冲沟浅埋段地表袖阀管注浆加固技术的应用

Application of Grouting Reinforcement Technology for Valve Tube in Shallow Burial Section of Gully

伴随着西部地区经济的飞速发展,越来越多的铁路、公路穿越西部黄土地区,黄土隧道不良地质段施工也随之增多.袖阀管注浆技术对郭旗隧道冲沟浅埋段土体的加固效果非常好,且省去了复杂的超前支护措施及开挖工法,明显提高了施工效率,大大加快了施工进度,同时也有了施工安全保障,为今后类似的黄土隧道穿越浅埋段施工提供借鉴和参考.

With the rapid development of the western economy, more and more railways and highways pass through the western loess area, and the construction of the bad geological section of the loess tunnel is also increasing. The reinforcement effect of Guo Qi tunnel grouting technology in shallow buried section soil sleeve valve tube is very good, the complicated advance support measures and excavation methods are omitted, the construction efficiency is obviously improved, the construction progress is greatly accelerated, and the construction safety guarantee is also provided, which provides reference for the similar construction of the shallow loess tunnel in the future.
