Problems solved by technology
[0002] Some railway tracks are laid in tunnels. When the tunnel is in a low-lying area, it is easy to generate water accumulation, and the railway track is eroded by water accumulation to cause disease, which affects the service life of the railway track, and it is easy to derail when the train is running on the water accumulation track.
At present, although drainage devices are installed in some tunnels, it is difficult to drain water in time when the amount of accumulated water is large, and due to poor visibility in the tunnel, the staff cannot accurately know the situation of accumulated water

The invention relates to the technical field of drainage devices, and discloses a drainage device for a railway tunnel. The drainage device comprises a detection device and a drainage device, whereinthe drainage device comprises a water permeable plate, a first drainage pipe and a water collecting tank arranged at the bottom of the tunnel; water permeable holes penetrating through the water permeable plate are formed in the water permeable plate; the water permeable plate is arranged above the water collecting tank; the water permeable holes are communicated with the water collecting tank; the water collecting tank is further communicated with the first drainage pipe; the detection device comprises a first water level sensor, a control module and an alarm; the first water level sensor isarranged above the water permeable plate; and the control module is electrically connected with the first water level sensor and the alarm. By arranging the detection device, workers can know the situation of water accumulation in the tunnel, and by arranging the drainage device, drainage in the tunnel can be achieved, and train derailment is prevented.
Description
technical field [0001] The invention relates to the technical field of hydrophobic devices, in particular to a hydrophobic device used in railway tunnels. Background technique [0002] Some railway tracks are laid in tunnels. When the tunnel is in a low-lying area, water accumulation is likely to occur. The railway track is eroded by water accumulation and causes disease, which affects the service life of the railway track. Moreover, it is easy for trains to derail when running on the water accumulation track. At present, although drainage devices are installed in some tunnels, it is difficult to drain water in a timely manner when the amount of accumulated water is large, and due to poor visibility in the tunnel, the staff cannot accurately know the situation of accumulated water. Contents of the invention [0003] The purpose of the present invention is to provide a drainage device for railway tunnels, which can know the water accumulation and can also perform drainage. ...
