A base crawler machine with a vertical cutter post attached to it creates TRD soil mix walls by mixing them in place.
- Control groundwater
- Reinforce excavations and structures
The vertical cutter post resembles a large chain saw and is inserted in sections vertically to reach the design depth of the wall. The crawler machine moves along the wall alignment as the cutter post cuts and mixes the soil with a cement-based binder slurry. This mixes the entire soil profile, eliminating stratification, and creates the soil mix wall.
