A field trial of a reusable, hollow, cast-in-situ pile [PDF]

, 2014
This paper describes the concept and field testing of a hollow, cast-in-situ, rotary bored pile foundation 1200 mm diameter and 30 m deep. The aim of the foundation is to allow large-diameter piles to be constructed using less concrete than in an ...
