When you go out on a trip, have you ever looked up at those high-profile high-speed rail stations?For example, Nanjing Station has a total height of 5996 meters, the highest point of Wuhan Station is 58 meters from the ground, and other high-speed rail stations are not low.
Many people have different opinions about this height of the high-speed rail station.
Some people believe that as the country with the longest high-speed rail mileage in the world, it is natural to build a high-speed rail station higher.
Some people also believe that the reason why China built the high-speed rail station so high is because we pay attention to the appearance and think that the high-profile style is more face-saving.
This conjecture is not unfounded. However, what is the real reason why high-speed rail stations are so high?Is it really just a face-saving project?
In terms of human height, the vast majority of people are less than two meters tall, so is it a waste to build a 60-meter-high high-speed rail station?
From the perspective of the average height of Chinese, the average height of men aged 18-44 is 1697cm, 158cm for women. Although this data is as of 2020, the average height of Chinese people may be **, but even so, this increase is only 1-2cm, and the highest is just over 2 meters.
However, the building height of the high-speed rail station has reached about 60 meters. Considering the difference between the height of the person and the height of the building, it does feel a bit wasteful.
In fact, building the high-speed rail station higher does have some face-saving elements. After all, who doesn't love tall, open buildings?When passengers see such a high-speed rail station, they will naturally feel high-end and magnificent.
However, it would not be accurate to say that the high-speed rail station was built so high for the sake of face.
After all, if it is just for the sake of face, it is completely possible to choose not to build such a high, but to build a platform seven or eight meters high, and then luxuriously decorate the interior, which can also achieve a similar effect.
The main reason why the high-speed rail station is built so high is actually very simpleIt is to prevent people from breathing poorly in the station, feeling stuffy and suffocating. In 2008, a railway station in the south had a suffocation of many passengers due to insufficient floor height in the station.
The train station, the largest amount, especially on holidays, people squeeze each other, all kinds of sweat and foot odor are intertwined, which is simply chilling. If the ceiling height of the room is not enough, the oxygen becomes thinner, and long-term retention can lead to dizziness and difficulty breathing.
In that cramped and cramped train station, many frail passengers fainted from the crowding and lack of breath. At that time, the incident was widely reported, so you can search for it if you are interested.
As can be seen from this incident, the main reason for the construction of the high-speed rail station is to prevent similar tragedies from happening again. Considering the huge population of our country, if the floor height design is not enough, when the ** surges, it may lead to insufficient platforms, and even the queue extends to the outside of the high-speed rail station, which brings great inconvenience to passengers.
Rather than facing subsequent reconstruction and expansion, it is better to design sufficient at one time to ensure the safety of passengers and provide sufficient platforms to facilitate the travel of tourists. In general, it is better to be big and total than small and insufficient, and it is better to waste some in the early stage than to expand in the later stage.
In addition to that,The high-speed rail station was designed to be high, and daylighting was also considered.
Because the high-speed rail station needs to be lit up 24 hours a day, if the floor height is not enough, a lot of electric lighting equipment will be added, which is not only not environmentally friendly, but also not conducive to energy conservation.
On the contrary, the higher ceiling height design facilitates direct exposure to natural light, and the dome design reduces the dependence on light, which is environmentally friendly and energy-saving, killing two birds with one stone.
In addition, the design of a taller high-speed rail station is conducive to ventilation and noise reduction. Because the high-speed rail station is very densely populated, the large space can effectively reduce noise and alleviate the feeling of depression. Therefore, forReduce passenger discomfort and improve comfortThe design height of the high-speed rail station has also been expanded accordingly.
Finally, from the perspective of personnel safety, the high-speed rail station is tens of meters highHelps the air flow well and slows down the spread of viruses and bacteria. Moreover,In the event of a fire or ** accident, the high dome design helps to keep the shock wave awayto minimize the number of personnel and reduce the difficulty of rescue.
Therefore, from the perspective of aesthetics, comfort, safety and environmental protection, high-speed rail stations should indeed be designed to be higher. Especially the core site with a huge volume.
