摘要： A tunnel construction made of tubbings forming a lining or casing for a tunnel includes a plurality of contact points between adjacent tubbings. These contact points comprise adhesive material acting to connect adjacent tubbings to each other at predetermined points. The contact points are distributed around the circumference of the tubbing rings at predetermined locations which depend on the type of the tubbing used and also on the points of pressure application by the driving shield of a tunneling or heading machine. The present tubbings have recesses in their surface facing into the tunnel whereby the recesses have a substantially trapezoidal shape to form three ribs extending substantially in the direction of the longitudinal tunnel axes.
