COLLAPSE PREVENTION PIPE, AND LOADING TEST METHOD
PROBLEM TO BE SOLVED: To provide a collapse prevention pipe for an excavated hole to be used suitably in a flat plate loading test method, the collapse prevention pipe being installed in a small installation space and curtailing time for setting up a test device.SOLUTION: A collapse prevention pipe 72s for an excavated hole is inserted into at least a part of a hole excavated into a ground, and forms a wall surface of the excavated hole 71. A loading test device includes a device body 2b having a fixing part to be frictionally fixed at a prescribed position in the excavated hole, a loading jack 48 disposed to be expandable/contractable on the device body 2b and having a loading rod 49 for applying a prescribed load on a hole bottom of the excavated hole 71, and measurement means 30 for measuring a position of the loading rod. The collapse prevention pipe 72s for an excavated hole supports the loading test device by bringing the fixing part of the loading test device into contact with an inner wall of the pipe separably, and includes a movement restricting member 75a disposed on an outer surface of the pipe, to extend outward.SELECTED DRAWING: Figure 12
【課題】設置スペースが小さくて済み、試験のための装置のセッティング時間を短縮することができる平板載荷試験法に好適に使用される削孔崩落防止パイプを提供する。【解決手段】削孔崩落防止パイプ72sは、地盤を掘削した掘削孔内の少なくとも一部に挿入され前記掘削孔71の壁面を形成し、前記掘削孔内の所定位置に摩擦固定可能な固定部を有する装置本体2bと、前記装置本体2bに対し伸縮可能に構成され、前記掘削孔71の孔底に所定の荷重を負荷する載荷ロッド49を有する載荷ジャッキ48と、前記載荷ロッドの位置を測定する計測手段30とを有する載荷試験装置の前記固定部が接離自在に内壁に当接することで前記載荷試験装置を支持する削孔崩落防止パイプ72sであって、周囲に張り出すように外表面に設けられた移動規制部材75aを備える。【選択図】図12
