Mini Piling & SFA

/Mini Piling & SFA

Mini piling rigs are convenient for areas with restricted access or limited headroom. Sectional flight augers are able to achieve impressive depths in spaces as little as 2.2m in height. Each section of auger is bored into the ground, and then another section is attached and secured with auger pins to drill the next section.

Technical Info

Diameter: 100mm – 450mm.

Depth: 15m – 20m.

Ground Condition: potential heave in unstable ground.

Benefits

Construct bore holes / underpin existing structures / inject grout or concrete.

Compact shape for small entrances such as doorways.

Strings of augers allow for greater achievable depths.

Low decibel readings for less noise and vibration.

Can operate in areas with low ceilings from 2.2m headroom.

Process

Depending on the ground condition and size of the structure, lengths of hollow stem augers are piled to design.

PILING
The lead auger is drilled into the ground, an auger plate is then inserted near the drill head in order to disconnect it from the auger and raise the drill head to add an intermediate section of auger. Auger pins lock both parts of auger together and the new section is pinned securely to the drive unit.

EXTRACTION
Due to the conical structure of the auger, excess spoil is forced up the length of the auger during drilling. Upon extraction clay / soil is withdrawn with the auger leaving a clear borehole. A wire frame may be used to reinforce the pile before grout or concrete is cast in-situ.
