What Does Thrust Wall Mean?
The thrust wall is the base against which the main jacking station's hydraulic jack pushes when the jack is ramming a pipe section through the soil. The trust wall is essential in pipe jacking.
Pipe jacking is a trenchless process whereby a specially designed pipe is pushed through the ground by a specially designed hydraulic jack that operates on the horizontal plane rather than the vertical plane. The thrust wall is positioned in the access pit before the jack is lowered into the pit.
