Pier-side bracket with double-wall steel boxed cofferdam as foundation and construction method
The invention relates to the technical field of bridge construction, and discloses a pier-side bracket with a double-wall steel boxed cofferdam as a foundation and a construction method. The pier-side bracket comprises column feet, steel pipe piles, a connecting system, an attached wall and distribution beams, wherein the column feet are arranged along the double-wall steel boxed cofferdam and located at the top end of a bulkhead; the steel pipe piles are erected on the column feet; the connecting system is arranged between the adjacent steel pipe piles; the attached wall is arranged between the steel pipe piles and a pier; and the distribution beams are arranged at the tops of the steel pipe piles. The pier-side bracket has the following advantages and effects that the double-wall steel boxed cofferdam is directly used as the foundation, a driven pile or drilled pile foundation does not need to be arranged, stress is definite, the structure is stable and reliable, the construction risk is reduced, and the construction period is shortened; and the bracket does not need to be arranged to be inclined, so that an opposite-pulling structure with a complicated structure is omitted, and the construction cost is reduced.
本发明涉及桥梁施工技术领域，公开了一种以双壁钢套箱围堰为基础的墩旁托架及施工方法，包括柱脚，其沿双壁钢套箱围堰设置，且位于隔舱板顶端；钢管桩，其架设于柱脚上；连接系，其设置于相邻钢管桩之间；附墙，其设置于钢管桩和桥墩之间；分配梁，其设置于钢管桩顶部。本发明具有以下优点和效果：本申请由于直接利用双壁钢套箱围堰作为基础，不需要设置打入桩或钻孔桩基础,受力明确，结构稳定可靠，降低了施工风险,节省了施工工期；不需要将托架设置成倾斜状,省去了结构复杂的对拉结构，降低了施工成本。
