For in the existing Tunnel Ventilation System for facilitating construction in the prior art, either active ventilation systems or quilt Dynamic ventilating system is required to arrange ventilation shaft for every tunnel body, and such difficulty of construction for making tunnel is higher, construction volume It is larger.And since the position of the ventilation opening of ventilation shaft has certain requirement, the quantity of ventilation shaft is more to be will increase The deficiency of the difficulty of vent position arrangement, the present invention provide a kind of Tunnel Ventilation System for facilitating construction.
In order to solve the above technical problems, the technical solution adopted by the present invention is that, a kind of Tunnel Ventilation System facilitating construction, Including two tunnel bodies disposed in parallel, it is soil property base above tunnel body, middle part partition wall is provided between two tunnel bodies, in Portion's partition wall is arranged along the length extending direction of tunnel body;The upper end of the middle part partition wall is provided with ventilation housing, ventilation housing edge The length extending direction of middle part partition wall is arranged;Several ventilation shafts, ventilation shaft are provided on the upper surface of the ventilation housing Uniform intervals are arranged on ventilation housing extending direction;The two sides of the ventilation housing are provided with several ventilation exhaust outlets, ventilation The top of pipeline is connected with ventilation opening, and several aided filter pipes are provided on ventilation shaft, and the top of aided filter pipe is set to In soil property base, the top of aided filter pipe is provided with sand prevention strainer.
In the technical solution of the application, the ventilation shaft that every tunnel body is separately provided is changed to by ventilation housing and ventilation The form of tube fit carries out air draft by being set to the intracorporal ventilation exhaust outlet in every tunnel on ventilation housing, so only One row's ventilation shaft need to be set, and the quantity of ventilation shaft reduces compared with the existing technology, and the technical solution of the application In ventilation shaft can only one row of setting without be arranged it is two rows of so that it is convenient to the position of ventilation shaft outlet setting.
Optimization, the above-mentioned Tunnel Ventilation System for facilitating construction, the ventilation opening includes a cabinet, the upper surface of cabinet On be provided with cover board, cover board is equipped with several air holes, is provided with waterproof ventilated membrane in air hole.
Optimize, the above-mentioned Tunnel Ventilation System for facilitating construction, the junction of the cabinet and ventilation shaft is provided with anti- Water ventilated membrane;Water-permeable pipe is connected on the lower end surface of the cabinet, the end of water-permeable pipe is set in soil property base.
Optimize, the above-mentioned Tunnel Ventilation System for facilitating construction, is provided with Afforestation Landscape cabinet on the cover board.
Optimization, the above-mentioned Tunnel Ventilation System for facilitating construction, be provided on the lower end surface of the cabinet it is several catchment it is recessed One end of slot, water-permeable pipe 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, cabinet is set under Afforestation Landscape, when gas discharges in this way in tunnel, tunnel is filtered by the soil property that green panorama is seen The gas inside given off, so that the air pollution concentration of gas discharge reduces.
Since cabinet to be set under Afforestation Landscape, when Afforestation Landscape is watered, water can flow into tunnel along cabinet, In order to solve this problem, it is provided with several catchment recess on the lower end surface of cabinet in the technical solution of the application, catchments recessed The lower end surface of slot is lower than the lower end surface of cabinet, and such water can be gathered in catchment recess, and be left to soil property base by water-permeable pipe In layer.
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 for facilitating construction, including two tunnel bodies disposed in parallel 1, it is soil property base 5 above tunnel body 1, middle part partition wall 2 is provided between two tunnel bodies 1, middle part partition wall 2 is along tunnel body 1 The setting of length extending direction;The upper end of the middle part partition wall 2 is provided with ventilation housing 3, length of the ventilation housing 3 along middle part partition wall 2 Spend extending direction setting;Several ventilation shafts 4 are provided on the upper surface of the ventilation housing 3, ventilation shaft 4 is in ventilation housing Uniform intervals are arranged on 3 extending directions;The two sides of the ventilation housing 3 are provided with several ventilation exhaust outlets, the top of ventilation shaft 4 End is connected with ventilation opening, several aided filter pipes is provided on ventilation shaft 4, the top of aided filter pipe is set to soil property base In 5, the top of aided filter pipe is provided with sand prevention strainer.
In the technical solution of the application, the ventilation shaft 4 that every tunnel body is separately provided is changed to by ventilation housing 3 and is led to The form that air piping 4 cooperates, carries out air draft by the ventilation exhaust outlet being set in every tunnel body 1 on ventilation housing 3, this Row's ventilation shaft 4 need to be only arranged in sample, and the quantity of ventilation shaft 4 reduces compared with the existing technology, and the skill of the application Ventilation shaft 4 in art scheme can only one row of setting it is two rows of so that it is convenient to position that ventilation shaft 4 exports without being arranged Setting.
