The excavator brother said to go to a village to work, the customer asked to dig the soil next to the bridge hole to pile a round arch shape, the villagers widened the bridge deck and then dug it.
I saw that after the villagers laid a layer of wooden planks along the arch under the bridge, they began to smear cement and pile up large stones. Seeing the situation, they were all confused, not even a steel bar, and I sincerely doubted that the bridge was repaired and dug up the mound below and collapsed directly.
I didn't expect the teacher who piled up the stones to say that there was no problem, and the bridge next to it was built with stones. It is much stronger than the reinforced concrete poured bridge, and the service life is longer, and the ZhaoZhou Bridge is still alive for more than a thousand people.
The Daoists were combined with square stones, all of which were inlaid with each other, but not round stones of different sizes. I think this bridge is a bit of a hole, so I want to ask if the mound under the hollowing out after the completion of the stone bridge will not collapse?
Hahaha, we see this wave of operations only want to say that this bridge will definitely not collapse. It is worried that this cement will crack or even fall off after a long time, and some unforced stones will fall off along with it. The Zhaozhou Bridge does not use cement, and the shape of each stone is exquisitely carved out, and finally inlaid into a whole, and there is no comparison with cement.
In fact, as long as this bridge is not crossed by heavy trucks, the general tricycle is certainly no problem. If you take the truck, it is still recommended to build a reinforced concrete structure more reliable, then the cost can be high, you must also find a professional construction team to build.
