The invention relates to the technical field of building pile foundations, in particular to a prefabricated PHC pipe pile joint connecting structure and method, and aims to overcome the defect that pipe pile joints are easy to damage by arranging bolts, steel cylinders, cylinder structures, first bolt holes and second bolt holes comprising large hole parts and small hole parts which are communicated with each other on an upper-section pipe pile joint and a lower-section pipe pile joint. When a PHC pipe pile is prefabricated, a steel cylinder is pre-buried at a pipe pile joint, and a cylinder structure is arranged in an upper-section pipe pile joint, so that when the upper-section pipe pile joint and a lower-section pipe pile joint are connected, a bolt penetrating into a first bolt hole is aligned with and inserted into a large hole part of a second bolt hole, and a socket is rotated, so that the upper-section pipe pile joint and the lower-section pipe pile joint of the pipe pile are tightly connected into a whole; and finally, the joint seam of the upper-section pipe pile joint and the lower-section pipe pile joint is welded, and a stiffening plate is used for fixation. The PHC pipe pile joint connecting structure is suitable for pile body connection with high hammering frequency and larger vibration, high in universality, high in construction speed and high in construction progress quality requirement, and has good applicability in coastal mud flat sections.
本发明涉及建筑桩基技术领域，具体为一种预制PHC管桩接头连接结构及连接方法，通过在上下两节管桩接头设置螺栓、钢筒、筒体结构、第一螺栓孔和包括相互连通的大孔部和小孔部的第二螺栓孔来实现管桩接头处容易破坏的弊病。在PHC管桩预制时，在管桩接头处预埋钢筒，并于上节管桩接头内置筒体结构，以在当上下节管桩接头连接时，第一螺栓孔穿入的螺栓，对正插入第二螺栓孔的大孔部，旋转承插，使管桩上下节管桩接头紧密连接成一体，最后对上下节管桩接头接缝处焊接，并辅以加劲板进行固定。该PHC管桩接头连接结构适用于锤击频率高，振动较大的桩体连接，其通用性强，施工速度快，对施工进度质量要求高、沿海滩涂地段具有很好的适用性。
