Mechanical construction method for multi-stage vertical shaft structure of water diversion system of pumped storage power station
The invention provides a mechanical construction method of a multi-stage vertical shaft structure of a water diversion system of a pumped storage power station, which adopts a full-mechanical construction method of directional drilling, raise boring and a vertical shaft reaming heading machine, and is a feasible technical approach for solving the problems of many underground operating personnel, complex working procedures, difficult safety control, environmental pollution and the like in the existing vertical shaft blasting and building. Directional drilling can remarkably improve the perpendicularity of the deep shaft and further control the deflection rate of the shaft. The raise boring machine and the vertical shaft expanding excavation heading machine serve as representative technologies and equipment in the development direction of few people, mechanization, standardization and intellectualization and have outstanding advantages in the aspects of quality, construction period, safety, environmental protection and civilized construction, integrated construction operation of excavation, deslagging, supporting, guiding and the like is achieved, the construction speed of a heading machine method is 3-4 times that of a drilling and blasting method, and the construction efficiency is greatly improved. The excavation efficiency of the vertical shaft is remarkably improved, and the method is an effective way for achieving mechanical and intelligent construction of the vertical shaft of the pumped storage power station.
本发明提供一种抽水蓄能电站引水系统多级竖井结构的机械化施工方法，采用“定向钻+反井钻+竖井扩孔掘进机”的全机械化施工方法，是解决现有竖井爆破建井井下作业人员多、工序复杂、安全管控困难和环境污染等问题的可行技术途径；定向钻可显著提高深竖井的垂直度，进一步控制竖井的偏斜率；而反井钻机和竖井扩挖掘进机作为“少人化、机械化、标准化、智能化”发展方向的代表性技术与装备，在质量、工期、安全、环境保护与文明施工方面具有突出优势，实现了开挖、出渣、支护、导向等一体化施工作业，掘进机法施工速度是钻爆法的3～4倍，显著提高了竖井的开挖效率，是实现抽水蓄能电站竖井机械化、智能化建造的有效途径。
