Problems solved by technology

[0003] In the existing tunnel ventilation system that is convenient for construction, whether it is an active ventilation system or a passive ventilation system, it is necessary to arrange ventilation ducts for each tunnel body, which makes the construction of the tunnel difficult and requires a large amount of construction
And because there are certain requirements for the arrangement position of the ventilation openings of the ventilation ducts, a large number of ventilation ducts will increase the difficulty of arranging the positions of the ventilation openings

Abstract

The invention discloses a tunnel ventilation system convenient to construct. The tunnel ventilation system convenient to construct is characterized by comprising two parallel tunnel bodies (1), wherein a soil base layer (5) is arranged on the tunnel bodies (1), a middle partition wall (2) is arranged between the two tunnel bodies (1) and disposed in the length extending direction of the tunnel bodies (1), a ventilation cavity (3) is formed in the upper end of the middle partition wall (2) and disposed in the length extending direction of the middle partition wall (2), and a plurality of ventilation pipelines (4) are arranged on the upper end face of the ventilation cavity (3). The tunnel ventilation system convenient to construct has the advantages that the defects in the prior art can be overcome and the structural design is reasonable and novel.

Description

technical field [0001] The invention relates to a convenient construction tunnel ventilation system, which belongs to the field of tunnel ventilation. Background technique [0002] In the tunnel, the driving vehicles will continuously emit harmful exhaust gas and smoke. When the concentration of harmful exhaust gas and smoke exceeds a certain value, it will cause harm to the drivers and passengers, affecting their health and driving safety. Therefore, maintain a good air condition in the tunnel It is a necessary condition for driving safety, and the purpose of ventilation is to reduce the harmful gas or pollutants in the tunnel to below the allowable concentration, so as to ensure the safety and comfort of driving, which is an important criterion for the service level of the tunnel. [0003] In the existing tunnel ventilation system that is convenient for construction, whether it is an active ventilation system or a passive ventilation system, it is necessary to arrange vent...
