Usage:

Unconnected reinforced concrete gallery segments are intended for the construction of circular linings of conduits, galleries, and tunnels, respectively shafts with technology of subterranean driving with the help of driving shields with outer diameter 200, 256, 305 and 360 cm. This concerns thick-walled reinforced concrete elements of ring-shaped conical form which, after assembly, form a tube in the form of cylinder. Constituent elements are connected with grooves and tongues. The segments have built-in steel pipes allowing assembly and sealing injection. They are designed according to ČSN 73 6203 for railway load with the railroad train ČSD T and road load given by class A. They are designed for extra-banking height of 2 to 15.5 m.
