The "Bax Method" of inserting a rehabilitation pipe into large-diameter sewer pipelines.

The "Bax Method" of inserting a rehabilitation pipe into large-diameter sewer pipelines.

This is a technology for rehabilitating pipes with excellent acid resistance and self-supporting capabilities, which are inserted and rehabilitated using a propulsion device. It can be constructed while using the sewage system, eliminating the need for water replacement.

This is a pipe rehabilitation method classified as a sheath pipe method, which involves inserting a corrosion-resistant rehabilitation pipe into existing large-diameter sewer pipes using a push (jacking) device to construct a new pipe. 【Applications】 ● Reconstruction and extension of the lifespan of aging or damaged sewer pipes (Ø800 to 2000) ● Strength restoration ● Improvement of water-tightness against infiltration, flow characteristics, corrosion resistance, prevention of root intrusion, and seismic resistance ● When it is necessary to maximize the flow cross-section inside the pipe 【Features】 ● It is a self-supporting pipe method that achieves the necessary strength against soil water pressure with the rehabilitation pipe alone. ● Construction can be carried out without stopping sewer service (at depths of 30 cm or less), making it suitable for large-diameter main lines where water replacement is difficult. ● Being a jacking method, it maximizes the flow cross-section inside the pipe (by adopting a thin-walled structure of the back pipe, it secures a flow cross-sectional area equivalent to or greater than a pipe one size smaller than the existing pipe). ● The back RC pipe, made of thin-walled RC structure with high-strength concrete, has a strength exceeding the standard breaking load of JSWAS A-1 (Type 1). Additionally, the back FPRM pipe, made of reinforced plastic composite structure, has strength equivalent to JSWAS K-2 standards.
