It can apply high pre-stress to wall rock and decrease the development of roadway separation layers in high limit. The body of this bolt is made of high-strength steel, so it can support strongly and maintain stabilization of roadways.
预应力让压锚杆是针对深井、软岩和受动压影响的大变形巷道而专门设计的一种可延伸锚杆,它可以对围岩施加高预应力,最大限度地减少巷道离层的发展,而且这种锚杆杆体是由高强钢加工而成的,因此在支护时其支护强度很高,能最大限度地维护巷道的稳定;让压锚杆的结构是在高强预应力锚杆的螺母与托盘之间安装一个特制的让压管,能够使锚杆在高支护阻力情况下适应巷道围岩大变形的需要。
