The RJS method is constructed through porous pipe and front end. The soil is pre cut by high pressure water jet.
The soil is cut by high pressure mud jet for two times, and the high pressure air is mixed with hardened material to form a pile body.
RJS method for open areas of high efficiency,large diameter, ultra-deep construction.
Using the entire online construction management system, automatic monitoring and controlling of construction parameters.
RJS method is a kind of water-tight reinforcement method that adapts to small space, high torque, full circle semicircle and fan-shaped construction.
