Soil Anchoring Mean?
Soil anchoring is the process of inserting steel bars through holes drilled in the shoring wall, such as sheet piles, to anchor the wall to a stable, rocky zone. Trenchless construction methods do not require trenching, but they do require an entry pit to install the rig and launch the installation, as well as an exit pit to retrieve the pipeline on the other side. These pits need to be secured to prevent the excavated sides from collapsing.
Trenchlesspedia Explains Soil Anchoring
Soil anchoring is important for slope stability and prevents the structure from collapsing. It is used to provide temporary structural support to the sidewalls of the launch and exit pits excavated during a trenchless installation project. The steel bars used for anchoring are inserted into the holes provided in the shoring wall and grouted into position. An anchor head is threaded into the exposed end of the steel bar and then tightened to anchor the shoring wall securely into the surrounding soil.
