What Is Soil Nailing In Civil Engineering?

 Nailing is an innovative method based on anchoring and twisting rocks to stabilize the excavated areas. It was first built in the 1960s by Australian engineers to stabilize the walls of new tunnels. At first, it included three rebar installation systems, cement grout injection and shotcrete application. With the passage of time, nailing has been accepted globally and has been significantly used in different parts of the world, including Iran, especially in urban structures.

Rebar is one of the basic components in the construction industry and is used in the construction of all types of structures. One of the main applications of rebar is to nail the soil in the process of building foundations and foundations.

The nailing method in excavation is one of the methods that can be used as a guard structure to prevent the collapse of the excavation wall. Another name for nailing is the back sewing method, this method is very similar to the anchoring method. Nailing operations have been used since three decades ago. In this method, we drill step by step and from the top to the bottom of the pit.

Application of nailing or nailing

Different methods of stabilizing trenches always face different challenges. Of these, nailing or nailing is the preferred choice of most employers in the road and construction sector due to its technical and economic advantages, which provides the reliability factor of excavation walls in the best way without creating conflicts within the scope of the project. Applying current knowledge of the nailing system and post-tensioning of the nail elements made it possible to reduce the change of locations adjacent to dilapidated buildings and high-traffic roads. This technology, which is called anchorage, has become the only option for stabilizing wells above 25 meters by using multi-stranded strands instead of rebar in boreholes.
