BACK FILLING DEVICE OF DRILLING HOLE AND BACK FILLING METHOD OF DRILLING HOLE
To provide a back filling device of drilling hole capable of surely discharging a filler into a drilling hole from a container without using a coating material.SOLUTION: A back filling device 1 of a drilling hole which uses bentonite and/or a bentonite-based material mostly containing bentonite as a filler 3 and back-fills a drilling hole 2 includes: a cylindrical container 7 comprising a double pipe of an outer pipe 5 and an inner pipe 6; a bag material 12 whose end part is fixed to an inner surface above the outer pipe 5, and which has a bag-like storage part 16 formed by being folded back from an opening 14 on a lower side of the inner pipe 6 toward an inner surface of an apex part 15 on an upper side; an openable/closable lid 11 arranged on a lower end of the outer pipe 5; and a filler discharge mechanism 17 which allows downward relative displacement of the inner pipe 6 with respect to the outer pipe 5 according to the opening of the lid 11 when the container 7 is conveyed to a predetermined position inside the drilling hole 2, and which allows the filler 3 filled in the bag-like storage part 16 to be discharged to the outside of the container 7.SELECTED DRAWING: Figure 4
【課題】コーティング材を用いないで充填材を容器から掘削孔内に確実に吐出できる掘削孔の埋め戻し装置を提供すること。【解決手段】充填材3として、ベントナイト及び/又はベントナイトを主として含むベントナイト系材料を用いて掘削孔2を埋め戻す掘削孔の埋め戻し装置であって、外管5と内管6との二重管からなる筒状の容器7と、外管5の上方の内面に端部が固定されるとともに、内管6の下方側の開口14から上方側の有頂部15内面に向けて折り返されて形成された袋状格納部16を有する袋材12と、外管5の下端に配置された開閉自在な蓋11と、容器7が掘削孔2内の所定位置まで搬送された際に蓋11の開放に伴って内管6の外管5に対する下方への相対変位を許容して、袋状格納部16に装填された充填材3を容器7の外部に吐出させる充填材吐出機構17と、を備える掘削孔の埋め戻し装置1。【選択図】図4
