METHOD AND APPARATUS FOR REGENERATING PIPELINE SUCH AS DRAIN PIPE

摘要

PROBLEM TO BE SOLVED: To reduce the amt. of a pressure fluid injected into a repairing material by inserting a flexible insertion member for narrowing an internal space into the repairing material to arrange the same to hermetically close the space. SOLUTION: A reparing material 13 having length equal to that of a pipeline 10 is inserted into the pepeline 10 to be arranged. The repairing material 13 has a flexible cylindrical shape impregnated with an uncured curable resin. A supply hose 17 supplying a pressure fluid L such as water or steam into an internal space E and a discharge hose 19 discharging water or steam in the internal space E are connected to the repairing material. The hoses 17, 19 are connected to the pressure means 21 of a water supply vehicle 20 forcibly supplying and discharging the pressure fluid L. When the pressure fluid L is sent into the internal space E of the repairing material 13 by the pressure means 21, the repairing material 13 is pressed to the inner wall 10A of the pipeline. By this constitution, the amt. of the pressure fluid injected into the narrowed internal space of the repairing material 13 can be reduced and regeneration work for the pipeline such as a drain pipe can be economically performed within a short time.
