Advanced detection vehicle for road and tunnel for the geological disasters no destruction

Advanced detection vehicle for road and tunnel

This vehicle is used to detect and find out the geological disasters such as cavities, subsidence and permeable water in advance. in the road or tunnel without arousing any destruction.

A few days ago, the new detection equipment-the tunnel advance detection vehicle rolled off the assembly line in Shijiazhuang City. The product can perform non-contact detection of internal defects in tunnels, roads and other sections, sense potential safety hazards in advance, and play a huge role in ensuring the safety of personnel and the safe and efficient tunnel construction.

China is the country with the most and longest tunnels in the world. Due to various influences such as deep burial, long distance, and submerged excavation, the geological and hydrogeological conditions are complex. Unforeseen tunnel construction will encounter faults, collapses, and karsts. , Rock bursts, water bursts, mud bursts, gas bursts, etc., bring many hidden dangers to the safe and rapid construction of the tunnel. For this reason, the development of a special equipment that can detect geological abnormalities in advance and long distances during tunnel excavation, and improve the accuracy and accuracy of prediction, has become an urgent problem in the process of safe and rapid tunnel construction.

The tunnel advanced detection vehicle uses high-frequency electromagnetic pulse reflection technology to detect the distribution of the medium ahead and underground. Compared with detection technologies such as sonar and electrical methods, it has the advantages of fast scanning speed, high resolution, light weight, and non-destructive testing. . During the operation of the rover, the vehicle can fix the parking space and move the robotic arm for radar detection. It can also travel at a slow speed while extending the detection arm to perform omnidirectional and non-dead-angle inspections on the tunnel and road surface. The maximum scanning width of the radar is 12 meters. The maximum detection depth can reach more than 50 meters, the overall stability of the vehicle is good, and the movement is flexible.

It is understood that the tunnel advanced detection vehicle R&D team has successively focused on key core technologies such as broadband high-power transmitters, high-sensitivity acquisition systems, low-frequency shielding geological radar antennas, intelligent identification of geological anomalies, and the stability of vehicle detection under complex conditions. It greatly improves the accuracy of geological anomaly prediction, and provides advanced detection equipment for the safe construction of tunnels and roads, regular inspections of internal geological defects, and ensuring safe construction and traffic.
