A mobile intelligent detection device and operation method of rail transit tunnel geological radar

Abstract

The disclosure discloses a mobile intelligent detection device and operation method for rail transit tunnel geological radar. The console controls the working state of the rotating telescopic device. Under the control of the platform, the rotating telescopic device rotates, adjusts the working angle and working posture of the radar antenna detection device installed on the retractable slideway device, and maintains the fixed distance between the radar antenna and the tunnel lining wall required for detection ; Each rotary telescopic device is also equipped with a laser detection device to monitor obstacles on the tunnel lining surface in real time during the movement of the engineering vehicle, so as to avoid obstacles and adjust the detection route. The present invention can receive the laser detection result, can set the detection path and intelligently adjust the working posture of the detection system, and realize intelligent detection.

Description

technical field [0001] The disclosure belongs to the detection field, and in particular relates to a mobile intelligent detection device and an operation method of geological radar for rail transit tunnels. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] During the construction and operation of the tunnel, the lining, as the main stress structure, plays an important role in the safety of the tunnel. Affected by geological disasters, groundwater, complex loads, etc., tunnel lining diseases such as water seepage, mud and sand leakage, lining detachment, and lining back voids occur frequently, seriously affecting the safe operation of the tunnel. With the urgent need of tunnel defect detection business during the operation period, ground radar has played an important role in tunnel engineering quality inspection and tunnel defect detection ...

AI Technical Summary

Problems solved by technology

[0005] 1. Under normal circumstances, ground radar operators will use the method of hand-held ground radar antennas for detection, and the surface area of ​​the tunnel lining is relatively large. It is difficult to detect the lining of the entire tunnel simply by manually lifting the antenna, and the detection efficiency is very low.

If the part to be detected is high, it is necessary to use a lifting platform for detection, and the safety of the detection personnel cannot be guaranteed

[0006] 2. With the maturity of industrial robot technology, the geological radar mobile detection equipment that combines robot technology with geological radar detection technology can reduce the manual workload, but due to the imperfection of the equipment, the equipment can only detect part of the lining for a round-trip detection If it cannot cover the overall lining of the tunnel, it is easy to cause misjudgment of diseases, which has a great impact on the accuracy of tunnel disease diagnosis in the later stage

[0007] 3. Due to the working characteristics of geological radar equipment, the radar antenna needs to move at a constant speed during the detection process and the radar antenna needs to maintain a fixed distance from the tunnel lining during the movement process to obtain high-quality detection results. This point uses the existing manual detection way is hard to guarantee

However, it is difficult for the current ground radar mobile detection equipment to fully realize the stability of the equipment during the detection process.

[0008] 4. There are obstacles such as pipelines on the lining surface of rail transit tunnels. Currently known geological radar mobile detection equipment cannot set detection paths to intelligently avoid obstacles
