草街水电站水轮机座环吊装方案及实施
|
摘要
草街水电站座环是水轮发电机组埋件施工中单件重量最大的部件,也是尺寸最大、体型不规则的部件。在主厂房安装间尚未形成、厂房桥式起重机尚未安装以及现场布置的起吊设备无法满足吊装要求的情况下,对草街水电站座环安装时现场的施工环境进行研究,分析了现场吊装的各种制约因素,合理优化空间,选用履带吊并采用双机抬吊法实施吊装。方案简单、经济,也为后续工作提供了有利平台。
The seat ring of Caojie Hydropower Station is the largest single embedded component in the construction of the hydroelectric generating unit,and it is also the largest irregular component. Under the condition that the erection bay in the powerhouse is not available,the powerhouse bridge crane has not been installed,and the lifting equipment on site is unable to meet the lifting requirements,the site construction environment for installation of the seat ring of Caojie Hydropower Station is studied,and all restrictive factors of on-site lifting are analyzed. Through reasonable optimization of space,deployment of crawler cranes and the use of double crane lifting,the simple and economical lifting scheme is proposed and implemented,which also provides a favorable platform for follow-up work.
