Combined prestressed concrete pipe pile
The invention discloses a prestressed concrete pipe pile, and particularly relates to a combined prestressed concrete pipe pile. The combined prestressed concrete pipe pile comprises first piles, second piles and steel strand external members, first end steel plates on the same sides of the adjacent first piles and second end steel plates on the same sides of the adjacent second piles and the first piles are fixed, the end of one side of a steel strand penetrates into the pile from the top of the pile and is permanently locked with a steel connecting piece located at the bottom of the pile ina non-return mode, the end of the other side of the steel strand is tensioned, post-tensioning method prestress can be integrally applied to the multiple sections of first piles and the second piles extending in the direction of the pipe pile, thus the multiple sections of first piles and the second piles are promoted to be effectively integrated, and the uplift performance can be greatly improvedafter the first piles and the second piles are driven into the ground. The combined prestressed concrete pipe pile solves the technical problem of 'improving the uplift performance of the prestressedconcrete pipe pile', and has the advantages of being good in pipe pile construction quality, high in construction efficiency and the like.
本发明公开了一种预应力混凝土管桩，特别是一种组合式的预应力混凝土管桩，其包括第一桩、第二桩以及钢绞线套件，相邻第一桩的同侧第一端头钢板和相邻第二桩与第一桩的同侧第二端头钢板及第一端头钢板均相固定，钢绞线的一侧端部自桩顶部穿入，并与位于桩底部的钢材连接件进行永久止逆锁紧，通过张拉钢绞线的另一侧端部，即可对在管桩方向上延伸的多段第一桩及第二桩整体施加后张法预应力，进而促使多段第一桩和第二桩有效的成为一体，在其被打入地底后能够大幅度提升抗拔性能。本发明解决了“提升预应力混凝土管桩的抗拔性能”的技术问题，具备管桩施工质量好，施工效率高等优点。
