3D reverse modeling of the Dapingshan Tunnel in Quanzhou

The Dapingshan Tunnel is located in the urban area of Quanzhou, with a total length of 1,524 meters and a maximum buried depth of 60 meters. The tunnel passes under the existing Dapingshan Tunnel of Quanxia Expressway, and the thickness of the rock layer between the two tunnels is only 5 meters, and the geological conditions change greatly and frequently, and the construction is extremely difficult. Our company uses three-dimensional scanning and reverse modeling technology to monitor and scan the tunnel, fit the point cloud patch, assist the construction party to detect the tunnel from time to time, assist the operator in operation and maintenance, and provide a variety of data formats for subsequent development.
