摘要

为解决抽水蓄能电站平洞建设中机械化程度低、作业环境差、安全风险大、施工效率低的问题，研究一种能适应超小转弯半径施工的紧凑型TBM。该类型TBM在双护盾TBM基础上，取消尾盾、辅推油缸、管片拼装机，同时结合敞开式TBM的锚网喷支护系统进行TBM整机集成设计，包括“V”形推进系统设计、刀盘锻造厚板技术、刀具小刀间距设计、组合式耐磨保护设计、紧凑型整机设计、皮带机超小转弯适应性设计、一体式皮带机设计、远程操作系统设计。研究成果在文登抽水蓄能电站排水廊道建设工程中取得了成功应用。

Abstract

Tunnel construction in a pumpedstorage power station is characterized by low mechanization, poor operating environment, high safety risk, low construction efficiency, and other factors. Hence, a compact tunnel boring machine (TBM) for the construction of tunnel with an ultrasmall turning radius is developed. The need for a tail shield, an auxiliary thrust cylinder, and a segment erector is eliminated by the usage of a doubleshield TBM, and an integrated TBM is designed in combination with the open TBM anchor net spraying support system. Furthermore, the Vshaped propulsion system design, cutterhead thickplate forging technology, small cutterspacing design, combined wearresistant protection design, compact machine design, beltconveyor adaptability design for an ultrasmall turning radius, integrated belt conveyor design, remote operating system design, etc., are incorporated. The obtained research results have been successfully applied to the construction of the drainage corridor of the Wendeng pumpedstorage power station. 

Key words： pumpedstorage power station; compact TBM; ultrasmall turning radius; propulsion system; remote operation
