Abstract

The invention discloses a rapid and non-destructive comprehensive detection device for roadbed diseases of an operating expressway, which consists of a retractable vehicle frame, a walking device, a contact electrode, a pie-shaped wave detector, an electrode lifting system, a spray system, a wave detector lifting system, and an automatic vibration source. , control device and other parts. The technical effect of the present invention is that the device improves the traditional high-density electrical method and Rayleigh wave working form, and integrates two detection devices into the same device for simultaneous detection, and the detection data can be comprehensively invoked and jointly interpreted, improving Improve the accuracy of roadbed disease detection. The device is easy to install, operate and disassemble, improves the detection efficiency, reduces the impact of detection on traffic, and is a roadbed disease detection device suitable for operating expressways.

Description

technical field [0001] The invention relates to a rapid and non-destructive comprehensive detection device for roadbed diseases of operating expressways. Background technique [0002] The subgrade is the main body of road engineering, which bears the weight of the road surface, the weight of the body and the traffic load. In order to ensure a good use condition, the subgrade must have sufficient rigidity, strength and stability. In order to ensure that the roadbed is maintained in a good condition, it is necessary to detect the roadbed disease and the state of use, so that the roadbed disease can be found in time and appropriate maintenance measures can be taken. As the roadbed is a hidden project, it is difficult to find it through routine inspections. It is often only discovered when the roadbed disease develops to a certain extent and is reflected on the road surface. At this time, the roadbed disease has developed to a very serious level and missed the best maintenance....
