Underground Mine & Tunnel Support with Hollow Anchor Rock Bolt System
In the recent 20 years, many huge projects in mining, high speed railways, dams and enpro plants have been built in China.
As an effective ground support solution, Self Drilling Anchor Bolt System has been widely used in consolidation, slope stabilization, roof control, soil nail and piling.
Benefiting from its easy handling and availability, self drilling anchor system has been applied in the worldwide.
And there are several popular systems like CTS/TITAN, MAI/MINOVA, DYWIDAG/DSI, etc. These systems are similar more or less, and many other manufactures make corresponding threaded hollow anchors to supply.
Naturally the quality is different between different product origins. Even many of them can't meet the basic requirements (e.g. ductility, elongation Agt, yield load, ultimate load, and bond force.).
Though the price might be lower, do you have the confidence to use it in civil construction?
We highly recommend that people should take the performance of a finished hollow bar anchor seriously.
