<p><P>PROBLEM TO BE SOLVED: To easily form a lining layer causing little pressure loss of a fluid in a pipe and easily securing desired pressure withstanding property even in an existing pipe with a bent pipe part. <P>SOLUTION: In this in-pipe lining construction method for forming the lining layer C in the existing pipe A, a corrugated pipe 2 is inserted through in the existing pipe, and a lining pig 9 is moved in the corrugated pipe to apply an unhardened lining material 8 to the inside of the corrugated pipe so as to fill the inside of outward protruding pipe wall parts 5 protruding toward the outer peripheral side of the corrugated pipe. The applied unhardened lining material is hardened to form a hardened lining material layer 7 inside the corrugated pipe. <P>COPYRIGHT: (C)2003,JPO</p> |
