复杂板梁结构条件下盘扣式钢管支架的设计与应用

Design and Application of Ring Lock Steel Scaffold under the Condition of Complex Plate Girder Structure

盘扣式钢管支架作为一种新型脚手架技术被引入白鹤滩水电站左岸地下厂房中使用。阐述了白鹤滩水电站用于左岸主变洞混凝土浇筑施工的盘扣式钢管支架的设计与应用情况,分析了复杂板梁结构下盘扣式钢管支架支撑中的若干问题,总结了盘扣式钢管支架支撑复杂板梁结构的注意事项。

As a new type of scaffold technology,the ring lock steel scaffold is used in the left bank underground powerhouse of Baihetan Hydropower Station.This paper describes the design and application of the ring lock steel scaffold for the concrete casting construction of the main transformer tunnel on the left bank of Baihetan Hydropower Station,analyzes some problems in the support process of the ring lock steel scaffold under the complex plate girder structure,and summarizes the matters need to be noticed as the ring lock steel scaffold supporting the complex plate girder structure.
