DRAIN MATERIAL FOR LIQUEFACTION COUNTERMEASURE, LIQUEFACTION COUNTERMEASURE GROUND STRUCTURE AND CONSTRUCTION METHOD OF LIQUEFACTION COUNTERMEASURE GROUND STRUCTURE
To provide a liquefaction countermeasure ground structure which carries out a liquefaction countermeasure without reducing the rigidity of the ground and has excellent workability.SOLUTION: Provided is a liquefaction countermeasure ground structure in which a plurality of drain materials 1, 1 are embedded in the ground G at lateral intervals for a liquefaction countermeasure. The drain material 1 includes a perforated tube 2 placed in the center, a drainage sheet 3 formed of highly rigid drainage materials wrapped around the perforated pipe 2, and a cylindrical outer peripheral filter 4 arranged on the outer circumference of the drainage sheet 3 to be wound.SELECTED DRAWING: Figure 1
【課題】地盤の剛性を低下させることなく液状化対策が行えるうえに、施工性に優れた液状化対策地盤構造を提供する。【解決手段】液状化対策のために横方向に間隔を置いて地盤Ｇに複数のドレーン材１，１が埋設された液状化対策地盤構造である。ドレーン材１は、中心に配置される有孔管２と、有孔管２の周囲に巻き付けられる高剛性排水材によって形成された排水シート３と、巻き付けられる排水シート３の外周に配置される円筒状の外周フィルタ４とを備えている。【選択図】図１
