The degree of transportation development is also one indicator to test whether a country's national strength is strong. Regarding transportation, China has long been at the forefront of the world, especially in the field of bridge construction. It has even been regarded as a benchmark by the world, attracting other countries to follow suit. Generally speaking, there are two standards for bridge construction in the world: the Chinese standard and the European standard. Although these two standards are world standards, the Chinese standards are far more stringent than the European standards, so some European countries want to catch up quickly, but unexpectedly, they make the world laugh.

China's standards are strict because China has put a lot of effort into infrastructure construction, especially some large bridges. At the beginning of construction, these bridges had strict requirements for general vehicles and for some large-tonnage military vehicles to pass safely in special situations or emergencies. Therefore, military standards must also be taken into consideration. The Nanjing Yangtze River Bridge is an example.

The Nanjing Yangtze River Bridge was put into construction in early 1960 and opened to traffic in September 1968. When the bridge was completed, relevant departments specially transferred 118 tanks from nearby military camps to test its quality. These tanks drove across the Nanjing Yangtze River Bridge safely and without damaging the bridge deck, proving that the quality of the Nanjing Yangtze River Bridge is very high. At that time, this incident shocked China and foreign countries. Many countries did not believe that China's infrastructure strength was so strong, so they followed suit one after another to prove that "tanks on the bridge" were just a piece of cake. However, you will know whether it is a mule or a horse after taking it out for a walk.

Within a few years, the Czech Republic built a 600-meter-long large bridge, the world-famous Ruselray Bridge. But this one is famous not because of its good quality, but because of the jokes it makes. To prove that the quality of the Russelai Bridge was better than that of the Nanjing Yangtze River Bridge, the Czech Republic also used tanks to test the quality of the bridge. At that time, the Czech Republic thought the 118 tanks were too few and deliberately added two more. One hundred twenty tanks lined up majestically, waiting to reach the other side of the bridge, but little did they know that they would never reach the other side. The onlookers noticed something was wrong when the tank climbed onto the bridge. Why were there such obvious cracks on the bridge? Is there a problem with the designed bridge deck shape or the quality of the bridge?

At this time, the person in charge also realized something was wrong and immediately ordered the tank to stop moving forward. The tanks on the bridge stopped immediately. There was surprise and disgust among the people, causing the person in charge to "escape" from the scene as quickly as possible. It is said that the Czech Republic invested nearly one billion US dollars to build this bridge, but in the end, it failed even to pass the inspection, which shows its poor quality. Fortunately, everyone discovered the problem in time; otherwise, it might have caused an accident. Later, this bridge was regarded as a counterexample by the international community, and naturally, it became "world-famous."

After the crowd dispersed, the person in charge put his life behind him and decided to go up to the bridge to find out what was happening. As a result, he found 12 cracks in the bridge, which was sad. Initially, the Czech Republic built this bridge not for actual needs but to prove its infrastructure strength. But what they didn't expect was that it turned out to be a historic joke.

The role of PVA fiber in construction

High-strength and high-modulus PVA fiber has important application value in construction projects. Due to its high strength and modulus properties, PVA fiber can reinforce concrete and cement products to increase their tensile strength and durability. In addition, PVA fiber can also be used to reinforce soil and rocks to improve the stability and load-bearing capacity of the foundation.
