TECHNICAL FIELD

[0001] The application relates to the technical field of tunnel detection, in particular to a movable detection device for tunnel lining detection. BACKGROUND

[0002] The tunnel lining refers to a permanent supporting structure built on the inner wall of a tunnel to prevent the deformation and collapse of the rock and soil around the tunnel and ensure the use function and structural safety of the tunnel.

[0003] After the completion of the tunnel lining, detection instruments are needed for detection, which is crucial for ensuring the quality of the tunnel engineering, guaranteeing the structural safety and use function, and the tunnel lining detection mainly includes the detection of the thickness, strength, back cavity and steel bar distribution of the lining.

[0004] The existing tunnel lining detection method uses a detection trolley to carry detection instruments to detect the lining in multiple aspects, but the original detection trolley cannot normally walk in the tunnel after the installation of the track slab of the ballastless track, which affects the normal development of the detection work, and if a detection trolley compatible with the track is newly set up, time is wasted and the detection efficiency is affected.

[0005] Therefore, a movable detection device for tunnel lining detection is needed to solve the problem that the detection trolley cannot perform tunnel lining detection work in the tunnel with track slabs. CONTENT OF THE INVENTION
