Helical pile anchor. 75 RCS with one 14” helix) is installed to a depth of 40 ft. Helical Anchors Inc is a manufacturer for Helical Pile, Helical Piers, and Helical Anchors. A helical anchor/pile is an extendable deep foundation system with helical bearing plates welded to a central steel shaft. It will not delve deep into academic theory but will present the writer’s own experiences and solutions to problems involving helical piles and anchors. This guide will attempt to bring the selection and procurement of helical piles and anchors into a more practical point of view. . A helical anchor/pile is a segmented system with helical bearing plates welded to a central steel shaft. Viking is now able to supply the deep foundation and helical anchor industry with the strongest product of its kind in the world. Torque is monitored at 1 ft. • Type 3 - Combo Pile combo pile (Combination Pile) is a helical pile that has both the advantages of square shaft and pipe shaft helicals. Helical Anchors, Inc. Sometimes called helical piers, or helical piles, our anchors can be used for a variety of applications from small soil retention tieback projects to massive towers. With our superior patented Inertia Welding Technology, we provide the strongest piles in the industry. Each helix is attached near the tip, is generally circular in plan, and formed into a helix with a defined pitch. A test Helical Pile anchor (1. A square shaft helical pile will have more axial capacity than a pipe shaft helical pile installed with the same amount of torsional energy into Square shaft helical piles are better at penetrating dense material than pipe shaft helical piles. increments and recorded on Log Sheet 7. • • Type 1 - Square Shaft installation energy. Helical anchors are considered deep foundations and may be used to support any type of load. What is a Helical Anchor/Pile? • A helical anchor/pile consists of one or more helix-shaped bearing plates attached to a central shaft, which is installed by rotating or "torqueing" into the ground. Anchors are used in tension applications and piles are used in compression applications. Load is transferred from the shaft to the soil through these bearing plates. All other diameter helical piles are recommended to be use to 95% of their Ultimate Torsional Strength. recommends only using 85% of the Ultimate Torsional Strength shown above in table A for 2-3/8 to 3-1/2 helical piles. A helical anchor is a steel shaft with one or more helical plates welded around it. A helical pile, also known as a helical pier, helical anchor, screw pile, or screw anchor, consists of a shaft – either a solid square bar or a hollow tubular – with helical plates welded to it. 1 shown on the following page. A combo pile has a square shaft lead section that is better at penetrating dense material and generating load capacity, and is then transitioned to a pipe shaft for the plain extensions where overburden soils are softer and a larger section modulus is CHANCE® Helical piles and anchors are designed, tested, and proven for applications in expansive soils, high water tables, fill areas, and areas where unstable soils require specialized vertical or horizontal support. MacLean helical anchors and piles provide consistent results within a variety of applications. Shaft size and helix configuration are determined by the needed load resistance and soil conditions. xiydzfedofdvhozqgalrysalmkcwpmcuwlouheqpnfgiupjvtojqziudctqbv
