Large-diameter PHC pipe pile combined type connecting structure and construction method thereof
The invention discloses a large-diameter PHC pipe pile combined type connecting structure and a construction method thereof, and belongs to the technical field of pipe pile construction, the large-diameter PHC pipe pile combined type connecting structure comprises an upper-section pipe pile, a lower-section pipe pile and a fixing unit playing a connecting role, and the fixing unit comprises connecting sleeves arranged in the upper-section pipe pile and the lower-section pipe pile; the end plates are located between the upper-section pipe pile and the lower-section pipe pile, the steel plates are installed on a circle of the outer side of the connecting sleeve, a plurality of specially-made grooves are formed in the end plates, and specially-made plug pins correspondingly matched with the grooves are installed in the grooves. A quadruple connection reinforcing mode of end plate welding, the special plug pin, the connecting pin and the connecting sleeve is adopted, the bending resistance and the shearing resistance of a connector after large-diameter pipe piles are connected are improved to the maximum extent, and the end plates of the upper pipe pile and the lower pipe pile can be tightly aligned and attached through the special plug pin.
本发明公开了一种大直径PHC管桩组合式连接结构及其施工方法，属于管桩施工技术领域，包括上节管桩和下节管桩，以及起连接作用的固定单元，所述固定单元包括设置于上节管桩和下节管桩内的连接套筒，位于上节管桩和下节管桩之间的一对端头板，安装于连接套筒外侧一圈上的若干钢板，所述端头板上开设有多个特制凹槽，所述凹槽内部安装有与之对应契合的特制插销。本发明采用端头板焊接、特制插销、连接销、连接套筒四重连接加固方式，最大程度地提高了大直径管桩接桩后接头的抗弯和抗剪性能，并且特制插销能够使得上下两节管桩端头板紧密对位贴合。
