500 m级超深竖井开挖方案的比选与施工
|
摘要
在水电工程领域,500 m级超深竖井工程极为少见,而对于500 m级超深竖井的开挖施工,目前还没有一个完全成熟的施工技术和经验可供借鉴。通常竖井可选的开挖方案主要有反井法、正井法、正反井相结合开挖法等。因此,如何合理地选择竖井开挖方案是保证竖井施工安全、施工质量、施工进度的重要前提之一。以中东抽水蓄能电站500 m级竖井工程为例,介绍了超深竖井开挖方案的比选与施工,可为今后类似竖井工程施工提供参考。
In the field of hydropower engineering, 500 m ultra-deep shaft engineering is very rare. However, there is not a fully mature construction technology and experience for the excavation of 500 m ultra-deep shaft. Usually, the main alternative excavation schemes of the shaft are the reverse shaft method, the normal shaft method and the combination of the normal and reverse shaft methods. Therefore, how to reasonably select the excavation scheme of the shaft is one of the important preconditions to ensure the safety, quality and progress of the shaft construction. Taking the 500 m shaft project of Middle East Pumped Storage Power Station as an example, this paper introduces the selection and construction of excavation schemes for ultra-deep shaft, which can provide reference for similar shaft construction in the future.
