大型抽水蓄能电站地下厂房桥式起重机安装空间狭小,而配置的桥式起重机大梁为超大超重构件,在施工中吊装难度较大。以辽宁蒲石河抽水蓄能电站地下厂房桥式起重机施工为例,介绍地下厂房桥式起重机安装施工技术,在厂房顶拱埋设天锚作为吊装受力点,主要利用天锚、滑轮组及卷扬机联合作用进行吊装施工。在安装过程中制定出严格的工艺措施,保证桥式起重机安装施工的质量和安全。
Large pumped storage station underground plant overhead crane installation space is small, and the configuration of the overhead crane girder is oversized components, hoisting more difficult in the construction. Taking the construction of bridge crane at the underground powerhouse of Pushihe Pumped Storage Power Station in Liaoning Province as an example, the construction technology of the bridge crane in underground powerhouse is introduced. The anchor is embedded in the roof arch of the plant as the lifting force point. Lifting construction. In the installation process to develop a rigorous process measures to ensure the quality and safety of the construction of the bridge crane installation.
