Varieties of surface vibrators for soil compaction

How to use it correctly?

A hand-held vibrating machine is used for various purposes, such as tamping crushed stone, using a technique, sand is compacted, and clay is tamped. You can often see how paving slabs are laid using this technique. In order to use the maximum capabilities of the equipment, the operating instructions are preliminarily studied. Let us consider the use of a vibrating plate on the example of a complex work on laying paving slabs.

  • Preparatory stage - determine the contours of the path where the paving slabs will be placed. Place beacons that take into account all the unevenness of the surface relief for laying.
  • Grading - remove the topsoil and fill in fine gravel.
  • Drainage - so that moisture does not affect the tiles, the drainage layer is compacted so that it is moisture-proof.
  • Restriction by curbs - for this, a curb is installed along the edges of the path, which will limit the mobility of the tile elements.
  • Filling a sand layer - this is necessary to level the working surface. The sand is also subject to compaction, and its layer is 40-50 mm.
  • Laying tiles - at this stage, tiles are laid out in even rows on the surface of the sand.
  • Tamping tiles in the ground - for this purpose, a damping polyurethane mat is mounted on the sole of the vibrating plate.

After the paving slabs are finally laid and a vibrating plate is passed over it, a new layer of dry sand is poured over it to seal the gaps between the tiles. Carrying out construction or laying work using manual vibratory ramming equipment requires the implementation of certain rules so that the work is done efficiently, and the equipment lasts as long as possible.

Work must be carried out in a planned manner.

It is important to start the vibratory plate and let the engine run a little at idle, after which you can start compaction of the soil surface. In this case, you should always make sure that the belt tension is correct; if the belt traction looses or breaks, the compaction process cannot be performed.

In the process of work, it so happens that it is required to compact several layers of a cushion from the ground

Each layer must be processed separately, and the height of such a layer must correspond to the characteristics of the rammer. If the layer is more than stated in the capabilities of the technique, then its high-quality compaction will not work. You will need to remove the top of the pillow, tamp the first layer, then pour the next layer on top of it and seal again. This is done until the entire thickness of the pillow has been processed.
The number of passes through each layer to be compacted should be at least 5-6 times.

Vibratory rammer selection

When choosing, take into account all the technical characteristics. With a large shoe it will be more convenient to work in large areas, with a small shoe - in narrow ones. A rammer with a higher capacity will process higher density surfaces faster. The gasoline rammer has the highest impact frequency. A small vibratory rammer with a low weight is suitable for narrow places, and a more powerful and heavy rammer for trenching and drainage.

The price of a vibratory rammer is influenced by many factors: purpose, brand, performance, and also the place of purchase. For example, gasoline has a low cost, decent power and low operating noise.Such a rammer is capable of working in many conditions, since it does not need a power supply. The diesel option is not so popular because it is more expensive and has a higher noise floor, however, it saves quite good fuel costs. Someone's conditions allow the use of electric.

There is a large selection in Moscow. To find out how to buy a vibratory rammer at an affordable price, you can, for example, first look through the online sales catalog in Moscow. If there is a need to buy in bulk, then in Moscow you can buy a vibratory rammer at the best price. You can find one of the best deals with descriptions, reviews, photos and store addresses. If you buy a vibratory rammer in Moscow, it will be an excellent alternative to expensive equipment.

Design and principle of operation

Structurally, the vibrating compactor has an electromechanical eccentric that creates vibrating mechanical vibrations. With the help of a belt drive, the torque from the engine is transmitted to a rigidly fixed eccentric. The resulting vibrations transmit vibration to the working metal base of the unit. The entire surface area of ​​the slab acts on the sealed coating.

Expert opinion
Vasily Kuznetsov

Equipment for construction works has increased reliability requirements. Therefore, the design of the vibrating plate should be simple, maintenance easy, and the principle of operation clear.

Views

Vibratory plates can be divided into several types:

Vibratory plates: 1-Gasoline 2-Diesel 3-Electric

Energy use

Gasoline

An economical option, it is in the greatest demand (prices are lower than diesel analogues). They can move freely around the work site (they are not tied to a power source, unlike electric vibrating plates), they are able to work in frost and heat.

