The soil capacity beneath a communications tower was shifting, and the structure needed reinforcing. A partner reached out to Intech Anchoring Systems to engineer a solution.
One of the biggest challenges was that the contractor was inexperienced with reinforcing towers. The tower’s location was in a limited access area, and the significant amounts of electrical equipment made for a difficult project.
Intech’s expert engineers decided that the following solutions were best for the project:
Intech assisted with equipment rental, engineering services, and material delivery to reinforce the communication tower successfully. The contractor was impressed by our training services and our frequent communication both during and after installation.
SDAs are ideal bolting solutions for poor ground conditions, such as gravel, silt, and clays. They should be considered the primary solution for projects.
SDAs are most commonly used to stabilize soil formation. Contractors favor SDAs for weathered ground conditions because they offer a fast and straightforward installation process.
SDA micropiles are composed of injected grout with an anchor rod as a steel reinforcement. They’re installed in sites with limited space using light drilling equipment and are suitable for tension and compression loads.
SDAs are economical for reinforcing tunnel circumferences and providing advanced roof support for tunnel excavation in overburdened rock conditions.
The SDAs offered by Intech are made from the following items:
The anchor rods feature a hollow interior for flushing, simultaneous drilling, and grouting. They’re manufactured from API standard thick wall steel tubing and cold rolled to a standard rope thread profile. By rolling the anchor rods, the crystalline structure of the steel is refined, which leads to increased yield stretch and a more durable drill rod. The anchor rod’s standard rope thread produces an excellent bond between the rod and grout and enables a better connection to the drilling rigs.
With a patented design that allows for direct end-to-end energy transmission, the extension coupling reduces losses and maximizes energy performance at the drill bit. All bars are precisely chamfered, which allows the bar ends to have direct contact.
The bearing plates are forged to steel plates and feature a center hole, which allows for seven degrees of articulation in all directions.
Hexagonal nuts are manufactured using high-precision steel with chamfered edges on both ends and tempered to meet the strictest demands of anchor specifications for daily use. All nuts provided by Intech exceed the highest standards for strength.
Intech uses analytic evaluations to develop a hot-dip galvanizing corrosion protection anchor that limits the corrosive process. Our full range of SDAs and accessories are available with corrosion protection.
Coupling boxes are ideal for high-wear locations because they’re made from thick-wall steel that’s machine and case hardened. Installers apply a locking torque to the permanent joints of the coupling box to avoid release when anchor bars are added.
Rotary percussion with a hydraulic or air hammer is the preferred installation method. Intech provides a full range of shank adapters for different hammers.
Grouting is done after using standard flushing materials by connecting the grouting hose from the pump to the anchor bar, and is removed once the process is complete.
