fabricated to your specifications upon request. ECP helical anchors, also known as helical piers, screw piers, screw anchors and torque anchors are ideal for deep foundation support applications where there is a need to resist both tension and axial compressive forces. Examples of these include expansive clay soils, solar panel foundations,
Bolt Torque Chart - Portland BoltTorque has been converted into ft/lbs by dividing the result of the formula by 12 All calculations are for Coarse Thread Series (UNC). Grade 2 calculations only cover fasteners 1 4 - 3 4 in diameter up to 6 long; for longer fasteners the torque is reduced significantly.
helical tieback anchors. The configuration of the specified ECP TAF-175-84 08-08-08 Torque Anchor consisted of three 8 inch diameter helical plates attached to a 1-3/4 inch solid square shaft that measured 7 feet long. The design called for two rows of four tieback anchors. The first

DESIGN, INSTALLATION AND TESTING OF HELICAL 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. Each helix is attached near the tip, is generally circular in plan, and formed into a helix with a defined pitch. Helical anchors/piles derive their load-
ECP Helical Torque Anchors are a part of the complete product line of helical piers, steel piers, and foundation repair products manufactured by Earth Contact Products, LLC, a family-owned company based in Olathe, Kansas.The company was built upon the ECP Steel Pier, a fourth generation end bearing steel mini-pile designed and patented by Don May.
HELICAL PILES ANCHORSA HElICAl PullDoWN®Micropile is a square shaft helical foundation or anchor that has the plain ex- tension sections encased in a small diameter grout column, typically 5 7 in diameter. Pipe shaft heli- cal piles can also be encased in a grout column, but that is less common.
HELICAL PILES ANCHORSHELICAL PILES ANCHORS II. DESIGN REQUIREMENTS A. Shaft Type of Helical Pile/Anchor There are 4 basic types of helical piles available. The following is a brief summary of the 4 different types of helicals. Type 1 - Square Shaft Square shaft piles are more efficient than pipe shaft helical piles in regards to capacity derived from

HELICAL TORQUE ANCHOR. ECP Helical Torque Anchors can be installed prior to the start of foundation construction to negate the effects of the adjusting soil conditions. The piles are installed at intervals between the footing forms and tie into the steel grid-work prior to pouring concrete.
Helical Torque Anchors Technical Design ManualThe standard pitch of all helical plates is three inches, which means that the anchor advances into the soil a distance of three inches during one revolution of the shaft.
Installation Guidelines and Testing ProceduresHydraulic Torque Motors Helical Torque Anchors are usually installed with a hydraulic motor and reduction gear box assembly. Some motors offer a two speed gear box, wh ich allows the installer to increase the advancement the Torque Anchor through
