Piling - Roger Bullivant
Roger Bullivant Ltd offers an impressive array of piling techniques that enable us to tailor our foundation systems to the needs of our clients. Our versatile range of products stem from the more traditional driven piling suite, comprising driven concrete piles, driven tubular steel and combination piles, to our vibrated or cast insitu piles such as our CFA or CHD piles. With the advent of our Continuous Helical Displacement pile, arisings have been virtually eliminated allowing significant savings to our client in muckaway costs and programme. With increased environmental awareness this piles is ideally suited to contaminated land or inner city projects where muckaway and treatment costs have been prohibitive to development.
With projects ranging in value from several thousand to a million pounds, we at Roger Bullivant Ltd are confident we can accommodate your piling needs and deliver the most cost-effective, value engineered solution to meet your construction programme needs.
PRE-CAST CONCRETE PILES
Application
This pile may be used for all types of structures and foundations, from housing, through other forms of domestic building, to commercial and industrial buildings and installations. The piles can also be used for all types of civil engineering 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 and very cost-effective in most ground conditions. This pile is environmentally attractive as no spoil or arisings are generated from pile installation.
In its standard form the pile is a compression pile with small tensile and bending resistance capability. The design is however, easily adapted to accommodate larger tension and bending forces. The standard segment lengths of 1.5m, 3m and 4m can be complemented as required by 6m segments and by tapered lead sections or enlarged lead sections, as required.
CONTINUOUS FLIGHT AUGER (CFA) PILES
Application
General all purpose application for new and refurbishment projects.
The piles are speedily installed and can cater for a variety of ground conditions. They are cost-effective and can accommodate large working loads, depending upon the ground conditions into which they are installed.
The standard size range may be complemented with intermediate sizes if required and pile lengths of up to 19m can be constructed.
Standard reinforcement details are used where appropriate which will comprise single centrally positioned reinforcing bars or reinforcement cages as required to suit horizontal or bending moment loadings. Special cages can be manufactured to suit specific loading situations.
TUBULAR STEEL PILES UNRESTRICTED ACCESS
Application
Whilst clearly being suitable for taking large axial loads, these piles are particularly suitable for accommodating significant horizontal loads and vertical tension loads, induced by large bending moments/horizontal reactions and uplift/heave reactions respectively.
These piles are also very suitable for driving in difficult or uncertain ground conditions up to 50m deep. Hard driving conditions and fill, obstructions or boulders can also be dealt with using this system.
These piles are ideal where embedment is required on a steeply sloping bedrock and supplemental rock-socketing by drilling through the end can be achieved in extreme slope conditions or where load capacity at rockhead needs to be increased.
CONTINUOUS HELICAL DISPLACEMENT (CHD) BORED DISPLACEMENT PILES
Application
This type of pile can be used for all foundation applications where bearing piles are required for either buildings or structures. The pile may also be used where there is a retaining requirement. The ability to form bored piles without producing any spoil makes this kind of pile particularly advantageous on contaminated sites. There is minimal vibration and noise.
In most ground conditions, this pile is an ideal alternative to CFA (continuous flight auger). Enhanced load carrying capacity may be achieved compared with CFA piles of similar dimensions, due to compaction of the soil during boring. In some ground conditions improvements of up to 30% have been demonstrated with a consequential shortening of the pile and reduction in cost.
