Why do high-speed rail bridges have to be hollow in the middle, so that they are not afraid of bridge collapse? I know today

Now that the technology in our country is getting better and better, my transportation has increased in many ways. Many things in our daily life need some tools to help us complete. And the main tool is our bike. Its use brings us a lot of convenience and makes it more convenient for us to travel. Invisibly, this has brought very convenient benefits to our lives. Now any development changes with people's needs, so everyone has more things to contribute to the society. Some people say, Laziness is the source of all creation. From the beginning, if people were going to go far, they had to go to the back, there were all kinds of animals that pulled people where they wanted to go, but then there was the evolution of cars with all kinds of wheels, and now there are a road to Rome.

Now, people can go anywhere they want without much blowing power. The way a lot of people go out now is by bus, bicycle or self-driving, it will be a long way - you will choose plane or high-speed rail...because only transportation they can go very far. In China, there is also a very special means of transportation - high-speed railway, which can quickly reach various cities and regions. But it is not a mode of transportation available to all countries. We're talking about high-speed rail now. What is the high-speed rail? Today I will tell you about the formation process of high-speed rail. In fact, one of the designs of high-speed rail is strange. As we all know, the number of passengers on the high-speed rail, plus the weight of the carriage itself, is believed to be around tens of thousands of tons. Therefore, in the event of a dangerous accident, there is a great risk of damage, and in addition to this, the driver also encounters this situation and also crosses the bridge.

If the bridge is in danger, knowing the consequences is almost unthinkable. The quality of the bridge is very important. The high-speed rail bridges are designed to be hollow. From the outside, they may be solid. Because it is a whole, there will not be any cracks or other problems. The same is true for bridges. We can use some methods to strengthen them, such as concrete pouring technology. These techniques are more commonly used. But it's actually hollow inside, and one might think it's carrying such a heavy load. If it is hollow, how much pressure should it be able to withstand? Therefore, we say that the structural strength of hollow bridges is not high. And there are many problems to be solved in the actual construction. For example, there are problems with concrete pouring. Isn't it easy to be dangerous because we know that a lot of times bridges are made of concrete. Therefore, on this issue, I think it is still necessary to ensure good quality, and do not let some substandard products enter the market. I personally think this is a key. For example, if he falls after being overwhelmed by this force, the opposite is true. It's safer if it's hollow. If she doesn't have time, she's better able to handle stress. If it's solid, it's heavy enough on its own, and then there's the car and passengers to bear. Dozens of tons of weight can lead to dangerous accidents.

Since a hollow is safer than a solid, it can be hollow, and it is actually hollow, and workers can check the hollow at any time to make sure Joe is in good shape and repair it in time so problems can be found, rather than waiting for the bridge to come down. And when the bridge is made, the whole bridge is poured with reinforced concrete, so that cracks and deformation are not easy to appear, and the quality is very good. If you add some other advantages, it is more economical! So making it solid is like scrap material and it's safe. Making it hollow is good for everything, saves money and puts everyone at ease. When the high-speed rail bridge is solid, what else will you think of? What do you and the construction workers want to say?
