Excavation support or earth retaining structures are vital where deep excavation is created and arrangement of necessary slope is not possible. Given below, the details of different types of excavation supports.
What Are Excavation Supports?
Usually, to develop a structure either over the ground or underneath the ground, excavation of soil should be arranged in the ground.
The excavation may come in the form of shallow or deep on the basis of our need. But when the soil is dug deeply, there is a chance for collapsing of the soil from the sides of excavated area because of low strength.
Types of Excavation Supports: Usually, the following methods are mostly used for providing excavation supports-
Soldier Pile and Lagging: Soldier piles refer to I-sections which comprise of web among two flanges. These I-sections are drilled into the ground encompassing the boundary of an excavation. The piles are delivered to the point slightly under the necessary excavation depth.
Wood lagging is applied among the piles. The lagging comprises of long timber sheets or planks which are arranged behind the front flanges of piles to provide well support to the soil among the piles.
