The double-width conjoined steel beam of Wenzhou Oujiang Beikou Bridge adopts a walking intelligent lifting hydraulic system

This time, we came to the beautiful city of Yueqing and witnessed the successful completion of the synchronous lifting of the double-width conjoined steel beams of the Wenzhou Oujiang Beikou Bridge using the walking intelligent lifting hydraulic system. When the construction of the bridge is completed, the list of world-renowned bridges will be Lick another heavyweight member.

Oujiang Beikou Bridge is the world's first three-tower, four-span, double-layer steel truss girder suspension bridge, the first long-span high-speed, dual-purpose suspension bridge for national roads in China, and one of the most technically difficult and complex bridges in my country and even in the world, with a total length of about 7.9 Kilometers, using innovative technologies in many fields. It is the first time in China to apply BIM technology in the whole cycle in bridge construction projects.

Beijing Bridge Civil Construction 2nd bid line has a total length of 3.23 kilometers, mainly including the North Tower, North Anchorage and North Approach Bridge. The North Approach Bridge has a total of 510 sections of steel beams, with a total weight of about 19,000 tons, and the lifting construction is 1.01 kilometers long. The lifting beam section is designed in various styles such as vertical and horizontal slope, curved section, variable section section and variable longitudinal slope section, with a maximum lifting length of 560 meters, which is extremely rare in domestic steel beam lifting construction. The lifting is a major technological innovation to solve the problem of lifting of the double-layer section of the steel beam. The walking-type intelligent lifting hydraulic system adopted in the project is a key to the technological innovation. The system is mainly composed of hydraulic oil circuit, electrical It is composed of multiple parts such as control, mechanical steel structure support, friction reduction and slippage, etc., which effectively integrates machinery, electricity and hydraulics, so as to realize multi-point reciprocating lifting, lifting, deviation correction and other actions during the construction process. While simplifying the construction process, the construction period is greatly reduced.

Canete has resumed work and production in an orderly manner on the premise that prevention and control are not relaxed during the epidemic, and the existing production capacity has basically recovered. As a professional manufacturer of lifting and lifting intelligent control hydraulic systems, we provide high-quality synchronous lifting, lifting, and lifting hydraulic systems for major bridge construction and maintenance projects, as well as timely after-sales support in subsequent product use to ensure Major projects were implemented in a timely and smooth manner.
