摘要
随着我国高速路网的不断完善,城市快速路大量修建,互通小半径曲线钢箱梁吊装施工技术也得到了迅速的推广和应用。互通小半径曲线钢箱梁吊装施工技术要求快速、安全、优质,因此对于工程项目施工组织、技术要求颇高。文章以苏州G312-G524节点工程为依托,对城市快速路节点互通小半径曲线钢箱梁吊装施工技术进行研究。针对其环境复杂、施工场地限制且安全控制要求高等难题,在钢箱梁吊装施工中采取分块分节制作、BIM施工模拟等技术措施,解决了复杂环境下城市互通立交临近220 kV高压线的小半径曲线钢箱梁吊装的难题,为今后类似环境钢箱梁吊装施工提供借鉴。
With the continuous improvement of China’s highway network,a large number of urban expressways have been built,and the construction technology of steel box girder hoisting with small radius curve has been rapidly promoted and applied.The construction technology of steel box girder hoisting with interworking small radius curve requires fast,safe and high quality,so the construction organization and technology requirements of engineering projects are quite high.Based on Suzhou G312-G524 node project,this paper studies the construction technology of steel box girder hoisting with small radius curve of urban expressway node communication.In view of its complex environment,construction site restriction and high safety control requirements,technical measures such as block and section production and BIM construction simulation are adopted in the construction of steel box girder hoisting,and the problem of hoisting steel box girder with small radius curve near 220 kV high voltage line of urban interchange in complex environment is solved,which provides reference for hoisting construction of steel box girder in similar environment in the future.
