Deep Stabilization Machines

By: Canadian Pile Driving Equipment  09-12-2011

Junttan deep stabilisation machines are used for consolidating soft ground. Columns, groups of columns, or walls are formed at the desired depth by mixing in-situ material with one or several binding agents and fillers. Lime, fly ash, gypsum and cement can all be used as binding agents, their selection depending on the soil type and application method.

The objective is always to produce a highly stable ground mass from the previously unstable material. In the Junttan product range there are three different types of deep stabilization machines in order to provide customers with the best possible machine for their work sites.

Junttan DS 18 is the newest member of the deep stabilization machines in the Junttan product range. It has been designed for dry mixing applications where stabilized column lengths are long (up to 25 meters).

The dry mixture method requires injection of the binding agent at low pressure into the soil followed by mixing to form the stabilized column. The deep stabilization method is used for consolidating soft ground. Columns, groups of columns, or walls are formed at the desired depth by mixing in-situ material with one or several binding agents and fillers. Lime, fly ash, gypsum and cement are all used as binding agents, their selection depending on the soil type and application method. The objective is always to produce a highly stable ground mass from the previously unstable material.

  • Compact to transport, despite its large capacity. All necessary equipment, including a drilling tube of up to 18 meters, can be transported as a single package.
  • Self-erecting leader and many advanced technical features ensure that the rig is ready to work in just a few minutes.
  • New leader support system guarantees that the rig has a long reach.
  • New generation measuring system enables the rig to produce homogeneous, high-quality columns.
  • Vertical movement of the rotary head is effected by chain traction, which makes the operation of the rotary head fast and precise.

Pile Driving Rigs

Junttan piling driving rigs can be transported without special arrangements in one piece, thanks to their small transport dimensions, and without having to remove the hammer. Product development has been enhanced by close cooperation with contractors and users, and many design details are a result of this practical experience.
