管缝式锚杆         产品介绍

Seam pipe bolt Product introduction

管缝式锚杆又叫“岩石摩擦稳定器”

缝管锚杆是专用性很强的支护用品  

井下涵洞顶板及其它工程支护使用的先进材料  

工艺很简单
使用方便
很强的膨胀力

管缝式锚杆是一种全长锚固

New anchor active reinforcement of surrounding rock

It is a solid part of high strength steel to a longitudinal slit

主动加固围岩的新型锚杆

它立体部分是一根纵向开缝的高强度钢管

When installed in the drill hole is slightly smaller than the diameter,

friction can be immediately in the full scope to the pore wall applied radial pressure and stop the rock slide

当安装于比管径稍小的钻孔时,可立即在全长范围内

对孔壁施加径向压力和阻止围岩下滑的摩擦力

Add anchor pallet pallet load bearing capacity, so that the

surrounding rock in the three direction stress state of rock solid, and realize.

加上锚杆托盘托板的承托力,从而使围岩处于三向受力

状态,并实现岩层稳固。

In the blasting vibration of surrounding rock anchor shift under such circumstances, the late anchoring force increases significantly,

when the surrounding rock has a significant displacement, anchor does not lose its supporting force, it has better properties than expansion shell bolt.

在爆破振动围岩锚移等情况下,后期锚固力有明显

增大,当围岩发生显著位移时,锚杆并不失去其支护抗力,它比涨壳式锚杆有更好的特性。

管缝式锚杆         产品特点

Seam pipe bolt Product features

管缝式锚杆具有制造工艺简单,使用方便

在井下锚喷支护中具有锚固力强、抗拉力大,很强的膨胀力,使整个顶板成为一体

Seam pipe bolt has the advantages of simple manufacturing process, easy to use

In the underground shotcrete has a strong anchor, anti pull large, there is a strong expansion of power, so that the whole roof into one

选择一根管缝式锚杆需要知道什么?

Choose a slotted bolt needs to know what?

首先管缝式锚杆是一头粗一头细的管状杆体,

选择一根锚杆,

需要知道锚杆的粗头直径,

杆体长度,杆体壁厚。

然后配套相关托盘使用。

Firstly, the pipe joint anchor rod is a coarse to fine tubular rod head,

Choose a bolt,

Need to know the thick head bolt diameter,

The length of the rod, rod wall thickness.

Then the relevant supporting the use of pallets.
