上跨高铁营运线的安全防护棚拆除技术研究

Study on Demolition Technology of Safety Protection Shed Overcrossing High-Speed Railway Operation Line

以杭州南站杭长场安全防护棚的拆除施工为例,针对因上跨高铁营运线导致实际施工场地空间不足而无法进行吊装的难题,详细介绍了利用自主设计的轨道工装胎架进行安全防护棚拆除的施工技术。经实践应用,该施工技术具有操作简便、安全可靠、满足既有线路的运营要求等特点,在类似工程的施工中具有广阔的应用前景。

Taking the Safety Protection Shed demolition construction of Hangzhou South Railway Station Hangchang site as an example,aiming at the problem that the space of the actual construction site is insufficient and the hoisting can not be performed due to overcrossing high-speed railway operation line,the safety shed demolition construction technology using the self-designed track assembly jig is introduced in detail.Through practical application,the construction technology is characterized by simple operation,safety and reliability,and can meet the operation requirements of existing lines,which has broad application prospects in the construction of similar projects.
