CHD pile performance, Part I:Physical modelling [PDF]

, 2016
The Continuous Helical Displacement (CHD) pile is an auger displacement pile developed by Roger Bullivant Ltd in the UK. It has performance characteristics of both displacement and non-displacement piles due to the nature in which it is installed.

Research on uplift mechanism of screw pile

International Journal of Energy, 2023
This paper uses numerical simulation software to study the bearing characteristics of screw pile with pitch after installation. The selected soil is single layer sandy soil, and the blade is buried in deep burial mode. Based on the numerical simulation results, the vertical bearing characteristics of single spiral pile and ordinary bladeless pile are ...
