3. Applications
The T76 hollow grouting anchor system is most commonly used for:
4. Installation Process
4.1 Prepare installation materials including anchor bar, grout, nuts, couplers, bearing plates and any other accessories required.
4.2 Drill borehole to designed dimensions. Diameter, depth, vertical alignment and side-to-side position will be determined by engineering project specifications.
4.3 Place T76 hollow anchor bar into bore hole. Push it down to required depth. You should leave enough exposed anchor bar length to attach the accessories and make any required adjustments.
4.4 Inject grout into the hollow core of the anchor bar. Carefully control grouting pressure and flow to ensure borehole and surrounding void areas are completely filled.
4.5 Install bearing plate, nut and any other accessories onto the exposed end of anchor bar.
4.6 Adjust the anchor to ensure it is in tight contact with the rock mass or structure. This can be done by hand or with mechanical equipment.
5. Corrosion Protection Options
We can provide optional corrosion protection to prolong service life. Options include:
* Hot-dip galvanized per ISO 14 61
* Epoxy coating with bending performance tested to ISO 15 19
* Impact tested per ASTM D27 94
* Adhesion tested to ISO 24 09:2007
6. FAQ
6.1 What is a T76 hollow grouting anchor bar?
A T76 hollow grouting anchor bar is a type of threaded high strength steel ground support anchor used in underground and civil geotechnical projects. It features a hollow core which allows it to be used as both a reinforcement bar as well as a means of injecting grout into the surrounding ground or rock mass.
6.2 What is the difference between T76N and T76S?
The T76S has a smaller inner diameter size and greater cross-section area resulting in a higher load capacity rating. They are typically used in projects where higher strength anchoring is required.
6.3 Where would I use the T76 anchor system?
Typical applications include tunnel support, metro projects, hydropower construction, mining industry, underground caverns, slope reinforcement, foundations and increasing load capacity of aging bridges and tunnels.
6.4 Can I inject grout through the anchor bar?
Yes! Not only does it allow grout to be injected, but helps improve the bond strength between the anchor system and ground/rock.
6.5 What accessories are available for use with the T76 anchor system?
Available accessories include nuts, couplers, bearing plates and other components that are matched to fit the thread system of the T76 anchor bar.
