Pumping and grouting integrated constraint grouting reinforcement structure and construction method thereof
The invention provides a pumping and injecting integrated restrained grouting reinforcing structure and a construction method thereof.The reinforcing structure comprises a reinforcing body composed of a downcast pipe and a grouting pipe which are fixedly connected, and the reinforcing body is sequentially and alternately provided with grouting bag sections and downcast sections in the axial direction; an isolation end plate fixedly connected with the reinforcing main body is arranged between the grouting bag section and the dewatering section which are adjacent to each other; a grouting bag is installed on the grouting bag section, a grouting hole connected with an inner cavity of the grouting bag is formed in the side wall, located on the grouting bag section, of the grouting pipe, a precipitation filtering mechanism is installed on the precipitation section, and a precipitation hole connected with the precipitation filtering mechanism is formed in the side wall, located on the precipitation section, of the precipitation pipe. According to the pumping and injecting integrated restrained grouting reinforcing structure, the grouting pipes and the downcast pipes are alternately arranged, on one hand, the effect of downcast consolidation can be improved in the grouting process, and on the other hand, the bearing capacity of the steel pipes of the formed spaced bags is high.
本发明提供了一种抽注一体化约束注浆加固结构及其施工方法，加固结构包含由固定连接的降水管和注浆管所组成的加固主体，加固主体在轴向方向上依次交替设有注浆囊袋段和降水段，相邻的注浆囊袋段和降水段之间设有与加固主体固定连接的隔离端板；在注浆囊袋段安装有注浆囊袋，位于注浆囊袋段的注浆管侧壁开设有与注浆囊袋内部腔体相连的注浆孔，在降水段安装有降水过滤机构，位于降水段的降水管侧壁开设有与降水过滤机构相连的降水孔。本发明提供一种抽注一体化约束注浆加固结构，注浆管和降水管交替布置，一方面可以在注浆过程中提升降水固结的效果，另一方面形成的间隔囊袋的钢管承载力较高。
