抽水蓄能电站地下洞室集群修建TBM关键技术研究与应用

To address the various problems in excavation of the underground tunnels of pumped storage power sta⁃ tions, such as long construction period, large construction difficulties, and high safety risk, this paper takes into ac⁃ count the types and characteristics of underground tunnels and puts forward three key technologies: large-diameter small-turning radius TBM, Elf TBM, and large-inclined shaft TBM. The study also develops three improved TBM equipment, which are applicable to the construction of traffic tunnels, drainage galleries, and water diversion inclined shafts respectively. In view of the short construction length of single power station and the large development scale of power station groups, this paper carries out a study on the key technologies of intelligent TBM tunnelling. Based on a cloud computing platform and big data collection and analysis, this paper plans a construction platform system for the intelligent excavation of pumped storage power stations. The study applies large-diameter small-turning radius TBM equipped with vibration monitoring and TBM-SMART intelligent tunnelling system in the traffic tunnels of Funing Pumped Storage Power Station and realizes the analysis and sharing of the tunnelling data. It also applies the Elf TBM, which is equipped with ground remote control and the TBM-SMART intelligent tunnelling system and vibration monitoring technology, in the drainage galleries of several pumped storage power stations to realize the continuous con⁃ struction of the power station groups. © 2023 Editorial By Modern Tunnelling Technology.
