ANTICORROSIVE LINING, ANTICORROSIVE LINING SEGMENT, AND THEIR MANUFACTURE

摘要

PROBLEM TO BE SOLVED: To provide an anticorrosive lining, an anticorrosive lining segment, and their manufacturing method capable of omitting secondary lining in the construction of a sewage pipe line and preventing an anticorrosive layer protecting from the corrosion of primary lining due to sewage from being peeled off and destructed due to water pressure of underground water. ;SOLUTION: In an anticorrosive lining segment 1, an anticorrosive layer 2 preventing the corrosion of the inside of the segment due to sewage in a tunnel is provided on an inner peripheral face thereof. It is provided with a water penetration layer 3 provided on an outer peripheral side from the anticorrosive layer 2 and a water drain means for draining water from the water penetration layer 3 to the inside of the tunnel or an end part of the tunnel. The water penetration layer 3 is provided between both end faces in the longitudinal direction of the tunnel of the anticorrosive lining segment 1 or a check valve is provided to constitute the above-mentioned water drain means. At least a part of the water penetration layer 3 is formed by a porous member. The porous member forming the water penetration layer 3 is formed by aggregate having a specified particle diameter and synthetic resin such as epoxy resin.;COPYRIGHT: (C)1999,JPO
