Friction bolt
Functions
Friction bolt (Split sets) is a frictional ground support system.When friction bolt is inserted into drilling hole with smaller diameter,
the slot partially closes and bolt diameter is compressed, which creates radical forces on rock roof surface along the whole length and firmly holds the rock.¥ 0.00立即购买

Swellex rock bolts
In most cases, TITANEX bolts are designed for temporary support for 2-3 years. So no special surface treatment is needed. However, when a longer service life is required, the zinc-galvanized steel pipe is selected because it has a rust-preventing ability comparable to that of stainless steel, and is less expensive.¥ 0.00立即购买

管缝式锚杆
锚杆是当代煤矿当中巷道支护的最基本的组成部分,他将巷道的围岩加固在一起,使围岩自身支护自身。现在锚杆不仅用于矿山,也用于工程技术中,对边坡,隧道,坝体进行主体加固。锚杆作为深入地层的受拉构件,它一端与工程构筑物连接,另一端深入地层中,整根锚杆分为自由段和锚固段,自由段是指将锚杆头处的拉力传至锚固体的区域,其功能是对锚杆施加预应力。¥ 0.00立即购买

水力膨胀锚杆
水胀式锚杆是一种由外径大于锚孔孔径的无缝钢管加工制作成的双层凹形管状杆体。
水胀式锚杆又称水力膨胀锚杆,它由端套、挡圈、注液端、托盘等配件构成,把该钢管放入锚杆孔后用高压水使其膨胀,在膨胀过程中,水胀式锚杆产生永久变形,锚杆管壁与锚杆孔的不规则孔壁完全贴合,由于沿整个锚杆全长产生了摩擦力和自锁力,从而加固了岩体。¥ 0.00立即购买
