Description

TECHNICAL FIELD

[0001] The present application relates to the field of concrete repairing equipment, in particular to a concrete rapid repairing and reinforced bonding device and method. BACKGROUND

[0002] The surface of hydraulic structures will be damaged due to the impact of foreign objects, water scouring, congenital defects caused by design and construction quality, or repeated freezing and thawing under water saturation. If the surface damage of concrete is not repaired in time, it will continuously cause new damage, even large area of exposed reinforcement, corrosion or complete rusting, reduce the effective cross section, and reduce the load bearing capacity of the component, affecting the safety of the project. Therefore, when the concrete surface has honeycomb or aging damage of more than 3 / 4 of the thickness of the protective layer, the reinforcement starts to corrode, and the component produces corrosion cracks or hollowing, warping and other symptoms, it should be repaired.

[0003] The commonly used repairing material is concrete with a certain amount of additives, such as fly ash, anti-seepage agent, expanding agent, rust inhibitor, high-efficiency water reducing agent, and external coating. This kind of material is very important for increasing the compactness and strength of the concrete surface, improving the anti-freezing and thawing performance of the concrete, prolonging the service life of the concrete, and increasing the service life of the concrete project. The construction process generally adopts the method of "chiseling the old and repairing the new", including base surface treatment, interface agent brushing, epoxy mortar construction, and maintenance.

[0004] However, the current repairing material for such dangerous conditions has poor bonding performance with concrete, and the construction process is extremely complex. And after several flood seasons after repair, the following problems are still common:

[0005] 1) The elastic modulus, shrinkage rate, and thermal expansion coefficient of the epoxy mortar and the concrete material have large differences, so the compatibility of the two is poor, the bonding strength in the humid or underwater environment is unstable, and under the change of external conditions, cracking and voiding at the bonding interface are easy to occur, leading to the separation of the epoxy mortar repair body and the concrete structure.

[0006] 2) Under long-term sunlight conditions, the epoxy mortar gradually becomes brittle, and is seriously worn out by continuous scouring of a large amount of high-speed water flow.

[0007] The existence of these problems makes the surface of the repaired structure still unstable, easy to cause further damage, and causes significant economic loss and safety risk. SUMMARY
