Abstract

Procedure to open the segments that in each case have to be joined as last, especially on the roof, and that have to lean on each other on the front side, in a preferably annular shoring of mine galleries or tunnels, made of profiles made of steel that have flanges, in galleries made by gallery advance machines, for example milled, in the area of the front sector of the machine, characterized by the use of a clamping group that can be hydraulically driven and that is made up of a lift cylinder and a piston displaceable in the longitudinal direction as well as two claw bodies, said clamping group being hooked, after the insertion of the segments of a bow or shoring ring per se known, with eyelet heads provided in their two ends, between the two claw bodies made in the form of a body of bank (cats) and previously held by releasably pressing on the tabs of the s segments, and said group being extended until the extreme sections of the two covered segments, initially juxtaposed, mutually support each other with their front side as a result of the transverse displacement.
