in a dry place, or you can pre-paint the workpiece so that it lasts longer. If necessary, the steel nozzle can be easily replaced with a new one.

In custody

Using a hand tool, you can compact sand, gravel or soil. However, it should be borne in mind that in this case, human muscle strength is used, so it will be expensive to use such a tool to compact large areas. Such rammers are recommended for use when building a foundation for small buildings or when arranging garden areas.

Loose road surfaces. For example, for tamping sand, gravel, sand-gravel mixture, asphalt concrete for repair, road construction and other works that are associated with surface compaction in confined spaces.
Very often, such equipment can facilitate the compaction of a sand cushion for the foundation.

Sand compaction process

In fact, a vibrating plate is a steel or cast iron plate equipped with an engine. The surface is compacted under the influence of the vertical component of the centrifugal force that occurs in the electromechanical vibrator.

To date, this is the most optimal, mobile and affordable road construction equipment for tamping. They are used where the presence of heavy equipment is impractical.

Main characteristics and varieties

The main characteristics are:

weight;
performance;
compaction depth;
base area;
vibration force;
engine power.

Mass characteristic

with a mass of 70-200 kg, they are used for strengthening and sealing work on roadsides, for patching the road. A tool weighing up to 100 kg is also used at small construction sites.
with a mass of more than 200 kg, they are used for soil compaction at pipes, for bridge abutments, for backfilling trenches.

By performance

Depending on what area can be processed per unit of time, vibrating plates can have a capacity of 100-920 m2/hour.

By compaction depth

The compaction depth depends on the power and weight of the vibrating plate:

compaction depth 15 cm - for compaction of sand or gravel, while the mass of the vibrating plate does not exceed 80 kg;
compaction depth of about 25 cm - for landscape work, the mass of the plate is about 95 kg.

By base area

The base area is entirely dependent on engine power. The compaction depth is greater at maximum vibration force, which is a consequence of the high power and small footprint.

Vibrating plates by engine type

The following types of equipment are produced:

electrical;
gasoline;
diesel.

Electric vibrating plates: advantages, disadvantages

Typically, electric vibrating plates are used for compacting soil and sand. They have low weight and power, work at a depth of up to 3 m.

The area of use of an electric vibrating plate is limited by the cable length and mains voltage (42, 220 or 380 V), weight 40-80 kg.

The advantages include:

low noise level during operation;
ease of operation;
maneuverability;
durability;
it can be used indoors, as it does not emit harmful gases.

The electric vibrating plate has only one tangible drawback: you definitely need an electric cable, which you have to constantly monitor, protecting it from damage.

Prices for electric vibrating plates depend on the characteristics of the device. For example, a vibrating plate SO-325 with a compaction depth of 100 mm costs about 30,280 rubles, and SO-218M with a compaction depth of 225 mm costs more - about 43,730 rubles.

Mobile models on gasoline - conveniently and autonomously

They work from a gasoline engine with a capacity of 4 to 13 horsepower, which is refueled with gasoline of a brand not lower than A95 (or oil). Fuel consumption from 0.8-1 l of gasoline and above. Heavy plates weighing 300-500 kg are equipped with air- or liquid-cooled engines.

Advantages:

the petrol vibrating plate is autonomous and mobile, it can work wherever there is oil and petrol;
functionality is practically independent of cold, heat or precipitation.

Disadvantage: cannot be used indoors, as it emits harmful exhaust gases.

The cost of a gasoline vibrating plate depends on the characteristics of the device. For example, GROST VH 50 with a weight of 54 kg and an engine power of 2.5 l / s costs 27,550 rubles, and a SPLITSTONE VS-246E12 with a weight of 140 kg and an engine power of 6 l / s costs more - 62,660 rubles.

More efficient diesel models

The diesel vibrating plate is equipped with a single-cylinder engine, usually air-cooled. Maximum weight - 1000 kg, the most powerful diesel models can replace a skating rink weighing 7 tons.

Advantages:

wear resistance;
maintains the maximum and long loadings;
high performance;
low fuel consumption (from 0.4 l / h and above, depending on the power).

Disadvantage: Cannot be used in closed spaces, although the number of harmful emissions is less compared to gasoline stoves.

Since fuel consumption is less than that of gasoline, the price is much higher. For example, a diesel vibrating plate TSS-MS120-K costs 52,470 rubles, and a reversible diesel vibrating plate TSS-MS330-KE costs 127,160 rubles.

What if you rent equipment?

If we take into account the cost of vibrating plates, then sometimes during construction it is more profitable not to buy expensive equipment, but to rent it. This will reduce construction costs.

Of course, this is beneficial only in the case of one-time work, so as not to spend money on storage and repair of the vibrating plate. But more and more often, even construction companies prefer to rent a vibrating plate. This service is in demand due to affordable prices.

You can rent for a period of one day to several months. The entire rental period is provided by a serious landlord with technical support.

The rental price will depend on what dimensions the selected model has, what weight, the size of the slab and the impact force, whether the work will take place indoors or outdoors. You will need to leave a deposit as soon as possible.

