锚索测力计在锚杆支护中的应用

Application of Anchor Dynamometer at Bolt Support

锚索的预应力在锚杆支护系统中起着决定性的作用。而锚索在施加预应力过程中由于受锚索材质及巷道条件等因素的影响,存在一定量的预应力损失,严重影响了锚网索支护效果。用测力计可以准确获取预应力损失值,然后通过超张拉达到锚索应需预紧力。

The prestressed anchor played a decisive role in bolt support system. And in the process of prestress anchor by anchor cable material and conditions of the influence of factors, there is a certain amount of prestress loss, serious impact on the bolt - mesh - an- chor supporting effect. Dynamometer can get accurate with the loss of prestress value, and then through the super tension to anchor ca- ble you should be preloaded force.
