地表定向钻超前灌浆技术在引江补汉工程中的应用
Application of surface directional drilling advance grouting technology in the Yangtze-to-Han River Water Diversion Project
摘要
Abstract
With the full implementation and in-depth advancement of the National Water Network Strategy,the construction of inter-basin water diversion projects in China is characterized by long-distance water conveyance,the deployment of deep-buried tunnels,and high geological risks.Water inrush and mud outburst disasters during the construction of long,deep-buried tunnels crossing unfavorable geological bodies have become the core bottlenecks restricting the safe and efficient construction of these projects.Featuring parallel operation,high safety and controllability,and favorable treatment effects,surface directional drilling advance grouting technology has gradually become a key technology for advance treatment of unfavorable geological sections in deep-buried tunnels.This paper systematically reviewed the current application status and development bottlenecks of surface directional drilling advance grouting technology in the water conservancy industry.Based on the first large-scale and systematic application of this technology in China,implemented in the Yangtze-to-Han River Water Diversion Project,this paper established a complete technical framework,covering selection principles for tunnel sections requiring treatment,design of grouting reinforcement rings,determination of key grouting parameters,phased grouting construction processes,and the dynamic management and control system of"pilot testing,parameter optimization,and full-scale construction".Combined with its ongoing application in the typical Huanghua fault in the Yangtze-to-Han River Water Diversion Project,this paper verified the engineering applicability and technical reliability of this technology in preventing and controlling water inrush and mud outburst disasters in complex unfavorable geological bodies.A complete technical system integrating design,construction,and inspection was established,filling the gap in the large-scale application of this technology in ultra-long deep-buried water conveyance tunnels in China.Finally,this paper pointed out key technical research directions,including deep borehole stability,precise control of slurry diffusion,and quantitative evaluation of grouting effects.Relevant suggestions for accelerating the development of industry standard systems were also proposed to provide technical reference for water inrush and mud outburst disaster control in similar projects under the National Water Network.关键词
