Top is supercrust, is respectively arranged with some ventilation shafts at the top of two tunnel bodies, ventilation shaft along tunnel body length side
To arranged for interval；The top of the ventilation shaft is provided with landscape flower bed, and the top of ventilation shaft joins with the bottom of landscape flower bed
It is logical；Filter is provided with the middle part of the ventilation shaft.
In the technical scheme of the application, filter is set at the middle part of ventilation shaft, can so reduce ventilation shaft
The air pollution concentration reduction of discharge, and the discharge of low stain concentration allows that the position of exhaust outlet is entered in more regions
Row arrangement, facilitates the carrying out of constructing tunnel.
Optimization, above-mentioned tunnel ventilation filtration system, the bottom surface of the landscape flower bed is less than supercrust, the top of landscape flower bed
Face is higher than supercrust.
Optimization, above-mentioned tunnel ventilation filtration system, the filter include some filter boxs, filter box it is upper
End and lower end and ventilation shaft UNICOM；The both sides of the filter box are respectively arranged with a pipeline, and pipeline joins with soil property basic unit
It is logical；Nonwoven layer is provided with the interior lower end face of the filter box.
In the technical scheme of the application, two-layer filtering is carried out by filter box and landscape flower bed.In the prior art, soil
There is certain filtration（In surviving in the wild, the filtering of drinking water is carried out using the fabric for being surrounded by soil）, it is particularly wet
The soil of profit, its filter effect is better than dry soil, and soil is more toward deep layer, and its humidity is bigger.The gas of ventilation shaft discharge
Body by soil filtering, its pollution concentration substantially reduces and can reach discharge standard, the arrangement of the outlet of such ventilation shaft
Scope increases, and is arranged during convenient construction.In the technical scheme of the application, the soil in filter box passes through upper strata from pipeline
Soil is pressed into filter box.
Optimization, above-mentioned tunnel ventilation filtration system is provided with some catchment recess on the lower surface of the filter box,
Water-permeable pipe is connected with the lower surface of catchment recess, the other end of water-permeable pipe is arranged in soil property basic unit.
Optimization, above-mentioned tunnel ventilation filtration system, the lower surface of the landscape flower bed is connected with water-permeable pipe.
When Afforestation Landscape is watered, water can be flowed into tunnel along casing, in order to solve this problem, the skill of the application
Water-permeable pipe is provided with art scheme on the lower surface of landscape flower bed, such water meeting water-permeable pipe is left in soil property basic unit.Remaining water
After being diverted into filter box, water is flowed in catchment recess, then flows to soil property again by the water-permeable pipe on filter box
In basic unit.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Specific embodiment
Technical characterstic of the invention is expanded on further with specific embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, the present invention is a kind of tunnel ventilation filtration system, including two tunnel bodies 1 be arrangeding in parallel, two
Middle part partition wall 2 is provided between tunnel body 1, the top of tunnel body 1 is soil property basic unit 5, and the top of soil property basic unit 5 is supercrust 6, two
The top of tunnel body 1 is respectively arranged with some ventilation shafts 3, ventilation shaft 3 along tunnel body 1 length direction arranged for interval；Institute
The top for stating ventilation shaft 3 is provided with landscape flower bed 20, the top of ventilation shaft 3 and the bottom UNICOM of landscape flower bed 20；It is described
The middle part of ventilation shaft 3 is provided with filter.
In the technical scheme of the application, filter is set at the middle part of ventilation shaft 3, can so reduce ventilation shaft
The air pollution concentration reduction of 3 discharges, and the discharge of low stain concentration allows the position of exhaust outlet in more regions
Arranged, facilitated the carrying out of constructing tunnel.
The bottom surface of the landscape flower bed 20 is less than supercrust 6, and the top surface of landscape flower bed 20 is higher than supercrust 6.
The filter includes some filter boxs 7, top and bottom and the UNICOM of ventilation shaft 3 of filter box 7；Institute
