The Pingtan Strait dual-use bridge is a controlled project of the Fuzhou Pingtan railway, an extension of the Hefei Fuzhou railway and an important component of the Beijing Fuzhou corridor. It is of great significance for promoting the construction of the economic zone on the west coast of the strait and is a national key project.
The Pingtan Strait dual-use bridge is currently the most difficult bridge to construct in China and also the most difficult strait bridge under construction in the world. The project started construction at the end of 2013, and the Pingtan Strait where the bridge is located is one of the three major wind prone sea areas in the world, characterized by strong winds, high waves, deep water, and fast currents. According to statistics, there are over 310 days of strong winds above level 6 each year, and about 238 days of strong winds above level 7. The highest wave height is about 9.69 meters, and the maximum wind speed is about 45.8 meters per second, reaching a strong typhoon of level 14 or above. It was once known as the 'forbidden zone for bridge construction'. Its construction conditions are far worse than the already built Donghai Bridge, Hangzhou Bay Cross Sea Bridge, and Hong Kong Zhuhai Macao Bridge, especially the impact of wave and current forces, which is more than 10 times that of conventional inland river bridges such as the Yangtze River. The construction difficulty and risk are greater.
Four sets of HZS180D ocean engineering mixing plants of Fangyuan Group adopt a 3-cube box type bucket lifting mixing plant structure, a large angle and large capacity tipping bucket lifting system, the application of proprietary frequency conversion lifting technology, a fully welded metal steel plate reinforced packaging structure, creative design and use of a steel drum feeding belt conveyor system and a 3000 cubic meter ultra large storage batching machine, realizing a fully automatic transportation, conveying and storage solution for the continuous production of aggregates required for ultra large volume concrete on offshore steel structure platforms; The steel structure adopts anodizing measures to slow down and avoid the corrosion process of the equipment body, and special measures such as ship anti-corrosion coatings and spraying processes are adopted to solve the equipment damage caused by seawater wind corrosion and super strong wind pressure in the sea environment. It meets the usage conditions of 14 level strong typhoons and marine corrosive environments, and is currently the highest typhoon resistant marine engineering mixing plant in China!
Up to now, Fangyuan Group has participated in 9 sets of offshore platform projects.
The product was awarded the TOP50 of China's Construction Machinery Annual Products (2016)!
