A villager said that the stone bridge on the edge of the village was suddenly constructed, and under each arch hole welded I-beam to reinforce the "picture below".
This bridge was built in the 1980s, and it has been gone for decades, and I thought that there was a quality problem with the bridge. Inquired about it and learned that a local enterprise transporting large machinery needs to pass through this bridge, the weight of the machinery plus the weight of the car has a total of more than 280 tons, worried about the bridge collapsed before reinforcing it.
Although the engineering steel reinforced each arch hole, the weight was still pressed on the pier. To know that the original design of this arch bridge is not expected to pass such a heavy vehicle, really worried that this bridge will be crushed, affecting the service life.
Dizzy, we saw this and wanted to ask if there was no other road to go, and we had to go through this stone bridge. Although I don't know what the maximum load-bearing capacity of the original design was, I also felt that the 280-ton car on the stone arch bridge was a bit unreliable.
Don't look at the arch hole to strengthen, but this stone arch bridge, there is still a possibility of being crushed and cracked. It should be known that the life of the stone arch bridge is not comparable to the reinforced concrete bridge, and the Zhaozhou Bridge designed by Li Chun is more than a thousand years old, and the longest life of reinforced concrete is 180 years.
I was really worried that this bridge was crushed out of the internal injury, and when these I-beams corroded and rotted, they collapsed together. Therefore, it is necessary to report to the village chief, sign a contract with the enterprise, and if the bridge is broken, it must be repaired to a new one, instead of reinforcing it with steel. ay!
