Vehicle-mounted tunnel lining radar detection device

Abstract

The invention discloses a vehicle-mounted tunnel lining radar detection device. The vehicle-mounted tunnel lining radar detection device includes a special vehicle and a vehicle-mounted base arranged on the special vehicle, wherein the vehicle-mounted base is provided with an arch crown detection device, an upper side wall detection device and a lower side wall detection device. The vehicle-mounted tunnel lining radar detection device is characterized in that the front side and rear side of the vehicle-mounted base along the advancing direction of the special vehicle are vertically provided with an overhead line system rack touch sensing device respectively; the vehicle-mounted base is further provided with a PLC which is used for controlling the arch crown detection device, the upper side wall detection device, the lower side wall detection device and the overhead line system rack touch sensing devices; the arch crown detection device is arranged on the top of the vehicle-mounted base; the upper side wall detection device is arranged at the upper part of the side surface of the vehicle-mounted base; and the lower side wall detection device is arranged at the lower part of the side surface of the vehicle-mounted base. The vehicle-mounted tunnel lining radar detection device of the invention has the advantages of applicability for inner wall conditions of different tunnels, simple operation and disassembly and assembly convenient.

Description

technical field [0001] The invention relates to a tunnel side wall detection device, in particular to a vehicle-mounted tunnel lining radar detection device. Background technique [0002] A few years ago, the health status of the tunnel was initially detected by visual observation. This detection method is poorly representative and can only be drilled with a small amount of sampling, which is difficult to fully reflect the overall health status of the tunnel. In recent years, the non-destructive testing method of ground radar has good flexibility, and the lifting ground radar is used to scan longitudinally in the tunnel, which is widely used in tunnel detection. [0003] Overseas, Germany has developed a GeoRail-Xpress comprehensive inspection vehicle, and Japan has developed a tunnel lining inspection system using multi-channel geological radar technology, which can automatically lift the geological radar for inspection of operational railway tunnels, but there are complex ...

Problems solved by technology

At present, the vehicle-mounted tunnel inspection equipment invented in China is mainly an invention patent "tunnel inspection vehicle" published by Hunan Baolong Special Purpose Vehicle Co., Ltd., the publication number is CN200968855Y. The geological radar lifting device of the tunnel inspection vehicle adopts hydraulic drive to realize the radar slow It can only meet the inspection requirements of highway tunnel lining, and is not suitable for the inspection of electrified railway tunnel lining with complex inspection environment, and the tunnel inspection vehicle can only inspect one line at a time, and the inspection efficiency is low

The prototype of the tunnel vault / side wall detection device jointly developed by China University of Geosciences (Wuhan) and China Railway Fourth Survey and Design Institute Group Co., Ltd., the field test found that the device has achieved good detection results, but there are some problems, such as the vault / side wall The workload of the sidewall tunnel detection device is heavy when it is frequently assembled and disassembled, and the time for assembly and disassembly is short; the tunnel vault / side wall detection device is exposed to the open environment when it is not in the detection state, and the harsh outdoor environment will cause more damage to the equipment. Large; the tunnel vault / side wall detection device can only perform tunnel detection on two lines at the same time, and the detection efficiency is low; the detection positions of each tunnel are scattered, and the operation buttons are concentrated on one control cabinet, which is inconvenient to operate.
