摘要
锚杆支护是一种广泛运用的岩土锚固技术,而随着工程经济的发展,传统永久性锚固手段的一些弊端也逐渐显现,为此介绍了一种新型胀裂自锁结构的可回收锚杆,以满足现代矿井支护工业发展的需求。
Bolt support is a kind of widely used technique in geotechnical anchoring.With the development of engineering economy,some disadvantages of traditional means of permanent anchor have been gradually revealed.To meet the demand of modern mine supporting industrial development,this paper introduced a new type of recyclable bolt with burst self-locking structure.
