Spliced prefabricated pipe pile
The invention discloses a spliced prefabricated pipe pile, and belongs to the technical field of building structures. The prefabricated pipe pile comprises an upper pipe pile section and a lower pipepile section, wherein a joint is connected between the upper pipe pile section and the lower pipe pile section, and comprises an upper end plate, a lower end plate and a force transfer steel pipe connected between the upper end plate and the lower end plate; a closed grouting chamber is formed among the upper end plate, the lower end plate and the force transfer steel pipe; a first grouting hole for connecting a grouting pipe is formed in the upper end plate; and a plurality of extrusion holes for extruding out slurry in the grouting chamber are formed in the force transfer steel pipe; and after the grouting chamber is fully filled with the slurry and the slurry is extruded out from the extrusion holes, the slurry is solidified to form an expansion head, so that the overall pressure bearing performance and the pulling resistance of the prefabricated pipe pile can be improved when the stability of the joint is improved.
本发明公开了一种拼接式的预制管桩，属于建筑结构技术领域。本发明的预制管桩，包括上节管桩和下节管桩，上节管桩和下节管桩之间连接有接头，接头包括上端板和下端板，以及连接在上端板和下端板之间的传力钢管，上端板、下端板和传力钢管之间形成有封闭的注浆室，上端板上开设有用于连接注浆管的第一注浆孔，传力钢管上开设有若干个供注浆室内浆料挤出的挤出孔；当浆料填满注浆室后并从挤出孔挤出后凝固形成为扩大头，在提高接头处稳定性的同时，能够提高预制管桩整体的承压性能和抗拔性能。
