PROBLEM TO BE SOLVED: To provide a pipe surface cover that is excellent in durability and weather resistance, reduces costs and working hours, and is hard to peel off when it is superposed and bonded, and a temporary pipe and a method of constructing the temporary pipe. SOLUTION: A composite sheet 22 is formed by interposing a polyethylene woven fabric 25 between a polyethylene or polypropylene film layer 24 and an aluminum foil layer 26 and integrating them together. An adhesive layer 23 is arranged on a surface 26a of the aluminum foil layer 26. A molded heat insulating material 11 of foam resin is brought into close contact with an outer surface 10a of a pipe body 10 so as to cover the outer surface 10a of the pipe body 10. The molded heat insulating material 11 is secured to the pipe body 10 by means of fixing members 12. The composite sheets 22 are bonded to the entire outer surface 11b of the molded heat insulating material 11 continuously in series in the lengthwise direction of the pipe body 1 by the adhesive layers 23. Dampproof adhesive tapes 14 are bonded to side edge portions of the composite sheets 22, and cover tapes 15 are bonded to end edge portions of the composite sheets 22. COPYRIGHT: (C)2007,JPO&INPIT |
