TBM-based water diversion inclined shaft arrangement structure of pumped storage power station and construction method
The invention discloses a pumped storage power station diversion inclined shaft arrangement structure based on a TBM and a construction method, and belongs to the technical field of water conservancy and hydropower engineering. One end of the upper adit section is communicated with the top end of the first-stage long inclined shaft; one end of the lower adit section is communicated with the bottom end of the first-stage long inclined shaft through a machine disassembling hole; one end of the second construction adit is communicated with the middle lower part of the first-stage long inclined shaft; the ground assembly foundation pit is arranged above the upper adit section, the ground assembly foundation pit is communicated with the first-stage long inclined shaft through the inclined shaft extension hole, and the inclined shaft extension hole is coaxial with the first-stage long inclined shaft. According to the water diversion inclined shaft arrangement structure, the number of vertical face corners can be reduced, the length of a water diversion system is shortened, head losses are reduced, the benefits of a pumped storage power station are increased, investment and the construction period can be saved, construction convenience is better, and safety is higher.
本发明公开了水利水电工程技术领域的一种基于TBM的抽水蓄能电站引水斜井布置结构及施工方法，包括一级长斜井；上平洞段，上平洞段的一端与一级长斜井的顶端连通；下平洞段，下平洞段的一端通过拆机洞与一级长斜井的底端连通；第二施工支洞，第二施工支洞的一端与一级长斜井的中下部连通；地面组装基坑，地面组装基坑设置在上平洞段的上方，且地面组装基坑通过斜井延伸洞与一级长斜井连通，斜井延伸洞与一级长斜井同轴。本发明的引水斜井布置结构不仅可以减少立面拐弯数量，缩短引水系统长度，降低了水头损失，增加了抽水蓄能电站效益，还可以节省投资和工期，且施工便利性更好，安全性更高。
