Installation Of Bored Pile Casings Through An Asbestos Tip By Rotary Displacement
Organization: Deep Foundations Institute
Jan 1, 2000
A rotary displacement method was used to install permanent steel casings for bored piles through an asbestos tip. This method was chosen in preference to alternative driven systems because it was quieter and more versatile if obstructions were encountered. New equipment was designed and made specifically for the project, and stringent health and safety regulations had to be observed.
