Bridge main pier foundation double-layer steel sheet pile diaphragm wall combined cofferdam construction method
The invention discloses a bridge main pier foundation double-layer steel sheet pile diaphragm wall combined cofferdam construction method, and relates to the field of bridge main pier cofferdam construction, and the method comprises the following steps: S1, main pier cofferdam steel casings are inserted at intervals in the range of a rectangular cofferdam; s2, inner-layer steel sheet piles and outer-layer steel sheet piles are inserted and driven in a framing mode, the bottom ends of the inner-layer steel sheet piles and the bottom ends of the outer-layer steel sheet piles are inserted below a riverbed line, and the inner walls of the inner-layer steel sheet piles and the inner walls of the outer-layer steel sheet piles are both coated with waterproof soil layers; s3, an underwater diaphragm wall is constructed between the inner-layer steel sheet pile and the outer-layer steel sheet pile, and the upper portion of the underwater diaphragm wall and the lower portion of the steel sheet pile have a coincident section; and S4, the inner-layer steel sheet pile is pulled out. The steel sheet pile has the advantages that the steel sheet pile can be repeatedly used, the steel sheet consumption is reduced, and the construction cost is effectively controlled.
本申请公开了一种桥梁主墩基础双层钢板桩地连墙组合围堰施工方法，涉及桥梁主墩围堰施工领域，其包括以下步骤：S1、在矩形围堰的范围内间隔插打主墩围堰钢护筒；S2、分幅插打内层钢板桩和外层钢板桩，使内层钢板桩和外层钢板桩底端插入至河床线以下，内层钢板桩和外层钢板桩的内壁上均涂覆有防水土层；S3、在内层钢板桩和外层钢板桩之间施工水下地连墙，水下地连墙上部与钢板桩下部存在重合段；S4、拔出内层钢板桩。本申请具有实现钢板桩的重复利用，降低了钢板的耗费量，使施工成本得以有效控制的效果。
