TcpTunnel Scan - Maintenance

Project Definition
Each project is defined by the horizontal and vertical alignments, the tunnel design and point clouds. Data can be extracted from CAD drawings or imported from LandXML, IFC, and other formats.

Positioning and Orientation
The instrument must be positioned and oriented by coordinates, angle or resection. You can also get the current positioning performed by Topcon MAGNET® Field data collection software.

Data Collection
TcpTUNNEL Scan controls the scanning of the tunnel vault or face, with optional filters by station range and distance. A powerful 3D viewer allows you to review the point cloud and check measures.

Profiles
High-definition tunnel cross-sections are quickly calculated from the point cloud, and they can be consulted, edited and compared to the tunnel design, showing with different colors the underbreak and overbreak areas. Selecting any point of the profile on the screen, the laser pointer marks the position in the tunnel. On the other hand, measuring any point in the tunnel, project and as-built profiles at the corresponding station are represented.

Stake Out
TcpTUNNEL Scan facilitates the stake out of the tunnel front, for example the drill hole points for the next blasting excavation sequence, points on the template, rock bolts, road surface and points of the project file. The application calculates the exact position of each point from the scanned point cloud, a voiding the search for points from design by iterations and greatly increasing productivity.

The application can perform the verification of the minimum thickness of the lining shotcrete, as well as the subsequent calculation of the applied shotcrete volume.
