Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and particularly relates to a building construction grouting device. Background Art

[0002] Grouting involves injecting solidifying materials, such as cement, lime, or other chemicals, into the rock and soil within a defined area beneath the foundation to fill cracks and pores, prevent leakage, and improve the integrity, strength, and rigidity of the rock and soil. Grouting is commonly used to create an anti-seepage curtain in water-retaining structures such as gates, dams, and dikes, and is a primary foundation treatment measure for hydraulic structures.

[0003] Grouting involves injecting a fluid and gelling slurry into cracks in the ground or building through drilling (or pre-buried pipes) in a specific ratio, cementing and hardening it into a solid mass to achieve the engineering goals of anti-seepage, consolidation, and reinforcement. Grouting can be categorized by function, including curtain grouting, consolidation grouting, backfill grouting, contact grouting, joint grouting, reinforcement grouting, and crack grouting. Grouting materials can be categorized as cement grouting, clay grouting, asphalt grouting, and chemical grouting.

[0004] In order to enhance the overall structural stability of a building, the prior art usually requires the use of a grouting construction method to perform grouting operations on the gaps in the building. The current grouting methods for building gaps mainly use manual labor and grouting machines. When grouting is performed manually, only small-scale filling construction can be carried out, the construction efficiency is low, and the labor cost is high. Another method is to use a traditional high-pressure grouting machine. Since there are many gaps in the construction project and they are discontinuous, the efficiency of filling and grouting the building gaps using this method is not high, and the high-pressure grouting machine is inconvenient to move. In addition, due to the large number of discontinuous gaps in the concrete grouting process, the grouting operation time is often too long, and the concrete in the grouting machine needs to be continuously stirred. Due to the characteristics of the concrete slurry itself, it is easy to adhere to the inner wall of the grouting machine and is difficult to remove. Utility Model Content
