Technical Field

[0002] Water conservancy projects, including concrete-faced rockfill dams and pumped-storage power plants, are widely constructed in my country for a variety of purposes, including water resource management, power generation, irrigation, and flood control. These projects are often located in areas with complex geological conditions and variable climates, and therefore face various potential risks, including the development of cracks. Cracks not only affect the stability and safety of the projects but can also adversely impact the surrounding environment and residents' lives.

[0003] Existing concrete crack repair technologies primarily include surface patching, filling, pressure grouting, flexible sealing, and chemical grouting. These technologies are selected based on the crack's width, depth, and location, as well as its impact on the structure's bearing capacity and durability. Grouting is the most commonly used method and has demonstrated significant effectiveness in areas such as concrete crack repair, but it also has some drawbacks. For example, grouting technology is not suitable for all types of cracks.

[0046] According to the type, depth, width and position of the crack, the installation position of the device is reasonably pre-selected, a layer of glue is applied to the lower surface of the first glue-coated chassis 15, and then it is pressed at the installation position to fix the first glue-coated chassis 15. At the same time, the inside of the first rubber shell 14 is isolated from the outside world, and the electric control valve 5 is closed. Check whether the manual vacuum pump 10 can work normally, open the valve 34, and pull the vacuum pump connecting rod 24 back and forth. The vacuum pump connecting rod 24 drives the leather cup 23 to move up and down in the cylinder 22. When the vacuum pump connecting rod 24 is pulled upward, the gas in the first rubber shell 14 is extracted through the upper pipe 6 of the I-type suction cup, the horizontal pipe 45, the exhaust main pipe 44, and the exhaust pipe 9, so that the I-type suction cup is The suction cup assembly 4 is stably fixed on the concrete surface, the valve 34 is closed, and the second rubber-coated chassis 19 is arranged on the crack according to the preset position. By compressing the second telescopic rod 17, the steel needle 20 is inserted into the preset hole in the crack. The hole is made by artificial pre-drilling. Then a layer of glue is applied to the bottom of the second rubber-coated chassis 19, and then it is pressed to the installation position. The second rubber-coated chassis 19 is fixed and the inside of the second rubber shell 18 is isolated from the outside world. The electric control valve 5 on the exhaust branch pipe 41 is opened, the valve 34 is opened, and the exhaust cylinder connecting rod 24 is pulled back and forth. The gas passes through the exhaust hose 21, the exhaust gap layer 38, the exhaust branch pipe 41, the exhaust main pipe 44, and the exhaust pipe 9. When it is pulled out, the second glue-coated chassis 19 is stably fixed on the crack, the valve 34 and the electric-controlled valve 5 on the exhaust branch pipe 41 are closed, the electric-controlled valve 5 on the grouting branch pipe 40 is opened, the grouting machine 2 is turned on to start grouting, and the slurry is injected into the preset pores through the grouting main pipe 39, the grouting branch pipe 40, the grouting hose 35, and the steel needle 20. After the grouting is completed, the device cannot be disassembled immediately and it is necessary to wait for 24 hours; when disassembling, open the valve 34, unplug the exhaust pipe 9 from the exhaust nozzle 30 to release the air, then the vacuum state is exposed, and the first glue-coated chassis 15 and the second glue-coated chassis 19 can be removed, and the steel needle 20 can be taken out from the pore at the same time.
