The history of building a pontoon in China is very long. In the 8th century BC, "The Book of Songs, Daya, Daming", it was stated that Zhou Wenwang, a wife of Zhou Dynasty, set up a pontoon on the waters of the sea. It has been three thousand years since today, and it is the earliest record of building a pontoon. . It is more than five hundred years old than the ancient Greek historian Herodotus. When the Persian king Darius invaded Greece, the world's first pontoon built on the Bosphorus. According to future generations' research, the pontoon was a rare thing. The Zhou Dynasty ceremonies stipulated that only one person can be used, and it should be removed immediately after use. During the Warring States period, "the ritual collapsed and broken", only the rules of the "Tianzi" on the pontoon also collapsed.
By the Han and Tang Dynasties, the use of pontoons in China has become increasingly common. For thousands of years, the built pontoons are difficult to count. In many areas, before building a permanent bridge, it is always necessary to build a floating bridge in order to explore and understand the water conditions, and then to find a suitable permanent bridge type. The Luoyang Bridge mentioned above is an example. According to rough statistics, nearly 20 large pontoons have been built on the Yangtze River and the Yellow River, most of which are military pontoons.
In the spring and autumn period of 541 BC, Qin Jinggong’s mother’s son, the son of the son, was killed by Qin Jinggong’s wealth because of his excessive reserves. He took the pontoon on the Yellow River near Linjin in Shanxi Province today. "The wealth of this fled to Shaanxi from today's Shaanxi, this is the first Yellow River Bridge.
The first Yangtze River pontoon was built in the 11th year of Jianwu (AD 35). The Emperor Guangwu of the Eastern Han Dynasty fought against the military separatist Gong Sunshu in Sichuan. Gong Sunshu used the danger between Jingmen and Yichang County, Hubei Province. The terrain, set up a pontoon, that is, Jiangguan pontoon, to cut off the waterway traffic of Emperor Hanguang. Later, the Navy of Emperor Hanguang used the wind to set fire to the fire.
The Tianjin Bridge, built in Luoyang, Henan Province in the first year of the Great Day (605), was the first pontoon bridged by chains. Li Shimin of Tang Taizong made a poem, four of which were "temporarily low-pitched, high-sounding, shocked, water-swaying, and cable-to-dew", which was used to describe his riding over the pontoon. On the bow of the ship, the ostrich pattern that is good at fighting the wind and the blossoming brocade on the cable sway the turbulent scene on the river waves.
Because the floating bridge floats above the water surface, the construction of the fixed structure is different. Previously only for convenience, use a boat to build. The current construction needs to have a certain visual effect. It has both practical functions, beautiful appearance, and even a pontoon for the landscape. Guangxi Bodun builds a practical and landscaped pontoon, with railings, lights, etc. to create a variety of pontoon views. It is assembled by using floats of different colors, and transforms various shapes according to the actual environment. It adopts the most environmentally friendly raw materials, and the products have reached the standard of food packaging and have no pollution to water quality. From design, production, construction, to after-sales "one-stop" service. Suitable for all water environments. The small pontoon that only walks away can float up and down with the water and feel the joy of walking on the water. The medium and large pontoons that pass through the car can be matched with steel frames and steel plates to achieve a smooth and safe demand.
The Bodhi uses the piling, anchoring and other means to fix the pontoon on the river. It can also be removed under special circumstances and installed separately. Convenient and fast, high economic efficiency.
The pontoon Xiangzi Bridge is located outside the east gate of Chaozhou Ancient City and spans the Han River. It was built in the 7th year of the Song Dynasty (1171). It is one of the four ancient bridges in China, which is known as Zhaozhou Bridge, Luoyang Bridge and Lugou Bridge. It is known as "one of the four ancient bridges in China." The earliest open and close bridge in the world."
