三峡升船机平衡重系统安装技术

摘要

The installation technology of counterweight system of Three Gorges Project ship lift has been studied in this paper based on the construction requirements of counterweight system and construction environment. The overall installation procedure of counterweight system has been put forward which are suitable for Three Gorges Project. Then the construction processes and construction methods of balance chain guide installation, balancing pulley installation,main hoist rope installation and counterweight installation have been described in detail. At the same time,the installation technology system of counterweight system is set up. This construction technology effectively solves many problems faced in the installation process of counterweight system of Three Gorges Project ship lift,such as large scale project,large component size,high accuracy requirements,high installation elevation,difficult construction,construction with wide distribution,complex construction conditions, etc. Meanwhile,the technology provides a good reference for similar projects at home and abroad.%针对三峡升船机平衡重系统安装要求并结合现场综合环境，对三峡升船机平衡重系统安装技术进行研究。提出了适宜三峡升船机平衡重系统安装的总体程序，并分别对总体程序中的平衡链导向装置安装、平衡滑轮组安装、主提升钢丝绳安装和平衡重组安装等子工序提出了详细的施工流程以及施工方法，建立了一套完整的升船机平衡重系统安装技术体系。该项施工技术有效解决了三峡升船机平衡重系统安装过程中面临的工程规模大、构件尺寸质量大、技术精度要求高、安装高程高、施工难度大、施工点多面广和施工现场条件复杂等技术难点，为国内外类似工程实践提供了很好的参考。
