Description
Technical field
The present invention relates to a kind of Tunnel Ventilation Systems, belong to tunnel ventilation field.
Background technique
In tunnel, the vehicle of traveling can constantly discharge harmful exhaust and flue dust, when the harmful exhaust and flue dust of discharge are dense
Degree will bring harm when being more than certain value to driver and conductor, influence health and traffic safety, therefore keep in tunnel good
Air condition is the necessary condition of traffic safety, and the purpose divulged information is that pernicious gas in tunnel or pollutant are reduced to permission
For concentration hereinafter, safety and comfort to guarantee running car, this is a major criterion of tunnel service level.
Existing Tunnel Ventilation System is divided into active ventilation systems and passive ventilating system.Active ventilation systems pass through fan
Class ventilation equipment realize ventilation, but in the prior art, due to air pollution concentration high concentration at tunnel air outlet, it is difficult to full
Toe ring guaranteed request.If the laying of ventilation shaft by various conditions such as landscape, nearby residents due to being opposed, rule using passive ventilation
The limitation waited is drawn, often is difficult to find suitable installation position again.
Summary of the invention
It is divided into active ventilation systems and passive ventilating system for existing Tunnel Ventilation System in the prior art.It is actively logical
Wind system realizes ventilation by fan class ventilation equipment, but in the prior art, due to air pollution concentration at tunnel air outlet
High concentration, it is difficult to meet environmental requirements.If using passive ventilation, the laying of ventilation shaft due to by various conditions such as landscape,
Nearby residents oppose that the limitation planned etc. often is difficult to find the deficiency of suitable installation position again, and the present invention provides a kind of tunnel
Road ventilating system.
In order to solve the above technical problems, the technical solution adopted by the present invention is that, a kind of Tunnel Ventilation System, including two flat
The tunnel body of row setting is provided with middle part partition wall between two tunnel bodies, and the top of the middle part partition wall is provided with ventilation cabinet,
It is provided with two ventilation shafts on ventilation cabinet, is soil property base above tunnel body；Two ventilation shafts are each passed through soil
Matter base, soil property base top are provided with ventilation opening, and ventilation opening is connect with ventilation shaft；The both ends of the ventilation cabinet are set respectively
It is equipped with supply fan, is provided with air ejector fan in ventilation shaft.
Optimization, above-mentioned Tunnel Ventilation System, the ventilation opening includes a cabinet, is provided with lid on the upper surface of cabinet
Plate is provided with several air holes on cover board, is provided with waterproof ventilated membrane in air hole.
Optimize, above-mentioned Tunnel Ventilation System, the junction of the cabinet and ventilation shaft is provided with waterproof ventilated membrane；Institute
It states and is connected with water-permeable pipe on the lower end surface of cabinet, the end of water-permeable pipe is set in soil property base.
Optimize, above-mentioned Tunnel Ventilation System, is provided with Afforestation Landscape cabinet on the cover board.
Optimize, above-mentioned Tunnel Ventilation System, is provided with several catchment recess on the lower end surface of the cabinet, water-permeable pipe
One end is connect with catchment recess, and the other end of water-permeable pipe is set in soil property base.
The advantage of the invention is that it can overcome the disadvantages of the prior art, novelty reasonable in design.The design of the application
In, by using the mixed form of active ventilation and passive ventilation, cabinet (6) is set under Afforestation Landscape, in this way in tunnel
When interior gas discharges, the gas given off in tunnel is filtered by the soil property that green panorama is seen, so that the air of gas discharge is dirty
Contaminating concentration reduces.
Since cabinet (6) to be set under Afforestation Landscape, when Afforestation Landscape is watered, water can be flowed into along cabinet (6)
In tunnel, be provided on the lower end surface of cabinet (6) in order to solve this problem, in the technical solution of the application it is several catchment it is recessed
Slot (12), the lower end surface of catchment recess (12) are lower than the lower end surface of cabinet (6), and such water can be gathered in catchment recess (12),
And it is left in soil property base by water-permeable pipe (11).
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Specific embodiment
With reference to the accompanying drawing with the specific embodiment technical characterstic that the present invention is further explained.
As shown in Figure 1, the present invention is a kind of Tunnel Ventilation System, including two tunnel bodies 1 disposed in parallel, two tunnels
