Compactor is another tool that plays a key role in the construction industry and in the construction requirements of a building.
Of course, in another view, this device should not be limited to construction, but also helps workers and contractors in road construction and some other uses.
This device may be somewhat anonymous to the general public, but the vast majority of people involved in road or construction projects are well aware of what a compactor is and what it does.
Of course, it should be noted that in foreign terms, the compactor includes a wide range of tools and machines, but in this note we intend to focus on the manual compactor.
After looking at the nature and operation of the compactor, we will review the different types of this device and introduce them. So if you want to get acquainted with Compactor in simple language, we suggest you stay with us until the end.
Taking a look at the nature and function of the compactor
The basis of the work is the creation of vertical force per unit area. This definition may be a little confusing, so let's explain it in simple language.
When a plate compactor or any other type of device is started, the heavy bottom surface that is in contact with the ground vibrates very quickly in the vertical direction and goes up and down.
The combination of the weight of the surface in contact with the soil with continuous blows up and down causes the empty space between the soil layers to be minimized in a certain period of time (short) and you can see the looseness and integrity of the soil.
Of course, sometimes it is possible to add certain chemicals to the soil to help speed up the compactor process so that the soil adheres faster and forms an integrated plate.
However, in many models, the water pump built into the manual model continuously adds water to the soil during vibration so that the soil reaches a uniform state sooner.
In addition, the force required for this continuous vibration is enormous; this force must be such that it can still exert a great deal of pressure on a large scale.
Physically and mechanically, a force whose unit is Newton will be converted to a pressure whose unit is Pascal divided by the unit of square meter, which represents the area of the surface.
Looking at this equation, you will see that if the level increases, the pressure is needed to keep the pressure high, so that a large amount of force is applied to the surface.
Different types of compactors
This device, like any other mechanical and functional device, has different types depending on the different needs of users and buyers.
It should be noted that each type of compactor may be designed for a specific application, but in many cases it is possible to use them instead of each other.
However, this should happen depending on the diagnosis of the experienced operator. Here are two common types:
Tamping rammer
The Tamping rammer is a mechanical machine for soil compaction that operates differently from a plate compactor. In this type, instead of using vibration to create a smooth surface, it uses the force of impact.
The way it works is that in the so-called compactor foot, the tamping rammer is repeatedly collected and then dropped down.
This ups and downs are done at high speed and with a lot of force. Due to the special design of this device, it was mostly used in situations where it is difficult to access or there is not enough surface to contact the screen compactor.
Also, due to the low contact surface of the tamping rammer, it is more portable and easier to work with.
Plate compactor
The screen compactor is a more common model of this device, in a way that the public often refers to when it comes to naming the screen model compactor.
The basis of this device is implicitly described in the previous section. In the plate model, vibration is used to smooth and compact the soil surface.
What is the difference between a tamping rammer and a plate compactor?
Many people go to experienced people and experts with this question but do not find a clear answer. Be careful, you will notice the difference in performance between the two devices if you notice the difference in soil type.
We are faced with two categories of soil when working:
Granular soil
Cohesive soil
Granular soils such as sand and granules, which are soft and can be compacted without the need for wetting, quickly separate and disperse during grabbing and punching. But cohesive soils are usually very clayey and normally come together with a kind of cohesiveness and firmness.
It must be moistened to ensure that the soil is properly compacted. In cohesive soil, if the moisture level is very high, the cohesion is so high that you will see the formation of air bubbles. However, the difference in performance between the two devices can be examined in detail:
The tamping rammer is suitable for working with cohesive soil due to the smaller size of the bottom plate. The smaller your plate or insole, the more focused and direct you are able to apply force.
The tamping rammer has the ability to compact the soil to a greater depth and is more suitable for work processes on surfaces that have more limited access.
The plate compactor is more suitable for working with granular soils and due to its constant vibration, it is possible to compact this type of soil.
The plate compactor operates on a larger surface and therefore usually has more weight and power, the speed of working with it is somewhat faster; although it is more difficult to work with. Larger volume and larger dimensions are a challenge when working with this type of device.
