Using CSM Equipment for Deep Soil Mixing
DSM is frequently used in Europe and Asia to improve soft compressible clays where traditional methods, such as surcharging and wick drains are not feasible, due to either stability reasons or time and/or space constraints. Cutter Soil Mixing is a recent method for DSM and has been used on a projects in Australia for settlement control of large oil tanks, retaining walls and shafts. In this presentation the CSM equipment and methodology will be discussed
Piling and Soft Soil Treatment – Gateway Upgrade Project
The $1.88b Gateway Upgrade Project is a Queensland State Government initiative being delivered by Queensland Motorways, with design, construction and maintenance by Leighton Abigroup Joint Venture. The project involves 20 kilometres of Gateway Motorway upgrade between Mt Gravatt-Capalaba Road in the south to Nudgee Road in the north. Significantly, the project includes construction of a second Gateway Bridge, which will provide a new Brisbane River crossing, as well as improved travel times and safety for motorists.
This Project is now well underway with over 14,000 piles installed over the past 15 months by four different foundation companies. In addition to the vast amount of piling this project also boasted the application of the Osterberg Load Test system for the first time in Australia.
A project overview incl. ground improvement systems, piling, and pile testing will be presented.
