GRP5000 Tunnel Scanning System

GRP5000 is integrated with manual track inspection trolley and high-speed laser scanning measurement technology., when the trolley walking on the track The high-speed rotating laser scanner scan surface for whole section of the tunnel, through the analysis of the laser signal of the transmission and receiving (intensity and phase difference), and can obtain images of the inner surface and tunnel lining each point on the surface of the distance from the center line of the track. The system can detect surface damages, clearance and deformation of tunnel, ellipse of tunnel, horizontal diameter and segment displacement.

Digital gray-scale map can be obtained by scanning data processing and expanding along the tunnel vault. This grayscale map is very clear. It can be divided into equipment such as overhead line and cracks with width of over 0.3mm. It can also be imported into TunnelMap tunnel digital management system as the basis of disease detection and management.

                                                                               Surface Damage Detection


The tunnel section at a certain length can be extracted and compared with the input vehicle clearance or equipment clearance to automatically generate the clearance analysis diagram relative to the current position of the track. If digital gray-scale map has been generated, it can also automatically indicate the invasion area in the gray-scale map.

  

Clearance Measurement


The tunnel profile is extracted at the specified interval. The data is filtered first (the stray points are filtered out), then the ellipticity analysis and the horizontal diameter are calculated. Provide decision basis for maintenance management department and data base for whole life cycle management of tunnel.
