SOIL DRAW-OUT PREVENTION STRUCTURE AND SOIL DRAW-OUT PREVENTION METHOD FOR REVETMENT STRUCTURE
PROBLEM TO BE SOLVED: To provide a soil draw-out prevention structure and a soil draw-out prevention method for a revetment structure capable of being constructed without the need for a diving operation in a deepwater area and capable of being easily repaired by virtue of its solidness.SOLUTION: A back-filling stone part 5 is provided on the backside of a front structure 4 that is installed on a rubble-mound 3. A sediment outflow prevention layer 7 is provided between the back-filling stone part 5 and a reclaimed part 6. The sediment outflow prevention layer 7 comprises a solidified layer part 10 that is made of solidified soil ranging from a water bottom part 1 to a desired height H below a water surface, and a sand prevention sheet 11 for covering a part above the desired height H of the back-filling stone part 5.SELECTED DRAWING: Figure 1
【課題】大水深部分での潜水作業を必要とせずに構築でき、頑丈で修繕も容易な護岸構造物の吸出し防止構造及び吸出し防止工法の提供。【解決手段】捨石マウンド３上に設置された前方構造体４の背面側に裏込め石部５を備え、裏込め石部５と埋め立て部６との間に土砂流出防止層７を備え、 土砂流出防止層７は、水底部１から水面下の所望の高さＨにまで至る固化処理土からなる固化処理層部１０と、裏込め石部５の所望の高さＨより上の部分を覆う防砂シート１１とを備えている。【選択図】図１
