GLASS GMBH BAUUNTERNEHMUNG MINDELHEIM

Tubbings are reinforced concrete prefabricated components in the form of segments assembled to form rings which are used as linings for tunnels by linking the individual rings. They are used for tunnel constructions made with a tunnel boring machine. The cutting wheel of the tunnel boring machine moves within a steel jacket to dig up the soil, which is then removed by means of conveyor systems. The tunnel structure is built in the protection of the steel jacket.
