Tunnel lining defect ground-penetrating radar detection system on basis of wall clinging type detection vehicle

Abstract

The invention discloses a tunnel lining defect ground-penetrating radar detection system on the basis of a wall clinging type detection vehicle. The tunnel lining defect ground-penetrating radar detection system comprises the wall clinging type detection vehicle, a GPS / INS (global positioning system / inertial navigation system) combined navigation module, a vehicular communication and transmission module, a movement controller, a ground-penetrating radar module and a ground workstation. The wall clinging type detection vehicle is used for being attached onto tunnel lining surfaces and can move according to set paths; the GPS / INS combined navigation module is used for navigating the detection vehicle; the vehicular communication and transmission module is used for being in two-way communication with the ground workstation, receiving instruction signals of the workstation and transmitting positioning signals and detection signals to the workstation; the detection vehicle can move under the control of the movement controller; the ground-penetrating radar module is used for detecting cavities in lining back surfaces; the ground workstation is used for designing and controlling the navigation paths for the wall clinging type detection vehicle, and detection data transmitted by the detection vehicle can be received, analyzed and displayed by the ground workstation; the GPS / INS combined navigation module, the vehicular communication and transmission module, the movement controller and the ground-penetrating radar module are mounted on the wall clinging type detection vehicle. The tunnel lining defect ground-penetrating radar detection system has the advantages that traffic closure can be omitted, and the tunnel lining defect ground-penetrating radar detection system is low in cost and high in precision.

Description

technical field [0001] The invention belongs to the field of tunnel detection in civil engineering, and relates to the detection of tunnel lining defects, in particular to a ground-penetrating radar detection system for tunnel lining defects based on a wall-attached detection vehicle. Background technique [0002] With the development of my country's economy, the comprehensive national strength is increasing, and the transportation construction has been developed rapidly. However, there are many mountainous areas in our country, and a large number of tunnels are often needed to be built in engineering construction. After a long period of use, cracks and holes will appear in the tunnel lining If no effective countermeasures are taken, it will seriously affect the traffic safety of the tunnel. At present, the detection of tunnel lining cracks in China mainly relies on manual detection, which generally requires experienced technicians to implement, with low efficiency and poor r...
