摘要
本文以西安地铁临潼线大学城站87m长大管棚施工为例,通过分析黄土地区地质条件下,采用“导向钻进法”施工大管棚的超前支护方式,详细论述了该施工技术的具体工艺流程,并对施工中的导向纠偏技术进行了探讨,以期为今后相似工程的隧道暗挖提供安全保障。
This paper takes the construction of 87m long and large pipe roof at the college town station in Lintong Line of Xi’an Metro, analyzes the geological conditions of the loess area, makes use of“ guide drilling method” to construct the long and large pipe roof forepoling, elaborates the specific process of this construction method and then discusses the orientation correction technology of the construction in order to provide security for similar engineering of underground tunnel in the future.
