Turbo Jet

The TURBOJET system consists of the injection of predetermined cement grout quantities into the soil whilst utilising contemporary mixing techniques.

Diameters range from 600mm to 1200mm.
Depth to 20m.

Applications

The TURBOJET system consists of the injection of predetermined cement grout quantities into the soil whilst utilising contemporary mixing techniques. The drilling and rotation speed of the tool used for the TURBOJET is pre-set according to the soil characteristics, the grout rheology, the injection pressure and the work scope itself (either Consolidation or installation of a cut-off wall).

The cement grout, injected at high pressure and speed, breaks up the soil strata and the ground is thus cut by the high pressure jets mixed by means of blades. The resulting finish is more defined than that of standard jet-grout columns, in fact perfectly formed soil-grout column’s are formed using the TURBOJET system.

The whole system is monitored via instrumentation that is positioned within the cab of the rig so that the rig operator is constantly being supplied with real time feedback, which assist in minimising grout ‘blow back’ and wastage.

Advantages

  • Can be installed in nearly all soil types
  • Very quick and precise construction
  • Designable strength and permeability
  • No harmful vibrations
  • More efficient than alternate methods
  • Minimal spoil arising
  • Less grout wastage then other ground improvement/soil mixing techniques

  • Section of DSM

Project Outline

Yagan Square is part of the Perth City Link Project were Avopiling WA Pty Ltd was previously involved. Because of its Aboriginal significance Yagan Square is named  after "Yagan" a Noongar Warrior aboriginal leader.

Scope of Works

Working closely with Doric Contructions, Public Transport Authority and Metro Redevelopment Authority, Avopiling WA have been awarded for the design and construction of 13no x 880mmØ segmental cased bored piers to 37.00 m deep, 6no x 900mmØ permanently cased bored pier to 35.00 meters deep, 20no x 750mmØ CFA piles to 14 meters deep and 242no x 600mmØ deep soil mixing columns DSM using Turbo Jet System.
