EROSION PREVENTION SHEET FOR EMBANKMENT
PROBLEM TO BE SOLVED: To provide an erosion prevention sheet that securely prevents overflow water from flowing down a back slope of an embankment.SOLUTION: An erosion prevention sheet 1 for an embankment comprises: a sheet 2 made of an impermeable material; and flexible dams 3, 3 disposed in parallel with an interval on an upper surface of the sheet 2. The dams 3, 3 are opposed to each other. The dams 3, 3 and the sheet 2 extending therebetween form a water passage with a concave cross section. The erosion prevention sheet 1 is disposed on an embankment 21 such that the sheet 1 covers an area including an upper part 22 and a back slope 23 of the embankment 21 and a ground 24 inside the embankment, and the transverse direction of the dam 3 is substantially orthogonal to a dam body axis of the embankment 21.
【課題】越流水が堤防の裏法面を流下するのを確実に防止する侵食防止シートを提供する。【解決手段】堤防の侵食防止シート１は、不透水性材料で構成されたシート体２とシート体２の上面に互いに離間するように２列に並設された可撓性の堰堤３，３とで構成してある。堰堤３，３は、互いに対向するように配置してあり、堰堤３，３の間に延びるシート体２とともに、横断面が凹部状の水路を形成するようになっている。侵食防止シート１を堤防２１に設置するにあたっては、堤防２１の上面２２から裏法面２３を経て堤内側地盤面２４に至る範囲が覆われるようにかつ堰堤３の列方向が堤防２１の堤体軸線とほぼ直交するように敷設する。【選択図】図２
