High-stability tunnel supporting device

Abstract

The invention discloses a high-stability tunnel supporting device. The high-stability tunnel supporting device comprises a door-shaped support frame, an arched support frame, a carbon monoxide concentration sensor and a carbon steel reinforcing layer. The carbon steel reinforcing layer is arranged in the side wall of the arched support frame, a polytetrafluoroethylene corrosion-resisting layer isarranged on the outer side of the arched support frame, the door-shaped support frame is arranged at a central position in the arched support frame, hydraulic jacks are fixed between the door-shaped support frame and the arched support frame uniformly, the output end of the carbon monoxide concentration sensor is electrically connected with the input end of a single chip microcomputer through a wire, and the output end of the single chip microcomputer is electrically connected with the input end of a buzzer alarm through a wire. The high-stability tunnel supporting device has the advantages that a mounting base, a first ground pile, a second ground pile and a shock-absorbing spring are mounted, and accordingly, the high-stability tunnel supporting device is easily fixed into a soil layer;the first ground pile and the second ground pile are provided with barbs, so that the high-stability tunnel supporting device is inserted deeply and not easy to collapse.

Description

technical field [0001] The invention relates to the technical field of support devices, in particular to a tunnel support device with high stability. Background technique [0002] Tunnel is an engineering building buried in the ground, and it is a form of human use of underground space. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, and mine tunnels. The structure of the tunnel includes two main buildings and auxiliary equipment. part, the main building is composed of the tunnel body and the tunnel door, and the auxiliary equipment includes car shelters, fire-fighting facilities, emergency communication and waterproof and drainage facilities. The long tunnel also has special ventilation and lighting equipment. The excavation disturbance of the tunnel will cause relatively large Large surrounding rock deformation, if the support measures are not in place, the surrounding rock deformation may exceed its allowable range, and in severe cases, ...
