Combination (SS to RS)

 

Chance Helical Transition CouplerChance® Helical Transition Coupler
Adapts Type SS to Type RS Pile Shafts

The Type SS/RS Combination Pile is used mainly in compression applications in areas where soft/loose soils are located above the bearing strata (hard/dense soils) for the helices. The Type RS material with a much greater section modulus will resist columnar buckling in the soft/loose soil. The Type SS material will allow adequate penetration of the helices into the hard/dense material without “spin-out”, i.e., loss of thrust of the helices in the soft/loose material.

The design should be prepared by a Registered Professional Engineer with suitable soil information.
