为解决隧道不良地质、土体松散,影响隧道施工安全的难题,本文通过理论联系实际的方法,以赣龙复线铁路GL-1标梓山隧道出口施工为例,重点阐述地表袖阀管注浆施工方法。本文通过对袖阀管注浆施工应用技术的探讨可知,采用袖阀管施工技术措施,工艺方法合理可行、效果显著,节约了大量的材料,同时减少了施工劳动强度,减少了成本支出,提高了效率。 In order to solve the problem of poor geology of the tunnel and loose soil and affecting the safety of the tunnel construction, this paper focuses on the grouting construction of the surface sleeve valve tube by taking the construction of the GL-1 standard Azusa tunnel exit of Ganlong Multi-line Railway as an example, method. In this paper, the application of sleeve valve grouting construction technology shows that the use of sleeve valve pipe construction technology measures, process method is reasonable and feasible, the effect is significant, saving a lot of material, while reducing the labor intensity of construction, reduce costs and increase Efficiency.
