Spliced multi-section precast pipe pile and embedding method thereof
The invention discloses a spliced multi-section precast pipe pile and an embedding method thereof, and belongs to the technical field of building structures. The spliced multi-section precast pipe pile comprises an upper-section pipe pile, a lower-section pipe pile and a plurality of middle-section pipe piles located between the upper-section pipe pile and the lower-section pipe pile, wherein grouting pipes are arranged inside the side wall of the upper-section pipe pile and the side walls of the middle-section pipe piles, and the pipe piles are connected through connectors; and the connectorsare provided with closed grouting chambers defined by upper end plates, lower end plates and force transmission steel pipes, first grouting holes communicating with the grouting pipes are formed in the upper end plates, and a plurality of extrusion holes for allowing slurry inside the grouting chambers to be extruded out are formed in the force transmission steel pipes. At least one connecting pipe is connected between each upper end plate and the corresponding lower end plate and used for connecting the grouting pipes of every two pipe piles so that the grouting pipes between the adjacent pipe piles can communicate, the slurry can penetrate through the connectors located on the upper portions and be injected into the grouting chambers of the connectors located on the lower portions, grouting is carried out on connecting points with different heights, and the pressure bearing performance and the anti-pulling performance of the prefabricated pipe pile are further improved.
本发明公开了一种拼接式的多节预制管桩及其埋设方法，属于建筑结构技术领域。本发明的拼接式的多节预制管桩，包括上节管桩和下节管桩，以及位于上节管桩和下节管桩之间的若干节中节管桩，上节管桩和中节管桩的侧壁内均设置有注浆管，各节管桩之间通过接头连接；接头具有由上端板、下端板和传力钢管围成的封闭的注浆室，上端板上开设有与注浆管连通的第一注浆孔，传力钢管上开设有若干个供注浆室内的浆料挤出的挤出孔；上端板和下端板之间连接有至少一个连接管，连接管用于连接两节管桩的注浆管，使得相邻管桩之间的注浆管能够连通，从而使得浆料能够穿过位于上方的接头并注入位于下方的接头的注浆室了，实现对不同高度的连接点处进行注浆，进而提高预制管桩的承压性能和抗拔性能。
