Short description
Specifications
Product Ecology Uses CNC Torch Table to cut the helix. Uses Welder to attach helix to shaft. Cuts shaft with CNC Multimachine. Uses 3D Printing for wire arc additive manufacturing of joints. Uses Hot Dip Galvanizing for final coat (not included in the GVCS). Uses Universal Rotor-based helical pile driver with LifeTrac open source tractor, with Power Cube hydraulic takeoff.
License OSHWA and OSI compliant. CC-BY-SA-4.0 International, GPLv3, DIN SPEC 3105.
Module 1 Helix is CNC cut with 5 axis CNC torch table to get a leading edge.
Module 2 Shaft is standard 2" pipe, 0.19" wall.
Construction Connector is WAAM 3D-Printed.
Productivity Allows for 1 day-builds of entire foundation systems, with 5 minute auger time per pile.
Completion Status
Design phase as of 9/16/20. See also Status of Completion.
