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

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of tunnel lining quality detection, in particular to a radar device suitable for tunnel lining quality detection and a using method. Background technique [0002] Tunnel engineering has become an indispensable part of my country's economic and technological development, and the quality and safety of tunnel lining has increasingly become the primary problem to be solved urgently. Therefore, a ground-penetrating radar technology for safe and efficient tunnel lining quality inspection came into being. pregnancy. [0003] According to the "Nondestructive Testing Regulations for Lining Quality of Railway Tunnels" (TB10223-2004 / J341-2004), it can be seen that the detection content of ground penetrating radar includes the emptying of the contact surface between concrete and surrounding rock; the thickness of support (lining), internal steel arches, Reinforcement distribution; inverted arch filling virtual slag, vir...

AI Technical Summary

Problems solved by technology

However, in view of the structural characteristics of the tunnel itself and the harsh construction environment on site, there are many inconveniences in the use of ground penetrating radar. Low, low radar lifting height, radar antenna cannot be closely attached to the tunnel wall, many radar signal interference factors, radar survey line distortion, etc.

[0004] Some of the existing radar devices require special processing technology, and the design is relatively difficult. Although some are simple in design and processing, the stability, stiffness and lifting height cannot meet the requirements.
