CORE MATERIAL BUILDING-IN METHOD AND CORE MATERIAL BUILDING-IN DEVICE
To provide a core material building-in method with which core material building-in work can be performed efficiently even if joint core materials constituted by joining a single split core material or multiple split core materials are heavy in places subject to height restrictions, and a core material building-in device using the method.SOLUTION: In a core material building-in method in which, when building core materials into drilling holes 2 formed in a ground 1 of a place (site) G where a height restriction H is applied, a core material of a predetermined length which should be built in the drilling holes 2 is split into pieces and split core materials 3a thus split are sequentially joined and built in, the single split core material 3a or joint core materials 3X are built into the drilling holes 2 by being hung down by using a core material building-in device 45 constituted by providing hanging means 5 capable of hanging the joint core materials 3X constituted by joining the single split core material 3a or the multiple split core materials 3a in a frame 4 installed on the ground 1 around openings of the drilling holes 2.SELECTED DRAWING: Figure 1
【課題】高さ制限を受ける場所において、単一の分割芯材又は複数の分割芯材が継がれて構成される継ぎ芯材の重量が大きい場合でも、芯材建込作業を効率的に行える芯材建込方法、及び、当該方法に使用する芯材建込装置を提供する。【解決手段】高さ制限Ｈを受ける場所（現場）Ｇの地盤１に形成した掘削孔２内に芯材を建て込む際に、掘削孔２内に建て込まれるべき所定の長さの芯材を複数に分割し、当該分割した分割芯材３ａを順次継ぎ足して建て込む芯材建込方法において、掘削孔２の孔口の周囲の地盤１上に設置した架構４に、単一の分割芯材３ａ又は複数の分割芯材３ａが継がれて構成される継ぎ芯材３Ｘを吊ることが可能な吊り手段５を設けて構成された芯材建込装置４５を用いて、当該単一の分割芯材３ａ又は当該継ぎ芯材３Ｘを吊り降ろすことにより掘削孔２内に建て込むようにした。【選択図】図１
