Soil compactor: types and applications

Soil compactor belongs to the class of special equipment for repair and construction and road works. First of all, such a machine is designed to stabilize and compact ground masses: bases of sand, gravel, clay, rock or rock crumb.

Classification

The main part of the roller is a roller, which is a large cylinder, installed in place of the wheels. Each machine is equipped with two rollers - the lead and the slave. It is depending on the design features of this working body and classify the soil rollers.

Ground roller: types

1. With smooth rollers (the working surface of the cylinder is smooth). Such a machine is designed for compacting loose ground and asphalt-laying works.

2. With cam rollers: the surface of the working organ is covered with truncated pyramidal projections (cams). It is used both for leveling and compacting soft soils, and on harder frozen soils.

3. With latticed rollers: the surface of the cylinder is profile - latticed or in the form of cast discs. Such a soil compactor is designed for those types of work where, apart from compaction, the fragmentation of large soil fragments is required. This technology provides good compaction.

4. With pneumatic wheels. The working body consists of a system of wheels separated by gaps.

If the soil roller has several different rolls, it is called a combined roller. Another roll is classified according to the number of rolls per one-, two-, and three-rollers.

Separately it is necessary to single out a vibratory soil roller. Recently, it is this type of special equipment that has become widespread. A distinctive feature of such a rink is that the working member vibrates, creating an additional load on the ground base. This allows you to make one pass where a conventional ground roller should make two or three. In fact, this technology helps several times faster to carry out road and maintenance work without loss of quality.

There are rinks and in size. There are miniature hand cars with a working cylinder length of only 20-30 cm, and there is a powerful self-propelled technique with superheavy rollers (more than 15 tons) and a working body length of 1.5 meters.

A ground roller is a special technique that helps considerably simplify the process of creating roads, grounds, foundations, car parks and other objects. The only thing this type of car can not boast is speed. In modern models it is only 14 km / h, which is quite a lot, if you remember that most of the rollers can not move at a speed above 3-5 km / h.

And the last question: how much does a compactor of soil? The price can fluctuate greatly, depending on the particular type of machine, specifications and brand of the manufacturer. Price range - from 1,600 thousand rubles. Up to 4 million rubles. If the soil roller is only needed for one-time works, you can rent a machine. The cost of rent is from 1000 to 15 000 rubles. You can choose an option cheaper, for example, to compact the soil for the tracks around the house suitable manual asphalt compactor (rent - from 800 rubles.).
