Equipment Technology, MethodologyRotary Drilling with Kelly - Equipment

Piling

Continuos Flight Auger System

CONSTRUCTION METHOD MAIN APPLICATIONS FEATURES

Driven Piles (generally) cohesive soils and loose sands

high pile quality can be guaranteedbecause of pre-cast concrete elements orsteel piles (Larsen, etc.)

Improvement of soil during installation dueto displacement of soil

low settlements

very noisy work

Grab construction, fully cased Soil such as sand and gravels with highdemands on casing technology

Where it is economically viable to usechisels to break up bedrock and boulders

Minimum distance to existing buildings isrequired

Pile diameter generally ranging from 620to 2000 mm

Depths generally up to 50 m

Rotary drilling with Kelly, fully cased All types of soil

Where site conditions are restricted

Vibration free drilling

High output by casings installed by rotarydrive

casings depth down to 20 m

standard diameter 620 to 1500 mm

Drilling close to existing buildings

Rotary drilling with Kelly and Oscillator, fullycased

All types of soil

Where site conditions are restricted


casings depth down to 50 m

diameter less than 2000 mm

Drilling close to existing buildings

Rotary drilling with Kelly, borehole supported byhydrostatic pressure

In all types of soil

Large diameter piles

Deep piles


No casing required

Starter casing used for top section only

Wall of borehole supported by bentonite orpolymer slurry

Borehole diameter generally 300 to 3000mm

Depth generally up to 40 m, but greaterdepths possible

Vertical piles only

Piles

Rotary Drilling with Kelly

Rotary Drilling using continuos flight auger

Installation of the temporary casing

with the rotary driveof the drill rig

Excavation of the soil with the drill bucket, stabilisation of the

borehole with slurry( bentonite or polymere

)

Cleaning the slurrywith the desander

Installation of the reinforcement cage

by the auxiliarywinch of the drill rig

Pouring the con-crete into the bore-hole through the

tremie pipe. Remove slurry by pumping back to the tank

Remove temporary casing with the

rotary drive of the drill rig

Uncased Drilling Method- Hole supported by hydrostatic pressure

Fully Cased Drilling with Oscillator

Drill and push the casings into the ground

with the rotary drive (and attached oscillator)

Drill with the rotary tools: bucket, auger or core barrel. Stabilised the

wall of the bore with the casing

Install reinforcement cage with the auxiliary

winch of the drill rig into the bore stabilised by the

casings

Pour concrete through the tremie pipe into the

cased borehole

Extract the casing with the rotary drive during concreting (with the os-

cillator)

Oscillator attached to the drill rig :• hydraulic power supply from the base machine of

the rig• the oscillator is locked to the undercarriage of the

rig. During installation of the casing the total weight of the rig acts as a reaction mass which improves

the pushing force.

Fully Cased Drilling with Oscillator

Rotary drilling using Flight Auger - Equipment

Drilling with Continuous Flight Auger (CFA)

Beton

Drilling with CFA auger. Soil is continuously transported from the tip of the auger upwards by the flights. The

borehole is stabilised by the auger filled with soil.

After reaching the final depth the auger is withdrawn and concrete is pumped through the hollow stem with the concrete pump.

Remove the excavated soil with a hydrau-lic excavator. Push or vibrate the reinforce-

ment cage into the freshly poured pile.

Anchors

Grouting

Ductile Driven Pile System

Pipe joint, comprising conicalsocket and spigot

Head plate fixed to the pile head

The driving shoe ensures that cobbles and other small obstructions are displaced or crushed when necessary during driving


Skin friction pile:Cement grout is pumped through the ductile pipe during pile driving and injected continuously

through the driving shoe.Excavated grouted section of a

skin friction pile: BAUER ductile pile foundation immediately

adjacent to an existing building


Advantages over other Foundation Techniques

· Short installation period· Simple site set-up

· Minimal requirements with regard to working platform and

access· No additional site traffic due to

suppliers· No drill spoil

· Minimal wastage due to adaptability of ductile pipes

· No work required on pile head, piles are immediately cut back to their exact cut-off level with

a disc cutter· Very low wear and tear on

equipment

Ductile piles being installed in the Hotel Summit Golf & Resort in Panamá
