针对布仑口—公格尔水电站深斜竖井的导洞开挖过程中难以实现仪器全程控制其轴线的情况,预先在已开挖导洞顶部轴线的投影位置上确定三个悬垂线点位,通过悬垂线标定中轴线,使用激光束指导开挖方向,控制导洞的施工,完成了导洞的贯通。实践证明该方法在深斜竖井的施工中具有一定的实用价值。
針對佈崙口—公格爾水電站深斜豎井的導洞開挖過程中難以實現儀器全程控製其軸線的情況,預先在已開挖導洞頂部軸線的投影位置上確定三箇懸垂線點位,通過懸垂線標定中軸線,使用激光束指導開挖方嚮,控製導洞的施工,完成瞭導洞的貫通。實踐證明該方法在深斜豎井的施工中具有一定的實用價值。

In allusion to the situation difficult to control the axis with instrument during the excavation for the pilot well of the deep inclined shaft in Bulunkou-Kongur Hydropower Station,it is suggested here that through laying out three hanging wire points in advance to determine the axis of the pilot well,and using laser beam to guide the excavation direction and control the construction of the pilot well,the breakthrough of the pilot well could be completed.It is proved by practices that this method has a certain practical value in the construction of deep inclined shaft.
