TEMPORARY COFFERDAM CONSTRUCTION METHOD AND TEMPORARY COFFERDAM BODY
To provide a temporary cofferdam construction method and a temporary cofferdam body which can construct a temporary cofferdam in a state where the going-upstream of seawater is shielded when a weir column of an estuary weir whose gate extends to the side of the weir column is maintained and repaired.SOLUTION: A temporary cofferdam construction method constructs a temporary cofferdam in the periphery of a weir column 1 in an estuary weir 10 having the weir column 1 and a gate 3 extending to the side of the weir column 1 includes: a step A of installing a temporary gate 20 provided in the gate 3 on the side of the weir column 1; a step B of installing a first divided box body 30 on one side in the periphery of the weir column 1; and a step C of opening the gate 3, installing a second divided box body 40 on the other side in the periphery of the weir column 1, and connecting the first divided box body 30 and the second divided box body 40 to form a closed box body 50.SELECTED DRAWING: Figure 13
【課題】堰柱の側方にゲートが延設する河口堰の堰柱の補修や改修に際し、海水の遡上を遮蔽した状態で仮締切りを構築することのできる、仮締切り構築方法と仮締切り体を提供する。【解決手段】堰柱１と、堰柱１の側方に延設するゲート３と、を有する河口堰１０において、堰柱１の周囲に仮締切りを構築する、仮締切り構築方法であって、堰柱１の側方において、ゲート３に併設する仮ゲート２０を設置するＡ工程と、堰柱１の周囲の一方側に、第一分割函体３０を設置するＢ工程と、ゲート３を開放して、堰柱１の周囲の他方側に、第二分割函体４０を設置し、第一分割函体３０と第二分割函体４０を接続して締切函体５０を形成するＣ工程とを有する。【選択図】図１３
