Retractable nose cone system and method for forming reinforced concrete pilings and/or an electrical grounding system

摘要

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.

主权项

1. A method for installing a piling, comprising:
providing a piling, the piling comprising a pipe; sliding a detachable nose cone device through a coupler section of the pipe; coupling the detachable nose cone device to the coupler section of the pipe by activating a first set of one or more locking mechanisms that are part of the detachable nose cone device; applying torque to the pipe in order to rotate the pipe, coupler section, and detachable nose cone device into ground with the pipe engaging the ground; and inserting a detachable picker device into the pipe; removing the detachable nose cone device from the coupler section and from the pipe by deactivating the first set of one or more locking mechanisms and by coupling the nose cone device to the detachable picker device, wherein at least the pipe remains in the ground after torque has been applied to the pipe.
