GROUND IMPROVEMENT PILE AND GROUND IMPROVEMENT METHOD
PROBLEM TO BE SOLVED: To provide a ground improvement pile and a ground improvement method that promote compaction of a fine-grained soil ground, and dissipate excess pore water pressure in a coarse-grained soil ground and perform compaction of the coarse-grained soil ground, while attempting to reduce construction costs and curtail a construction period.SOLUTION: The present invention relates to a ground improvement pile 1 installed in a ground 8. The ground improvement pile 1 according to an embodiment of the present invention includes a pile side surface 2 of a roughly tapered form that inclines from an end 1a to the other end 1b, and a pile interior 3 of a roughly hollow form surrounded by the pile side surface 2. One or a plurality of open holes 5 is formed on the pile side surface 2 that penetrates to the pile interior 3.SELECTED DRAWING: Figure 2
【課題】施工コストの低減、施工期間の短期化を図りながら、細粒土地盤の圧密促進を実施して、また、粗粒土地盤の過剰間隙水圧の消散と粗粒土地盤の締固めとを実施することのできる地盤改良杭及び地盤改良工法を提供する。【解決手段】地盤８内に設けられる地盤改良杭１に関する。本発明を適用した地盤改良杭１は、軸芯方向Ｙで一方の端部１ａから他方の端部１ｂまで傾斜させて略テーパ状に形成された杭側面部２と、杭側面部２に取り囲まれて略中空状に形成された杭内部３とを備える。杭側面部２は、杭内部３まで貫通するように１又は複数の貫通孔５が形成される。【選択図】図２
