Abstract

The invention discloses an environmentally-friendly fresh air system for a tunnel. The system comprises a fresh air duct. An air intake passage is arranged in the middle of the fresh air duct, both sides of the fresh air duct extend toward the outside of the tunnel, air intake passages on both sides of the fresh air duct are closed, and a one-way inlet valve is arranged on the upper end surface ofthe outer protruding end on each side. Two sides of the fresh air duct are respectively provided with a pipe joint, a hose with deformation recovery capability is installed in each pipe joint and isperpendicular to the middle of the fresh air duct, and the upper end surface of each hose is provided with an air outlet pipe extending toward the road surface, and a one-way outlet valve is installedin each air outlet pipe. No power source is adopted, the complete environmentally-friendly fresh air system is adopted, fresh air exchange between the inside and the outside of the tunnel is achievedby means of passing vehicles, dust can be reduced fast, and the effect of once for all can be achieved.

Description

technical field [0001] The invention relates to a fresh air system, in particular to an environment-friendly fresh air system for tunnels. Background technique [0002] When the road passes through the mountain, a tunnel will be opened on the mountain. If the mountain is deep, the length of the tunnel is often very long. At this time, a large number of fresh air systems must be installed in the tunnel. The existing fresh air systems all use The ventilation method of the fan, this kind of fan needs to be connected to the power supply when it is in use, and in order to continue to ventilate, the fan needs to be connected to the power supply all the time, so in the long run, the accumulated lighting loss of these fans is amazing, how to set up a once and for all The environmentally friendly fresh air system is a technical problem that needs to be solved urgently. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an e...
