45# S45C 1045 C45 seamless steel pipe for anchor rod
Hollow Drilling Mining Rock Grouting Anchor Bolt 1, Hollow Drilling Mining Rock Grouting Anchor Bolt consists of hollow core with continuous hot-rolled outside thread
40Cr 5140 alloy steel pipe for anchor rod
2, Hollow Drilling Mining Rock Grouting Anchor Bolt can application as injection anchor without casing, especially for non-stable boreholes
full threaded steel self drilling rock bolt / hollow anchor bar / anchor rods The Self Drilling Anchor system is comprised of a hollow threaded anchor bar with a sacrificial drill bit that performs drilling, anchoring and grouting in a single operation. Self drilling anchor system is mainly used in slope stabilization, tunneling pre-support, foundations with micro piles etc projects. Advantages and Characteristics as below: 1. No casings required, because anchor bars can be drilled into loose soils without needing casings to support the boreholes. 2. Fast drilling and installation, because drilling, installation and grouting are in a single operation. 3. Both rope threads and trapezoid threads are robust and ideal for rotary-percussive drilling and ensuring a high level of bond with the borehole gout. 4. The hollow core not only serves for flushing during drilling, but also for grouting after drilling. 5. Continuous threads ensure the bars can be cut and coupled at any point, or extended. 6. Different anchor bits are available for different ground conditions. R thread anchor bar or called rock bolt, soil nail, which is a kind of threaded hollow bar, bar surface with an rope thread according to ISO 10208 & 1720. It was firstly invented by MAI on 1960S to solve the low construction speed on complicated underground works, nowadays; it is very popular all around the world.
