The invention relates to a pipe pile sinking construction method for an overwater trestle, and belongs to the technical field of trestle construction. Comprising the following steps that S1, steel pipe piles are prepared; s2, a steel pipe pile guide system is arranged, bailey truss combined section steel originally needing to be built forms a cantilever guide frame, and a positioning frame is installed on a section steel part of the cantilever guide frame; s3, a guide system is installed, and a cantilever guide frame is installed on the constructed trestle structure; s4, the pile position reserved hole position is determined through the positioning frame with the front end of the bailey truss as the reference; s5, steel pipe piles are installed; and S6, the position and the height of the steel pipe pile are checked. The whole cantilever guide frame formed by combining the bailey truss needed by the trestle and the profile steel is adopted, the steel pipe piles are precisely positioned through the guide frame, and it is guaranteed that the problems that in the sinking process of the steel pipe piles, the installation precision of the steel pipe piles is low, and the stability of a steel trestle construction platform is poor due to the fact that the steel pipe piles are affected by the outside world are solved.
本发明涉及一种水上栈桥的管桩下沉施工方法，属于栈桥施工技术领域。包括以下步骤：S1：钢管桩准备；S2：设置钢管桩导向系统，将原本需要搭建的贝雷桁架组合型钢构成悬臂导向架，在悬臂导向架的型钢部分安装定位架；S3：安装导向系统，将悬臂导向架安装在搭建完成的栈桥结构上；S4：通过定位架以贝雷桁架的前端为基准确定桩位预留孔位；S5：安装钢管桩；S6：检查钢管桩的位置及高度。本发明通过采用栈桥本身需使用的贝雷桁架与型钢组合形成的整体悬臂导向架，通过导向架对钢管桩完成精定位，保证钢管桩在下沉的过程中不会受到外界的影响而导致管桩安装精度低、钢栈桥施工平台稳定性差的问题。
