Definitions

  • the invention relates to pile driving, and more particularly, but not exclusively, to underwater pile driving, e.g. for stabbing piles directly into the seabed.
  • DESCRIPTION OF THE BACKGROUND ART It is known to provide a guide for aligning a pile with the surface of a substrate into which the pile is to be driven and to provide stability for a piling hammer. Particularly when piling underwater there is the problem that after the pile has been introduced into the seabed or the like, the guide must be removed to allow the pile to be driven into its final position. This guide removal is time consuming and thus expensive. Accordingly, the present applicant proposed in International patent publication W099/11872 a pile guide which allows pile driving to continue from start to finish without any need to interrupt driving to remove the guide .
  • the pile driving apparatus described in 099/11872 is supported on a base frame, a plan view of which is reproduced in Figure 1.
  • the base frame 10 has a substantially rectangular footprint (made up of a welded framework of girders and mudmats) with a centrally-placed aperture (12) through which a pile (14) is guided.
  • the base frame 10 thus surrounds the pile (14) .
  • the base frame is formed with an aperture or slot (16) extending through the frame from its exterior to the central aperture (12) and through which a tether or rigging (18) fixed to the pile (14) can be passed.
  • the present applicant has appreciated certain problems associated with transporting a pile guide of the kind shown in W099/11872.
  • the rectangular footprint of the base frame may have an area exceeding 100m 2 , effectively ruling out all forms of transport other than by sea.
  • the present applicant has sought to obviate or at least alleviate such problems.
  • a pile guide for supporting a pile as it is driven into a substrate, comprising a base frame and a pile guide member mounted on the base frame characterised in that the base frame comprises a rigid member, preferably substantially U-shaped and at least one ground- engaging panel releasably coupled to the rigid member.
  • the releasable coupling between the U-shaped member and the at least one ground engaging panel enables the pile guide to be transported in more than one piece to the site where it will be used.
  • This fact overcomes dependence on transport by sea alone, since each piece may be moved, for example, by road, albeit with a police escort if required.
  • Such improved transportability is important since it is in the very nature of pile driving that the pile guide must be moved from site to site if it is to be reused.
  • the substantially U-shaped rigid member may support the pile guide member.
  • the rigid member has a central aperture through which a pile guided by the pile guide member may be driven.
  • Being substantially U-shaped there is a channel, communicating with the central aperture, through which a tether or rigging fixed to a pile may pass in order to disengage the pile guide from the pile once driven into the substrate.
  • the present applicant has appreciated that the U-shaped rigid member is the backbone of the pile guide, having to withstand the stresses of supporting the pile guide member even during pile driving.
  • the pile guide member may be of conventional form (e.g. an immobile channel adapted to receive slidingly a pile to be driven into the substrate) or of improved form (e.g. of two part and pivotable construction, each part being adapted to pivot away from the pile once partially driven into the seabed, see 099/11872) .
  • the at least one ground-engaging panel, or mudmat may extend laterally of the substantially U-shaped rigid member.
  • the at least one ground-engaging panel may be releasably coupled to the rigid member by a plurality of bolts .
  • the base frame may include a pair of ground-engaging panels, releasably coupled one per opposing side of the substantially U-shaped rigid member. Each ground- engaging panel may extend laterally of the respective side of the
  • the at least one substrate-engaging panel or the substantially U-shaped rigid member may comprise receptors for engagement by fork means of a fork-lift truck.
  • the receptors may comprise a pair of flanges which project laterally such that their undersides are contactable by the fork means of a fork-lift truck.
  • Each flange may form part of a channel, either of open- or closed-box construction.
  • the pile guide may further comprise means for attaching lifting lines (e.g. ropes or cables) to the base frame.
  • the attaching means may be selected from the group consisting of hooks, rings and apertures.
  • the substantially U-shaped rigid member and the at least one substrate-engaging panel may include location means for secure stacking of one on top of the other.
  • the location means may comprise complementary profiles which enable one to nest against the other.
  • a pile guide for supporting a finned pile as it is driven into a substrate, comprising a base frame and a guide member mounted on the base frame, characterised in that the guide member comprises a pair of upright guide channels for receiving and guiding a pair of stabilising fins associated with a finned pile during pile driving .
  • finned piles of a smaller diameter than conventional piles may be used.
  • the use of more lightweight finned piles enables a consequential reduction in the build specification of the corresponding pile guide; leading to cost savings in terms of both materials and transportation considerations.
  • a third and potentially more significant advantage arises from the flexibility of using a pile guide which guides fins associated with a pile, rather than the main body of the pile. Provided the fins achieve a given "wing span" , variable diameter piles may be supported by the same pile guide. This in turn has a knock-on benefit of speeding up pile driving a set of finned piles of different sizes, since the same guide may be used for each.
  • the pair of upright guide channels may be positioned opposite each other, with channel openings facing each other.
  • the guide channels are configured to receive a finned pile having a pair of diametrically opposed stabilising fins extending in an axial direction along the curved periphery of the pile.
  • the upright guide channels may be supported by inclined struts extending from an outer periphery of the base frame .
  • apparatus for driving a pile into a substrate comprising a pile follower for transmitting impact from a pile driver to a pile being driven into a substrate, wherein the pile follower has a pair of fins for engaging corresponding guide channels of a pile guide.
  • a pile may be part-driven into a substrate (e.g. seabed) with the aid of a pile guide.
  • a follower can be fitted to the exposed end of the pile.
  • the follower In order to transmit pile hammer impacts squarely to the pile in such a way as to drive the pile vertically, the follower has traditionally been machined to very tight tolerances which is expensive with such a large object.
  • the follower can be guided in the same way as a finned pile. In this way, the need for accurate machinery is substantially reduced.
  • the pair of fins may extend in a common plane to engage diametrically opposed guide channels of the pile guide.
  • the pile follower may have an end profile comprising a driving face and an alignment member projecting axially beyond the driving face.
  • the alignment member aids registration of the driving face with the exposed end of the pile by providing a positive locating action therewith.
  • the alignment member may be configured to engage the radially inner periphery of a tubular pile.
  • the alignment member may comprise a plurality of plates arranged around the radially inner or outer periphery of the pile follower.
  • the apparatus may further comprise a pile guide in accordance with earlier aspects and embodiments of the present invention.

