Take the analogy of Luoyang Bridge in Quanzhou, not too long.

Luoyang Bridge, the first bridge on the sea, saw this name for the first time and thought it was in Luoyang City, Henan Province. In fact, it is thousands of miles away from Luoyang. It is located at the confluence of Quanzhou Bay and Luoyang River near Quanzhou City, Fujian Province. Luoyang Bridge is the first large-scale stone bridge across the sea in China. Built in 1053, it took six years to complete. Shiqiao 1No. * * is 1200m long and 5m wide, with 44 piers. There are railings on both sides of the bridge. Now there are only 3 1 piers left in the stone bridge, and the length is 1 188 meters. Luoyang Bridge has many innovations in architecture. It adopts "raft bridge foundation", and under the river in the middle line of the bridge, many large stones are used to build piers. The water here is deep and urgent, and the stones will be washed away by the flood after being dropped. 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 quietly at the bottom of the river. In order to unify the piled stones at the bottom of the water so that they will not be washed away by the flood, the bridge builder came up with a wonderful way. There is a mollusk with a shell at the bottom of the sea, named oyster. It has two shells, one attached to a rock or another oyster and intertwined with each other, and the other shell is covered with its own software. 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. The foundation of Luoyang Bridge lasted for more than 900 years, but it didn't collapse, and oysters contributed a lot. This event can be said to be a great creation in the history of architecture. All the stone slabs laid on Luoyang Bridge are more than 65,438+00 meters long, thick and large. It is estimated that each slate weighs twenty or thirty tons. How can such a heavy stone be transported to the high pier? Inspired by the ebb and flow of the tides, the bridge builders adopted the floating method. When the tide rises, craftsmen use rafts to transport stones to the piers, and use the buoyancy of the rising tide to put stones on the piers. More than 300 stone slabs and tens of thousands of stones on Luoyang Bridge were erected in this way. Luoyang Bridge is known as "the wonder of the world", which makes sense. Now there is a plaque at the bridge head in Luoyang, which reads "The First Bridge on the Sea". The completion of Luoyang Bridge has promoted the development of maritime trade and provided valuable experience for the construction of stone bridges in China.
