GUIDE DEVICE FOR UNDERWATER DESCENDING OF COFFERDAM STRUCTURE USED IN PIER REPAIR/REINFORCEMENT WORK
To provide a guide device for underwater descending of a cofferdam structure used in a pier repair/reinforcement work which is also usable for a pier having such a shape that a diameter is not constant and a pier having an inclined shape.SOLUTION: A guide device for underwater descending of a cofferdam structure used in a pier repair/reinforcement work includes a rail 3 for descending installed on an outer peripheral surface of a pier 1, and a slide supporting arm 5 which projects inward from an inner peripheral surface of a cofferdam structure 2 toward the rail 3 for descending and has a slide member 4 capable of sliding through the rail 3 for descending on the tip of projection, is configured so that the cofferdam structure 2 can be descended and moved to the pier 1 by sliding the sliding member 4 on the tip of the slide supporting arm 5 along the rail 3 for descending, the slide supporting arm 5 is configured so as to be expandable/contractive, and elongation energization means 6 that always energizes the slide supporting arm 5 in an elongation direction is provided.SELECTED DRAWING: Figure 1
【課題】径が一定でない形状の橋脚や傾斜した形状の橋脚に対しても利用可能な橋脚補修・補強工事に用いる仮締切り構造体の水中降下用ガイド装置を提供すること。【解決手段】橋脚１の外周面に設置される降下用レール３と、この降下用レール３に向けて仮締切り構造体２の内周面から内向きに突設され突出先端に降下用レール３を滑走可能な滑走部材４を有する滑走支持アーム５とを備え、降下用レール３に沿って滑走支持アーム５先端の滑走部材４が滑走することで橋脚１に対し仮締切り構造体２が降下移動可能に構成され、滑走支持アーム５は、伸縮自在に構成されていると共に、滑走支持アーム５を常時伸長方向に付勢する伸長付勢手段６を備えている。【選択図】図１
