LIQUEFACTION COUNTERMEASURE STRUCTURE IN SITE
PROBLEM TO BE SOLVED: To provide a liquefaction countermeasure technique having the sufficient pore water pressure relieving effect, in the inexpensive and construction-easy liquefaction countermeasure technique suitable for a site of a structure such as a medium-small scale building.SOLUTION: In a structure for constructing a structure on the upper side of a resin block layer 4 provided in a recessed part formed by digging down a site 1, the resin block layer 4 is formed of a plurality of horizontally juxtaposed resin blocks 5. Each of the resin blocks 5 is a resin (except for styrene foam) structural member for supporting the structure while forming a pore water pressure relieving space S on the lower side of the structure, and has an opening so that water can enter the inside. The resin block layer 4 is covered in the whole with a sand shield water permeable sheet of permeating the water while cutting off sand of the ground.SELECTED DRAWING: Figure 1
【課題】中小規模の建築物等の構築物の敷地に適した安価で施工が容易な液状化対策技術であって、十分な間隙水圧緩和の効果のある液状化対策技術を提供する。【解決手段】敷地1を掘り下げて形成された凹部に設けられた樹脂ブロック層4の上側に構築物が施工された構造であり、樹脂ブロック層4は水平に並べられた複数の樹脂ブロック5で形成されている。各樹脂ブロック5は、構築物の下側に間隙水圧緩和空間Sを形成しつつ構築物を支える樹脂(発泡スチロールを除く)製の構造部材であり、内部に水が進入できるよう開口を有する。樹脂ブロック層4は、地盤の砂を遮断しつつ水を透過させる遮砂透水シートにより全体が覆われている。【選択図】図1
