Abstract

[0001] The utility model relates to the field of tunnel detection, and specifically relates to a lining detection device for tunnels, tunnel holes and diversion tunnels. Background Art
[0002] For the detection of tunnel lining structures, generally, personnel need to hold a detection radar and move along the axial direction of the tunnel.
