RDS Cast-in-Situ Diaphragm Wall Method

Adopting the high quality and accurate underground continuous wall of the RDS (Underground Rigid Diaphragm Wall Construction System), in addition to the conventional temporary role as a retaining wall and a waterproof wall, it can be used as a structure of reinforced concrete with high rigidity.


  • By managing with the construction with the excavator construction control system, drilling precision management system, concrete placing system, stable liquid management system that are developed for this method, high quality and accurate underground continuous wall can be constructed.
  • Because underground continuous ground walls are used for the main structure, the underground space can be used more widely.
  • The simple joint construction method brings excellent water proofing.
