Helical Pulldown Micropile, Anchor, SS175, 8/10/12inX 7ft

Helical Pulldown® Micropile Square Shaft (SS 175) Lead Section, 7′ (2134 mm) long with 8″ (203 mm) – 10″ (254 mm) -12″ (304 mm) Helices.
The Helical Pulldown® Micropile is a method used to form a grout column around the shaft of a standard helical anchor/pile. To begin the process, a helical anchor/pile is placed into the soil by applying torque to the shaft. The helical shape of the bearing plates creates a significant downward force that keeps the foundation advancing into the soil. After the Lead Section with the helical plates penetrates the soil, a Lead Displacement Plate and Extension are placed onto the shaft. Resuming torque on the assembly advances the helical plates and pulls the displacement plate downward, forcing soil outward to create a cylindrical void around the shaft. From a reservoir at the surface, a flowable grout immediately fills this void surrounding the shaft. Additional extensions and displacement plates are added until the helical bearing plates reach the minimum depth required or competent load-bearing soil.

Square Shaft Lead Sections are assembled to Square Shaft Extension with through bolt.
The helical shaped plates do not auger into the soil but rather screw into it with minimal soil disturbance
