Patent number: 9512589Abstract: A reusable nose cone device (and related retrieval apparatus) in a hollow helical piling system having a terminal helical anchor are described. The method and system include placing or installing either (i) reinforced concrete piles in situ and/or (ii) grounding systems into the ground—without utilizing a pile driver or an auger, without deconsolidating the surrounding earth and creating spoils (as with an auger), and without unnecessary sacrifice of materials. A terminal helical anchor may be installed through the hollow center of the helical piling system into the ground. The helical anchor may be installed after the removal of the nose cone device. With the system and method, independent and accurate measurement of the anchor's torque may be made and hence complementary “load” bearing, or compression, (or “pull” resisting, or tensioning) capacity may be determined prior to filling the entire pile with reinforced wet concrete.Type: GrantFiled: November 2, 2013Date of Patent: December 6, 2016Assignee: HELI-CRETE ECO-FRIENDLY PILING SYSTEMS, LLCInventors: Kenneth Van Polen, George E.
