Abstract

The invention discloses a coastal concrete reinforcing and monitoring integrated device and method. The coastal concrete reinforcing and monitoring integrated device comprises a reinforcing mechanism, a signal tester, an anchoring mechanism and an external direct-current power source mechanism. The reinforcing mechanism comprises a CFRP grid and a conducting layer, and the conducting layer wraps the CFRP grid; the signal tester is electrically connected with the conductive layer; the anchoring mechanisms are arranged at two ends of the conductive layer; and the external direct-current power supply mechanism is electrically connected with the CFRP grid and the concrete to be reinforced to form a closed electric loop. The method comprises the steps that to-be-reinforced concrete is cleaned; anchoring mechanisms are fixedly mounted at the two ends of the surface of the tension side of the to-be-reinforced concrete, the CFRP grid is tensioned, and a conductive layer is sprayed or cast in situ, so that the reinforcing mechanism is in contact connection with the to-be-reinforced concrete; mounting a signal tester on the conductive layer; and an external direct-current power supply mechanism is mounted, so that the external direct-current power supply mechanism, the reinforcing mechanism and the to-be-reinforced concrete form a closed electric loop By using the method, the problem of erosion and degradation of concrete in coastal areas is practically solved.

Description

technical field [0001] The invention relates to the technical field of coastal erosion concrete structure reinforcement, in particular to an integrated device and method for reinforcement and monitoring of coastal concrete. Background technique [0002] At present, the erosion and deterioration of concrete structures in coastal areas of our country is extremely serious, even causing huge losses to our economy. Therefore, how to repair and strengthen reinforced concrete structures in coastal areas scientifically and rationally has become an urgent problem to be solved in the domestic development process. [0003] For the erosion and deterioration of concrete bridges in coastal erosion areas, there are mainly the following three core problems: First, the corrosion and durability of bridge structures. For example, the concrete materials of bridge structures cannot effectively resist the erosion of seawater and media; The crack work and the poor impermeability of the concrete m...

AI Technical Summary

Problems solved by technology

[0003] For the erosion and deterioration of concrete bridges in coastal erosion areas, there are three core problems: first, the corrosion and durability of bridge structures, for example, the concrete materials of bridge structures cannot effectively resist the erosion of seawater and media; The crack work and the poor impermeability of the concrete material itself lead to a large amount of seawater and chloride ions intruding into the structure, and the chloride ions intruding into the concrete cause serious corrosion of the steel bars; the second is the damage and degradation of the mechanical properties of bridge structures, such as bridge structures The bearing capacity and stiffness of the bridge are significantly reduced; the third is that it is impossible to effectively monitor and control the erosion and deterioration of the bridge structure

[0004] However, the existing bridge structure reinforcement technology or reinforcement methods are not suitable for the repair and reinforcement of degraded bridge structures in coastal erosion areas, such as external FRP reinforcement methods, prestressed FRP reinforcement methods, FRP mesh (or grid) / cement-based composite Material (or polymer mortar) reinforcement methods and cathodic protection-based FRP reinforcement methods cannot solve the above three core problems at the same time, but can only partially solve the above problems. Therefore, it is urgent to carry out research on bridge structure reinforcement methods in coastal erosion areas. Research
