TEMPORARY COFFERDAM, AND CONSTRUCTION METHOD OF CLOSED TEMPORARY COFFERDAM
To provide a temporary cofferdam capable of achieving complete closing and partial closing a periphery of a weir, and a construction method of a closed temporary cofferdam included in the temporary cofferdam.SOLUTION: In a weir that has a weir column 10 and a main gate that extends sideward of the weir column 10 and is capable of being lifted up and lowered down, a temporary cofferdam 200 is constructed in a periphery of the weir column 10. At an upstream side and a downstream side of the weir column 10, an upstream box body 20 and a downstream box body 30 are arranged respectively. In the side of the weir 10 between box bodies 20, 30, there are first spaces. Each of the upstream box body 20 and the downstream box body 30 includes an upstream wall 40 and a downstream wall 50. When the walls 40, 50 are closed, the first space is closed, and a closed temporary cofferdam 200 is formed by the box bodies 20, 30 and the walls 40, 50.SELECTED DRAWING: Figure 3
【課題】堰の周囲の完全閉塞と一部閉塞を可能にした仮締切り体と、この仮締切り体に含まれる閉塞型の仮締切り体の構築方法を提供する。【解決手段】堰柱１０と、堰柱１０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１０の周囲に構築される仮締切り体２００であって、堰柱１０の周囲の上流側と下流側にはそれぞれ、上流側箱体２０と下流側箱体３０が配設され、双方の箱体２０，３０の間の堰柱１０の側方には第１隙間があり、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、第１隙間が閉塞されて、双方の箱体２０，３０と双方の壁体４０，５０とにより、閉塞型の仮締切り体２００が形成される。【選択図】図３
