PREVENTION STRUCTURE FOR OUTFLOW OF SHORE PROTECTING RECLAMATION SEDIMENT
To prevent, in a prevention structure for an outflow of shore protecting reclamation sediment, damage to a sand prevention sheet from the time of placement of the sand prevention sheet to even after the placement.SOLUTION: The present invention includes a caisson (3) defining a sea side (S) and a land side (L), an embedded stone layer part (4) that is formed by piling embedded stones (17) on the land side (L) of the caisson (3) and that has a sloping surface (4T), a sand prevention sheet (18) placed on the sloping surface (4T) of the embedded stone layer part (4), and a reclamation sediment layer part (6) formed by putting reclamation sediment (24) on the sand prevention sheet (18) on the land side (L) of the caisson (3). The present invention also includes net-like members (19-1, 19-2) for covering surfaces (18A, 18B) of the sand prevention sheet (18).SELECTED DRAWING: Figure 1
【課題】護岸埋立土砂流出防止構造において、防砂シートの敷設時から敷設後であっても、防砂シートの損傷を防止することにある。【解決手段】海側（Ｓ）と陸側（Ｌ）とを区画するケーソン（３）と、ケーソン（３）の陸側（Ｌ）で裏込石（１７）を積み上げて形成され且つ法面（４Ｔ）を有する裏込石層部（４）と、裏込石層部（４）の法面（４Ｔ）上に敷設される防砂シート（１８）と、ケーソン（３）の陸側（Ｌ）で防砂シート（１８）上に埋立土砂（２４）を投入して形成される埋立土砂層部（６）とを備えるとともに、防砂シート（１８）の面（１８Ａ・１８Ｂ）を覆うための網状部材（１９−１・１９−２）を備えている。【選択図】図１
