Method for dismantling bridge construction water-retaining steel cofferdam in advance
The invention discloses a method for dismantling a bridge construction water-retaining steel cofferdam in advance, which comprises the following steps of: reserving a groove and an embedded part on abridge bearing platform for installing a steel casing and a tower crane foundation section, and adding the steel casing on the outer side of the tower crane foundation section to serve as a water-retaining structure, so that the tower crane foundation section is in a water-proof state when being dismantled; and a purpose of firstly dismantling the water-retaining steel cofferdam and then dismantling the tower crane is realized; compared with the mode that in traditional construction, the water retaining steel cofferdam is dismantled after bridge construction and tower crane dismantling are completed, the water retaining steel cofferdam is dismantled and reused in advance, economic benefits of construction are maximized, cost is saved, and the method is used in the field of bridge construction.
本发明公开了一种桥梁施工挡水钢围堰提前拆除的方法，在桥梁承台上预留凹槽和预埋件，用以安装钢护筒和塔吊基础节，通过在塔吊基础节外侧增加钢护筒作挡水结构，使塔吊基础节拆除时处于隔水状态，从而实现可先拆除挡水钢围堰倒用，后拆除塔吊的目的，与传统施工中挡水钢围堰在桥梁施工及塔吊拆除完成后拆除的方式相比，将挡水钢围堰提前拆除和倒用，使施工的经济效益最大化，节省成本，此发明用于桥梁施工领域。
