Earth Anchor Systems
Permanent or temporary earth retention systems play a significant role in your project’s cost and schedule. In addition to time and money, an inherent concern with shoring systems is the risk associated with the potential for earth movement. Our earth retention systems involve retaining soil that is subjected to either a natural, unstable slow or an excavation, and often supporting existing, adjacent structures.
We offer different types of earth retention systems that suit a range of soil retention situations. Intech Anchoring has full engineering capabilities to design the most practical and economical soil retention system for your geotechnical conditions.
Intech Anchoring supplies tieback anchors for earth retention systems. Helical tieback anchors are straight rods that strengthen earth retention systems and retaining walls. We rotate and screw them into the ground on one end and secure them to the wall on the other to install them.
Our Magnacore Self-Drilling Anchors combine drilling, placing, and grouting into one step. The AB Chance Helical Tieback System has helical bearing plates welded to a central steel shaft. The load is transferred from the shaft to the soil through these bearing plates. Read more here.
Soil nailing involves installing steel reinforcing bars and anchoring them into the soil. This earth retention system works best for soft soil that’s prone to landslides. The steel bars prevent the soil from sliding out of place.
Intech Anchoring’s soil nails are hollow, threaded steel rods utilized to stabilize slopes and structures at shallow or deep depths. Learn more about the Magnacore Soil Nail wall system here.
Ground screws, also known as soil screws or earth screws, consist of a helical end-bearing plate welded to a central steel shaft acting as a large-scale “earth screw” that is drilled into lateral walls for support.
At Intech Anchoring, we use AB Chance Helical Ground Screws to laterally stabilize soil behind temporary and permanent walls. Read more about AB Chance Helical Ground Screws here.
Earth Retention Systems’ Common Uses
Earth anchors and retention systems are used in a variety of civil engineering and construction projects for many applications, including:
- Supporting an excavation
- Shoring up existing adjacent structures
- Stabilizing a natural or man-made slope
- Bulkhead support and remediation
The design and construction of an earth anchor is often complex due to the soil structure, depth of the groundwater, weather, superimposed loads, seismic loads, and adjacent construction.
Other buildings, construction equipment, and materials located near an excavation result in lateral loads on the retention system. Excavation shoring can be affected by vibrations from traffic, railways, and machines operated in adjacent buildings or construction. Underpinning the adjacent structures reduces the load on an excavation wall and reduces the risk of building settlement.
Earth anchors can be used to provide lateral support of shoring systems. Extreme caution must be used during any shoring excavation, and safety is of the utmost importance. Intech Anchoring understands the hazards associated with earth shoring systems and the importance of safety in those situations. Our many years of experience and technical expertise allow us to provide reliable earth retention and shoring services.
Earth Screw Installation
An analysis of the project site to determine the soil load resistance is often required before installing an earth anchor. Factors to consider include the depth that the anchor should be driven, soil strength and how much moisture is in it, and corrosivity. Sometimes test installations need to be done to determine the best anchor design.
Earth screw installation methods differ depending on the composition of the soil and level of moisture. They are commonly driven into the ground using a drive rod and pile driver. After an impact hammer installs an anchor, the anchor is load-locked.
“Most of the projects I am involved with require a close integration of engineering services and product supply logistics. Without the professional team support I receive from Intech Anchoring, I could not be as successful in this marketplace. The interaction feels more like that of a co-worker than a vendor.”
