FIELD: underground construction. SUBSTANCE: device may be used for construction of tunnels by shield tunneling method. The device has base, supporting and transportation bridge, side curved and upper forms sections hinged to one another. Side sections are connected with base. Mechanism of breaking away of sections is made in the form of hydraulic cylinder whose rod is hinged to upper section, and cylinder is movably attached to base. Upper section is curved to correspond to contour of underground structure. Hinge unit of side sections located from one side and connecting them with upper section is made in the form of rocker movably mounted on axle located in holes of side and upper sections. EFFECT: higher quality of lining surface, reduced consumption of concrete mix and breaking-away force. 2 dwg
