Description
Technical field
Technical field of tunnel construction is the utility model is related to, Piston Action Wind formula track traffic device is resisted more particularly to one
Case.
Background technology
As track traffic transport power constantly rises, speed is continuously improved, and often implements to shorten running interval to improve train
The measures such as transport power, thus cause tunnel Piston Action Wind constantly to increase, so that the influence produced to equipment in tunnel is increasing.
Piston Action Wind refers to the train in the operation of tunnel high speed, and the air in tunnel can be driven to produce flow at high speed, because
The phenomenon of similar cylinder inner carrier compressed gas, is known as piston effect.When the train of high-speed cruising enters tunnel, the sky in tunnel
Gas was static originally, because of the bang of train, produced high pressure wave, which is propagated (much larger than train driving speed with the speed of sound
Degree), therefore when the high pressure wave of train into tunnel generation is transmitted rapidly toward downstream, the tunnel air that pressure wave is passed on is added immediately
Speed, back wave is produced when pressure wave arrives at downstream tunnels mouth, back wave is transmitted toward tunnel upstream, when the tunnel air of its transmission
It will be accelerated again.The same train tailstock enters tunnel, can produce one suction wave, this strand of suction wave, can similarly make
Air velocity in tunnel.In addition it is subject to the influence of tunnel construction, also may penetrating or change ripple reflecting because of fluctuation
It is dynamic.Produce various fluctuations because train is travelled in tunnel and ramp up in tunnel air in tunnel, make the sky in tunnel
Gas is advanced with train to be shaken, just the piston effect referred to as in tunnel.
Equipment in tunnel will bear the ejected wave punching of the positive pressure and negative pressure produced as bullet train frequently comes in and goes out
Hit, this impact is by positive pressure, negative pressure and the synthesis of vibrations.Influence of the piston effect to the equipment in tunnel, especially
It is that can be destroyed by its lockset, cause breakage for the various device casees for having folding chamber door, Piston Action Wind, after short-term operation, lockset occurs and break
The problem of damage, Piston Action Wind can blow device chamber door open, Solve on site method disunity, such as metal base plate are reinforced, adhesive tape winding
Situation, be made it is lack of standardization, be not easy to operation maintenance personnel operation.
