摘要
为更好的推进TBM(隧道掘进机)在国内抽水蓄能电站引水斜井中的试点应用,对斜井TBM施工中的关键技术问题进行了深入研究。对TBM开挖料可利用性进行的试验研究,提出了TBM开挖料的利用方向;对TBM开挖出渣方式、溜渣角度的研究,推荐保留斜井中部施工支洞,并为斜井倾角设计提供了依据;研究成果为国内首次针对抽水蓄能TBM施工关键技术提出了应用方案。
To promote the application of the TBM construction technology in inclined diversion shaft in pumped storage power stations,the key technical issues in the TBM construction of inclined shaft are analyzed in detail.Based on the experimental study of the utilizability of TBM excavated materials,possible utilization directions are discussed.For the discharge scheme and slipping angle of the excavated residue,it is recommended to keep the construction adit in the middle of the inclined shaft and suggestions are made for the angle of the shaft.The application scheme proposed in this study is the first one on the key technologies for TBM construction in pumped storage power stations.
