Problems solved by technology
[0003] Existing support devices for tunnel construction generally need to be connected and constructed according to the size of the tunnel, the structure cannot be adjusted, and cannot adapt to tunnels of different sizes. The force detection device, the surrounding rock structure in the tunnel is difficult to determine, the pressure on the support device may change at any time, and the bearing status of the support device cannot be known in time. When the structural bearing value of the support device is exceeded, serious tunnel collapse and other serious Accidents, low structural bearing capacity and safety

The invention discloses a support device with a monitoring alarm function for tunnel construction, and relates to the technical field of tunnel construction. The support device particularly comprisesa sleeper and a bottom plate. A track is fixed above the sleeper, and a drive wheel is arranged above the track. A motor is connected to the inner side of the drive wheel, and a traction seat is disposed above the motor. The front side of the traction seat is provided with a connecting frame. A chassis is arranged below the bottom plate, and the bottom plate is located at the rear side of the connecting frame. A hydraulic support column is disposed on the left and right sides of the chassis respectively, and a support leg is connected below each hydraulic support column. A support frame is disposed on the outer side of each support leg, and a roller is mounted on the outer side of each support frame. The whole support device is moved by means of a translation structure formed by the rollers and the track. The rollers are symmetrically arranged relative to the bottom plate, and the device moves on the track through the rollers, and the flexibility of the device can be improved.
Description
technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a support device with a monitoring and alarm function for tunnel construction. Background technique [0002] Tunnels are engineering buildings buried in the ground, and are a form of human use of underground space. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, and mine tunnels. When tunnels pass through weak and broken surrounding rock, excavation disturbances It will cause large deformation of the surrounding rock. If the initial support is not implemented in time, the deformation of the surrounding rock may exceed its allowable range. The support structure used in tunnel construction must be strong and reliable to ensure the safety of tunnel construction. [0003] Existing support devices for tunnel construction generally need to be connected and constructed according to the size of the tunnel, and the structure cannot be adjust...
