TUNNEL CONSTRUCTION
- Limited availability of GPS signals -Tunnels often exist in areas where the reception of GPS signals limited or non existent. Inertial Navigation Systems can operate independently without relying on signals making them valuable for maintaining position and orientation data underground.
- Guiding Tunnel Boring Machines (TBMs) - Navigation Systems are commonly used to guide Tunnel Boring Machines (TBMs). These large machines excavate tunnels and INS ensures steering and navigation along the tunnel path ensuring alignment with the intended route.
- Monitoring tunnel deformation -During and after tunnel construction it is crucial to monitor the integrity of the tunnel. Inertial Navigation Systems can track any deformations or movements within the tunnel structure providing information for assessing its stability.
- Mapping and surveying confined spaces - Inertial Navigation Systems assist in mapping and surveying the interior of tunnels which are confined spaces that require precise measurements and mapping.
These applications highlight how Inertial Navigation Systems play a role in ensuring tunnel construction by overcoming challenges posed by limited GPS signal availability guiding TBMs accurately monitoring structural integrity and assisting with mapping tasks, in confined spaces.
It is crucial to create documentation of the built conditions and assess the geological situation within the tunnel.
Mapping emergency exit routes in tunnels can be achieved using navigation systems. This information plays a role in ensuring safety measures and evacuation protocols during emergencies.
When it comes to tunnel construction integrating INS into equipment like drilling machines and mucking equipment allows for tracking of their location and movement. This tracking ensures efficiency and precision in tunnel construction.
Inertial Navigation Systems provide real time data on the progress of tunnel excavation. This information is valuable for project management allowing construction teams to assess progress and make adjustments to the construction plan.
For tunnel networks or multiple tunnels being constructed Inertial Navigation Systems prove helpful in navigating through underground structures while aligning different sections accurately.
Using Navigation systems helps reduce errors in tunnel construction by providing positioning and navigation information. This is especially important, for maintaining desired alignment and preventing deviations from planned routes.
Inertial Navigation Systems play a role in tunnel construction by addressing the difficulties caused by GPS signal availability. They greatly contribute to the overall success and safety of tunneling projects.
