SAND PREVENTIVE SHEET LAYING STRUCTURE
To prevent curling of a sand preventive sheet laid on a slope surface of a backfill part of a revetment caisson.SOLUTION: A sand preventive sheet laying structure incudes a sand preventive sheet 11 laid on a slope face 5b of a backfill part 5 of a revetment caisson 1 installed on a rubble mound, and a lattice-like net 15 which is wired in longitudinal and lateral directions with a predetermined mesh size, is fixed to the upper surface of the sand preventive sheet 11, has a plurality of wire engagement hooks 20 mounted on one end in a slope face direction at a predetermined interval, and stabilizes the sand preventive sheet 11 on the slope face 5b, wherein the sand preventive sheet 11 on the upper side where the wire engagement hooks 20 are mounted is laid while securing an overlapping part having a predetermined width in the longitudinal direction of the slope face 5b, so as to cover the end of the lattice-like net 15 on the sand preventive sheet 11 on the lower side that is already laid on the slope face 5b. When floating force acts on the sand preventive sheet 11 from the slope face 5b, the wire engagement hooks 20 are engaged with the end wires of the lattice-like net 15 on the sand preventive sheet on the lower side, thereby preventing the floating of the sand preventive sheet.SELECTED DRAWING: Figure 1
【課題】 護岸ケーソンの裏込め部法面に敷設される防砂シートのめくれ防止を図る。【解決手段】 捨て石マウンド上に設置された護岸ケーソン１の裏込め部５の法面５ｂに敷設される防砂シート１１と、所定の目合いで縦横方向に配線され、防砂シート１１の上面に固定され、法面方向の一方の端部に所定間隔をあけて複数個のワイヤ係止フック２０が取り付けられ、防砂シート１１を法面５ｂ上に安定させる格子状ネット１５とを備え、防砂シート１１は、すでに法面上５ｂに敷設された下側の防砂シート１１上の格子状ネット１５の端部を覆うように、ワイヤ係止フック２０が取り付けれた上側の防砂シート１１が法面５ｂの長手方向に沿って所定幅の重なり部を確保して敷設され、法面５ｂから浮き上がり力が作用した際に、ワイヤ係止フック２０が下側の防砂シート上の格子状ネット１５の端部ワイヤに係止して防砂シート１１の浮き上がりが防止される。【選択図】 図１
