摘要
树脂锚杆应用于锚固工程时,需要使用大量的药卷,回收率很低,并且当锚孔中存在煤岩碎渣时,锚杆体很难插入锚孔孔底,容易造成假性施工,带来许多安全隐患。因此,设计了可回收楔式锚杆,降低了费用,避免了假性施工,提高了回收率。
When resin bolt can be used in anchoring engineering, it requires large volumes of drags and has a low recovery. When the bolt holes has the cinder of coal and rock, it is difficult to insert bolt into anchor hole which can easily form the pseudo construction and bring a lot of potential problems. Therefore, designs reclaimable wedge bolt which can reduce the cost, avoid false construction and increase the recovery.
