大直径立井井筒平面布置快速施工技术

The Rapid Construction Technology of Layout of Large-diameter Vertical Shaft Wellbore

较大直径的井筒,在施工设备选型及布置是比较容易;但在快速施工中井筒平面布置的优化尤为重要,例如大提升机、大吊桶,大整体液压模板等立井施工机械化作业线。大海则项目部月平均成井110m,最高月成井120m.工程质量优良。井筒平面布置的优化,为安全快速施工创造了良好的条件。

The equipment selection and layout of large-diameter borehole is relatively easy in the construction; but it is particularly important to optimizing wellbore layout in the rapid construction, such as, large hoist, big bucket, large overall hydraulic templates and other vertical shaft construction mechanized lines. The monthly average well of Dahaize project department is ll0m, the highest monthly average is 120m, and the project quality is excellent. The optimization of the layout of wellbore creates favorable conditions for safe and rapid construction.
