Unconnected reinforced concrete gallery segments are intended for the construction of circular linings of conduits, galleries and tunnels, respectively shafts with subterranean driving technology with the help of driving shields. This concerns thick-walled reinforced concrete elements of ring-shaped conical form which, after assembly of 4 pieces, form a tube in form of cylinder. Constituent elements forming a tube are connected with grooves and tongues. The contact surface of constituent tubes is smooth without made connection. The segments have built-in steel pipes allowing montage and sealing injection. They are designed according to ČSN 73 6203 for railway load with railroad train ČSD T and road load given by class A. They are designed for extra-banking height of 2 to 15.5 m.
