INSTALLATION METHOD FOR CORE MATERIAL
To provide an installation method for core material allowing the core material to be efficiently installed in a removed space of an underground obstacle.SOLUTION: An installation method for core material to install the core material in a removed space of an underground obstacle comprises: an obstacle removal process removing the underground obstacle embedded in a caisson after cutting the underground obstacle with a tip bit of the caisson pressed in the underground; a mouth pipe forming process pulling up the caisson from an underground hole formed in a removed space of the underground obstacle and leaving a tip side of the caisson as a mouth pipe in the underground hole; and a core material installation process placing a core material guide on a head part of the mouth pipe to install the core member in the underground hole by using a core material guide.SELECTED DRAWING: Figure 6
【課題】地中障害物の撤去跡に、効率よく芯材を建込むことである。【解決手段】地中障害物の撤去跡に芯材を建込むための、芯材の建込み方法であって、地中に圧入したケーシングの先端ビットで前記地中障害物を切削したのち、前記ケーシング内に取り込んだ前記地中障害物を撤去する障害物撤去工程と、前記地中障害物の撤去跡に形成された地中孔から前記ケーシングを引き上げ、該ケーシングの先端側を前記地中孔の口元管として残置する口元管形成工程と、前記口元管の頭部に芯材ガイドを設置し、該芯材ガイドを用いて前記地中孔に芯材を建込む芯材建込み工程と、を備える。【選択図】図６
