Tunnel portal condensate water and snow removing system

Abstract

The invention discloses a tunnel portal condensate water and snow removing system which comprises a tunnel and a condensate water and snow removing device installed on the tunnel, the condensate water and snow removing device comprises a fan, a ventilation main pipe, a first ventilation auxiliary pipe, a second ventilation auxiliary pipe, a power source and a controller which are fixedly installed on the inner wall of the tunnel, and an air outlet is formed in an air opening adjusting device. A plurality of humidity sensors and temperature sensors are fixedly installed on the tunnel portal and the inner wall of the tunnel portal, and a plurality of snowfall monitoring sensors are fixedly installed on the outer side of the tunnel. According to the tunnel portal condensate water and snow removing system, an idle high-power fan is utilized for manufacturing the tunnel portal condensate water and snow removing system which is capable of monitoring the tunnel portal condition in real time. The hot air in the tunnel is blown to the inner wall of the tunnel portal and the road surface of the tunnel portal in time, snow falling on the road surface can be blown to the two sides of the road, snow freezing on the road surface is avoided, it can also be avoided that condensate water drips on the road surface to affect automobile driving safety, and the traffic safety of the tunnel portal is effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of tunnel engineering, in particular to a system for removing condensed water and snow at a tunnel opening. Background technique [0002] The tunnel is the throat of the highway, and the space is relatively narrow. In winter, the average temperature of the coldest month is below 0°C, and the extreme temperature is below -20°C. The temperature in winter is low and snowfall is easy. Tunnel opening is the transition position from tunnel to road (or from road to tunnel). When snowfall occurs, there is no snow in the tunnel, and the driving environment is relatively good. At the same time, the temperature inside the tunnel entrance is high, and the temperature outside the tunnel entrance is low. The inner wall of the tunnel opening is easy to freeze, and condensed water drips onto the road surface, which will also cause the road surface to freeze. At this time, drivers and passengers tend to relax their vigilan...

AI Technical Summary

Problems solved by technology

Outside the tunnel, due to snowfall, it is easy to cause snow on the road to freeze, and the road condition is not good.

When driving to the exit of the tunnel, because the driver and passengers cannot quickly and accurately realize the situation, they often continue to drive at a higher speed without reducing the speed, which often leads to traffic accidents.

Once a traffic accident occurs at the tunnel entrance, it will directly affect the passage of vehicles in the tunnel, and easily cause secondary accidents in the tunnel, which will hinder the traffic on the whole line

At present, the treatment measures taken are to sprinkle snow melting agent on the entrance of the tunnel before freezing after snowfall, and extend from the entrance of the tunnel to the inside of the tunnel for about 30m to prevent the snow and water brought into the tunnel by vehicles from freezing. and road conditions, the processing is not timely, and consumes a lot of manpower and material resources
