WATER CUT-OFF STRUCTURE OF BOX BODY CONSTITUTING TEMPORARY COFFERDAM BODY AND BOTTOM PLATE, AND WATER CUT-OFF STRUCTURE OF BOX BODY CONSTITUTING TEMPORARY COFFERDAM BODY AND WEIR COLUMN
To provide a water cut-off structure of a box body constituting a temporary cofferdam body and a bottom plate, having high water cut-off property between the box body and the bottom plate, and a water cut-off structure of a box body constituting a temporary cofferdam body and a weir column, having high water cut-off property between a side face of the weir column and the box body.SOLUTION: In a weir having a weir column and a main gate that extends to a side part of the weir column and can be freely ascended and descended, in a water cut-off structure of a box body that constitutes a temporary cofferdam body constructed in the periphery of the weir column and is arranged in the periphery of the weir column and a bottom plate, a leg part steel plate 20d is fixed to a side part of a side face of a leg part of the box body 20 grounded to a bottom plate 15 below the weir column through a first gap holding bolt 20h with a gap between the side face of the box body 20 and the leg part steel plate, a first cut-off material 20e is stored in the gap, and its tip is brought into contact with the bottom plate 15.SELECTED DRAWING: Figure 12
【課題】箱体と底盤との間における高い止水性を備えた、仮締切り体を構成する箱体と底盤の止水構造と、堰柱の側面と箱体との間における高い止水性を備えた、仮締切り体を構成する箱体と堰柱の止水構造を提供する。【解決手段】堰柱と、堰柱の側方に延設する昇降自在な本設ゲートと、を有する堰において、堰柱の周囲に構築される仮締切り体を構成し、堰柱の周囲に配設される箱体と底盤の止水構造であって、堰柱の下方にある底盤１５に着底された、箱体２０の脚部の側面の側方には、脚部鋼板２０ｄが、箱体２０の側面との間に隙間を置いて第１隙間保持ボルト２０ｈを介して固定され、隙間に第１止水材２０ｅが収容されてその先端が底盤１５に接している。【選択図】図１２
