To provide a construction method for repairing passage facilities, which increases the filling pressure of a filler so as to shorten the filling time thereof, and which causes the thickness of the filer to be circumferentially uniform so as to uniform the strength of the passage facilities circumferentially after repairing.
A plurality of sheathings 10 are attached to the inner wall surface of a pipe (passage facilities) 1, and a plurality of inner wall panels 12 are fixed to those sheathings 10 so as to be laid along the inner wall surface of the pipe 1, and a filler 15 is filled between a gap S defined between the inner wall panels 12 and the inner wall surface of the pipe line 1, and is then cured. With this arrangement, the inner awl panels 12 are fixed and supported to the plurality of the sheathings 10, and accordingly, they can be prevented from being deformed by the filling pressure of the filler 15, thereby it is possible to increase the filling pressure of the filter 15 in order to efficiently fill the filler 15 into the gap S within a short time. Further, the gap S between the inner wall panels 12 and the inner wall surface of the pipe line 1 can be set to be circumferentially uniform so that the thickness of the filler 15 filled in the gap S can be uniform. Thereby it is possible to cause the strength of the pipe to be circumferentially uniform after repairing.
