BAMBOO DRAIN MATERIAL AND LIQUEFACTION COUNTERMEASURE CONSTRUCTION METHOD
To provide a drain material capable of suppressing liquefaction of ground relatively simply and inexpensively, and a liquefaction countermeasure construction method.SOLUTION: In a liquefaction countermeasure construction method, a bamboo drain material 1 is buried into a depth reaching at least liquefaction layers G2, G4. In this case, a plurality of bamboo drain materials 1 in a bundled state (bamboo bundle 3) are buried into the ground. Draining holes are formed penetrating through the bamboo drain materials 1 at parts facing the liquefaction layers G2, G4, and a through-hole is formed at each node of the bamboo drain materials 1. Granular fillers are filled in the bamboo drain materials 1. Further, the bamboo drain materials 1 are formed in a predetermined length by connecting a plurality of drain components made of bamboo stems in the axial direction.SELECTED DRAWING: Figure 1
【課題】比較的簡易かつ安価に地盤の液状化を抑制することを可能としたドレーン材、並びに液状化対策工法を提案する。【解決手段】竹製ドレーン材１を少なくとも液状化層Ｇ２，Ｇ４に到達する深さまで埋め込む液状化対策工法である。このとき、複数の竹製ドレーン材１を束ねた状態（竹束３）で地中に埋め込む。また、竹製ドレーン材１には、液状化層Ｇ２，Ｇ４に面する部分に、竹製ドレーン材１の内外を貫く排水孔を形成し、竹製ドレーン材１の各節に貫通孔を形成する。また、竹製ドレーン材１内には、粒状の充填材を充填する。さらに、竹製ドレーン材１は、竹の幹からなる複数のドレーン構成材を軸方向に連結して所定の長さに形成する。【選択図】図１
