呼和浩特抽水蓄能电站引水系统开挖研究

Study on excavation of water diversion system of Hohhot Pumped Storage Power Station

结合实际工程,介绍了呼和浩特抽水蓄能电站引水系统开挖采用的ALIMAK爬罐结合反井钻斜井导洞开挖的施工方案。其中,不但归纳了其施工方法的优点并简单地介绍了其施工的过程,而且介绍了其现场施工精度的控制措施,最后列出了现场斜井贯通的测量成果。本研究对类似工程斜井开挖有一定的参考价值。

Based on the actual project, the construction technology of excavating the pilot heading for the inclined shaft by rai- sing-boring machine combined with ALIMAK climber during the excavation of the water diversion system of Hohhot Pumped Stor- age Power Station is introduced herein; in which, not only the merits of the construction method are summarized along with the description on its construction process, but the measures for the control of the in situ construction precision are also presented, furthermore, the measurement result of the breakthrough of the inclined shaft is finally listed as well. This study has a certain ref- erence value for the excavation of inclined shaft of the similar project.
