Description

Technical Field

[0001] This invention relates to the field of grouting reinforcement and repair technology in geotechnical engineering, and in particular to a grouting pipe with vibration function. Background Technology

[0002] Grouting reinforcement involves injecting grout into rock or soil through drilling, thereby improving the integrity and strength of the rock or soil mass. For grouting in water-rich sand layers, existing grouting pipes often experience sand particles clogging the grouting port during injection, and the grout frequently overflows along the outer wall of the grouting pipe. Therefore, there is an urgent need to develop a grouting pipe with vibration function. This pipe vibrates during the injection of grout into saturated sand layers, causing the sand layer structure to "liquefy," expanding the grout diffusion range, and preventing sand particles from clogging the grouting port and the grout from overflowing along the outer wall of the grouting pipe during injection.

[0045] Specifically, in this embodiment, the end of the second grouting pipe body 7 that is away from the first grouting pipe body 1 is conical.

[0046] Specifically, in this embodiment, before pressing the grouting pipe into the sand layer structure, the liquid in the grout stop plug 11 is first extracted by the infusion pump 13, so that the grout stop plug 11 is housed in the concave part of the first grouting pipe body 1. At the same time, the valve stem 41 in the control valve 42 is moved to the leftmost position, and the hydraulic pump 44 pressurizes the hydraulic pipe 37. The liquid pushes the hydraulic rod 36 to rotate a certain angle in the hydraulic cylinder 34.
