• [The reconstruction project of Tangguantun overpass on Jincang Expressway has started]
• Recently, the renovation and expansion project of Tangguantun overpass on Jincang Expressway, undertaken by Tianjin Company of China Railway Sixth Bureau, officially started, marking the comprehensive start of the overall lifting and dismantling construction of the heaviest railway continuous beam in North China. As a key node in the full line connection of the Jincang Expressway renovation and expansion project, this project is of great significance for improving the regional transportation network and strengthening the transportation support for the coordinated development of Beijing Tianjin Hebei. The project is located in Jinghai District, Tianjin City, and will be upgraded and renovated using the "demolition of old and construction of new" model. The main content includes the demolition of existing bridges, the construction of new rotating bridges in situ, and the construction of road surface ancillary facilities. The existing Tangguantun Overpass has a total length of 474.4 meters and 21 spans. The difficulty of dismantling the continuous beam of the 10th span of the Beijing Shanghai Railway is outstanding - with a dismantling length of 43.5 meters and a beam weight of 1200 tons, it sets a record for the largest scale of cross railway beam dismantling operations in North China. At the same time, the new rotating beam is an asymmetric balanced rotating structure, and coupled with the need to ensure the safe operation of the Beijing Shanghai Railway, one of the busiest trunk lines in the country, the project faces dual technical and safety challenges.Editor/Bian Wenjun

The project starts from Zixiao Avenue and ends at Renwei Road, with a total length of about 1.01 kilometers. It is constructed according to the standards of urban secondary roads, with a designed speed of 40 km/h and four lanes in both directions. The total investment is about 150 million yuan. The core of the project is the construction of two cross road bridges: the bridge spanning Zixiao Avenue has a total length of 350 meters and is designed with four lanes in both directions; The bridge spanning Fuzhou Road has a total length of 114 meters, a red line width of 33 meters, and a dual six lane configuration. The project includes a total of 42 pile foundations, with the deepest pile foundation reaching 61 meters. Currently, the excavation, pouring, and backfilling work of 7 foundation pits west of Zixiao Avenue has been completed. It is planned to complete all pile foundation construction before the end of the year, and key processes such as steel box girder hoisting and closure will be promoted in the future. At the same time, some road surface cleaning and leveling operations are carried out simultaneously.Editor/Bian wenjun
