Helix Power Driven Anchor
A helix power driven anchor is used to provide an anchor point at the ground line for foundations and different types of structures. It acts as part of the support system, increasing stability and torsional strength for a firm and secure foundation.
Structures or foundations built on weak soil conditions may require additional reinforcement to distribute structural loads and ensure adequate resistance to lateral forces. Helix power driven anchors are an ideal solution in such cases since they are easy to install and offer increased torque and bending strengths.
The versatile design of these anchors makes it possible to extend their depth by using extensions. They have helical blades that are tapered to ensure that the anchor can penetrate even dense soils with ease and embed itself firmly in the ground for a secure and stable anchor point.
The structure of the helix power driven anchor can vary depending on type. Socket-type anchors have a socket for anchoring rods with helical blades attached to the body for easy installation. They are ideal for semi-permanent installations and dense soils where shaft type anchors may have difficulty penetrating.
Shaft-type anchors have a cylindrical rod body with tapered helices attached. Due to their superior load bearing capacity, this type of power driven anchors are ideal for heavy duty applications and permanent installations.

Frequently Asked Questions (FAQs)
What is the main function of power-driven anchors?
Power driven anchors are used to increase torque and bending strength to create a stable and secure foundation for structures, cables and various types of constructions. They are used in areas with tough soil conditions where they effectively embed into the ground creating a stable anchoring point.
How do I choose the right earth anchor for my project?
The most effective anchoring solution for your project will depend on the project load requirements, the type of soil or ground conditions, size of rods and specific application. For instance, square shaft power driven anchors have a better load bearing capacity compared to socket-type anchors so they are better for heavy-duty applications.
How are helical power driven anchors installed?
Power driven anchors are screwed into the soil by applying pressure on to the anchor to push into the ground. The tapered helical blades of the anchor help to penetrate into the ground even in dense and rocky conditions. Hydraulic machines such as a Kelly bar adapter are typically used for the installation. Extensions can also be used to extend the depth of the power driven anchor.
Can helical power driven anchors be repositioned?
Yes, helical power driven anchors can be uninstalled and reinstalled in a different position. However it is important to check for mechanical damage or wear before reinstalling to ensure that the torque capacity and stability of the anchor is still intact.
