PIPE CLOSING IMPLEMENT FOR BURIED-PIPE FILLING METHOD

摘要

PROBLEM TO BE SOLVED: To enhance the efficiency of a buried-pipe filling method for filling an internal space of the buried pipe by injecting a filler such as slurry mortar into the unused buried pipe from its one end, and to reduce working hours.

SOLUTION: This pipe closing implement 1 comprises: a pipe 2 which can be inserted into the pipe opening 11a of the unused buried pipe 11; a fixing implement 6 for fixing the pipe to the pipe opening; and a seal member 7 for closing a gap between an inner surface of the pipe opening and the other end-side outer periphery of the pipe inserted into the pipe opening. The pipe closing implement 1 is fixed to the pipe opening 11a; the fluid filler is injected into the unused buried pipe 11 through the inside of the pipe via a hose 12 which is connected to one end of the pipe 2; and a backflow of the filler is stopped by a check valve 5 which is provided inside the pipe 2.