So, a petrol vibrating plate (compaction depth 150 mm) worth 35,000 rubles is rented out for a day at a price of 900 rubles with a deposit of 9,000 rubles. If you take for a longer period, it will be a little cheaper. For example, rent for 20 days will cost 700 rubles per day.

Of course, the rental price will differ depending on which model you have chosen. There are firms that rent equipment on several other terms (without collateral or with their own specialist).

When compacting sand in confined spaces, where heavy equipment cannot be used, vibrating plates with different types of engines are simply irreplaceable.

Soil compaction: conclusion and summing up

A vibrating plate is a fairly useful type of equipment for construction. Of course, for a one-time tamping of soil under a canopy in the country, it makes no sense to buy such a tool. If there is a construction, then the vibrating plate is simply irreplaceable. The compaction of the soil with a vibrating plate is due to the impact force that is formed in the engine, is transmitted to the paw (working surface) and rams the soil very high quality.

Sealing features

Basically, the plates differ in the weight of the unit, the sealing force of the vibration, the area of the working foot and the motors. The quality of work on different surfaces depends on the weight of the vibrating plate. For example, a light one will not go over large gravel, and a heavy one will break paving slabs.

By weight, vibrating plates are light, universal, medium-heavy and heavy. The first weigh about 75 kg. They are suitable for pavement, thin layers of sand. Usually used in agriculture and cottages, as well as for landscape design, when arranging paths, flower beds. Universal have a weight of up to 200 kg. They take thin layers of soil and asphalt.

Medium weights weigh about 400 kg. Such devices take rather large layers, gravel, rocks. But heavy units are already small rollers. Weight (more than half a ton) allows you to achieve incredible success in laying freeways.

Another difference between vibrating plates is the type of engine. It can be powered by the mains, be gasoline or diesel. Each has its own disadvantages and advantages.

Vibratory plate control can be manual and remote. Manual speed is usually low. It should be remembered for the safety of the person leading the stove: you must always be behind when working.

The electric type of rammer is best suited for simple and light chores. First, it requires an energy source that will be difficult to carry around. Secondly, it is usually small and used on thin layers or soft ground.

Remoteness from the source of energy makes the gasoline unit very convenient and virtually universal. Its cost is slightly more than the price of an electric one. Thanks to the weight and power of the gasoline-powered engine, work is done twice as fast.

Diesel is cheaper than gasoline, so a diesel vibrorammer has its advantages. Its engine has more potential for work due to the durability of the service. In addition, they are quite reliable.

Reverse vibrating plates have a good feature: they can turn and get where no other device will go. However, machines with translational direction and one unbalance last longer.

The vibrating plate consists of an engine, electric, internal combustion or diesel, an eccentric unbalance - a device that gives vibration and paws of the working surface tamping the ground.

Back to index

Soil compaction scheme when backfilling trenches: 1 - area above the pipeline where soil compaction is prohibited, 2, 3 - thickness of the soil layer compacted by manual mechanisms, 4.5 - soil layer.

When choosing a plate, it is necessary to take into account the characteristics indicated in the documentation supplied with the unit. The smaller the base plate, the greater the vibration force. And it must be borne in mind that if there is a wide plate on a powerful unit, then the equipment will fly quickly, because the generated force will be very large. And if you put a smaller work surface, you get a powerful and durable unit.

The quality of the result depends on the frequency of vibration. The depth of execution, when the soil is compacted, is the thickness of the layer that the vibrating plate is able to compact. Vibration amplitude is the force of impact on the surface. The higher the amplitude, the stronger the aggregate. Naturally, its efficiency and payback depend on the consumption of fuel or energy. Documents often state performance. These figures are approximate for the purchased unit. It is possible that he will far exceed these figures.

Those devices that are able to ram asphalt and do high-quality soil compaction most often come with an irrigation system. It does not allow viscous asphalt to stick to the paw of the vibrating plate. You need to remember about the work surface. If it is embossed and heavy, it is preferable to work on the ground. If the weight is small, the paw surface is smooth and the vibration amplitude is low, then asphalt is needed.

When compacting the soil (crushed stone), all debris must be removed from the site. Sand, gravel and small gravel are left. Clay also needs to be removed by about half a meter. Compacted sand and crushed stone hold heavy loads well. Therefore, it is an ideal cushion under the foundation, under the floor in warehouses and other large structures.

The site is passed three times. If the desired result was not achieved during these passes, then the layer needs to be reduced. The total thickness of the compacted surface, sand and gravel is no more than half a meter. After the desired compaction of the soil is achieved, a new layer is laid and again passed by a vibrotamper. You also need to consider: sand and any soil should be slightly moistened.

A large amount of water will lead to poor-quality ramming, as liquid will accumulate in the voids. And dry material will not hold together. In this case, water is used as a cementing agent. The main thing is to know the measure.

