Problems solved by technology

The traditional method has some common disadvantages, that is, it is greatly affected by the construction of tunnels and underground projects, and it cannot be dynamically ventilated according to the concentration of harmful gases in the tunnel, and the fixed air supply volume cannot dilute the concentration of sudden harmful gases in tunnels and underground projects. poses a great threat to the health and safety of construction workers

Abstract

The invention discloses an intelligent ventilation monitoring system suitable for the construction period of a tunnel and underground engineering, and a method. The intelligent ventilation monitoringsystem comprises a collecting module and a controller. The collecting module is configured to receive monitoring data of the air environment nearby a ventilator and transmit the data to the controller. The controller is configured to judge whether the dust and harmful gas allowed value is met or not according to the on-site monitoring data and conduct corresponding pre-warning, the rotating speedof the ventilator is adjusted according to pre-warning information, accordingly, the ventilation quantity in the tunnel is changed, and real-time ventilation control is achieved. The full-automatic real-time feedback monitoring system is adopted, real-time dynamic ventilation in the tunnel, an underground engineering tunnel and the undergrounding engineering can be achieved, efficient environmentprotection is achieved, and the difficulties that the timeliness of suction-type ventilation of the tunnel and the underground engineering is poor, and the air supply volume is fixed are solved.

Description

Technical field [0001] The invention relates to a ventilation intelligent monitoring system and method suitable for tunnel and underground engineering construction period. Background technique [0002] Hazardous substances are generated during the construction of tunnels and underground projects. This includes not only the gas generated after blasting, but also the harmful gas contained in the tunnel itself. In order to create a good working environment, ensure the health and safety of construction workers, and ensure the progress of the project, it is necessary to provide good ventilation for the construction site in the tunnel, change the chemical composition of the air in the tunnel and underground projects, and reduce the concentration of harmful gases. [0003] In the construction period of traditional tunnels and underground projects, suction ventilation is generally adopted. The suction pipe inlet of the ventilator is close to the working surface, and the smoke is directly s...
