P I L E T Y P E RB Pre-cast concrete pile

A P P L I C AT I O NThis pile may be used for all types of structures andfoundations, from housing, through other forms of domesticbuilding, to commercial and industrial buildings andinstallations. The piles can also be used for all types of civilengineering applications from bridges to embankment support,power and transmission towers and rail-related structures.

The RB Pre-cast Concrete Piling System is quick to install andvery cost-effective in most ground conditions. This pile isenvironmentally attractive as no spoil or arisings are generatedfrom pile installation.

In its standard form the pile is a compression pile with smalltensile and bending resistance capability. The design ishowever, easily adapted to accommodate larger tension andbending forces. The standard segment lengths of 1.5m, 3mand 4m can be complemented as required by 6m segmentsand by tapered lead sections or enlarged lead sections, asrequired.

I N S TA L L AT I O NRB pre-cast concrete piles are usually top-driven usinghydraulic drop hammers, some of which are supersilenced andare part of the company’s fleet of remotely operated “Quiet”hammers. Hammer capacities range from 1T up to 10T for ourgeneral purpose low noise, low vibration hammers and can bemounted on a variety of tracked or wheeled rigs, dependingupon project location, type, access and headroom constraints.All rigs are designed and purpose-built in-house to meetspecific site access and transportation criteria.

The smaller sizes of RB pre-cast concrete pile may also bejacked into the ground using a totally vibrationless systemutilising RB in-house designed and built jack-down piling rigs.

Quality assurance procedures apply to pile manufacture anddelivery, unloading, storage and installation. RB pre-castconcrete piles are suitable for all open, unrestricted siteactivities, however the variety of segment lengths andexistence of specialist equipment makes them ideal forrestricted access and low headroom applications.

P I L E T Y P E RB tubular thick wall steel cased pile drivenin up to 6m lengths, with a spigot andsocket connection.

A P P L I C AT I O NWhilst clearly being suitable for taking large axial loads, thesepiles are particularly suitable for accommodating significanthorizontal loads and vertical tension loads, induced by largebending moments/horizontal reactions and uplift/heavereactions respectively.

These piles are also very suitable for driving in difficult oruncertain ground conditions up to 50m deep. Hard drivingconditions and fill, obstructions or boulders can also be dealtwith using this system.

These piles are ideal where embedment is required on asteeply sloping bedrock and supplemental rock-socketing bydrilling through the end can be achieved in extreme slopeconditions or where load capacity at rockhead needs to beincreased.

I N S TA L L AT I O NThese piles are top driven to ‘set’ or length using purpose-builtrigs with hydraulic hammers. The internal void cansubsequently be filled with concrete or grout if required andreinforcement incorporated for bonding into pile cap or groundbeams. Normally the piles are driven open ended so that asoil plug is rapidly formed. In exceptional circumstances theopen end can be closed using a welded end plate.

S I T E R E Q U I R E M E N T SThe site should be firm, dry, flat and level, and capable ofsustaining the load of the piling rigs which typically will weighup to 35T. Access roads must be suitable for normal deliveryvehicles.

P I L E T Y P E RB continuous helical displacement pile


A P P L I C AT I O NThis type of pile can be used for all foundation applicationswhere bearing piles are required for either buildings orstructures. The pile may also be used where there is aretaining requirement. The ability to form bored piles withoutproducing any spoil makes this kind of pile particularlyadvantageous on contaminated sites. There is minimalvibration and noise.

In most ground conditions, this pile is an ideal alternativeto CFA (continuous flight auger). Enhanced load carryingcapacity may be achieved compared with CFA piles of similardimensions, due to compaction of the soil during boring.In some ground conditions improvements of up to 30% havebeen demonstrated with a consequential shortening of thepile and reduction in cost.

I N S TA L L AT I O NThe piles are formed using a highly efficient multi-flight, bulletended shaft, driven by a high torque rotary head, enablingpenetration of the strata without bringing material to thesurface. Data is recorded using computerised instrumentation.

Nominal surface heaving may occur but compared with thearisings from CFA boring, the volume is negligible.

This is a bored pile which displaces the soil through which it isconstructed. It creates no appreciable arisings and therefore,there is minimal spoil to remove from site.

There are currently two standard sizes as shown below:

*Dependent on ground conditions.

NO SPOIL PRODUCEDREDUCED VIBRATIONcompared with traditional dynamiccompaction

TOTAL AREA TREATMENT

Once drilled to calculated or proven depth, concrete ispumped under pressure down the hollow shaft to the boringhead and out of the tip while the shaft is reverse rotated andwithdrawn from the bore. Reinforcement in the form of cage orsingle bar is introduced into the bore upon completion of theconcreting operation.

Reinforcement is left protruding from the pile as appropriatefor forming connections to following structural elements.Surface heave and waste concrete is cleared from theformation to complete pile construction.

Whilst the rig is relatively large it can be operated on bothopen, unrestricted access sites and in difficult, confined areas.Headroom of 22m is required for the standard rig but lowerheadroom options are available together with rigs forconstructing bored piles inside buildings.

T H E B E N E F I T S O F U S I N G T H E C H DS Y S T E M� The system creates no appreciable arisings therefore:

there is no double handling of spoil on site and no spoilheaps.

there is virtually no spoil to remove.

there are no associated adverse environmental effectsor costs.

� There is no vibration and minimal noise; thus piles can beconstructed closer to existing buildings and structuresthan with other systems.

� Pile integrity is enhanced as the displacement boringmethod reduces the potential for “necking”.

� Another environmental benefit is that better use is madeof the pile materials, thereby minimising the number oflorry movements to the site and saving natural materialsby reducing waste.

� Geotechnically, this type of pile performs better than asimilar CFA pile. Different ground conditions producevarying benefits, but the most useful is the potential toshorten the pile.

� This installation system is rapid and as a result providesbenefits to contract programming.

� Rapid installation also eliminates the need for on-sitestatic agitators, pumps and pump-lines. Concreting iscarried out using mobile concrete pumps.

A P P L I C AT I O NGeneral all purpose application for new andrefurbishment projects.

The piles are speedily installed and can caterfor a variety of ground conditions. They arecost-effective and can accommodate largeworking loads, depending upon the groundconditions into which they are installed.

The standard size range may be complementedwith intermediate sizes if required and pilelengths of up to 19m can be constructed.

Standard reinforcement details are used whereappropriate which will comprise single centrallypositioned reinforcing bars or reinforcementcages as required to suit horizontal or bendingmoment loadings.

Special cages can be manufactured to suitspecific loading situations.

I N S TA L L AT I O NRB CFA piles are formed using hollow stemauger boring techniques, which will producearisings from the bores in most UK groundconditions. Having produced a bore tocalculated depth through known strata,concrete is pumped into the bore underpressure and continues to be pumped as theauger flight is lifted.

Concrete simultaneously fills the void left by theauger extraction. The reinforcement is installedin the bore after the pile has been concreted.

The company operates a fleet of bored pilingrigs which have the capability of installingcomputer-controlled continuous flight auger(CFA) piles and sectional flight auger (SFA)piles. These are suited to all types of conditionsfrom open, unrestricted access sites to veryconfined, low-headroom situations.
