3 ATLAS RESISTANCE PIERS The Atlas Resistance Pier is an assembly of structural steel components that includes a steel bracket assembly attached to the foundation or slab, which is then mounted on a steel pier that is installed to bedrock or firm bearing stratum. The lead pier starter section includes a unique friction reduction collar that tends to reduce skin friction on the pier pipe during installation. CHANCE Civil Construction offers a broad range of pier pipe sizes and remedial repair brackets for both foundation underpinning and slab underpinning applications. This section will discuss those products in detail along with their capacity ratings.

10 CHANCE HELICAL ANCHORS/PILES INTRODUCTION A helical anchor/pile is a segmented deep foundation system with helical bearing plates welded to a central steel shaft. Load is transferred from the shaft to the soil through these bearing plates. Central steel shafts are available in either Type SS (Square Shaft) series or Type RS (Round Shaft) series. The Type SS series are available in 1-1/4 to 2-1/4 square sizes. The Type RS series are available in 2-7/8 to 4-1/2 diameter sizes. Type SS-RS combinations are also available for compression applications in soil conditions where dense/hard soils must be penetrated with softer/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. For a complete list of mechanical ratings and section properties of the central steel shafts, see Tables 7-3, 7-4, and 7-5 for Square Shafts and Tables 7-6, 7-7 and 7-8 for Round Shafts in this section. Refer to Section 3, Product Feasibility and Section 6, Installation Methodology for guidelines on the proper shaft selection based on application, soil conditions, site accessibility, etc. Segments or sections are joined with bolted couplings. Installation depth is limited only by soil density and practicality based on economics. A helical bearing plate or helix is one pitch of a screw thread. All helices, regardless of their diameter, have a standard 3" pitch. Being a true helical shape, the helices do not auger into the soil but rather screw into it with minimal soil disturbance. Helical plates are spaced at distances far enough apart that they function independently as individual bearing elements; consequently, the capacity of a particular helix on a helical anchor/pile shaft is not influenced by the helix above or below it. LEAD SECTION AND EXTENSIONS The first section or lead section contains the helical plates. This lead section can consist of a single helix or up to four helices. Additional helices can be added, if required, with the use of helical extensions. Standard helix sizes are shown in Table 7-2. The helices are arranged on the shaft such that their diameters increase as they get farther from the pilot point. The practical limits on the number of helices per anchor/pile is four to five if placed in a cohesive soil and six if placed in a cohesionless or granular soil. Plain extensions are then added in standard lengths of 3, 5, 7 and 10 feet until the lead section penetrates into the bearing strata. Standard helix configurations are provided in the product series tables in this section. Note that lead time will be significantly reduced if a standard helix configuration is selected.
