Hollow Bar Micropiles - Phoenix Foundation Company

Hollow Bar Micropiles Hollow bar micropiles are small diameter bored, cast-in-place composite piles in which the applied loads are resisted by steel reinforcement, cement grout and frictional grout-to-ground bond. In most ways hollow bar micropiles are like traditional micropiles, but there are some key differences. The bar itself acts as the drill rod and is []Hollow Bar (Hollow Tube) Piles | Foundation Professionals steel helical hollow anchor barHollow bar piles, accepted by the FHWA in the Micropile Design and Construction Guidelines Manual, are gaining popularity for micropile applications.

ICC-ES Evaluation Report ESR-3982 - Helical Anchors

The Helical Anchors helical foundation systems consist of a lead shaft section with one or more helical-shaped steel bearing plates (or helices), extension shaft section(s), couplings that connect multiple shaft sections, and a bracket that allows for attachment to the supported structures. The IDEAL® Square Shaft and Round Shaft Helical Piles Most square shaft helical piles are available in sections of 3, 5, 7, and 10 feet long. Square shaft helical anchors are the best choice for many tension applications and some compression applications such as sand, hard soil layers, and trash sites. Square shaft helical piles can be more versatile than pipe piles with more sacrificial steel.Products Section | HelifixHelifix Products.
