Abstract
During the construction of pumped storage power stations,scaffolding is used as the form work sup-porting structure system in many parts of the structural concrete construction.Especially for the concrete and concrete lining construction of underground powerhouse rock wall crane beams,tailgate tunnel rock abutment beams,upper and lower reservoir inlet and outlet,and hoist room structures,due to the total construction load and concentrated total load exceed certain limit,frame height and span being excessive,the formwork bearing structure system has become a more dangerous sub-project exceeding a certain scale.How to select a form-work system with safe and reliable structure,convenient for on-site construction and reasonable cost in the con-crete construction of pumped storage power stations with complex structure and overload is very important.The formwork system must adhere to the principle of safety first from structural design,expert evaluation to on-site implementation.Taking Zhejiang Ninghai Pumped Storage Power Station as a successful case of com-prehensively applying high-strength bowl-buckle scaffolding as the concrete formwork support system for an ultra-hazardous large-scale project,this paper expounds the characteristics and advantages of high-strength bowl-buckle scaffolding,and provides reference for the construction of pumped storage power stations.关键词
