SAND PREVENTIVE SHEET-LAYING STRUCTURE
To disperse a tensile force acting on a sand preventive sheet which is laid on a slope face of a rubble mound mounted with a harbor revetment caisson.SOLUTION: A sand preventive sheet-laying structure includes a net-like body base 15 which has an upper end fixed to a revetment caisson 2 and is formed of a wire mesh laid on so as to cover a rubble surface from a top end to a slope face of a rubble mound 3, and a sand preventive sheet 11 which is connected to the net-like body base 15 so as to be brought into surface contact with each other. The net-like body base 15 and the sand preventive sheet 11 are integrally connected to each other through a plurality of connection means 12 that are vertically mounted on the surface of the sand preventive sheet 11 in an elongation-deformable manner. When a landfill load acts on a sand preventive sheet-laying structure 10 and a wire in a partial portion of the wire mesh reaches a strength limitation or elongation limitation, the landfill load is burdened by only the sand preventive sheet 11 where the vicinity of the wire in the partial portion is connected to the wire.SELECTED DRAWING: Figure 6
【課題】 港湾護岸ケーソンが載置される捨て石マウンドの法面に敷設される防砂シートに作用する引張力の分散を図る。【解決手段】 護岸ケーソン２に上端部が固定され、捨て石マウンド３の天端から法面にかけて捨て石面を覆うように敷設される金網からなる網状体ベース１５と、網状体ベース１５に面接触して連結される防砂シート１１とを備える。網状体ベース１５と防砂シート１１とは、防砂シート１１の表面に縦横に取り付けられた複数の連結手段１２を介して一体的に伸び変形可能に連結される。防砂シート敷設構造１０に埋立荷重が作用し、金網の一部の箇所の線材が強度限界あるいは伸び限界に達した際、一部の箇所の線材の近傍が線材と連結されていた防砂シート１１のみで埋立荷重が負担される。【選択図】図６
