Dismantling system and dismantling method for steel sheet piles special for bridge cofferdam construction

XU YONGMEI / HE YONG

The invention discloses a steel sheet pile dismantling system and dismantling method special for bridge cofferdam construction, and belongs to the technical field of bridge construction. A steel sheet pile dismantling system special for bridge cofferdam construction comprises a moving seat, moving wheels are arranged at the bottom of the moving seat, a rotating seat is arranged on the moving seat, a pulling assembly used for pulling out a steel sheet pile is arranged on the rotating seat, a lifting assembly is arranged on the moving seat, and a displacement assembly is connected to the lifting assembly. The displacement assembly is connected with a containing base used for containing the steel sheet pile, a supporting base is arranged on the moving base, and an auxiliary lowering assembly used for obliquely lowering the steel sheet pile is arranged at the end, away from the moving base, of the supporting base. The steel sheet pile can be prevented from being damaged during lowering, and the subsequent reuse effect of the steel sheet pile is guaranteed; and the steel sheet piles are stacked in order, the placing occupied space of the steel sheet piles is effectively reduced, meanwhile, the placing stability of the steel sheet piles is improved, and potential safety hazards possibly caused by loosening and sliding of the steel sheet piles are eliminated.

本发明公开了一种桥梁围堰施工专用钢板桩拆除系统及拆除方法，属于桥梁施工技术领域。一种桥梁围堰施工专用钢板桩拆除系统，包括移动座，移动座的底部设置有移动轮，移动座上设置有旋转座，旋转座上设置有用于钢板桩拔除的拔除组件，移动座上设置有升降组件，升降组件上连接有位移组件，位移组件上连接有用于放置钢板桩的放置座，移动座上设置有支撑座，支撑座远离移动座的一端设置有用于钢板桩倾斜下放动作的辅助下放组件；本发明可避免钢板桩下放时受到损坏，保证钢板桩后续的重复使用效果；且使钢板桩堆放整齐，有效减少其摆放占地空间，同时提高钢板桩摆放的稳定性，消除钢板桩可能存在的因松动滑移所造成的安全隐患。
