产品简介

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

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 rockin 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.

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.
