CRUSHED STONE PILE
PROBLEM TO BE SOLVED: To provide a crushed stone pile, which can function as a bearing pile thanks to a means to prevent the crushed stone pile from deforming due to a load from an object laid on the pile, and a forming method thereof.SOLUTION: A crushed stone pile is a columnar body 4, which is formed by placing crushed stones 3, cobble stones or concrete debris in a low strength pipe 1 such as a vinyl chloride pipe, a thin steel pipe or a drain pipe that is buried underground in advance. A circumference of the columnar body 4 is wrapped with the low strength pipe 1 in order to prevent deformation.SELECTED DRAWING: Figure 1
【課題】砕石杭（砕石パイル）に上載荷重に対する変形の発生を防止する工夫を施し、その結果、砕石杭（砕石パイル）に支持杭としての機能を持たせることができるようになる砕石杭およびその形成工法を提供する。【解決手段】地中に先行して埋設した塩化ビニル管や薄肉鋼管、もしくはドレーン管等の低強度管１内に砕石３または玉石もしくはコンクリートガラを投入して形成される柱状体４であり、該柱状体４の外周が変形防止としての低強度管１で包抱される。【選択図】 図１
