TEMPORARY GATE PROVIDED TO TEMPORARY COFFERDAM AND TEMPORARY GATE LIFTING SYSTEM CONSTITUTING TEMPORARY COFFERDAM
To provide a temporary gate capable of raising/lowering provided to a temporary cofferdam, and a temporary gate lifting system constituting a temporary cofferdam.SOLUTION: In a weir that has a weir column 10 and a main gate 14 that extends sideward of the weir column 10 and is capable of being lifted up and lowered down, a temporary cofferdam is constructed around the weir column 10. A box body 20 is arranged to enclose the weir column 10 and a temporary gate 73 extends sideway of the box body 20. The weir column 10 has a first drop groove 13 formed on a side face thereof, and multiple temporary supports 71 that has second drop grooves 72 are vertically installed being spaced from the side of weir column 10. The box body 20 has a wall body having a third drop groove. Each of the multiple temporary supports 71 is provided with a tow tool 78. Temporary gates 73 are dropped into each drop groove 72 and each of the temporary gates 73 is hung so as to be lifted up and down by the corresponding traction tool 78.SELECTED DRAWING: Figure 19
【課題】昇降自在な仮締切り体の備える仮設ゲートと、仮締切り体を構成する仮設ゲート昇降システムを提供する。【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１４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を構成し、堰柱１０の周囲に配設される箱体２０の側方に延設する、仮設ゲート７３であって、堰柱１０の側面に第１落とし込み溝１３が設けられ、堰柱１０の側方に間隔をおいて第２落とし込み溝７２を備える複数の仮支柱７１が立設し、箱体２０は第３落とし込み溝を備えた壁体を有しており、複数の仮支柱７１にはそれぞれ牽引具７８が設置されており、各落とし込み溝７２に仮設ゲート７３が角落としされるようになっており、各仮設ゲート７３が対応する牽引具７８に昇降自在に吊持されている。【選択図】図１９
