What is the 3S Segment Method?

Construction Method Video

After assembling hard plastic segments with bolts and nuts on the inner surface of facilities such as circular pipes and box culverts (pipe culverts, manholes), a cement-based grout is injected between the inner wall surface of the culvert facility and the segments. It is a construction method that integrates the pipe facility, grout, and segment, and enables the restoration of high-strength, super-large pipe facilities.
