Comprehensive ventilation system for tunnel construction and control method

Abstract

The invention provides a comprehensive ventilation system for tunnel construction, which comprises a ventilator 8 and a first rack 7, and is characterized by further comprising a refrigeration system, a first ventilation system and a second ventilation system, the ventilator 8 is fixedly installed on a top platform of the first rack 7 through a first damping device, the refrigerating system is fixedly installed on a top platform of the second rack 6 through a second damping device, and the ventilator 8 is flexibly connected with the refrigerating system through a negative pressure air pipe. The ventilator 8 and the refrigerating system are mounted on the two racks correspondingly, so that the situation that vibration is transmitted to the refrigerating system during operation of the ventilator, and a refrigerant of the compressor leaks is avoided; the air tightness can be ensured by adopting the flexible connection of the negative pressure air pipe, and the effects of shock absorption and shock reduction are achieved.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a tunnel construction comprehensive ventilation system and a control method. Background technique [0002] The traditional simple press-in ventilation method adopts the method of introducing fresh air to dilute and remove dirty air. With the extension of the tunnel construction distance, a large amount of fresh air needs to be introduced. In summer, the air temperature outside the tunnel is higher than that of the mountain. Traditional ventilation methods send high-temperature outdoor air into the tunnel, which not only does not have a cooling effect, but increases the air temperature inside the tunnel. The demand for fresh air for internal combustion equipment is far greater than that for simple operations. During construction, only when tunnel blasting and slag are produced, there are more internal combustion equipment and a greater demand for fresh air. A quarte...

Problems solved by technology

The demand for fresh air for internal combustion equipment is far greater than that for simple operations. During construction, only when tunnel blasting and slag are produced, there are more internal combustion equipment and a greater demand for fresh air. A quarter of the excavation cycle time, while the traditional ventilation method uses a uniform air volume throughout the excavation cycle, which will inevitably result in waste of fan power and power resources.
