Abstract RU 2166091 C1

FIELD: underground construction; applicable in construction of tunnels and mine shafts. SUBSTANCE: device has a tunneling shield with shield jacks, forms with hydraulic cylinders of their moving, pressure ring and branch pipe for supply of concrete mix to space between shield body and forms. Device also has a supporting collar embracing inlet part of window of underground structure over which perimeter ends of reinforcing wire ropes are attached. Secured to shield body on the side of location of shield hydraulic jacks are drums on which the other secured end of reinforcing wire ropes is wound. Reinforcing wire ropes are located between external surface of forms and internal surface of shield body. Drum has a brake secured to the shield body. EFFECT: higher quality of erected structure and simplified initial engagement of shield. 4 dwg
