compacting soil with compactor

Compactors and principles of soil compaction in confined spaces

Construction requires solid ground free of any drift, subsidence or erosion. Therefore, it is not possible to build on a land just because it is flat. To prepare the ground for construction, they are compressed during operations.

Along with soil compaction operations, you can have a perfectly flat and solid surface that can no longer withstand the high weight of structures. A device that can level the soil surface for construction is called a compactor.

The word compactor also comes from the English meaning of this name. The literal meaning of compactor in English conveys the concept of compression or compressor. Therefore, a compressor can be expected to compress soil, aggregates, sand, and sand.

The importance of using a compactor in construction is when we expect soil subsidence, whether due to the weight of the structure or erosion, and perhaps multiple subsidence.

If we build a structure on the ground that has not been thought of for any reason and there is a possibility of soil subsidence, in the near future, along with soil subsidence, we will see deep turbulence on the structure and in more serious cases, sudden destruction of the structure.

Therefore, it is very serious to make sure that the soil is completely strong before attempting to build any structure on any ground. One of the most important ways to achieve this is through compacting the soil.


Manual compactor and construction applications

Probably all human beings have witnessed the operation of heavy rollers in large-scale road construction operations for once. As expected from the simple operation of a heavy roller, that equipment can compress soil or any other surface by relying on its very high roller weight.

But the rollers are suitable for large spaces, large areas and road construction operations. This large and heavy equipment cannot be used in construction operations or small spaces.

Soil compaction is limited to spaces where a variety of compactors such as plate compactors, tamping rammers, and kangaroo compactors are designed and manufactured.

Therefore, it is possible to benefit from different types of compactors in limited building spaces such as yard construction, landscaping, parking, soil strength in the construction of building structures, and so on.

Of course, this equipment is designed and produced according to the needs of consumers in various working conditions with different capacities, and depending on the needs of the project, one of these various designs of the compactor can be purchased and used.

Therefore, apart from fully understanding how the compactor works, it may be very useful to be familiar with the types of this equipment.

Principles of soil compaction with a compactor

Soil compression by a compactor is not such that for any surface with any condition and only with the use of a simple compactor, soil compaction is carried out. Optimal compressor operation requires some precautions.

Prerequisites whose correct conditions can play a decisive role in the final desired results. For this purpose, the first step can be to ensure the integrity of the soil.

This integration will be partially achieved by absorbing a significant amount of water.

In this way, before the compactor can operate, the ground will be irrigated as much as the soil absorption capacity allows. Then, after sufficient confidence in the maximum absorption of water by the soil, leave this soil rich in water for 24 hours so that the water settles completely in it and the soil retains only the moisture of the water.

Wet soil is more acceptable than dry soil. Therefore, the compactor can be operated with moist soil. Of course, in the operation of the compactor, you have to take seriously the fact that the desired space is accompanied by moist soil. The compactor will not be able to operate on muddy ground.

Because apart from getting caught in the mud on the ground, there is a possibility of spraying mud and water around the device during the operation of the compactor.


What are the types of compactor?

Compactors are classified into two major groups: plate compactors and tamping rammers, based on the type of design in the body to the structure of the device and how the compression works. The compactor, of any kind, will compress the soil surface with deep vibrations.

These vibrations are so intense that they can cause slight and sometimes deep vibrations on the handle of the compactor. Therefore, it can have long-term consequences for the device's operators. To prevent this from happening, often any operator will not work with a compactor for more than a few hours.


Buying plate compactors or tamping rammers?

Being familiar with plate compactors:

The plate compactor uses a heavy steel plate to hit the ground. A gasoline engine and sometimes a diesel that comes with a compactor. This heavy steel plate can be moved up and down at adjustable speeds and will deal a heavy and deep impact on the soil surface in each work cycle.

When buying a plate compactor, you should pay attention to points such as the amount of impact force required, the amount of surface area required for compression operations and motor components along with the type of engine, which can be gasoline or diesel.

Keep in mind that page compactors are designed and manufactured for limited spaces. Therefore, they cannot be used for use in large spaces such as road construction.

 Being familiar with tamping rammer:

In different types of plate compactors, you have seen a specific frequency on the steel plate, but in another type of compactor, known as a tamping rammer, it is accompanied by a shock force that compresses the soil.

In the operation of a tamping rammer, sometimes referred to as a kangaroo compactor, you can see leaps and bounds from the device's foot, which will be accompanied by high weight of equipment and pounding on the soil surface, the process of soil compaction will take place.

Just like a frog during an operation, large mutations occur from this equipment. A tamping rammer is used for operations in confined spaces and low-maneuver locations. Therefore, they are very suitable in canals, foundations, etc.

They have good plowing depth and are easier to transport than other types of plate, but they can never be used to pound the soil on large areas of land.
