Construction method for Lassen steel sheet pile underwater straining beam
The invention discloses a construction method for a Larsen steel sheet pile underwater straining beam, and relates to the technical field of bridge construction. The method includes the steps that a guide frame is manufactured and mounted; whether Larsen steel sheet piles deform or not and whether connecting locking openings are rusted or not are checked, and unqualified Larsen steel sheet piles are removed; a crane is adopted for inserting the Larsen steel sheet piles, the Larsen steel sheet piles are sleeved with pile caps for piling every time the Larsen steel sheet piles are inserted, and the perpendicularity of the Larsen steel sheet piles is guaranteed in the piling process; enclosing purlins are arranged on the whole length of an enclosing wall formed by the Larsen steel sheet piles, the enclosing purlins are welded to steel plate brackets, and steel waist beams are used as angle braces on the four corners of a Larsen steel sheet pile wall; and after construction of the underwater straining beam is completed, the Larsen steel sheet piles are dismantled. By the adoption of the construction method for the Larsen steel sheet pile underwater straining beam, the influence of water flow pressure, scouring force, water seepage and other problems existing in the underwater construction process on the construction process and the engineering quality can be solved, the construction progress is accelerated, the construction cost is reduced, and the engineering quality is improved.
本发明公开了一种拉森钢板桩水中系梁施工方法，涉及桥梁施工技术领域，包括：制作并安装导向架；检查拉森钢板桩是否变形，连接锁口是否锈蚀，剃除不合格的拉森钢板桩；采用吊车进行拉森钢板桩的插桩，每插入一块即套上桩帽进行打桩，打桩过程中注意保证拉森钢板桩的垂直度；在拉森钢板桩组成的围墙上全长设置围檩，围檩焊接于钢板牛腿上，并在拉森钢板桩墙四个转角上用钢腰梁做角撑；完成水工系梁的施工后进行拉森钢板桩的拆除。采用本发明的施工方法能够解决在水中施工过程中存在的水流压力、冲刷力、水体渗入等问题对施工过程和工程质量的影响，加快施工进度，降低施工成本，提升工程质量。
