Concrete maintenance and reinforcement treatment method

Abstract

The invention relates to a concrete maintenance and reinforcement treatment method. The method comprises the following steps: (1) carrying out nondestructive treatment on the concrete base surface defects; (2) carrying out rust-proof treatment on reinforcing bars; (3) carrying out concrete alkalinity recovery treatment; (4) carrying out concrete crack repairing treatment; (5) daubing new and old concrete adhesives; (6) daubing inorganic polymer mortar and carrying out curing; (7) sticking carbon fiber cloth; (8) brushing an inorganic water and salt injury resistant concrete protective agent; and (9) brushing a surface self-cleaning material, thus completing construction. The method has the following beneficial effects: rust can be removed or prevented from the reinforcing bars to protect the reinforcing bars and prevent further corrosion; by adopting the carbon fiber cloth for reinforcement, the concrete structure has the characteristics of high strength, light weight, simpleness and convenience in construction and corrosion resistance; the bearing capability of the beam body is improved; the deflection of the structure is reduced; the construction efficiency is greatly improved by adopting the airless spraying and coating operations; the coating is saved by 30%; and by brushing the self-cleaning material, the structure has the self-cleaning capability, thus avoiding cleaning or reducing the cleaning frequency.

Description

technical field [0001] The invention relates to a construction technology, in particular to a concrete repair and reinforcement treatment method. Background technique [0002] The treatment of base surface defects is the most fundamental and important step before the repair and reinforcement of all reinforced concrete structures, and it is the first step in determining the quality of repair and reinforcement. Because there is no advanced equipment for the treatment of the base surface of the original reinforced concrete structure, hammers or air picks (air hammers) are usually used to remove the expanded, loose, peeled, and corroded concrete, and the steel wire brush is used to slowly remove it. Grinding the rust on the steel surface. Because the hammer cannot accurately and uniformly control the hitting force, and the impact energy of the air pick (air hammer) is too high—up to 100 joules or more—the original structure of reinforced concrete is greatly damaged by concussio...

AI Technical Summary

Problems solved by technology

[0007] To sum up, there are many problems in the daily maintenance and reinforcement of reinforced concrete structures (such as bridge structures, tunnel structures, etc.) in China. If the old equipment, old materials, and old construction methods are still used, it will affect the construction of bridges and tunnels in our country. Post-maintenance poses a serious safety hazard, which not only poses a threat to people's lives and property, but also seriously wastes national resources
