摘要
本文以古交兴能电厂至太原供热主管线及中继能源站工程隧道工程第三合同段2#通风斜井(坡度-46.6%)中仰拱施工为实例,详细介绍了大坡度斜井仰拱混凝土浇筑的方法选择、工艺流程、关键技术控制点等,形成成熟的大坡度仰拱混凝土浇筑施工工艺。
This paper takes the inverted arch construction in 2# ventilation shaft of the third contract segment in Zhingji Energy Station tunnel construction of the heating line from Gujiao Xingneng Power Plant to Taiyuan as the example to describe the methods selection,process flow, key control points of the concrete pouring of large slope inclined arch to form the mature large slope arch concrete pouring construction technology.
