700m级大断面超深竖井正井法施工凿井设备选型及应用

Selection and Application of Drilling Equipment for the Construction of 700 m Level Large Cross-section Ultra Deep Vertical Shaft UsingNormal Shaft Method

北疆供水二期工程总长540 km,隧洞占总长度的95.6%,均为深埋超特长隧洞,对该输水隧洞工程中大断面超深竖井正井法施工凿井设备选型及应用技术进行总结,通过对竖井提升系统相关设备选型对比分析研究,形成一套水利行业超深竖井施工设备选型的技术理论知识。

The total length of North Xinjiang Water Supply Phase II Project is 540 km,with tunnels accounting for 95.6%of the total length,all of which are deeply buried and ultra long tunnels.This paper summarizes the selection and application technology of drilling equipment for the construction of large cross-section and ultra deep vertical shafts using the vertical well method in the water conveyance tunnel project.Through comparative analysis and research on the selection of equipment related to the vertical shaft lifting system,a set of technical and theoretical knowledge for the selection of ultra deep vertical shaft construction equipment in the water conservancy industry has been formed.
