TRD method
Continuous underground wall construction possible at a height of 10m and maximum depth of 60m with machinery!
The "TRD method" is a construction technique that involves moving a cutter post installed underground horizontally while excavating the ground with cutter bits attached to a cutter chain, mixing and stirring the solidifying liquid with in-situ soil in a vertical direction, and creating a solidified body in the ground. 【Features】 1. Outstanding stability 2. High-precision construction possible 3. Cost reduction achieved through excellent excavation capability 4. Homogeneous wall quality in the depth direction 5. Continuous construction without misalignment 6. Flexible setting of core material spacing Outstanding stability, high-precision construction, and excavation capability! A ground continuous wall method adaptable to various applications! *For more details, please feel free to contact us.*
