Directional grouting device and grouting method
The invention belongs to the technical field of underground engineering construction, and provides a directional grouting device and a grouting method. The device comprises a guide pipe, a rotary sleeve and a guniting pipe, the guide pipe is arranged on the outermost layer and directly makes contact with the stratum. Guide windows are arranged on the side wall of the guide pipe at equal intervals in the longitudinal direction, and the central axes of all the guide windows coincide; an alignment groove is formed in the tail end part of the guide pipe; the rotary sleeve is inserted into the guide pipe, and the side walls of the rotary sleeve and the guide pipe are attached to each other; the side wall of the rotating sleeve is provided with a plurality of windows at equal intervals in the longitudinal direction. The central axes of the two adjacent windows deflect by a set angle; a plurality of guide blocks corresponding to the alignment grooves are arranged at the tail end part of the rotating sleeve; the guniting pipe is inserted into the rotating sleeve, a guniting panel and a sealing bag are arranged at the guniting end of the guniting pipe, and the sealing bag is attached to the guniting panel in a sealed mode.
本发明属于地下工程施技术领域，提供了一种定向注浆装置及注浆方法。其中，该装置包括导向管、旋转套管及喷浆管；所述导向管设置在最外层，直接与地层相接触；所述导向管侧壁沿纵向设置有等距的导向窗，且所有导向窗中轴线重合；所述导向管尾端部设有对准槽；所述旋转套管插设于所述导向管中且两者侧壁相贴合；所述旋转套管侧壁沿纵向设置有等距的若干开窗；相邻两开窗的中轴线偏转设定角度；所述旋转套管尾端部设置有多个与所述对准槽对应的引导块；所述喷浆管插设于所述旋转套管中，所述喷浆管的喷浆端头设置有喷浆面板及密封囊袋，所述密封囊袋与喷浆面板密封贴合。
