Description

Technical Field

[0001] The utility model relates to the technical field of grouting machines, in particular to a high-pressure grouting machine. Background Art

[0002] Grouting is the process of injecting grout into cracks, fractured zones, or joints and fissures in a building's foundation. Grouting can improve the impermeability and integrity of the ground or building, improve foundation conditions, and ensure safe building operation.

[0003] The grouting operation needs to be carried out with the help of a grouting machine. The grouting machine uses high pressure to inject the grouting liquid with waterproof and leak-proof effect into the gap along the passage of the grouting machine, pipeline, expansion screws, and gap. The grouting liquid expands in the gap when it comes into contact with water to form a dense structure to achieve a waterproof effect.

[0004] During the waterproofing construction process, the grouting machine may need to perform grouting operations at multiple locations. When the grouting machine completes the grouting operation at one location, it is necessary to pause the grouting machine and continue the grouting operation after moving to the next location where grouting is required.

[0005] Due to the characteristic of grouting liquid solidifying extremely quickly after coming into contact with water, once the grouting machine stops working, the pipeline and nozzle are easily blocked, and the slurry in the slurry box is also prone to solidification, making it impossible to continue the grouting operation in time, delaying the construction progress and affecting the construction efficiency of the entire grouting operation.
