Land Movement is understood as the set of actions to be carried out in a land for the execution of a work. This set of actions can be performed manually or mechanically. Prior to the start of any action, the Stakeout Works must be carried out, provide access to machinery, trucks, ramps, etc. A movement of the earth consists of excavations and emptied fundamentally, which are carried out on a piece of land before beginning a work. The excavations of the Earthworks are carried out before beginning with earthworks. First, it is usually clean the land of plants, weeds or garbage that may be in it. This action is called clearing, after this process, the excavation begins, which aims to reach the foundations, it can be done in two different ways: manually, using pick and shovel; or mechanically with the excavators.
Types of Earthworks Excavation
There are different types of Earthworks excavations:
– Dismount. The clearing consists in the movement of all the lands that are above the gradient of the starting plane of the building.
– Emptying. The emptying is carried out when the starting plane of the building is located under the ground.
– Terraced. The earthwork is executed when the terrain is below the level of the construction site and it must be raised to the same level.
Earth Works are usually carried out by mechanical means with the appropriate machinery in each case. You must take into account the final elevation of the excavation and leave the land level since it would be very costly to have to re-fill the executed. It is important to know the angle of natural slope of the terrain, especially those of little cohesion, to know the exact location when digging, leaving wall faces.
It is usual that before beginning the movement of earth, an action is made at the level of the surface of the land, cleaning of bushes, plants, trees, brush, weeds, and garbage that could be found in the ground; This operation is called clearing and clearing. When the terrain is already clean and free, the stakeout is carried out and the excavation begins.
Earth Works Excavation by Tanveer Ahmed Road Contracting
Excavation is the movement of earth made in the open and by manual means, using pick and shovels, or mechanically with excavators, and whose purpose is to reach the starting plane of the building, i.e. the foundations.
The Earth Works excavation can be:
The clearing is the movement of all the lands that are above the level of the starting plane of the building.
The emptying is carried out when the starting plane of the building is below the ground.
The earthwork is done when the ground is below the starting plane of the building and it is necessary to bring it to the same level.
It will take into consideration the following items:
Characteristics of the land, such as cohesion, density, compactness; they are factors that influence the performance of the machinery. Intrinsic factors of the terrain, such as settlements, groundwater levels, plastic areas, which can increase the measurement. External factors, such as climatic factors, aerial or underground laying, neighboring buildings, traffic, which can cause the excavation to be paralyzed. Ways to execute the excavations, taking into account depth, section, height, etc.; this will guide us towards the most appropriate type of machinery to use.
