Bag type grouting prefabricated pipe pile and construction method thereof
The invention relates to a bag type grouting prefabricated pipe pile and a construction method thereof, belongs to the technical field of prefabricated piles, and aims to solve the problems that in the prior art, a pipe pile is prone to loosening or inclining due to insufficient pulling resistance and bonding force, the overall supporting performance is reduced, and the stability and safety of the structure are affected. Comprising a grouting pipe, a bag, a fixing ring and a tightening belt, the grouting pipe is arranged in the length direction of the pipe pile, and the grouting pipe is fixedly connected with the pipe pile; the bag is cylindrical, openings are formed in the two ends of the bag, the bag can be expanded, and the bag is arranged on the pipe pile in a sleeving mode; the two ends of the bag are fastened to the pipe pile through the two fixing rings correspondingly, and the grouting pipe communicates with the space formed by the bag and the pipe pile. The tightening belts sleeve the outer surface of the bag, at least one tightening belt sleeves the outer surface of the bag, and the tightening belts can be expanded after the bag is filled with slurry and expands; and the bag expands outwards to form barbs after grouting, so that the pulling resistance is improved, and the stability and the safety of the whole structure are enhanced.
本发明涉及一种囊袋式注浆预制管桩及其施工方法，属于预制桩技术领域，用于解决现有技术中的管桩抗拔力和粘接力不足容易导致管桩发生松动或倾斜，导致整体支撑性能下降，从而影响了结构的稳定性和安全性的问题；包括：注浆管、囊袋、固定环和收紧带，注浆管沿着管桩的长度方向布置，注浆管和管桩固定连接；囊袋呈筒状且囊袋两端均设置有敞口，囊袋可膨胀，囊袋套装在管桩上；两个固定环分别将囊袋的两端紧固在管桩上，注浆管和囊袋与管桩形成的空间连通；收紧带套在囊袋外表面，囊袋外表面套有至少一根收紧带，当囊袋中填充浆液膨胀后可将收紧带撑开；囊袋注浆后往外扩形成倒刺，提高了抗拔力，增强了整体结构的稳定性和安全性。
