Evaluation and detection system for apparent defects of civil engineering structure

Abstract

The invention belongs to the technical field of civil engineering, and discloses an evaluation and detection system for the apparent defects of a civil engineering structure. The system comprises an image acquisition module, a pressure detection module, a central processing module, a drone module, an image processing module, a defect evaluation module, a life prediction module and a display module. The image acquisition module and the drone module can collect image data of each corner of the engineering structure through a drone in order to obtain complete image data, so an evaluation result is accurate; the life prediction module can judge the possible control section of the structure, calculate the stiffness attenuation coefficient under the influences of load, shrinkage and creep and predict the remaining service life of the structure after the structure is loaded according to numerical analysis or mechanics knowledge; the remaining life prediction result is continuously updated bycombining actual measurement information; and the life of the structure can be accurately predicted.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to an evaluation and detection system for apparent defects of civil engineering structures. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] Civil engineering is a general term for the science and technology of building various land engineering facilities. It not only refers to the applied materials, equipment and technical activities such as survey, design, construction, maintenance and repair, but also refers to the object of engineering construction. That is, various engineering facilities built on the ground or underground, on land, directly or indirectly serving human life, production, military affairs, and scientific research, such as houses, roads, railways, pipelines, tunnels, bridges, canals, dams, ports, power stations, Airports, offshore platforms, water supply and drainage,...

AI Technical Summary

Problems solved by technology

[0007] In the current evaluation of civil engineering structures, the image acquisition is limited, and the blind parts of the engineering structure cannot be collected, and the obtained data is incomplete; at the same time, the life of the engineering structure cannot be accurately predicted

[0008] Existing evaluation methods have the problems of difficult detection of structural defects in civil engineering in service, inaccurate detection results, inability to dynamically monitor the changing trend of disasters, complex evaluation process, and inconsistent evaluation results with the actual situation.
