[info]The Komatsu excavator is used for setup works for pilling rigs or light weight pile driving and anchoring or pining[/info]
We use this for:
- Earth works
- Pier drilling
- Sheet pilling
- 8 m light weight steel / polymer sheets
- Or 12 m side mounted hammer
- Ground anchoring pins and screw anchors
[info]The Woltman 90DR rotary drilling rig has an operating weight of approx. 102 t.[/info]
It is ideally suited for:
- Drilling cased boreholes ( installation of casing by rotary drive or optionally by hydraulic oscillator – both are powered by the drilling rig )
- Drilling uncased deep boreholes that are stabilised by drilling fluid
- Drilling boreholes with long hollow stem augers (CFA system), with or without kelly extensions
- Special drilling systems, such as FOW piles, double rotary head drilling (“cased CFA system”), displacement piles, soil mixing system (CSM and SMW)
Drilling processes with standard equipment
- Sheet piling up to 36m
- CFA drilling (pre-equipped with hydraulic and electric installations) up to 34m
FDP Full-Displacement-Piling (pre-equipped with hydraulic and electric installations) up to 45 m
- Double rotary head drilling up to 30m
Tugun, Gold Coast, Qld
Part of the construction of the Gold Coast Desalination Alliance’s plan for a Desalination Plant as a solution to the millennium drought, Ausipile was engaged to construct a vinyl sheet pile wall to provide methane gas cut off wall.
Prior to the start of the sheet piling, in 2008, Ausipile undertook the installation of pilot trials for the Alliance to ensure the installation methodology proposed could be confidently re-produced in bulk on site.
The project involved the pre-drilling and installation of interlocking CL9000 C-Loc vinyl sheet piles, with the use of custom made steel driving mandrels to protect the vinyl pile during installation. Piles were installed with a sacrificial custom pile toe clamping plate and driven through fill material, old landfill, and indurated sand.
In addition to the installation of the vinyl sheet piles, due to the ground conditions and topography in the remediated landfill site, localised dewatering was also undertaken by Ausipile where required.
To ensure efficiency and performance on site, 2 piling rigs were allocated to the project, working simultaneously on 2 work fronts (pre-drilling and sheet pile installation).
The project was a huge success, and the client was extremely pleased with the product and quality of the installation.
19 – 27 Onslow Street, Ascot
Design and construction of 450mm diameter open bored soldier piles for a single level basement using our rotary drilling rig BG 15 H, as well the design and construction of 600mm diameter foundation piles for the crane base.
4 Storey Residential – 578 Sherwood Road, Sherwood
Design and construction of perimeter Ø600 Cased Soldier Piles for a 2-level ramping basement.
Construction methodology included pre-drilling through an alluvial cobble bed layer, backfill, and finally casting in-situ piles.
Capping beam details, and temporary bracing struts were designed, supplied and installed by Ausipile.
Albany Creek Road, Aspley
Extension of portal frame structure in Shopping Centre.
Design and construction of CFA Foundation piles ranging in diameter sizes from 470mm to 750mm using custom made attachments for our PC270, and BG15. Due to the project’s low headroom requirements, and tight access through existing live building structures, separate stages of work with 2 of our piling rigs had to be utilised to accommodate the varying conditions.
Extension of the existing multi-storey Youth Hostel building.
Design and construction of 420mm and 319mm diameter perimeter Cased CFA Secant Pile wall to allow for excavation of a single level basement below ground water table. Limited working area, and pile tolerances to property boundaries and existing structures were critical in the project.
Additionally, 450mm diameter CFA Foundation piles were designed and installed to socket into rock below water table.
Supply and installation of dewatering services for the required duration through the basement construction in accordance with Byron Bay City Council stringent standards.
4 Archer Street, Bilinga
Design and construction of perimeter sheet piles for a single level basement, including a combination of cantilevered and internally braced sheet piles for a car-stacker over-excavation. Ausipile was involved in the installation of the sheet piles in medium dense to dense sands and both the design and installation of the internal steel bracing.
1-3 York St, Nundah
1-3 York Street, Nundah is an 8-level residential development with a single level basement.
The project involved the installation of 70 no. of 350mm diameter soldier piles at 700mm centres with a mix of both cantilevered and propped piles.
