Water barrier structure of Revetment concrete and repairing method of Revetment concrete

摘要

PROBLEM TO BE SOLVED: To provide a water shut-off structure for concrete revetment and a repair construction method for concrete revetment, capable of significantly improving the water shut-off performance with a double water shut-off structure comprising: a water shut-off layer on an undersurface of an existing concrete revetment; and an aquiclude installed underneath the water shut-off layer.;SOLUTION: The present invention relates to a water shut-off structure 1 for concrete revetment that prevents water leakage into the sea from an existing concrete revetment 5. The water shut-off structure 1 for concrete revetment that applies the present invention includes a water shut-off layer 2 that blocks water leakage from the concrete revetment 5 and an aquiclude 3 installed underneath the concrete revetment 5. The water shut-off layer 2 is installed at least on an undersurface 5a of the existing concrete revetment 5, while the aquiclude 3 is installed at a gap part 4 formed continuously with and underneath the water shut-off layer 2 installed on the undersurface 5a of the existing concrete revetment 5.;COPYRIGHT: (C)2015,JPO&INPIT
