The helical pile shall have the required number of helical blades so as to provide for adequate load carrying capacity. The strength of the helical blades, shaft connections, bracket assembly, and the shaft itself shall be sufficient to develop the 50 kip ultimate bearing capacity and to reach the minimum embedment. Helical piles and bracket assemblies shall be designed in accordance with modern standards for steel construction. Helical piles, and/or casing may be bare steel but the pier cap connection assemblies shall be protected from corrosion by hot-dip galvanizing per ASTM A123 or A153, as applicable.
Bolts used to join helical anchor and helical pile sections at the shaft connections shall be the grade and size specified by the helical pile manufacturer. All helical pile bolts shall be securely snug tightened.
569.03 Grout Requirements. Grout mix shall be a neat cement grout with a water/cement ratio W/C= 0.40 – 0.5. The final grout shall have a minimum 28 day compressive strength of 3,000 psi (AASHTO T 106).
Water for mixing grout shall be potable, clean and free from impurities, which may be detrimental to grout or steel. Potable water shall be available in quantities sufficient to mix grout and for equipment clean-up.
Cement for grout shall be Portland cement conforming to ASTM C150 Type I or Type II. Pre-packaged, non-shrink cement grouts shall be subject to the review and acceptance of the Contracting Officer, and shall conform to the requirements of ASTM C1107.
Construction Requirements
569.04 Installation Equipment. Each helical pile shall be advanced into the ground by application of rotational force using a hydraulic torque converter. Installation equipment shall include a direct means of determining the installation torque being applied to the helical anchor and helical pile.
569.05 Installing Helical Piles. Manufacturer’s recommendations should be followed regarding the torque capacity relationship for the particular helical piles. The number and size of blades shall be determined by the Contractor so as to achieve the required ultimate bearing capacity for the soil conditions at the site.
Helical piles shall be advanced into the ground until the required torque is achieved to accommodate the ultimate bearing capacity plus an additional distance to ensure proper embedment. For the helical piles, the embedment length shall be achieved by continuing advancement while maintaining or exceeding the required torque for a distance of at least three (3) feet.
Constant normal pressure shall be applied while screwing helical piles into the ground. The pressure applied shall be sufficient to ensure that, during each revolution, the helical anchor and helical pile progress into the ground a distance equal to at least 80% of the blade pitch. Rate of helical pile rotation shall not exceed 20 revolutions per minute.
569.06 Grout Mixing. Batch grout at a water/cement ratio of 0.4 to 0.5, Always place water before cement into mixer. The grout shall be mixed for a minimum of two minutes, or as directed by the cement supplier. Thereafter, continuously agitate grout in the storage tank. Inject grout within 45 minutes after the water is initially added to the cement by Tremie to the bottom of the casing. When the ambient temperature is 90 degrees Fahrenheit, or higher, grout shall be injected within 15 minutes of mixing.
Do not allow grout to exceed a temperature of 90 degrees Fahrenheit. Add shaved ice to the water before mixing cement to control the grout temperature.
| 569.07 Construction Tolerances. | Centerline of piles shall not be more than 1 inch from indicated plan location or ¼ inch from vertical elevation indicated. | ||
