引红济石输水隧洞工程TBM施工适应性初探

Preliminary Study on TBM in the Tunnel Project of the Water Diversion Project from Hongyan to Stone River

引红济石调水工程属省内的跨流域调水工程,输水隧洞长近20 km,工程采用钻爆法与TBM联合施工方案,工程区地质条件极为复杂,突发性涌水、地质断裂带、长距离隧洞排水、通风、出渣等问题对采用TBM施工提出了特殊要求。应尽早对引红济石工程施工要求的TBM设备进行研究,为设备采购、制造作好前期技术支持。

The water diversion project from Hongyan to Stone river project in Shaanxi Province is the inter-basin water transfer project, water conveyance tunnel length of about 20 km, the use of drilling and blasting method works ＋ TBM joint implementation plan. The project area has extremely complicated geological conditions, sudden gushing water, geological fault crack band, long-distance tunnel drainage, ventilation, transportation and other issues raised on the use of TBM construction of a special request. The research of TBM equipment should be started as soon as possible, in order to offer technical support for equipment procurement, manufacturing.
