PROCESS FOR REHABILITATING SEWERAGE PIPE BY MOLDING

摘要

The present invention is to rehabilitate the castle type hasugwanro and structural deterioration as the feature value away hasugwanro relates to a regeneration method by trenchless construction method, the outer end portions index (止水) of the manhole of hasugwanro to complement overall investigating hasugwanro clean by the pre-treatment, such as, and smooth, and then, during the installation through the one manhole in the synthetic resin tube molding machine and extrusion-molding the synthetic resin tube with an inner diameter condition hasugwanro be repaired by installing the traction vehicle pulling the forming tube through the other manhole the outer space of a gear pull the leading end of the forming tube by the traction vehicle to a speed consistent with the forming speed handling and then forming tube by sealing both ends of the molding tube, the hot air in the interior of the co-encapsulation molding tube for injecting fillers or adhesive the hayeoseo be formed tube is joined integrally fixed to the inner wall of the injection expansion sikieo hasugwanro There are no joints (connecting portion) with a smooth inner surface that sewage flows smoothly, but one can be fully embedded as a regeneration of the fuse do not have a partially leak.
