GROUND SURVEY DEVICE, INSTRUMENT FOR GROUND SURVEY DEVICE, AND METHODS USING THESE
To propose a ground survey device that can conduct ground surveys with good workability and low cost.SOLUTION: A ground survey device of the present invention includes an inner body 2 and a fixed body K1. The fixed body K1 comprises: a plurality of anchor portions 13 which are arranged at intervals in the circumferential direction and are expanded outward in a radial direction to fix the fixed body K1 to a boring hole 104; and a fixed body female screw portion 11 which attaches the inner body 2. The inner body 2 has: an inner body male screw portion 7 screwed into the fixed body female screw portion 11; and an inner body female screw portion 6 which is opposite to the inner body male screw portion 7 and has a central axis common to the central axis of the inner body male screw portion 7.SELECTED DRAWING: Figure 1
【課題】地盤調査を作業性よく安価に行うことが可能な地盤調査装置を提案する。【解決手段】本発明の地盤調査装置は、内側体２と固定体Ｋ１とを備え、固定体Ｋ１は、周方向に間隔をあけて複数配置され、径方向外側に向けて押し広げられて固定体Ｋ１をボーリング孔１０４に固定させるアンカー部１３と、内側体２を取り付けるための固定体雌ねじ部１１と、を有し、内側体２は、固定体雌ねじ部１１に螺合する内側体雄ねじ部７と、内側体雄ねじ部７とは逆回りであって内側体雄ねじ部７の中心軸と共通する中心軸を有する内側体雌ねじ部６と、を有する。【選択図】図１
