摘要
通过水平旋喷在沙哈拉峁隧道中的首次应用实例,详细阐述了水平旋喷预支护技术的工艺参数、施工过程及加固效果,并对旋喷所用工时及材料消耗作出统计,结果表明该技术在软弱砂层隧道预支护应用中的良好效果。
Based on the application of horizontal jet grouting reinforcement technique in Shahalamao railway tunnel,the technologic parameter,construction process and improvement effect of this technique are mainly introduced. The work efficiency and material consume are analyzed also. It is shown that the horizontal jet grouting reinforcement technique can be used to construct the tunnel in soft sandy soil.
