Abstract: PROBLEM TO BE SOLVED: To provide a joiner which does not come off a strip even if the pitch of the strip is widened, and the watertightness is retained.
SOLUTION: A belt-like strip 14 is spirally wound round on the inside surface of a sewer pipe 12. Side borders of the strip 14 are jointed by a joiner 10. When the pitch of the strip 14 is widened e.g. by earthquake ground motion, a body 32 is broken off at the part of a notch 42 by an external force which breadthwise expands the body 32, before the fitting of hollow bar 34 of the joiner 10 to strip grooves 22 of the strip 14 comes off. Thus, expansion of the pitch of the strip 14 can be allowed. Even if the body 32 is broken off and each side of the body 32 is separated from each other, the gap between the separated sides can be sealed watertightly by a flexible part 40.

Abstract: PROBLEM TO BE SOLVED: To provide a process for lining the inner surface of a pipe to enhance inner pressure resistance. SOLUTION: In the process for lining the inner surface of the pipe by spirally winding a strip 1, which has joining rib pieces 2 and reinforcing rib pieces 6 provided to both side parts thereof, within the pipe, the strip 1 is manufactured by the extrusion molding of a plastic, a strip-like reinforcing steel member 7 is subsequently inserted in the gap between the adjacent reinforcing rib pieces 6 and spirally wound within the pipe to form a liner, and then a back filling material is injected in the region on the back surface side of the liner to fill the region.

Abstract: PROBLEM TO BE SOLVED: To provide a wall construction device for the circumference of a pipe capable of constructing a homogeneous wall around the pipe and, at the same time, shortening a construction period of time at a low cost.
SOLUTION: A circular opening section of a gutter pipe is closed by the whole circumferential seal 1 to separate the ground G from the inside of the gutter pipe Z, the whole circumferential seal 1 is pushed away by a guide holding section 11a of a holding member 11 to project a guide member 14 in the direction of F. After a cutter 15 is projected in the direction of the F along the guide member 14 by a cylinder 16 for coming in and out, the cutter 15 is turned in the direction Q by a turning unit 2 to make it eat into the ground, and while moving the cutter 15 in the direction of D along the guide member 14 in a state to remain unchanged, the ground G is excavated to form a trench M and, at the same time, the inside of the trench M is injected and filled with a kickback material Y from injection pipes 17a and 17b. When such a series of processes are repeatedly carried out, finally the circular trench M filled with the kickback material Y around the gutter pipe Z is formed, and then, when the kickback material Y is solidified, the circular wall is constructed around the gutter pipe Z.
