【摘要】：巴基斯坦N-J水电工程调压竖井井壁衬砌采用滑模施工。为进一步提高滑模施工的安全性、可靠性及混凝土衬砌质量,降低劳动强度,对滑模的下料系统、模板系统进行了优化改造,并从多角度比较分析了不同施工方案的优劣。滑模生产实际及受力有限元分析结果表明,其结构强度满足施工要求。此外,通过方案对比分析,介绍了该工程采用的竖井底部安装技术,可为相关工程提供参考。
[Abstract]:In order to further improve the safety, reliability and quality of concrete lining and reduce the labor intensity, the sliding form is used in the lining of the pressure regulating shaft shaft of N-J hydropower project in Pakistan, so as to further improve the safety, reliability and quality of concrete lining in the construction of sliding formwork. The formwork system is optimized, and the advantages and disadvantages of different construction schemes are compared and analyzed from many angles. The results of sliding formwork production and finite element analysis show that the structural strength meets the construction requirements. The installation technology of shaft bottom used in this project is introduced, which can provide reference for related projects.
