間隙水圧測定アセンブリ及びその設置方法
Abstract:
【課題】ドレーン材打設装置を用いて地中に配置可能な間隙水圧測定アセンブリと、間隙水圧測定アセンブリを設置する方法とを提供する。 【解決手段】間隙水圧測定アセンブリ1は、ドレーン材打設装置が備えるケーシングを用いて地中に配置される。間隙水圧測定アセンブリ1は、平板部21と、平板部21の上面から上方に延びるロッド部22とを有するアンカー部材2と、通水材で形成されており、平板部21の上面に取り付けられてロッド部22を収容するように配置された筒状部材3と、ロッド部22に結合している間隙水圧計4と、平板部21の上面から上方へと、間隙水圧計4が埋まるように筒状部材3内に詰められたフィルター材5と、フィルター材5を封止するように筒状部材3内に詰められたシール材6とを備えている。 【選択図】図2
Abstract(English):

To provide a pore water pressure measurement assembly which can be arranged in the ground using a drain material installation device, and a method for installing the pore water pressure measurement assembly.SOLUTION: A pore water pressure measurement assembly 1 is arranged in the ground using a casing provided on a drain material installation device. The pore water pressure measurement assembly 1 includes: an anchor member 2 having a flat plate part 21 and a rod part 22 extending upward from the upper surface of the flat plate part 21; a cylindrical member 3 which is formed of a water passing material, is mounted on the upper surface of the flat plate part 21 and is arranged so as to store the rod part 22; a pore water pressure gage 4 which is coupled to the rod part 22; a filter material 5 which is made to fill the cylindrical member 3 from the upper surface of the flat plate part 21 to the upper part so as to fill the pore water pressure gage 4; and a seal material 6 which is made to fill the cylindrical member 3 so as to seal the filter material 5.SELECTED DRAWING: Figure 2
