Abstract
A grouting pipe with a vibration function includes: a grouting pipe body provided with a hydraulic control structure, a vibration structure and a grouting hole control structure; wherein the vibration structure is rotatably arranged inside the grouting pipe body, and the hydraulic control structure is provided outside the grouting pipe body; the grouting hole control structure is provided on an internal wall of the grouting pipe body, and the hydraulic control structure is connected to the grouting hole control structure through a first hydraulic pipe. The grouting pipe solves the technical problems that conventional grouting pipes may be blocked by sandy soil during a press-in process, and it is difficult for the slurry to diffuse.
