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
