Helical pile shafts are available in various shapes and sizes. What size you need depends on the loadings and the ground conditions. Generally, the same size helix is not repeat-ed until the largest size available is reached. Helix Anchor Holding Power: A 10-inch screw Helix anchor has approximately 10,000 lb. They are also available in a variety of sizes, finishes, and head designs. Featuring a screw-like design with helices along a steel shaft, these anchors are driven deep into the ground to secure foundations, retaining walls, and anchor the structure to more stable layers of earth The replacement anchor must not exceed any applicable maximum embedment length criteria and either: (A) be embedded to a length that places the last helix plate at least three times its own diameter beyond the depth of the first helix plate of the replaced anchor and meet the minimum torsional resistance criterion; or (B) pass anchor load DESIGN There are many different factors that go into designing and sizing the correct pile configuration for each job. Helical anchors/piles derive their load-carrying capacity through both end bearing on the helix plates and skin friction on the shaft. Screw piles are manufactured using varying sizes of tubular hollow sections for the pile or anchors shaft. In the meantime GUY ANCHORS Two basic types of anchoring systems are used for downguys -- one is the screw type and the other is the “Manta-Ray” type. The projected area is controlled by the size and number of helix plates. At present, maximum working or design loads range between 12. Typically, the soil and holding requirements dictate the number of helices and length of the anchor. Because the CHANCE® Foundation Stabilization System and support uses hydraulic power for driving the underpinning, helical tieback anchors, and Helical SOIL SCREW® Anchors, it is extremely quiet and practically vibration free, thus allowing full use of neighboring buildings during the construction process.
