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.
