Prestressed pipe pile splicing method based on self-bottom-sealing type cast-in-place expanded pile head
The invention discloses a prestressed pipe pile splicing method based on a self-bottom-sealing type cast-in-place expanded pile head, which comprises the following steps of: firstly, constructing a self-bottom-sealing type expanded pile head reinforcement cage system, and inserting the self-bottom-sealing type expanded pile head reinforcement cage system into a hollow pipe hole at the upper end of a prestressed concrete pipe pile to be subjected to pile splicing operation; a supporting hoop device and a concrete supporting formwork are installed on the prestressed concrete pipe pile, and a pipe pile pouring external formwork is installed on the concrete supporting formwork; and finally, concrete cast-in-place pile splicing operation is conducted in the pipe pile cast external formwork at the upper end of the prestressed concrete pipe pile. According to the prestressed pipe pile splicing method based on the self-bottom-sealing cast-in-place expanded pile head, the pile splicing operation of the prestressed concrete pipe pile and the self-bottom-sealing cast-in-place concrete reinforced pile can be achieved, the procedure is simple, operation is convenient and fast, and the pile splicing efficiency is high; the poured newly-spliced pile has the advantages of being good in corrosion resistance and rust resistance, high in strength and pressure resistance, good in stability, safe and reliable.
本发明公开了一种基于自封底式现浇扩大桩头的预应力管桩接桩方法，首先，构建自封底式扩大桩头钢筋笼系统，并插入至待接桩作业的预应力混凝土管桩上端中空管孔内；再在预应力混凝土管桩上安装支撑抱箍装置和混凝土支撑模板，并在混凝土支撑模板上安装好管桩浇注外置模板；最后，在预应力混凝土管桩上端的管桩浇注外置模板内进行混凝土现浇注接桩作业。本发明一种基于自封底式现浇扩大桩头的预应力管桩接桩方法，能够实现预应力混凝土管桩和自封底式现浇注混凝土钢筋桩的接桩操作，程序简单，操作方便快捷，接桩效率高；浇筑后的新接桩具有抗腐蚀、抗锈蚀性能好，强度和抗压性高，稳定性好，安全可靠的特点。
