Retaining wall is a structure, which is artificially created to resist soil pressures when some change in the ground elevation exceeds angle of repose. Cantilever wall is most common of these types of structures.
Soil nailing is one such technique to reinforce retaining wall. They must be planned well by soil nailing contractor and constructed in such a way to resist pressures from water as well as soil.
Important basics about Soil Nailing Technique
While going for soil nailing, the two most important tasks done by soil nailing contractor is planning and designing. The sole purpose of these retaining walls is to restrict natural movement of the soil down the slope as a result of gravity.
The pressures are generally low at top of wall and can increase towards the base. However, if they are not installed correctly, the retaining wall may lead to complete collapse or tipping as a result of differences in force on the surface of the wall.
Retaining wall may be constructed by making use of number of materials including concrete blocks, stones, logs, wood planks, and a lot more. The materials and the height of wall can be determined on basis of the numerous conditions including type of soil, angle of slope, etc. It is even important to ensure that drainage solution is in proper place for soil above the wall.
A retaining wall can be constructed in a series of levels or steps enabling unique creative outlet for the planning shrubs, flowers, and any such decorative elements. Stepped walls have been proven to be a more effective form of the erosion control.
