Dismantling method of steel cofferdam for water retaining in bridge construction
The invention belongs to the field of bridge construction, and particularly discloses a dismantling method of a steel cofferdam for water retaining in bridge construction, and the steel cofferdam in a shallow water area can be effectively dismantled by adopting the method. According to the dismantling method, a No.0 block of a bridge serves as an operation platform, firstly, a cantilever beam is arranged on the No.0 block, then a walking cross beam with a lifting device is arranged on the cantilever beam in a sliding mode, then steel cofferdam blocks forming a steel cofferdam are cut and dismantled, and finally the lifting device is used for lifting the steel cofferdam blocks and lifting the steel cofferdam blocks to a safety area along with the walking cross beam. Dismantling and hoisting of the steel cofferdam are achieved; the whole process is easy and convenient to operate and high in construction efficiency and is not limited by the water depth of a water area, the construction difficulty of workers is greatly reduced, the safety of high-altitude operation is guaranteed, and the construction cost can be saved.
本发明属于桥梁施工领域，具体公开了一种桥梁施工挡水用钢围堰的拆除方法，采用该方法能够有效拆除位于浅水域的钢围堰。该拆除方法通过将桥梁的0号块作为作业平台，首先在0号块上设置悬臂梁，然后将带起吊装置的行走横梁可滑动地设置在悬臂梁上，接着将构成钢围堰的钢围堰块切割拆除，最后利用起吊装置将钢围堰块吊起，并随行走横梁吊运至安全区域，实现钢围堰的拆除吊运；整个过程操作简便，施工效率高，且不受水域水深的限制，大大降低了工人的施工难度，利于保证高空作业的安全，并可节省施工成本。
