As the last party builds concrete
Built by yuan express railways ltd
It's built in the 11th of china
It's all right
This represents significant progress in project construction
A solid foundation has been laid for subsequent construction
This time, the cylon's high-speed cross-swidth beam, which is approximately 269 metres long, uses a continuous beam with a main cross of 136 metres, crosses the express highway with an average traffic of more than 30,000 days, is only 8. 78 metres above the surface of the high-speed highway, is a continuous beam with a maximum range from the high-swidth to the sun, and is constructed in 69 sections, requiring a total of 7355. 6 cubic metres of concrete。
In the face of multiple challenges such as high risk of trans-river construction, high traffic and limited operating space, the central steel 11 project team has established a safety netization management system, using the “symmetric + dynamic weighting” process and the “symmetrication + dynamic weighting” technique to safeguard the structural stability of the beams。
“in order to achieve the alignment of the millimetre-level deviations of the condensed segment, five monitoring points were placed on each side of the condensed segment, while a dedicated 24-hour real-time monitoring and dynamic adjustment of the high-range and axis lines on both sides of the condensed segment ensured an accurate structural posture. At the same time, in terms of matching design, by opting for a reasonable timing of construction by optimizing matching design, the effect of concrete contraction on bridges is effectively controlled, the alignment of the millimetre-level deviations of the condensation segment is achieved, and the goal of a high degree of coherence across the bridge is achieved.” the chief engineer of the four-point project at cebu high station, central iron eleven group ltd., stated that。
Cedars are the backbone of an easy-to-reach road between the guangdong peninsula and the long triangle, and a network of urban inter-city railways in the shandong peninsula. Once completed, the project will further refine the regional road network layout in shandong and northern jiangsu, greatly facilitating the movement of people from the old regions of the pumong mountains and the subei revolution, and will be of great importance in contributing to the economic and social development of the region, the ecological protection and quality development of the yellow river basin。
