Chance Technical Design Manual

CHANCE GROUTFORCE™ DISPLACEMENT PILES DESCRIPTION:

GroutForce piles are made from structural steel meeting the requirements of ASTM A500, A572, A656, and A1018. The displacement pipe casings extend from the perimeter of the central shaft to the outer edge of the grout column. Depth requirements are achieved by adding 5’, 7’, or 10’ extension displacement assemblies and standard extension sections with extension displacement plates. Sections are joined via couplings and structural grade bolts.

The Chance GroutForce screw displacement pile utilizes soil displacement methodology which allows the pile to be advanced into the soil by rotation. Pile sections are comprised of a centralized steel shaft with a patented lead and extension displacement assembly. By design, the pile establishes a cylindrical void which allows a column of grout to be immediately pulled down from a gravity-fed reservoir, creating a grouted, high capacity pile.
