摘要
巷道在过破碎带、断层、软弱岩层等不良地层时,为了确保施工安全,常需进行超前支护,管棚法是超前支护的一种。本文介绍了超前支护的原理及一些常用的超前支护形式,重点对管棚式超前支护的机理进行了初步探讨,提供了其设计方法,为管棚式超前支护的设计提供了参考。
When the roadway has crossed the fractured zone, fauh, incompetent bed and other undesirable rock, it often requires advance timbering for safety. The pipe-shed support is a kind of advance timbering. This paper introduced the principles of the advance timbering and some common advance supports, and focused on the mechanism of the pipe-roof protection, which provided a design method and a reference for pipe-shed advance timbering.
