Abstract

The invention discloses a tunnel construction ventilation monitoring system, comprising an upper monitoring machine arranged in a remote monitoring room, a handheld mobile terminal carried by tunnel ventilation monitoring personnel, a ventilation state monitoring robot which can move front and back in a construction tunnel, a sensor mounting rack installed on the inner side wall of the construction tunnel, and a ventilation state detection device which detects ventilation states in the ventilating duct of the construction tunnel in real time. The ventilation state detection device is installed on the sensor mounting rack. The sensor mounting rack is on the front side of the air supply outlet of the ventilating duct. The ventilation state monitoring robot communicates with the upper monitoring machine, the handheld mobile terminal, and the ventilation state detection device in a wireless communication manner. The system is simple in structure, rational in design, simple in use and operation, and good in use effect. After blasting, the system can monitor distribution conditions of fume and harmful gas on a tunnel face, and monitor the ventilation state of the tunnel ventilating duct in real time.

Description

technical field [0001] The invention belongs to the technical field of tunnel ventilation construction, and in particular relates to a tunnel construction ventilation monitoring system. Background technique [0002] At present, the tunnel construction ventilation at home and abroad mostly adopts the pipeline press-in ventilation method, and an axial flow fan is installed outside the tunnel entrance. The fresh air is sent to the tunnel excavation face, and the dirty air in the tunnel is expelled out of the tunnel along the excavated tunnel body under the squeeze of the fresh air sent into the tunnel. When the tunnel is long, multiple axial flow fans are used in parallel and in series to increase the air volume and air supply distance. In the actual construction process, once the flexible air duct in the tunnel is installed, its position will not be easily moved, and the flexible air duct is usually arranged in the middle and upper part of the side wall of the tunnel, so that...
