Ring Convergence Measurement System RCMS

During a tunnelling project with segmental lining, a number of different forces, either natural or advance-related, act on the tunnel and the rings installed. To detect potential risks caused by deformations as early as possible, the Ring Convergence Measurement System RCMS has been developed.

There is the option of simultaneously capturing absolute movements (uplifts/settlements) of the ring by installing a segment reference prism.

Other VMT products calculate the optimum ring sequence and monitor the ring planarity as well as centred ring installation in the tailskin.