Disadvantages: heavy weight, making a lot of noise during operation.

Diesel

Easy to operate, reliable, durable, independent from the power source.

Disadvantages: heavy, make a lot of noise when working. They may not work well in the cold.

Electrical

They are lightweight, low noise, and environmentally friendly. Can be used indoors (since there is no internal combustion engine, there is no pollution from exhaust gases).

Disadvantages: the working area is limited by the length of the power cable; are used less frequently, as additional electrical equipment is required.

By way of travel:

Reversible

More maneuverable (the ability to reverse without turning); indispensable in narrow aisles.

Disadvantages: heavy weight, high price.

Translational

They only move in the forward direction. Vibratory plates of this type are cheaper and lighter.

Disadvantages: Additional space is required for turning.

By weight:

  • Lightweight (up to 75 kg) - used for compaction of soil with a thickness of 10-15 cm (for finishing and landscaping).
  • Universal (75-90 kg).
  • Medium weight (90-140 kg) - used for layer-by-layer seals up to 35 cm thick.
  • Heavy (200 kg or more).

Top Models

Vibratory rammer Hyundai HTR 140

It efficiently ramps both hard soil and loose coatings. The impact force is 14 kilonewtons at a frequency of 680 beats per minute. A high-quality engine will not let you down even in the most difficult working conditions. The overhead valve system of cylinders does not require much effort when starting the engine. All bridles and elements are fixed on a thick frame, which has spring shock absorbers, which significantly dampens vibration during operation. The frame and the compaction plate are made from durable grades of steel, because these elements are subjected to enormous stress during operation.

Masalta EMR70H

A small but high performance vibro leg powered by an original Honda engine.High-quality components allow the equipment to operate in conditions of increased dustiness and humidity, while these factors do not in any way affect the reliability and durability of the device.

AGT CV 65 H

The best option for use in the construction industry, as well as for road repair. The engine does not have as high power as other models, therefore the weight of the device is not so heavy - 10 kg. A compact vibro-leg, which is ideal for residents of country houses and summer cottages - with the help of this tool you can equip your local area, prepare a site for the foundation of a bathhouse and other various buildings.

Centaur VT95

It is produced in Ukraine, so the cost of such a tool is significantly lower than that of European competitors. The low cost is also explained by the fact that the impact force is only 12 kilonewtons, while the vibration frequency is 270 beats per minute, which is also not impressive. Despite its mediocre characteristics, this model can be recommended for excavation work, as well as for compacting bulk materials and small ditches.

Biedronka UW7814K

The tool is made in Poland, has a Japanese engine Honda GX160, which is characterized by minimal fuel consumption. The drive is well cooled and therefore does not heat up even under heavy overload conditions. In case of insufficient lubrication, the engine automatically shuts off, which avoids damage to the vibro-leg due to unsatisfactory maintenance.

If necessary, the device can be moved to a height using the transport hook, which is included in the kit. This model is specially designed for large-scale construction work - the compaction of asphalt, concrete and tiles is fast enough, which reduces labor costs.

Where is it applied?

A manual vibratory rammer is used to compact the soil to a depth of at least 60-70 cm.This device is capable of compacting not only sandy or soil cover, but also large crushed stone, therefore the device is used for crushed stone, for a lawn, for sand for building a foundation or when preparing a site for backhoe loader.

Often a vibratory rammer is used in places where free space is extremely limited or there is a risk of damage to previously equipped communications:

  • works on the arrangement of the tram track;
  • arrangement of pedestrian zones and sidewalks with tiles, paving stones;
  • preparation of the soil surface for the organization of the foundation;
  • partial repair of the asphalt pavement;
  • installation of underground communications;
  • compacting the soil along the walls of the building;
  • arrangement of the basement;
  • equipment of wells, hatches, poles.

At construction sites, a manual vibratory rammer is used in all cases when large equipment, due to its size, cannot get close to the working area. Manual vibratory rammer is used only for free-flowing fractions - sand, soil, gravel, but is not used for compaction of soil, which contains a large percentage of clay impurities.
