Embodiment 1

[0042] Such as figure 1 As shown, a radar-based device for automatic tunnel monitoring includes three parts, namely track 1, moving car body 2, adjustable rotating rod 3 and control device.

[0043] The track 1 is made of polymer material with light weight and high strength, and is fixed on the tunnel vault, and is connected with the tunnel vault by steel bolts, and the extending direction is parallel to the axial direction of the tunnel;

[0044] And there is a gap on the bottom of the track along the axial direction of the tunnel, the mobile car body is installed on the track and slides along the track; there are grooves on the track 1 for the The mobile car body 2 slides;

[0045] Specifically, the track 1 includes an L-shaped piece 1 and an L-shaped piece 2; the L-shaped piece 1 and the L-shaped piece 2 are arranged symmetrically with respect to the tunnel axis, and a gap is formed between them, and the L-shaped piece 1 and the L-shaped piece 2 The two L-shaped pieces ar...

Embodiment 2

[0063] The difference between this embodiment and Embodiment 1 is:

[0064] The mobile car body of this embodiment is an automatic control trolley, and the control mechanism is a driving mechanism and a controller. The controller is used to control the driving mechanism and change the rotation direction and / or speed of the driving mechanism. The driving mechanism can Driving the movement of the mobile wheels of the mobile vehicle body.

Abstract

The invention provides a tunnel lining quality automatic detection device and a working method, the tunnel lining quality automatic detection device comprises a track, a mobile vehicle body, a control mechanism, a processor and a rotating rod, the track is fixed on a tunnel vault, the extending direction of the track is parallel to the axial direction of a tunnel, and the mobile vehicle body is slidably arranged on the track; a rotating rod is arranged at the lower end of the mobile vehicle body, and the relative angle between the rotating rod and the mobile vehicle body is adjustable; a radar antenna device is arranged at the lower end of the rotating rod, and a control mechanism used for controlling the moving vehicle body to move and a processor used for receiving and processing data collected by the radar antenna device are arranged on the moving vehicle body. The tunnel lining surrounding rock can be automatically and comprehensively detected in real time.

Description

technical field [0001] The disclosure belongs to the technical field of automatic monitoring, and in particular relates to a tunnel lining quality automatic detection device and a working method. 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] The current transportation construction needs to meet various complex and harsh geological conditions, and under these circumstances, various diseases are more likely to occur in tunnel construction, such as a series of common problems such as insufficient thickness of primary sprayed concrete during construction, and cavities due to insufficient surrounding rock, or during the use of tunnels. Lining leakage, lining erosion and lining crack damage and other diseases. Therefore, it is particularly important to strengthen the quality inspection of tunnel lining during construction and to monitor the ...
