[0002] The vacuum-assisted grouting device is a device used for repairing and reinforcing concrete structures, mainly used for processes such as grouting, grouting and plugging. It generates a vacuum negative pressure environment and assists the pressure to inject slurry into concrete cracks or cavities to improve the repair effect and construction efficiency. This device usually includes the following main components: 1. Vacuum pump: used to create a vacuum environment, suck out air and moisture, create a pressure difference, and help the slurry fully fill the gaps in the concrete structure. 2. Slurry bucket: used to store concrete repair materials such as cement slurry, polymer slurry, etc., to ensure continuous feeding during construction. 3. Grouting pump: used to transport slurry from the slurry bucket to the concrete structure and inject the slurry into the part to be repaired through the pipeline system. 4. Control system: used to control the operation of equipment such as vacuum pumps and grouting pumps, adjust the vacuum degree and pressure, and ensure the stability and accuracy of the construction process. The vacuum-assisted grouting device has important applications in the field of concrete structure repair and reinforcement. It can improve construction efficiency, reduce material waste, and ensure the quality and reliability of the repair effect.

In order to meet the use requirements, a vacuum-assisted grouting device is urgently needed. Utility Model Content
