WATER STOPPING METHOD OF STRUCTURE SUCH AS PIPE CONDUIT

摘要

PROBLEM TO BE SOLVED: To easily and surely stop water in a state of reducing secular variation at a water leakage part in a case when water leakage is found on a pipe conduit such as a drain pipe. SOLUTION: A groove 21 having a pair of parallel side faces opposite to each other, is formed on an inner periphery of a water-stopped part of a structure such as pipes 10, 11. The groove 21 is filled with water-swelling rubber 31 and a water-swelling filler material 32. Further a hardenable filler material 33 is filled in inner peripheries of the filled water-swelling rubber 31 and the water-swelling filler material 32. The groove 21 is formed by a traveling-type processing machine guided by a rail temporarily placed on the inner periphery of the structure such as the pipes 10, 11. COPYRIGHT: (C)2006,JPO&NCIPI
