INTRODUCTION:

Nanning Bridge Inspection Vehicle Rental Xinyue Bridge Free Consultation Hotline 135-0000-3760. The main form of Ms. Fang's stone bridge is stone arch bridge. According to research, stone arch bridges appeared in China during the Eastern Han Dynasty (AD 25-220), such as the unearthed Eastern Han Dynasty portrait bricks engraved with arch bridge figures. Zhao Zhouqiao (also known as Anji Bridge), built from 605 to 617 AD, with a net span of 37 meters, is the first open-shouldered arch with lower abdomen arch on the main arch ring. The arch rings and piers of ancient Chinese stone arch bridges are generally thin and light. For example, they were built in baodai bridge from 816 to 819 AD, with a total length of 317 meters, thin piers and flat arches, and exquisite structure. In Roman times, there were many arch bridges built in Europe. As early as 200 BC ~ 200 AD, eight stone arch bridges were built on the Tiber River in Rome, among which Fabrizio Stone Arch Bridge was built in 62 BC, with 2 holes, each with a span of 24.4 meters. In 98 AD, Spain built the Al Bridge, which is 52 meters high. In addition, there are many stone arch waterway bridges, such as the Garde Diversion Bridge existing in France, which was built in the 1st century BC. The bridge is divided into 3 floors, with 7 holes in the lowest floor and a span of 16-24 meters. Arch bridges in Roman times were mostly semi-circular arches with spans less than 25 meters and piers.
