超长底轴翻板闸门吊装关键技术

Key Hoisting Technology of Ultra-long Bottom Shaft Sluice Gate

杭州市富阳区北支江上游水闸与船闸均采用底轴驱动式翻板闸门,施工和质量控制难度均较大。依托该工程,详细介绍闸门吊装过程。通过对管节不同吊点进行受力分析,确定最佳吊点,再综合考虑管节运输过程中的道路状况和质量控制,优化吊装方案,解决了超长底轴翻板闸门吊装施工质量控制难题,保障了施工进度和安全。

The bottom shaft sluice gate is adopted for the sluice and ship lock in the upper reaches of the Beizhijiang River in Fuyang district, Hangzhou, which is difficult in construction and quality control. Based on the project, the sluice gate hoisting process is introduced in detail. Through the stress analysis of different hoisting points of the pipe joint, the best hoisting point is determined, and then the road conditions and quality control in the process of pipe joint transportation are comprehensively considered to optimize the lifting scheme, which solves the difficult problem of lifting construction quality control of the ultra-long bottom shaft sluice gate and ensures the construction progress and safety.
