Hangzhou Bay Sea-crossing Bridge Pile Construction â…£ Contract Technical Research

Hangzhou bay sea-crossing bridge project is the main highway line across ShenHai-Hangzhou national highway, is G92 (Hangzhou) ring road of component. Jiaxing ZhengGuDai Haiyan since north bridge across the sea, Hangzhou bay in broad waterways.36km length. Rugged construction environment, especially the wind speed is larger, and the wind extremely unstable, Engineering sweeping, but time is limited, the normal construction and construction process to ensure safety without effective, climate and delay period. Especially in this project, all for the steel tubular pile foundations in weather sloping piles, the sea using steel box pile construction, this was the first time in China.The thesis combines of Hangzhou bay sea-crossing engineering construction contract DuanCheng stage IV, the gulf bridge bearing steel box construction process were studied. In the analysis of hangzhou bay sea-crossing geographical location and topography and landforms, hydrological conditions and climate conditions of engineering, on the basis of bridge across the gulf pile construction, a detailed study of the characteristics of the construction process and technical solutions and construction scheme, measuring quality assurance measures, and analyzes and summarizes the construction experience of the deficiencies and success.Based on the engineering practice, just across the bay bridge pile construction technical problems during the process of research, the solution, summarizes the experiences for similar Bridges, providing reference and construction.
