Floating Bridge
Nov 14, 2018

A pontoon is a bridge that replaces a pier with a ship or a pontoon and floats on the surface of the water. The military pontoon, which is assembled by the military using standard equipment, is called the pontoon bridge. The historical record of the pontoon is early in China. "The Book of Songs, Daya, Daming" records: "Pro-welcome to the shackles, build a boat for the beam", recording Zhou Wenwang Jichang in the 184th BC in the raft bridge. In foreign countries, the Persian Empire Cyrus built a pontoon in Mesopotamia in 537 BC.

"The Book of Songs, Daya, Daming" records: "Pro-welcome to the shackles, build a boat for the beam", and record Zhou Wenwang Jichang in the Pontoon Bridge in 1184 BC. In the eleventh year of Emperor Guangwu of the Eastern Han Dynasty (AD 35), Gong Sunshu set up the Yangtze River pontoon between Yidu and Yichang in Hubei. In the tenth year of Emperor Wudi of the Western Jin Dynasty (274 years), Du Pre set up the Heyang Floating Bridge in the Yellow River near Mengjin, Henan Province, which has been used for more than 800 years. In foreign countries, the Persian Empire Cyrus the Great built a pontoon in Mesopotamia in 537 BC; Zeer I entered Europe in 481 BC and was in Halesville (now Dardanelle). The strait) built a pontoon bridge to connect Europe and the Asian continent.


There are two types of pontoon structures: 1 The traditional form is to erect the beam on the ship or pontoon, and then resurface the bridge. 2 The form of the combination of the boat and the beam, or the ship is connected end to end, in a tandem type, or the boat body is closely arranged into a belt type. In order to keep the position of the pontoon axis from shifting, cable anchors are required on the upper and lower sides. In order to connect with the two sides, a transition beam or springboard is required on both sides. In order to adapt to the fluctuation of the water level, the two sides of the strait should also be equipped with lifting docks or lifting bridges.


The pontoon can be used for pedestrian, road and railway. The structure is not complicated, and the racking is convenient, but the maintenance cost is high. It can be used as an emergency rescue facility or as a temporary transportation facility. It can be used in wartime to ensure that the army can quickly pass through the military raft bridge. In order to increase its mobility, it is usually made of light metal.
