COMPOSITE PILE, AND CONSTRUCTION METHOD OF COMPOSITE PILE
To provide a composite pile which can be efficiently constructed without overload applied to a boring machine drilling the ground, and to provide a construction method of the composite pile.SOLUTION: A composite pile 1 has a cylindrical shape constituted by a large pile portion 10 vertically constructed in a ground 100 and having a large diameter and a small pile portion 20 having a smaller diameter than that of the large pile portion 10 and extending downwardly from a lower face of the large pile portion 10, and is constituted by stabilized soil in which soil and soil stabilizer are mixed. The pile is constructed by: a hole drilling step of forming a large pile hole 31 and a small pile hole 32 in the ground 100; and a pile forming step of mixing the soil and the soil stabilizer and injecting into an inside of a pile hole 30 to construct the large pile portion 10 and the small pile portion 20. The soil used in the pile forming step is generated soil generated in the hole drilling step.SELECTED DRAWING: Figure 1
【課題】地盤を削孔するボーリング機に過負荷がかかることなく、効率的に構築できる合成杭及び合成杭の構築方法を提供することを目的とする。【解決手段】地盤１００に垂直方向に構築される直径が大きな大型杭部１０と、大型杭部１０より小さい直径を有するとともに、大型杭部１０の下面から下方に延長される小型杭部２０とで構成される円筒形状であり、土と土質安定材とを混合した安定処理土で構成する合成杭１を、大杭孔３１及び小杭孔３２を地盤１００に形成する削孔工程と、土及び土質安定材を杭孔３０の内部に混合注入して大型杭部１０及び小型杭部２０を構築する杭形成工程とを行って構築し、杭形成工程で用いる土が、削孔工程で発生する発生土である。【選択図】図１
