ACCRETION REMOVAL TOOL OF CORE MATERIAL OF UNDERGROUND CONTINUOUS WALL
To provide an accretion removal tool of a core material of a continuous wall which removes an accretion attached to a male joint, prevents a foreign matter from entering into a female joint, facilitates construction, and does not require a special device for construction.SOLUTION: An accretion removal tool 5 for removing an accretion attached to a core material 2 of an underground continuous wall used when it is build by connecting a female joint 30 of a core material 3 to a male joint 20 of a core material 2 of a built underground continuous wall, includes a body part 50 having an upper surface 50a in contact with a lower end opening 30a of an internal space part 301 of the male joint 30, a reinforcement material 7 embedded in the body part 50, and a notch 51 which surrounds an extension piece 200 and an anti-slip piece 201 of the male joint 20, and is engaged with the male joint 20 so as to be slidable in the longitudinal direction of the male joint 20, wherein the outer shape of the upper face 50a is larger than the inner shape of the lower end opening 30a other than the notch 51.SELECTED DRAWING: Figure 2
【課題】雄継手に付着している付着物を除去するとともに雌継手内部に異物が侵入するのを防ぎ、施工が容易で特殊な施工用機器を必要としない連続壁の芯材の付着物除去具を提供すること。【解決手段】既に建て込まれた地中連続壁の芯材２が有する雄継手２０に芯材３が有する雌継手３０を連結させて建て込まれる際に用いられる地中連続壁の芯材２に付着した付着物を除去する付着物除去具５で、雌継手３０の内空部３０１の下端開口部３０ａに当接する上面５０ａを有する本体部５０と、本体部５０に埋め込まれる補強材７と、雄継手２０の延出片２００と抜け止め片２０１を取り囲み、且つ、雄継手２０の長手方向に沿って摺動可能に係合させる切欠き部５１と、を備え、上面５０ａの外形は、切欠き部５１以外において下端開口部３０ａの内形より大きい。【選択図】図２
