TUNNEL ROUTING DETECTION, TUNNEL SEGMENT INJECTION PROPAGATIONCONTROL
›
From the surface along the tunnel route to the tunnel bottom, we determine the change in the underground structure along the route and the changes in the lateral direction along the route with the geophysical survey methods. For this reason, the presence of water on the spot is a pre-determined.
As a result of the site tests and laboratory studies, we are carrying out geotechnical studies including preparation of sections of Tunnel Route Engineering Geology, determination of Tunnel Opening Technique.
During the production of tunnels, high resolution ground radar (GPR) measurements made at the same time in the direction of progress in NATM tunnels can be used to determine possible gaps or sludge empties by determining the gap, groundwater, discontinuity and faulting in the direction of progress.
During the production of tunnels, high resolution ground radar (GPR) surveying made at the same time in the direction of progress in NATM tunnels can be used to determine possible gaps or sludge empties by determining the gap, groundwater, discontinuity and faulting in the direction of progress.
We determine undamaged surveying techniques to ensure that no gaps remain behind the tunnel segments. We are rightfully proud of having done the first application successfully in this regard in Turkey.
