Tunnel lining quality testing equipment and method

Abstract

The invention discloses tunnel lining quality testing equipment which comprises a rail car; guide rail wheels are mounted at the bottom of the rail car, a geological radar detection device is mounted in the rail car, a mounting seat is mounted at the upper end of the rail car, and a mounting groove is formed in the upper end of the mounting seat. The invention further discloses a tunnel lining quality testing method which comprises the following steps: S1, a worker installs a mounting box in the mounting groove, fixing rods on the two sides are arranged in a downward inclined mode and two vertical fixing rods are arranged close to each other due to the gravity of the fixing rods, then an electric telescopic rod is started, and the output end of the electric telescopic rod moves to drive a U-shaped rack plate to move. Through the cooperation of the electric telescopic rod and the U-shaped rack plate, the mounting box can be limited, the stability of the mounting box is guaranteed, meanwhile, the angle of a collection sliding trolley can be adjusted, simplicity, convenience and rapidness are achieved, the mounting box can be detached conveniently, and meanwhile the collection sliding trolley can be detached conveniently.

Description

technical field [0001] The invention relates to the technical field of tunnel detection, in particular to a tunnel lining quality testing device and method. Background technique [0002] Geological radar detection technology is a kind of geophysical detection technology. At present, more and more attention is paid to the non-destructive testing of tunnel quality. The geological radar is used to detect the defects of the tunnel lining in the construction stage, and the detected defects in the tunnel detection are sorted out and analyzed. The characteristics of radar images of typical defects. Finally, by comparing the results obtained with traditional detection methods, it is found that ground radar has the advantages of continuous, non-destructive, fast and accurate in tunnel quality detection. It is one of the rapidly developing and effective non-destructive detection methods. . [0003] After the construction of the tunnel lining is completed, its quality needs to be insp...

AI Technical Summary

Problems solved by technology

[0003] After the construction of the tunnel lining is completed, its quality needs to be inspected. By installing the geological radar detection equipment on the rail car, the receiver slides along the side wall of the tunnel, and transmits the information to the geological radar processing device, and the quality of the lining side wall can be obtained. Whether there are gaps, etc.; but the current receivers are mostly fixed angles, it is inconvenient to adjust their angles, and at the same time, it is inconvenient to disassemble; such as a tunnel lining quality inspection equipment with application number CN201920959836.2
