摘要

为解决全断面硬岩掘进机（TBM）在抽水蓄能电站应用受限的难题，研究设计一种可实现超小转弯半径的紧凑型TBM。首先，结合抽水蓄能电站排水廊道隧洞工程的地质条件和特点，对紧凑型TBM设计特点进行分析，提出紧凑型TBM应用于抽水蓄能电站排水廊道隧洞工程时需要考虑和解决的关键问题，例如刀盘破岩能力、小半径曲线掘进及过站施工工艺等，以提高紧凑型TBM的适应性及成洞效率；然后，对紧凑型TBM小半径转弯掘进、快速过站和高效破岩等针对性设计和优化改进措施进行研究，包括新型推进系统设计、超小转弯半径自动导向系统设计、一体化皮带机设计、一字布置单片式TBM中心刀、偏刃滚刀结构设计等；最后，通过自主研制的紧凑型TBM在文登抽水蓄能电站排水廊道隧洞工程的实际应用证明，紧凑型TBM具有良好的地质适应性和高效的机械化施工优势。

Abstract

To promote the application of a fullface hard rock machine (TBM) in pumped storage power stations, a compact TBM with an ultrasmall turning radius is designed. First, based on the geological conditions and characteristics of the drainage gallery tunnel project of the pumped storage power station, the design characteristics of the compact TBM are analyzed. The major problems that must be addressed when a compact TBM is applied to the drainage gallery tunnel project of the pumped storage power station, such as cutterhead rock breaking capacity, smallradius curved tunneling, and station crossing construction technology, are proposed to improve the adaptability and tunneling efficiency of the compact TBM. Second, the targeted design and optimization improvement measures for the smallradius curved turning tunneling, rapid station crossing, and efficient rock breaking of the compact TBM are investigated, including a new thrust system, an automatic guidance system for an ultrasmall turning radius, integrated belt conveyor, and central and disc cutter structures. Finally, a selfdeveloped compact TBM with independent intellectual property rights is applied to the drainage gallery tunnel project of the Wendeng pumped storage power station. Results show good geological adaptability and positive mechanized construction advantages of the compact TBM.