In order to compact the soil under the slab and the paving slab itself, a damping plate is put on the working surface of the vibrating plate. For such work, you need a weak, lightweight unit, possibly an electric one. In the power source of such a plate, a voltage of 220 - 380 V is sufficient, depending on the engine power. The weight of the vibrating plate in this case is 50-100 kg.

Features of device care

Soil compaction with a vibrorammer is very convenient in cramped places: near foundations, pipes, wells, trenches. In general, it is usually used where the ice rink will not pass. If high-quality soil compaction is not done during construction, after a certain time, its subsidence may begin.

Before the construction of the roadbed, tamping of the earth is needed. From above it is necessary to make a pillow before asphalting. If the compaction of the soil is made uneven or poorly executed, then during self-shrinkage, pits and voids will appear inside the web. This is quite dangerous for pedestrians and motorists.

It is also convenient when laying the foundation.

Before pouring concrete, a sand cushion is always required.

The bottom of the ditch is carefully rammed. It is desirable that the nozzle on the rammer is already at the bottom of the ditch, that is, in size. After compaction of the soil, a thin layer of sand is poured, slightly moistened with water, and rammed again. On top of the entire pillow, you again need to walk with a vibrotamper. A high-quality pillow is ready, you can put reinforcement and pour concrete. For this work, a device weighing from 100 to 200 kg is suitable.

The vibrating plate is self-moving: a - with a reversible mechanism, b - with a tilting vibration exciter.

It must be remembered that for the quality operation of any device or mechanism, proper care is needed. Dirt, small parts not replaced in time reduce the life of any equipment. Vibrotamper needs timely care. First of all, it is important to monitor the condition of the filter. Since it comes in only two types (paper and foam rubber), it is also easy to care for it.

You just need to shake off the paper filter, but the foam rubber filter needs to be washed in warm soapy water, dried and put back. The more often you wash and clean the filter, the longer the equipment will last. Do not forget about the oil in the gearbox and engine. It must be changed regularly for high-quality work of the vibrorammer.

Before starting work, the engine must be warmed up. You need to do this for about 5-7 minutes, after which you can safely get to work. For the full operation of the vibrating plate, it is desirable to have an anti-vibration handle.

When erecting any structure, specialists take into account all, even the most insignificant stages, which, during further construction, can become an important link in such a long process. They can even affect the operation of the building in subsequent years. At the same time, quite often experts ask this question: why do we need a foundation for a house and why should we devote so much time and effort to it?

The basis of any capital structure is reliable and on which it depends how durable and high-quality this building will be in the future.

At the same time, a special one, which is sometimes not given due attention, which is considered a gross mistake, is the capital basis of the entire structure being installed.

It happens: sand, gravel and concrete.

When designing a structure, it is necessary to provide for, and when laying a house, installation work is carried out under the foundation, when a pillow is laid, which still needs to be carefully tamped. Why does it need to be rammed? Then, so that a monolithic, strong and even slab is created under the base of the structure, the purpose of which is to ensure that the entire building shrinks as little as possible in the future for many years.

The base plate is of the following types:

sandy;
crushed stone;
concrete.

Each of them has its own advantages and disadvantages, but this does not mean that each of the listed types of pillows can be suitable for building any house. As a result, each developer is recommended to conduct a certain analysis and find out the condition of the soil. Why should such precautions be taken?

In this case, during the construction of a structure, it is recommended to take into account the climate, soil conditions, the presence or absence of underwater water, the general parameters and dimensions of the object, as well as various other factors. An improperly selected slab for the foundation, as well as a poorly installed one, can lead to irreparable consequences, this includes the destruction and subsidence of the entire base and the appearance of cracks on the walls of the house.

Numerous private developers prefer laying a pillow under a sand foundation, it is distinguished by its simplicity and low cost of building material. At the same time, such a solid slab has one drawback: heavy bulky buildings cannot be erected on it. But in private construction, when planning ordinary houses, there is no need to comply with such strict conditions, and therefore such a pillow has been popular among developers for many years.

Soil compaction is an important step in road repair or construction. The quality of the roadway or the strength of the foundation of the building under construction depends on it. For these purposes, gasoline vibrating plates are optimally suited - they are more productive than vibrorammers, but more maneuverable than vibratory rollers.

Soils are divided into:

Incoherent - sandy, gravel, coarse-grained, containing pebbles, etc.
Connected (viscous) - clayey, silty, peaty.
Mixed.

What to look for when choosing a vibrating plate:

Mass and centrifugal force - the depth of the rammer directly depends on them.

The width of the sole - the processing speed depends on this indicator. For passage along sites along structures or in places with difficult access, it is better to use a compactor with a narrowed base.

Reverse - the ability to move in the opposite direction (reciprocating). It is relevant when working in trenches - otherwise, it makes no sense to overpay for a given function - there is no damage left when turning on the ground.

The amplitude of the oscillation - the higher, the greater the impact force. For ground, a hand-held compactor with high amplitude and low frequency is better suited.

On the Diam Almaz website, you can buy a vibrating plate for soil and find out how much delivery costs in your region. It is possible to sell the machine in installments.
