The three major technical achievements in building Luoyang Bridge are as follows

Three technological achievements in the construction of Luoyang Bridge;

1, raft foundation

The first is the problem of bridge foundation. The most important thing in bridge construction is that the bridge foundation must be stable. At that time, faced with the forgetfulness of workers, many stones were thrown into the sea, but they were all washed away by the flood. In order to solve this problem, skilled craftsmen tried and tried and found a good way. They waited for a calm low tide, and at the same time dispatched a number of ships full of stones and filled the river with stones.

In this way, a bridge foundation 500 meters long and 25 meters wide was built underwater. The long bridge foundation is like a long underwater dragon, lying at the bottom of the river, without worrying about them being washed away by the sea. This construction method is the first time in the history of the world.

2, oyster solid foundation method

Oysters are very fertile and pervasive. Once mixed with stone glue, they can't be shoveled down with a shovel. Craftsmen use this characteristic of oysters to plant oysters on the bridge foundation. Sure enough, within a few years, oysters connected the scattered stones into a whole and glued the scattered stones together.

3, the floating beam erection method

At that time, there was no modern lifting equipment, and the craftsmen who built the bridge were inspired by the tide fluctuation and adopted the "floating girder erection method". At the high tide, they transported dozens of tons of stones piece by piece by boat and slowly laid them on them. Professor Mao Yisheng, a famous bridge expert in China, praised Luoyang Bridge as the first bridge in Fujian.

The origin of the name of Luoyang Bridge:

As early as before the Tang and Song Dynasties, there were Yue people living in Quanzhou. In the early years of the Tang Dynasty, due to social unrest, wars broke out from time to time, which led to a large number of Central Plains people moving south. Most of them moved to Quanzhou and Minnan, mainly from Henan, Hehe and Luoshui. The language family used in Quanzhou and even the whole southern Fujian is called Heluo, which is Minnan dialect.

These Zhongyuan people, with the advanced agricultural technology and experience of the Central Plains, led the local people to reclaim and develop and came to Quanzhou. Seeing that the mountains and rivers here are very similar to the ancient capital Luoyang, I named it Luoyang, hence the name of this bridge.
