<p>PURPOSE:To embody the strip material capable of confirming the positional relation of a lock male part and a lock female part when a worker is situated in an existing pipe to line the inner peripheral surface of the existing pipe with the strip material by a sticking system and capable of rapidly and certainly performing lining work. CONSTITUTION:A fitting ridge 13 is provided to one side edge part in the lateral direction of the base plate 12 constituting a strip material 10 and a fitting recessed part 18 is provided to the other side edge part thereof. A hinge part 122 is provided to the base plate 12 at a position displaced to the inside of the lateral direction from the position of the fitting ridge 13 by a proper distance and the ridge 13 and the peripheral part are made bendable in the direction becoming the inner peripheral surface at a time of the formation of a pipe. In such a state that these parts are bent, the strip material 10 is rolled in a coil shape and the fitting ridge and the peripheral part thereof are folded back to be engaged with the adjacent fitting recessed part 18 of the strip material to form a pipe.</p> |
