Description

Technical Field

[0001] The utility model relates to the technical field of grouting, in particular to a ground drilling grouting plugging machine. Background Art

[0002] The grouting machine uses grouting filling technology to utilize the delamination voids formed in the overlying rock during the movement of the rock strata. The filling slurry is injected into the delamination voids at high pressure through a drill hole arranged on the ground. The high-pressure slurry compacts the lower rock strata, thereby increasing the delamination voids. The filling slurry after dehydration and compaction supports the overlying rock strata, slows down the spread of rock strata movement to the surface, effectively controls surface collapse, and ensures that surface structures are not damaged.

[0003] However, the existing drilling grouting machine has some limitations. The grouting head is relatively large, which is inconvenient in actual operation and difficult to move and align with the borehole. In addition, there is a gap between the borehole and the grouting pipe. When the grouting mechanism is started, the slurry will be ejected instantly, causing the slurry to splash out of the gap, which not only wastes the slurry but also pollutes the surrounding ground. This phenomenon is more frequent when the borehole passes through the wall irregularly. Therefore, a ground drilling grouting plugging machine is proposed to solve the above problems.
