长管棚施工技术在公路隧道软弱围岩中的应用

Application of Long Pipe Shed Construction Technology in Soft Surrounding Rock of Highway Tunnel

公路隧道是一种系统的、复杂的工程,若是遭遇软弱围岩极易存在较大的安全隐患,做好超前支护工作十分关键。本文首先针对公路隧道软弱围岩问题展开分析,其后从管棚支护技术的应用出发展开论述,详细分析了管棚技术原理与应用要点,并就某公路隧道工程探讨了长管棚施工技术的应用情况,以期可供参考。

Highway tunnel is a kind of systematic and complex engineering.If encountering weak surrounding rock,it is easy to have large security risks,and it is very important to do a good job of advanced support.This paper first analyzes the problem of weak surrounding rock in highway tunnel,and then discusses the application of pipe shed support technology,analyzes the principle and application points of pipe shed technology in detail,and discusses the application of long pipe shed construction technology in a highway tunnel project,in order to provide reference.
