Description
Technical field
The present invention relates to construction equipment technical field, specially a kind of constructing tunnel ventilation device.
Background technique
In the constructing tunnels such as railway, highway and city underground engineering, ventilation is indispensable sport technique segment, in machinery
It is turned into the case of industry, divulges information and supply fresh air for in-cavity construction place, exclude dust and various toxic and harmful gas, create good
Good work situation, ensures the health and safety of construction personnel；Meanwhile ventilation is also that the electromechanical equipment in tunnel is maintained normally to transport
Capable necessary condition.
For various tunnels, usually the arrangement and method for construction to entire engineering and Design of Construction Organization are risen not for ventilation
Negligible effect, existing draft type have gravity-flow ventilation and Longitudinal Ventilation, and gravity-flow ventilation refers to the vapour by passing through in tunnel
The piston effect of vehicle and natural wind action, pernicious gas and flue dust are excluded out of tunnel.Longitudinal Ventilation is from a hole
Mouth introduces fresh air, in such a way that another hole decontaminates air.
Gravity-flow ventilation the problem is that, be limited to the size of vehicle flowrate in tunnel, and the unstability of natural wind and
Complexity will affect the exchange of the air-flow in tunnel；Longitudinal Ventilation the problem is that, air pollution degree is from entrance to outlet
Fang Yixiang is linearly increased, and inlet pollution concentration is minimum, and survey pollution concentration is big in outlet, and meeting fire situation will lead to exit
Concentration is high, and smoke evacuation is inconvenient.
Summary of the invention
The purpose of the present invention is to provide a kind of constructing tunnel ventilation devices for effectively improving ventilation effect.
Constructing tunnel provided by the invention ventilation device includes the first ventilating pipe component, and the first ventilating pipe component includes the
