Ancient ChinaBridgesThe craftsmanship is exquisite, such as that of the Sui DynastyLuoyang BridgeIt has been preserved for more than 1,000 years and has stood still today. Since ancient times,BridgesIt plays an important role in the construction of infrastructure in China, connecting mountains, rivers, lakes and seas, making it convenient for people to travel and promoteEconomyDevelop. However, with the continuous advancement of modernization,BridgesThe construction is also changing with each passing day, highTechnologyThe application of machinery has improved the efficiency of the construction period, but the rationality of the design scheme and the guarantee of construction quality have become the key.
From antiquityLuoyang BridgeTo today's modern infrastructure, the super high level of Chinese craftsmen is inBridgesThe field of construction is fully demonstrated. The ancient bridge has survived the baptism of time and can still be used safely after continuous repair and maintenance, which bears witness to the craftsmanship and infrastructure capabilities of ancient China. And modernBridgesAlthough with the help of highTechnologyMachinery, but still faces many challenges, the key is reasonable design and quality assurance.
The Tuojiang Bridge is located in SichuanJian YangIt was built in the 60s to facilitate the travel of residents on both sides of the Neijiang River. Although it was caricatured as the "ugliest bridge" at the beginning of its construction, after more than ten years of testing, the bridge was recognized by local residents as strong and reliable.

Experts are divided on the safety of the Tuojiang Bridge.

In the end, the experts who advocated blasting gained the upper hand, leading to the decision to blast the Tuojiang Bridge. However, the blasting process took on an unheard of situation.
Holes were drilled, explosives were planted, and the first blasting failed to knock down the bridge. Experts said that the amount of explosives was insufficient, so a second blast was carried out, but even though the amount of explosives was increased to 800 kilograms, the bridge remained unmoved. The audience was shocked, calling these experts pseudo-experts. The experts' misjudgment led to the destruction of the Tuojiang Bridge for no apparent reason, wasting the finances and the reputation of the experts.
After verification by the higher authorities, it was confirmed that the bridge structure was still usable. After state repairs, the Tuojiang Bridge was retained and continues to provide convenience for local residents.
