Description

Technical Field

[0001] The utility model relates to the field of crack grouting, in particular to a crack grouting repair device for underground engineering. Background Art

[0002] Grouting machine is an important engineering machinery equipment. Grouting machine transports slurry material to cracks to achieve the effect of sealing cracks, strengthening the foundation of underground projects and improving their mechanical properties. However, the construction conditions of underground projects are relatively complex, and the terrain is often undulating, making it difficult for grouting machines to work. In addition, after the slurry is injected into the cracks by the slurry outlet pipe of the traditional grouting machine, slurry will inevitably flow out of the cracks, resulting in slurry waste and poor crack grouting sealing effect. When the slurry outlet speed is too fast, the slurry outlet pipe is difficult to fix in the cracks, which increases the difficulty of the grouting machine and reduces its work efficiency.
