Chance helical pier design manual

STEEL HELIX PIERS PART 1: GENERAL 1.1 DESCRIPTION: A) The work of this section consists of furnishing and installing steel helix piers manufactured by MacLean/Dixie Anchoring Systems, Birmingham, Alabama. B) Steel helix piers shall be designed and installed to resist the unfactored design loads as shown on Sheet S-____. A Potentially Uneven Playing Field has been Created for the Helical Pile Industry by the International Code Council Evaluation Services (ICC-ES™) On May 1 this year, ICC-ES™ staff issued ESR-2794 to Hubbell Power Systems® - the parent company of A.B. Chance® (Chance®). ESR-2794 certifies two Chance® products - SS5 and SS175 helical Helical Pile Design Software. Ram Jack® provides free engineering software for use in designing and implementing helical piling. Ram Jack Foundation Solutions™ Software was designed by engineers, with engineers in mind. loose soils above the bearing strata. The Helical Pulldown® Micropile series is also used in applications similar to those requiring the use of the Type SS-RS combinations. Please refer to the CHANCE Technical Design Manual for: Complete list of mechanical rating and section properties of the central steel shafts Product Feasibility CHANCE® Helical Piers have 11? 2" to 21?? 4" solid square shafts or 31? 2" pipe shafts with helical plates 8" to 14" in diameter. For more details, see Bulletin No. 01-0502 and Technical Manual 01-9601. The CHANCE® HELICAL PULLDOWN® Micropile constructs a grout column around the shaft of a helical pier for sites with weak Chance Helical Piers. Helical Piers contain Helices, or helical flights, that serve as end bearing plates for the weight of your home. These flights are welded to a central steel shaft. The helical shaft essentially acts as a screw that is rotated into the soil. BEARING AND FRICTION DESIGN CAPACITY FOR HELICAL ANCHORS AND PILES Original Author: Gary L.
