    masterum
    This document provides information on driven steel piles as a piling technique. It describes how steel piles can be driven harder than concrete piles to penetrate obstructions. Steel piles deliver improved shear and bending capacity. They also produce significantly less vibration during driving compared to alternative pile types. The document discusses the strengths of steel piles including reduced vibration, no spoil generation, ability to be driven hard through obstructions, and high load capacity. It provides technical details on pile sizes and load capacities.

    TECHNIQUE SHEET

    Driven steel piles can deal more readily with obstructions than precast concrete piles, as
    they are more robust and can be driven harder. Furthermore, they deliver an improved
    shear/bending capacity and driving using their “cutting” edge can provide significantly
    reduced vibration over alternative driven piles.
    BASIC TECHNIQUE CAD IMAGE OF DRIVEN STEEL PILING RIG
    BBGE offer driven steel tube piles and steel H-Piles. The
    open-ended steel tubes are typically former oil casings
    and either 177mm or 244mm in diameter and up to
    13mm in section (sections up to 768mm diameter can
    be driven). The smaller sized tubes are up to 15m in
    length and are ‘threaded’ and ‘collared’ allowing piles to
    be extended to whatever depth is required, depending
    on ground conditions and loads required. However they
    are normally driven with a simple interference fit.
    Driven piles can also be raked up to 1:3 depending on
    hammer weight and pile size. If tension loads are
    required the tubes can be welded. It is usually
    unnecessary to fill the tube with concrete, after driving.

    STRENGTHS
     Reduced vibration levels compared to precast piles
     No spoil generated on site
     Ready for immediate follow-on construction
     Robust piles can be driven hard to penetrate
    obstructions and socket into weak rock
     High shear and bearing capacity
     Low carbon footprint as second-hand steel tubes
    used, so no ‘embodied’ carbon is produced PM20 DRIVEN PILING RIG
