Threaded connection trestle steel pipe pile construction method
The invention discloses a threaded connection trestle steel pipe pile construction method and relates to the technical field of pipe pile construction. The construction method for the threaded connection trestle steel pipe pile comprises the following specific operation steps that S1, when the steel pipe pile is machined in a factory, male threads are welded to an upper portion of a first section of the steel pipe pile, female threads are welded to a lower portion of a second section of the steel pipe pile, and the steel pipe pile is transported to a site after being manufactured, male threads are welded according to the actual hole depth on site, the height of the male thread left during later dismantling is consistent with that of a riverbed, and navigation safety is guaranteed. According to the construction method for the threaded connection trestle steel pipe pile, through the male threads, the female threads and a rubber pad which are machined in a customized mode, the anti-drawing bearing capacity of the trestle steel pipe pile is greatly improved, and the trestle steel pipe pile is convenient to disassemble, safe, reliable and high in construction efficiency, compared with an original production mode, a rotary grab head is used during installation and disassembly, risks caused by field welding, personnel underwater cutting and the like are avoided, personal safety of operators is ensured, construction efficiency is improved, and economic investment is reduced.
本发明公开了一种螺纹连接栈桥钢管桩施工方法，涉及管桩施工技术领域。该螺纹连接栈桥钢管桩施工方法，具体操作如下：S1、钢管桩厂内加工时将公螺纹焊接在第一节钢管桩上部，母螺纹焊接在第二节钢管桩下部，制作完成运输至现场，其中公螺纹需根据现场实际孔深，确保后期拆除时遗留的公螺纹高度与河床一致，保证通航安全。该螺纹连接栈桥钢管桩施工方法，通过定制加工的公螺纹、母螺纹、橡胶垫，使栈桥钢管桩抗拉拔承载力大大提高，方便拆卸，安全可靠，施工效率高，与原有生产方式相比，进在安装和拆卸的时候使用旋转抓头，避免了现场焊接与人员水下切割等产生的风险，确保作业人员的人身安全，提高施工效率，降低经济投入。
