摘要
浅埋暗挖法是以注浆超前支护技术、格栅拱架制造技术、正台阶环形留核心土方法、监控量测技术等为基础发展起来的一种适用于浅埋隧道施工的技术。结合某浅埋的人行地道工程,采用劈裂注浆法对隧道土夹石地层进行水泥-水玻璃双液浆注浆提高松散土夹石的自稳能力,用全断面长短管注浆相互结合的方法对砂层进行水泥-水玻璃双浆液注浆,成功穿越不良地质段。
Mining method for ultra-shallow tunnel construction is a technology developed from grouting support technology, grid arch manufacturing technology, bench excavation ring cut method and monitoring measurement technology. A combination of the shallow People＇s Bank Road Project, grouting the tunnel soil-stone for- mation cement-sodium silicate double injected significantly improved lcnxse soil with stone from stable, and full- face with the length of pipe each other right combination of sand for cement-sodium silicate double injected, success through adverse geological sites .
