CONSTRUCTION JOINT PART CONSTRUCTION METHOD FOR UNDERGROUND WALL, CONSTRUCTION JOINT FORMATION TOOL AND REINFORCEMENT CAGE
To provide a construction joint part construction method for underground walls that are applied for efficiently constructing the underground walls, to provide a construction joint formation tool, and to provide a reinforced cage.SOLUTION: A construction joint formation part 25 which has a corrugated steel plate 27 for mutually joining a subsequent panel 40 formed after a preceding panel 30 of an underground continuous wall 10 and the preceding panel 30 and a space holding member 28 for covering one end part side of the corrugated steel plate 27 is arranged in a preceding drilling groove ET1, and then, concrete is placed inside the preceding drilling groove ET1. By drilling the subsequent panel 40 side of the concrete of the formed preceding panel 30 and by cutting a portion of the subsequent panel 40 side of the space holding member 28, the subsequent panel 40 side of the corrugated steel plate 27 is exposed. After arranging a reinforced cage 20 of the subsequent panel 40 inside a subsequent drilling groove ET2, concrete is placed inside the subsequent drilling groove ET2.SELECTED DRAWING: Figure 1
【課題】地中壁を効率的に施工するための地中壁の打継部施工方法、打継形成具及び鉄筋籠を提供する。【解決手段】地中連続壁10の先行パネル30の後に形成する後行パネル40と先行パネル30とを互いに接合する波形鋼板27と、この波形鋼板27の一端部側を覆う空間保持部材28とを有した打継形成部25を、先行掘削溝ET1内部に配置した後、先行掘削溝ET1の内部をコンクリートで打設する。形成された先行パネル30のコンクリートの後行パネル40側を削るとともに、空間保持部材28の後行パネル40側の一部を切断することにより、波形鋼板27の後行パネル40側を露出させる。後行掘削溝ET2の内部に後行パネル40の鉄筋籠20を配置した後、後行掘削溝ET2の内部をコンクリートで打設する。【選択図】図1
