摘要
通过对新金华山隧道洞身段大管棚导向跟管技术穿过软弱粘土层的应用,阐述了这种管棚技术运用的原理及施工过程,对今后隧道软弱地层使用管棚超前支护防止管棚偏向起到指导作用。
Through the application of large pipe shed orientation casing while drilling technology through the soft clay layer in new Jinhua mountain tunnel hole body section,this paper elaborated the application principle and construction process of this kind of pipe shed technique,had referenced effect to future tunnel soft ground using pipe shed advanced support to prevent the pipe shed orientation.
