Radar apparatus for tunnel lining quality detection, and application method of the same

The invention relates to a radar apparatus for tunnel lining quality detection, and an application method of the same. The radar apparatus for tunnel lining quality detection is characterized in that a hydraulic folding lifting mechanism is arranged above an automatic travelling mechanism, and is connected with the automatic travelling mechanism; a radar antenna clamping mechanism is arranged above the hydraulic folding lifting mechanism, and is connected with the automatic travelling mechanism; the hydraulic folding lifting mechanism includes an adjusting base plate and a telescopic arm on the adjusting base plate; the inclination angle of the adjusting base plate is adjustable, so that the inclination angle of the telescopic arm can be adjusted; and the telescopic arm is driven to lift or decline by a hydraulic drive apparatus. The radar apparatus for tunnel lining quality detection utilizes a laser range finder to measure the distance between the radar apparatus and the side wall of a tunnel in real time so as to timely adjust the turning of wheels, thus overcoming the problem that the measuring line is not stable during the radar detection process.
