响洪甸抽水蓄能电站工程集碴坑预应力锚索施工

Construction of Prestressed Rock Anchor in Catch Pit of Xianghongdian Pumped Storage Power Station

响洪甸抽水蓄能电站发电隧洞集碴坑施工中 ,根据工程特性 ,采用了预应力锚索技术处理 ,并根据其具体情况 ,制定了相应的施工方案和施工技术措施 .开挖施工和岩塞爆破检验表明 ,预应力锚索施工获得成功 ,对集碴坑边墙和顶拱的整体性起到了很好的加固作用 。

According to the project's character the Prestressed Cable Technology was used.Based on the hallow's special situation,we drew up precedure.It indicate that the construction prestressed cable have succeed through the construction excaration and rock plug blasting.It not only has a function of consolidation for the unity of the hallow's abutment wall and crestarch,but also provides the experiences for the similar construction which use the Prestressed Cable Trchnology.
