Long-distance trains provide water 24 hours a day. Where does the water come from? Where does the used water and excrement go?
There is no water pipe on the train , because there are water pipes in the house , and there are water pipes in the city , how is it possible to have a 24-hour supply of running water ? This requires us to know which water points are on the train. For example, boiled water is used in toilets, restaurants, and trains; tap water is also used in kitchens and bathrooms. But why isn't tap water used on trains? Where does the hot water in heaters, sinks , toilets , trains come from ?
In order to give passengers a better ride experience, the train stores a certain amount of water on the roof of each carriage before departure . When the train leaves the station, the amount of water left in the car is used to wash off any remaining dirt on the underbody and floor. This not only saves a lot of water resources but also reduces waste pollution. At present, this technology is mature and widely used. There is said to be enough water in the cistern at the top of each car to hold passengers for more than 10 hours , which is more than enough for only****many need to add water once on the initialplatform Solve the water problem .
So , assuming the journey time is more than 10 hours , how to solve the passenger
The answer is very simple. Every time the trainstops at a fixed platform , it can be replenished with special special water filling equipment . In the case of not particularly advanced technology , it is usually supplemented by artificial water , which means that many platforms work Personnel will bring buckets to the roof of the car to refill .
With the development of science and technology , the filling and the outdated manual irrigation methods have been eliminated and replaced by various pipelines. This kind of water pipeline is to use the water flow to push the sprinkler for sprinkler irrigation. Compared with traditional irrigation methods, it has the following advantages: 1. High efficiency. Due to the high-pressure water jet technology, the work efficiency is very high. 2. Save time and effort. After the train stops , open the water inlet on the side of the train, insert a high-pressure water gun, and the water storage tank can be filled within a few minutes.
Despite the change in how the water is fed , workers are still working to ensure that the high-pressure water pipes are properly connected to the outlet and are working 24 hours a day during the minutes when the trains arrive at the station . And for these jobs, if not taken seriously, it will affect people's health and safety. In addition, many areas are experiencing water shortages due to dense urban populations and increasing water demand. Therefore , when we take the train**,** we must pay attention to saving water resources and must not waste it blindly.
Previously**, the** reporter interviewed the staff of several railway stations of Sheung Shui workers , and the interview results were very touching .
For example, a Shangshui worker at Beijing South Railway Station once said that it takes at least 15 minutes to add water to the train, and it takes a long time or even 400 meters to drag a heavy water pipe. It is often very hard work to walk more than 10 kilometers in a day. .
Sheungshui workers at the Tianjin station said their clothes were barely washed and were sometimes doused in tap water before the sweat dried. And now the clothes they wear have all used new environmentally friendly materials. “I wear these to work every day and I feel very comfortable. The weather is nice in summer and the risk of catching a cold is low, but in winter their trouser legs and gloves are often frozen into various shapes after getting wet, and their bodies are like knives As icy cold.
There is also the Shijiazhuang Sheung Shui team. It is said that 90 people work on 137 trains every day. This may not sound like much, but a train usually has dozens of trains that need to be shuttled, not including those who fill up the oil halfway. train. I don't think everyone will forget that it was a winter morning. When all the people were still immersed in the cold, our class had already started to work on the water. But no matter how hard and tired they were, the staff didn't leave their posts because they wanted passengers to have a cup of hot water and enough water on the train.
Generally speaking, 216 kg of water should be added to each carriage. The plumbers on the train need to add water to about 6,000 cars every day, equivalent to 130 tons. So, where did all this water go when it was added to the car?
When water is injected into a train through the station's upper intake, there are usually three places to go:
- For passengers to drink instant noodles.
The station does not pour hot water on the train. The boiling water we usually use on the train is generally heated to 100 degrees Celsius with special heating equipment, and then provided to passengers. But this is not a completely scientific way. Because different countries and regions have different requirements for trains. Most of China's railways are high-speed railway lines with a speed of more than 300 kilometers per hour. Older trains were generally heated with coal, while some more advanced trains are now heated with electricity, which is more thermally efficient and safer.
Second, the water in the washbasin and toilet.
This part of the water does not need to be heated and can be used by pouring the water in the tank directly into the corresponding pipe. If you need to use water, you can turn on the tap or other water-saving facilities to use it, which not only will not waste water resources, but also avoid water pollution. 3. Saving water starts from life. To develop good habits in daily life. such as saving water. There is no water inlet device on the train that can be recycled, so the water sources of the washstand and toilet are clean tap water, and people should pay attention to saving water in the process of using it.
Third, the attack train itself runs.
The water injected into the train is not only used by passengers and staff on the train, but also partly used to meet the running needs of the train itself. This is what we often call "water", also called "energy". It is a precious natural resource. From a theoretical point of view, water should be inexhaustible, but the actual situation is not so simple. Water is limited! Just as cars need water to prevent overheating and overloading, so do trains, but this part of the water consumption is relatively small and can be ignored.
In addition, there are concerns about safety and hygiene on the trains. They say that water from toilets and hand basins on trains can be treated and recycled, but this theory is actually untenable. Because on trains, the water in toilets and sinks flows through pipes instead of being drawn directly from the toilet by a pump, which is obviously unscientific. actually it is a kind of misunderstand. In fact. Not to mention the possibility of a water recirculation system on the train, as the cost of recirculating the water is higher than changing the water alone, and is completely unnecessary.
Therefore, the wastewater produced by trains can usually only be directly discharged into the railway, or collected and centrally treated by other related equipment after the train arrives.
It should be noted that the water from the washstand on the train is not directly drinkable, because it is the tap water used in our daily life, but the hot water on the train is optional, because the hot water in the car wash is generally After heating and processing, after disinfection, it can fully meet the standard of direct drinking.
In theory, there should be enough water on the train that passengers can use it freely and there should be no shortage of water, however, some people should also experience a stop on the train, and people should be aware of this unexpected situation.
