DRAINAGE MATERIAL INSTALLATION METHOD FOR NATURAL GROUND
PROBLEM TO BE SOLVED: To provide a drainage material installation method for natural ground, which does not damage the following filter even in the case of a drainage material having an outer periphery provided with the filter for preventing inflow of sediment, and which enables execution of work for installation of the drainage material without any vibration or noise and without earth removal.SOLUTION: In a drainage material 5, an outer periphery of a synthetic resin drain pipe 6 having a large number of water-permeable holes formed in its peripheral wall is covered with a nonwoven fabric filter 7, and its top surface is held by a geotextile net 8. A sharp-edged excavation head 9 is installed. The drainage material 5 is advanced into natural ground while the excavation head is rotated by a rotating shaft 10 for excavation, which is inserted into the drainage material 5.SELECTED DRAWING: Figure 1
【課題】外周に土砂流入防止のフィルタを有する排水材であっても該フィルタを傷つけることなく、無振動、無騒音、無排土で排水材の設置の施工ができる地山の排水材設置工法を提供する。【解決手段】排水材５は、多数の透水孔をその周壁に形成した合成樹脂製排水パイプ６の外周を不織布フィルタ７で覆い、その上からジオテキスタイルネット８で押えたものであり、尖り状の掘削ヘッド９を設置し、排水材５の内部に挿通する掘削回転軸１０で掘削ヘッドを回転させながら排水材５を地山に掘進させる。【選択図】 図１
