Cast-in-place pile splicing connecting structure and construction method thereof
The invention discloses a cast-in-place pile splicing connecting structure and a construction method thereof. The connecting structure comprises an original cast-in-place pile after final setting, a butt joint retaining head connected to the top of the original cast-in-place pile, a butt joint reinforcement cage connected to the upper portion of the butt joint retaining head and a pile casing connected to the outer side of the butt joint reinforcement cage; the butt joint reinforcement cage comprises an outer reinforcement cage body and an inner reinforcement cage body connected into the outer reinforcement cage body, and the inner reinforcement cage body is connected with the butt joint retaining head; the outer reinforcement cage body and the inner reinforcement cage body are connected through a connecting piece; and the bottom of the outer reinforcement cage body is in a grid shape. According to the cast-in-place pile splicing connecting structure and the construction method thereof, through the arrangement of the pile casing, the casting quality can be guaranteed, and safety is high; through the arrangement of the double reinforcement cage bodies, the strength of the cast-in-place pile is guaranteed, and the butt joint pile part can be further reinforced through the outer reinforcement cage body during pile splicing; and through expanded connection of a pile splicing area, force transmission at the connecting position is continuous, and better overall stability is achieved; and guide construction is conducted through a guide pipe, the hoisting precision is guaranteed, and the construction time is saved.
本发明公开了一种灌注桩接桩连接结构及其施工方法，连接结构包含终凝后的原灌注桩、连接于原灌注桩顶部的对接留头、连接于对接留头上方的对接钢筋笼以及连接于对接钢筋笼外侧的护筒；对接钢筋笼包含外钢筋笼和连接于外钢筋笼内部的内钢筋笼，内钢筋笼与对接留头连接；外钢筋笼和内钢筋笼间通过连接件连接；所述外钢筋笼底部为网格状。本发明通过护筒的设置，可利于保证浇筑质量且安全性较高；通过双钢筋笼的设置，既保证了灌注桩的强度，又利于在接桩时通过外钢筋笼对接桩部位的进一步加固；通过对接桩区域的扩大连接，使得连接处的传力持续且有更好的整体稳定性；通过引导管进行引导施工，保证了吊装精度和节省施工时间。
