Yuen Long South Trial Pile

Project Description

The Project comprises of 4 numbers of trial piles in north-west part of New Territories. 2 test piles being tested for the performance of using new low carbon concrete mix with Ground Granulated Blast-Furnace Slag (GGBS) in typical deep foundation scale & 2 test piles for testing the frictional and bearing capacity of metasedimentary bedrock. 

Construction of trial bored piles. Foundations include 2 numbers of large diameter bored piles constructed by Grab, Oscillator and RCD. Then, filled with new low carbon concrete using high dosage of GGBS. 2 piles constructed by Concentric Drilling and then load tested the metasedimentary bedrock capacity with Osterberg® Cell and kentledge system.

– Ø813mm Bored piles: (a) 2 nos., (b) testing metasedimentary bedrock capacity with Osterberg® Cell and kentledge 

– Ø3000mm Bored piles: (a) 2 nos. (b) testing the performance of new low carbon concrete with high dosage of GGBS
