本文是某工程塌方处理的经验总结.它恰当地采用管棚法与注浆加固法相结合,安全、可靠、高效的处理了塌方段.这种方法,可以超前预先加固塌方虚碴,使管棚支撑与虚碴自稳相结合,充分发挥管棚法与注浆加固法的优点,避免了两者的局限性.文中详细地介绍了方案和施工方法,在虚碴中进行大导管的安置,遇到许多实际困难,这些问题的解决,丰富了处理塌方施工技术经验.施工过程中,采用了监控法,绘出收敛量测结果.
This paper summarizes the experience of landslide treatment of a project, and properly combines the roof shedding method with the grouting reinforcement method to handle the landslide section safely, reliably and efficiently.This method can pre-reinforce the landslide false ballast, The combination of support and false ballast self-stabilization, give full play to the advantages of pipe shedding method and grouting reinforcement method, and avoid the limitations of both.The scheme and construction method are introduced in detail in this paper, Encountered many practical difficulties, the solution of these problems has enriched the technical experience of dealing with landslide construction.In the process of construction, the monitoring method was used to draw the convergent measurement results.
