BOX BODY CONSTITUTING TEMPORARY COFFERDAM BODY AND DRAFT ADJUSTMENT METHOD OF THE SAME
To provide a box body constituting a temporary cofferdam body capable of adjusting draft in a desired manner, and a draft adjustment method of the same.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, a box body constitutes a temporary cofferdam body constructed in the periphery of the weir column and is arranged in the periphery of the weir column. The box body includes a hollow part 20a, a feeding/discharging pipe 21c communicating the hollow part 20a and external water W, a feeding/discharging valve 21b, a feeding/exhausting pipe 21e, a feeding/exhausting valve 21d and a pressure air supply part 21f for supplying pressure air to the feeding/exhausting pipe 21e, and the box body is floated and sunk by opening/closing at least one of the feeding/discharging valve 21b and the feeding/exhausting valve 21d.SELECTED DRAWING: Figure 6B
【課題】喫水を所望に調整可能な仮締切り体を構成する箱体とその喫水調整方法を提供する。【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、箱体であって、箱体は、中空部２０ａと、中空部２０ａと外部水Ｗを連通する注排水管２１ｃと、注排水バルブ２１ｂと、給排気管２１ｅと、給排気バルブ２１ｄと、給排気管２１ｅに圧力空気を供給する圧力空気供給部２１ｆとを備え、注排水バルブ２１ｂと給排気バルブ２１ｄの少なくとも一方の開閉により、箱体が浮沈されるようになっている。【選択図】図６Ｂ
