高海拔区深斜井衬砌施工技术研究

Study on Lining Construction Technology of Deep Inclined Shaft in High Altitude Area

布仑口—公格尔水电站地处高海拔区,其压力管道斜井段是目前国内已建和在建中倾角最大的深斜井之一,工程施工难度大、施工安全因素复杂。通过技术研究,斜井段衬砌施工在钢管安装和混凝土回填等方面做了一定的技术改进,保证了斜井段衬砌的施工安全和施工质量,并具有良好的经济性。

The Bulunkou-Konggur Hydropower Station locates in high altitude area. Its inclined section of penstock is one of the biggest deep inclined shaft among the shafts which have been built and being built in China at present. The construction of shaft is very difficult and has complex security factors. Through technology research, the lining construction of inclined shaft is improved from the aspects of steel pipe installation and concrete backfill. The technical improvements ensure the lining construction safety and construction quality, and also achieve a good economic benefit.
