Is it because of thermal explosion that a bridge deck in Nan 'an, Fujian burst and arched?

A bridge deck in Nan 'an, Fujian Province burst and arched, which felt like it was caused by heat explosion!

The first bridge in Nan 'an, Fujian suddenly burst and arched. Afterwards, the police cordon was set up locally. The preliminary investigation shows that the cement slab on the bridge deck arches due to the influence of high temperature. At present, the bridge has been blocked. It's really hot this year, reaching a new height! Quanzhou, Fujian Province, according to the local meteorological observatory, there are 30 towns and villages in Quanzhou today that exceed 40℃, and the highest temperature in some areas can reach 42.7℃. In the afternoon, the bridge deck of a local village burst due to the hot sun. The bridge monitoring just recorded this thrilling scene.

It is understood that the bridge was built in 1993, which is a stone arch bridge and a cement pavement; After the incident, the bridge maintenance personnel immediately went to check and pulled up the warning line. According to preliminary investigation, the cause of the incident is that the bridge deck cement slab is affected by high temperature, and the expansion joint expands with heat and contracts with cold, arching; It's really hot in summer, but the arch on the bridge deck should be more than hot, right? It is also possible that there is a design defect. The bridge deck explosion is related to the recent high temperature weather. As the local temperature rises, the bridge deck can't bear its heat, so there are no casualties.

The weather is really high all over this year, and the temperature is also very high this summer. I feel that I can only spend this summer in an air-conditioned room. The temperature in Fujian is also very high. Recently, a bridge deck in Nan 'an, Fujian Province burst and arched, most likely due to the hot weather. The bridge burst and arched, it must be because of the hot weather, and then it was exposed to the sun. There were also some incorrect bridges when building the bridge. Generally speaking, the biggest reason is exposure.

This year is really, really hot. Whether in Fujian or Jiangxi, the temperature is very high, and few people go out to work. But here I want to talk about volunteer workers, especially traffic police, sanitation workers and takeaway brothers. Their hard work in the hot summer really deserves our admiration.
