TEMPORARY COFFERDAM BODY, AND FORMING METHOD FOR CLOSED TYPE TEMPORARY COFFERDAM BODY
To provide a temporary cofferdam body and a forming method for a closed type temporary cofferdam body that enable both complete and partial closure of the surroundings of a weir and transmit an axial force caused by water pressure when closed and internally drained, in the circumferential direction.SOLUTION: In temporary cofferdam bodies 100, 200 constructed around a weir pillar 10, an upstream box body 20 and a downstream box body 30 are arranged around the weir pillar 10, there is a first gap 10a at a lateral side of the weir pillar 10, and the upstream box body 20 and the downstream box body 30 respectively comprise an upstream wall body 40 and a downstream wall body 50. By closing the wall bodies 40, 50, a closed type temporary cofferdam body 200 is formed. When the first gap 10a is closed, ends 42, 52 of the wall bodies 40, 50 are connected by a continuing member 80, and an axial force N caused by water pressure P acting on the temporary cofferdam body 200 by draining water between the temporary cofferdam body 200 and the weir pillar 10 is transmitted in the circumferential direction of the temporary cofferdam body 200 via the continuing member 80.SELECTED DRAWING: Figure 8B
【課題】堰の周囲の完全閉塞と一部閉塞を可能にし、閉合して内部の水抜きをした際に作用する水圧に起因する軸力を周方向へ伝達可能にする、仮締切り体と、閉塞型の仮締切り体の形成方法を提供する。【解決手段】堰柱１０の周囲に構築される仮締切り体１００，２００であり、堰柱１０の周囲には上流側箱体２０と下流側箱体３０が配設され、堰柱１０の側方には第１隙間１０ａがあり、上流側箱体２０と下流側箱体３０はそれぞれ上流側壁体４０と下流側壁体５０を備えており、壁体４０，５０を閉合することにより、閉塞型の仮締切り体２００が形成され、第１隙間１０ａが閉塞された際に、壁体４０，５０の端部４２，５２同士が連続部材８０により連続され、仮締切り体２００と堰柱１０の間の水が抜かれることにより仮締切り体２００に作用する水圧Ｐに起因する軸力Ｎが、連続部材８０を介して仮締切り体２００の周方向に伝達される。【選択図】図８Ｂ
