Product Description

 Product Description

Hollow anchor bar means a rod that transfers the structures or geotechnical load to a stable rock formations, anchor bolt consists

 

of bar, drill bit,

 

coupling, plate, grouting stopper and nut.

 

Widely used as an efficient anchoring means, in tunnel pre-support, slope, coast, mine, water conservancy projects, building foundation, roadbed reinforcement and geological diseases treatment such as landslip, crack, sink age. It's irreplaceable in narrow construction environment.

 

Hollow anchor bar is made of seamless tube with high strength.

Features of Hollow Grouting Anchor Bar:

• Fits standard Boomer, ROC and Mustang rigs.

• 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

Advantages and Characteristics

 

:

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.

10 TIPS YOU SHOULD CONSIDER WHEN ...

6.Different anchor bits are available for different ground conditions.

7.Duplex anti-crossion prosess ,hot-dip galvanized and epoxy coating system.

We can provide customer-required Standard,Specification,Material,
Application of Carbon steel tube,Alloy steel tube and their machined products etc. We have ten years of industry experience, the annual output of the factory is 250,000 
tons, non-standard steel tube, super thick wall steel tube, alloy steel tube, super long steel tube, fixed size steel tube are our production advantages.

Our upgraded anchor factory. Compared with traditional anchor production factories, we have the following advantages in the supply chain process:
First, the advantage of raw materials. The raw materials of traditional anchor factories are precision seamless steel pipes, while our raw materials are round steel. Therefore, our production process covers round steel hot perforation, pickling, precision cold rolling, straightening and warehousing, and anchor rolling.
Second, product quality control advantage, all processes of anchor production in our factory are internally controllable and traceable.
Third, cost advantage. We have more than 20 years of seamless steel pipe production experience. In terms of raw material procurement costs, the cost control of each process can be more reasonable.
Fourth, the delivery time advantage stems from the reasonable process layout of our factory. Compared with the traditional anchor factory's delivery time of more than 30 days, our delivery time can be shortened to less than 20 days.
