Driven Piles are of various shape make and sizes, these consist precast concrete, round steel casings, tubular steel casings, steel H sections, composite piles and timber piles.
Depth - depending ground conditions.
Hydraulic and Air powered Impact Hammers ranging from .6 tonne to 14 tonne (ram block weight).
Hydraulic Vibratory Hammers from 5 tonne to 12 tonne.
They are a cost effective piling technique and can be used in a variety of soil conditions. Piles can be driven to depths of 50 metres depending on soil conditions and carry high individual loads or can be grouped together for heavier loads. Driven Piles takes away the requirement to remove spoil from site and can therefore be ideal for working in contaminated areas.
Avopiling have hydraulic impact hammers that can drive precast piles. The most significant accomplishment we have achieved is driving of 550 octagonal precast piles and steel tubes 1.55m in diameter to a depth of 39 metres.
In most cases driving of steel casings on certain ground conditions would require us to utilise the hydraulic impact hammer and or vibratory hammers ranging from 6 tonne to 14 tonne (ram weights).
The benefits of driven piling systems are the following:
The project is located in the Gold Coast region under the management of Queensland Rail. The project involves 8.2 kilometers of rail tracks comprising of 8 bridges. Golding Contractors was selected to undertake the rail duplication.
Avopiling QLD Pty Ltd was awarded the contract to construct the foundation piles of the 8 bridges on the project. The piles for Bridges 3, 4 and 5 were built drilled using temporary casings and polymer drilling fluid. Another section of Bridge 5 foundations were change to 84No 550 octagonal driven piles to lengths ranging from 18 to 25.00 meters. The bored pier foundations are made up of 4No-1200mmØ, 38No-1350 mm, 22No-1500mm and 4No-1800mmØ to drill depths reaching 29.00 meters.
