RASA Pipe Jacking Machine


Pipe jacking, also known as microtunneling, is a trenchless method of installing pipelines underneath highways, buildings, rivers and more. Due to less surface works required, it is highly efficient and greatly reduces any adverse effect on the surrounding environment.

A pipe jacking system typically consists of:

• Shield Machine
• Control Room
• Gyro Navigation System
• Hydraulic Jacking System
• Warman Pump
• Lubrication System
• Slurry Treatment System
• Electrical Generator

The DH UNICORN, one of RASA’s most popular pipe jacking machine series, is capable of handling pipe size (internal diameter) of 250mm to 3000mm, and excavating through a variety of ground conditions including boulder, soft rock, medium hard rock, and hard rock layers. By changing its customisable cutter disk, the machine can also be used in ordinary soil, hard soil, and cobble gravel layers.

Advantages in a nutshell:


• Powerful Crushers

The machine adopts a two-stage crushing mechanism. Primary crushing is performed by roller bits installed on the cutter disk that rotates at a large torque, followed by secondary crushing performed by a robust cone crusher located behind the cutter face.

• Customised to Precision

With a variety of cutter disks available, the machine can be customised according to ground conditions for the best excavation performance.

• Economical

The ease of constructing the machine and its remote-control capabilities will keep operational costs to a minimum.
