Product Description

Self Drilling Hollow Bar Micropiles Steel Anchor
Self drilling anchor bolt system is mainly used for tunnel and underground engineering, slope engineering, ground and foundation engineering. It can be used for pre-construction support and can effextively enhance the stability of soil and rock mass.

Anchor bolt 

Anchor bolt means a rod that transfers the structures or geotechnical load to a stable rock 

formations, it consists of rod, drill bit, coupling, plate, grouting stopper and nut. It has been 

widely used in tunnling, mining, slope stabilization, tunneldiseases treatment and roof supporting 

of undergroundworks. It is for loose ground(clay, sand friable etc.) Hollow anchor rod is made of 

seamless tube with high strength.

 

Features of hollow grounting anchor bolt 

• Particularly suitable for difficult ground conditions.  

• A high rate of installation since drilling, placing and grouting can be performed in one single operation.  

• Self drilling system eliminates the requirement for a cased borehole.  

• Installation with simultaneous drilling and grouting possible.  

• Easy installation in all directions, also upwards.  

• Suitable for working in limited space, height and in areas of difficult access.  

• Simple post grouting system. • Hot-dipped galvanizing for corrosion protection  

 

Applications in Tunneling & Ground Engineering   

• Radial bolting  

• Slope stabilization  

• Forepoling  

• Micro injection pile  

• Face stabilization  

• Temporary support anchor  

• Portal preparation  

• Soil nailing 

 

Surface Treatment:

  • Anti-rusty Oil
  • Painting
  • Hot dip galvanizing (HDG)
  • Epoxy
  • HDG + Epoxy

The Self-Drilling bolt is a fully threaded hollow bar that initially serves as a drill rod, utilizing a lost bit. The thread is made to comply to ISO 10208. For use in unconsolidated ground or other difficult ground conditions.
Self Drilling Hollow Bar Micropiles Steel Anchor
• Excellent for spiling (fore-poling)
• Bolt is drilled in and grout is pumped through the center hole with pumpable resin or cement grouts
• The couplers are designed to exceed the ultimate load of the bar by 20%. The couplers are designed to minimize the loss of drill energy
• Several drill bits are available. Most widely used is the EXX Tungsten carbide chisel bit
• Standard length is 3 m (9 ft -10 ft) - Longer lengths are available: 4 m, 6 m
• Galvanized option under ASTM A123
