Description

Technical Field

[0001] The present invention relates to the technical field of construction, and particularly to a device for repairing micro-cracks in prefabricated components with solid waste. Background Art

[0002] In the process of building industrialization, precast concrete components are widely used due to their advantages such as high efficiency and environmental protection. However, the annual scrapped amount due to their micro-cracks (50 - 500 μm) exceeds 12 million tons, causing a direct economic loss of about $8 billion. Traditional repair technologies have significant defects: epoxy resin materials are difficult to penetrate into micro-cracks (penetration depth < 0.1 mm) due to their high viscosity (> 1000 cps), and the interfacial peeling strength after repair is less than 60% of that of intact components; the utilization rate of industrial solid wastes such as slag is low (< 35%), and existing split-type equipment (such as CN108643669A) results in a single crack repair time exceeding 2 hours and a material waste rate > 20%; the carbon fiber reinforcement method of CN112376889A cannot handle concealed cracks, and the microwave curing equipment of CN113585621B has an energy consumption as high as 5 kW·h / m and poor adaptability to metal cracks. For the repair of micro-cracks, how to carry out reinforcement and reduce material waste is an important problem to be solved. Therefore, there is an urgent need to invent a device for repairing micro-cracks in prefabricated components with solid waste to solve the problem of repairing micro-cracks in prefabricated components. Summary of the Invention

[0022] The operation steps of the prefabricated part micro - crack solid waste repair device of the present invention are as follows: Step 1: First, load cyanoacrylate monomer into the first material box 6. It is in a liquid state in the first material box 6 at room temperature. Load slag into the storage bin 27. The preparation work is completed. Step 2: The operator holds the handle 2 and first performs a pretreatment operation. At the crack position of the prefabricated part, through the drive of the first motor 3 on the brush 14, the dust and impurities at the crack position are removed, and then through the blowing of the blower 9, the drying is accelerated. Step 3: Crush the slag, load some waste materials into the storage bin 27. The rotation of the stirring rods 30 will be driven by the second motor 22 to crush the slag to 0.1 - 2 mm. Load an appropriate amount of water into the storage bin 27, and then start the second material pump 26. The mixture in the storage bin 27 is led to the crack through the liquid outlet pipe 15. The solid particles in the mixture will be deposited in the crack. Repeat the operation multiple times until there are enough solid particles in the crack. Step 4: Start the bonding stage. This stage is crucial. The nozzle of the through-feed pipe 11 should be oriented towards the crack position. Feed materials outward through the first material pump 7, and then atomize the materials through the vaporization pump 19. The output pressure of the vaporization pump 19 is 0.2 - 0.5 MPa. Atomize the cyanoacrylate into an aerosol with a size of 10 - 50 μm. After being assisted by the fan 9 for diffusion, it contacts the moisture in the crack and polymerizes. A three-dimensional interpenetrating network curing layer is formed within 30 seconds. The metal in the crack can be quickly bonded through the adhesive to achieve reinforcement of the crack. The bonding strength reaches 5.2 MPa, and the material utilization rate exceeds 95%. It is applicable to the resource utilization of construction waste and the efficient repair of concealed micro-cracks.
