Distance sensor system

In the last phase of the immersion process, the team makes use of sensor probes with a reach of some 40 cm. These probes are used when sealing the joint with a GINA profile.

Dual purpose

These sensors serve a dual purpose. On the one hand, the sensor readings can be used to precisely determine the distances between the different tunnel segments. On the other hand, the operator can use the differences between the readings to draw conclusions regarding the segment’s secondary end. In other words: by meticulously measuring the primary end of the segment, the immersion team can establish the exact position of the secondary end.

Geocon employed the distance sensor system in the Busan-Geoje Fixed Link project, and will be using this method for the Chioggia Flood Barrier project.
