Rapid construction method of concrete fringe truss-steel sheet pile combined deep foundation pit unearthed ramp
The invention discloses a concrete fringe truss-steel sheet pile combined deep foundation pit unearthed ramp rapid construction method which comprises the steps that Larsen steel sheet piles are driven into earthwork behind a ramp side by side, it is guaranteed that the Larsen steel sheet piles are perpendicular in the inserting and driving process, and lock catches between the adjacent Larsen steel sheet piles are mutually buckled; a capping beam is constructed on the upper portions of the Larsen steel sheet piles and connected with a trestle on the rear portion of the ramp; under the support of the Larsen steel sheet piles, trestle bottom earthwork behind the ramp is excavated, and a concrete fringe truss and profile steel combined support behind the ramp is constructed. According to the technology of inserting the Larsen steel sheet piles, the Larsen steel sheet piles are driven side by side and connected through the small lock catches, supporting is provided for slope making of the ramp, and the problems that due to the fact that earthwork behind the ramp cannot be excavated, concrete fringe trusses cannot be poured, and profile steel combined supports cannot be erected are perfectly solved.
本发明公开了一种混凝土边桁架‑钢板桩组合深基坑出土坡道快速施工方法，其包括步骤：在坡道后方土方内并排打入拉森钢板桩，并保证插打过程中拉森钢板桩垂直，相邻拉森钢板桩之间的锁扣相互扣接；在所述拉森钢板桩上部施工压顶梁，与坡道后方栈桥连接；在所述拉森钢板桩的支护下，开挖坡道后方栈桥底土方，施工坡道后方混凝土边桁架及型钢组合支撑。发明插入拉森钢板桩的技术，通过拉森钢板桩并排打入并用小锁扣连接，为坡道放坡提供支承，完美的解决了坡后土方无法开挖导致无法浇筑混凝土边桁架及型钢组合支撑无法架设的问题。
