To install each tieback a hole is cored through the seawall from the water side Then a helical tieback anchor is inserted into the cavity and rotated into the soil behind the seawall with a hydraulic anchor drive The Helical plates fused to the square shaft make the tieback perform like a gigantic screw Screw piles and helical anchors are generally limited to installation in soils that have a maximum grain size less than about 60 of the pitch of the helices For a typical pitch of 3 in this means a maximum grain size of about 1 3⁄4 in or medium gravel Installation Equipment Call 805 526 1383  We offer a complete line of helical pile installation equipment produced by the nation s leading manufacturers Our specialty line of tight access helical installation equipment is tailor made to install your piles in even the tightest access conditions Please Modular U S Patent 6 817 810 HELI PILE 174 installers asked for adaptability and adjustability From this need arose the development of the patented Modular Helical Pile and Tieback With the Modular Helical Pile you can make any 2018 2 21 nbsp 0183 32 These anchors are long steel poles that have screws which can be withdrawn and reused Helical tiebacks are screwed into the soil around the foundation the anchor then helps stabilize and support bowing or leaning
