en.Wedoany.com Reported - Recently, the steel box girder of the E-ramp crossing the Beijing-Shanghai Expressway, part of the HWK-JY3 bid section of the Shanghai-Wuhan Expressway expansion project undertaken by the Fifth Company of China Railway No. 10 Engineering Group Co., Ltd., was successfully erected. Located in Jiangyin City, Jiangsu Province, China, this bid section spans a total length of 5.5 kilometers and encompasses works including mainline bridges, interchanges, passage culverts, and other structures.
The steel box girder erected this time has a total length of 70 meters, with the section crossing the Beijing-Shanghai Expressway measuring 59 meters long and 10.5 meters wide, and a maximum single lift weight of 187 tons. The construction had to be carried out above the Beijing-Shanghai Expressway, which has an average daily traffic volume of 120,000 vehicles, leaving an extremely limited window period. The Fifth Company of China Railway No. 10 Engineering Group established an expert panel, joining forces with the Shanghai-Wuhan Expansion Project Headquarters, traffic police departments, traffic law enforcement agencies, and the Beijing-Shanghai Expressway Company to hold over ten scheme discussion meetings and four desktop simulation exercises, repeatedly verifying the hoisting plan.
Before construction commenced, a joint acceptance team was formed by multiple parties to conduct safety condition acceptance checks and special reviews on key aspects such as temporary assembly supports, linear monitoring point layout, and the hoisting environment. During the hoisting process, the construction team deployed one 500-ton crawler crane on each side of the Beijing-Shanghai Expressway to operate alternately, adjusting the segment elevation, pre-camber, and cross slope. Both sets of bidirectional hoisting operations crossing the Beijing-Shanghai Expressway were completed within 50 minutes, after which the expressway was promptly restored to smooth traffic flow.
Upon completion of the HWK-JY3 bid section of the Shanghai-Wuhan Expressway expansion project, the corresponding road segment will be widened to eight to ten lanes in both directions. Once the entire Shanghai-Wuhan-Wuxi-Yixing Expressway expansion project is finished, it will densify the transportation network of the Suzhou-Wuxi-Changzhou metropolitan area and enhance the level of interconnectivity in the Taihu Lake rim region.
