At noon on January 24, in the 10,000-hectare blue waves of the East China Sea, a 70-meter box girder weighing more than 1,800 tons was slowly placed on the high quay on the north span of the Bridge’s main navigation hole. Zhoudai for a large floating crane Ningbo Zhoushan Port Main Canal Project realized the main line through.

From Zhejiang provincetrafficGroup leaderinvestmentThe Ningbo Zhoushan Port Main Canal Project under construction, with a total length of 36.78 kilometers,Total inversionApproximately 16.3 billion yuan, connecting the five islands of Fuchi Island, Zhoushan Island, Changbai Island, Daishan Island and Yushan Island, crossing 5 waterways, according to data from two four-lane roads.highwayThe standard design is scheduled to be completed and open to traffic by the end of 2021. Among them, the Yushan Bridge and the Fuchimen Bridge were completed and opened to traffic in 2018 and 2019 respectively. This year, Ningbo Zhoushan Port Main Crossing Project will connect to Yongzhou Expressway after the completion of the entire line, bringing the total construction mileage of the Zhoushan Island Interchange project to 83 kilometers, spanning 8 islands and having 10 bridges.This super traffic project after the Hong Kong-Zhuhai-Macao Bridge, which is well known in the industry, will connect with Shanghai to the north in the long term and become the longest island in the world .highwayAnd the biggest cross in the seabridgeGroup, for Shanghai, Ningbo, Zhoushan to form the shortest land transportation, which is important to improve the comprehensive regional transportation network and support the country.industrydesignplanning1. It is of great importance to promote the integrated development of the Yangtze River Delta.

“Zhoudai Bridge is an important part of the Shanghai-Zhou-Yong Sea Pass. After the main line of the bridge is completed, the project will gradually turn into the construction of the bridge platform, including pavement engineering, housing construction and traffic safety engineering To be completed by the end of this year Open to trafficobjectivesIt laid a solid foundation. “

Zhejiang Transport Group Main PassageBuildingSaid the relevant person in charge of the command. After the completion of the entire Zhoudai Bridge, the era of suspended islands in the sea in Daishan will end completely, bringing a “reinvented” revolution to the location of transportation, urban development and industrial modernization of Daishan.

　　China’s longest and heaviest sea crossing box girder

The Zhoudai Bridge has a total of 370 box girders, with a single piece measuring 70 meters in length and weighing 1,854 tons. It is the heaviest and longest concrete box of cross bridges under construction in China.China Railway Bridge Group Co., Ltd.the companyThe first pre-production of the film was completed on October 4, 2018, the first installation of the film was completed on April 18, 2019, and all pre-production tasks were completed on October 12, 2020.

To ensure that box girder production meets Zhoudai BridgeConstruction periodAs required, the project department installed two box girder production lines at the Jintang Precast Plant, which produced 6 sets of steel cage tying placeholders, 6 sets of steel box girder outer molds stainless steel and 6 sets of complete hydraulic internal molds. To allow these “monsters” to transfer freely from the beam making pedestal to the beam storage pedestal, they can also be seamlessly transferred from the beam storage pedestal toGo to seaDocktransportOn the ship, the project department specially designed two 1200-ton beam handling machines for these “bigs”. It is worth mentioning that the beam handling machine has also been certified as the “China’s largest rubber-tire crane” by Shanghai Great World Guinness Headquarters.
