Multi-section spliced pipe pile and embedding method thereof
The invention discloses a multi-section spliced pipe pile and an embedding method thereof, and belongs to the technical field of building structures. The multi-section spliced pipe pile comprises an upper-section pipe pile, a lower-section pipe pile and at least one middle-section pipe pile located between the upper-section pipe pile and the lower-section pipe pile, wherein the pipe piles are connected through connectors; closed grouting chambers defined by upper end plates, lower end plates and force transmission steel pipes are arranged inside the connectors, first grouting holes for communicating with 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; and at least one sleeve is connected between each upper end plate and the corresponding lower end plate and used for providing a channel for allowing the grouting pipes to penetrate through the connectors. Through the above arrangement, each connector of the multi-section spliced pipe pile can be grouted and form an expanded head, so that the pipe pile is provided with the plurality of expanded heads at different heights, and the pressure bearing performance and the pulling resistance of a pile body are improved.
本发明公开了一种多节拼接管桩及其埋设方法，属于建筑结构技术领域。本发明的一种多节拼接管桩，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至少一节中节管桩，各节管桩之间通过接头连接；接头内具有由上端板、下端板和传力钢管围成的封闭的注浆室，上端板上开设有用于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浆料挤出的挤出孔；上端板和下端板之间连接有至少一个套筒，套筒用于提供允许注浆管穿过接头的通道，因而本发明的多节拼接管桩的各接头处均可进行注浆并形成扩大头，使得管桩在不同高度具有多个扩大头，提高了桩体的承压性能和抗拔性能。
