Existing pile foundation grouting reinforcement hole sealing device and using method
The invention discloses an existing pile foundation grouting reinforcement hole sealing device and a using method, and belongs to the technical field of pile foundation reinforcement. An expansion body similar to a capsule is adopted to seal a channel, the actual working expansion range of the expansion body is large, and one expansion body can be used for completely blocking the grouting channel. The existing pile foundation grouting reinforcement hole sealing device comprises a plurality of pipe fittings arranged in a sleeving mode, wherein gaps are formed between the adjacent pipe fittings, the pipe fitting located on the outermost side is the first pipe fitting, and the first pipe fitting is wrapped with an elastic bag; the elastic bag communicates with the first pipe fitting; and the first end face of the elastic bag is fixedly connected with the first pipe fitting, and the second end face of the elastic bag is slidably connected with the first pipe fitting.
本发明公开了一种既有桩基注浆加固封孔装置及使用方法，属于桩基加固技术领域，采用类似于胶囊的膨胀体对通道进行封闭，并且膨胀体的实际工作膨胀范围较大，可以使用一个膨胀体对注浆通道进行完全封堵，包括套设的多个管件，相邻的管件之间具有间隙，位于最外侧的管件为第一管件，第一管件包覆设置有弹性囊；弹性囊连通第一管件；弹性囊的第一端面固定连接第一管件，弹性囊的第二端面滑动连接第一管件。
