ALWAYS ON THE RIGHT COURSE.

SAFE NAVIGATION through all ground conditions and complex jobsite processes. Reliable navigation and comprehensive monitoring technology make tunnel construction projects easier to manage. VMT systems utilize distributed multi-sensor networks to achieve precise and sensitive real-time tunnelling feedback and control. Easy to use system displays show status and log all critical geological and machine parameters to completely document tunnelling projects.

Machine performance and safety parameters are automatically recorded, evaluated and displayed during all phases of tunnelling. Construction progress is continuously updated with effective and easy to understand status displays.

VMT navigation systems continuously determine and display exact machine positions and excavation tool status to operators, engineers and managers. The comprehensive VMT solution keeps tunnel boring machines perfectly on course even when the geology is challenging and visibility is limited.

• Conventional Tunnelling – navigation of bolters and roadheaders for diverse tunnel profiles
• Tunnels built with segmental lining or rock support systems – precise control of mechanized tunnelling for all diameters and construction methods
• Microtunnelling – navigation systems for short and long straight tunnels as well as curved drives with small diameters

VMT information systems provide users with all critical tunnelling performance data in real time. Flexible ways of reporting, clear user guidance, reliable warning and monitoring systems are integrated with an intelligent tool set to effectively manage, control and document tunnel construction projects.

• Controlled Boring Process CBP – is a tunnel construction information system to record, analyze and evaluate tunnelling data for mechanized tunnelling. All the data is displayed in an easy to use Internet viewer

VMT geomonitoring and sensor systems track and capture the stability of terrestrial architectural objects in real time. They support tunnel construction by monitoring, analyzing and evaluating relevant processes. An important application is Automated Real-Time GeoMonitoring of buildings that are sensitive to subsidence. The system integrates multi-sensor networks which link geotechnical and geodetic sensors and can recognize early the risks of deformations.

VMT Surveying and monitoring sensor systems

• Profile Management System PMS for tunneling with roadheaders
• Ring Management Program RMP, Ring Convergence Measurement System RCMS for constructing tunnels with segmental lining, tailskin clearance measurement systems SLuM and GAPtrix, Grout Pressure Surveying System GPSS
• Press capacity control system JC Pipe, Automated Bentonite Lubrication System ABLS

VMT tunnel segment production systems monitor and document the individual process phases throughout the production, storage, transportation and installation of tunnel lining segments – improving quality control and reducing costs significantly.

• Segment Documentation System SDS – is a flexible control and documentation system for all lining segment production phases with bar code recording or RFIDs. It provides complete traceability for segment production and quality control. Storage and archiving of all data is possible in the TUnIS data base.

TUnIS – Tunnel and Underground Integrated Software Structure – is a standardized software platform that integrates the diverse functions via software modules from VMT and other suppliers. It achieves uniform operating and visualization concepts for optimum support and documentation of tunnel lining production.
