Segmental lining
The tunnel wall is made up of rings (usually 1 to 1.5 meters long), which in turn consist of different tunnel segments. The number of segments per tunnel ring, shape of the segments, reinforcement and finish is custom-made and determined in consultation for each customer.
The tunnel segments have to withstand the loads on the tunnel, but during drilling they also have to withstand the pressing forces of the tunnel boring machine. Socea produces these high-quality tunnel segments both in the factory in Oelegem (local and export) and in temporary factories set up abroad. Since the progress of the tunnel boring machine depends on the quality and speed of the manufacturing, the production unit must be efficient and effective.
Socea's extensive knowledge and experience guarantees a smooth completion of the project.