  • the pile guide member (27) comprises a pair of upright guide channels (30) mounted on the rigid member
  • the pile guide (20) may be dismantled to improve ease of transportation, and, in particular, the base frame (22) constituents may be decoupled into three more manageable pieces, namely two mudmats (28) and the rigid member (26) .
  • FIG 4 illustrates the construction of the base frame (22) in more detail.
  • the generally U-shaped rigid member (26) forms the backbone of the structure and is also fundamental to the operation of the pile guide (20) .
  • the rigid member not only provides the points of anchorage for the pile guiding member (24) and mudmats (28) , but also defines a central aperture (40) through which a pile is driven into the substrate. Thereafter, the base frame (22) may be disengaged from around the pile by moving the base frame (22) to pass the pile through channel or peripheral opening (42) ; the peripheral opening having a span which exceeds the diameter of the pile.
  • the mudmats are examples of the pile through channel or peripheral opening (42) ; the peripheral opening having a span which exceeds the diameter of the pile.
  • the base frame (22) may have a footprint covering something in excess of 100m 2 .

  • the sides of the rigid member (26) and mudmats (28) are provided with receptors (50) for receiving the forks of fork-lift trucks.
  • the receptors (50) comprise a pair of flanges (52) forming an open channel into which the prongs of a fork-lift may be inserted. The uppermost flange in each pair then bears the weight of the component during lifting.
  • Padeyes (60) are also provided at the corners of the rigid member (26) for attaching lifting lines (e.g. cables) and thereby lifting the base frame (22) .
  • the pile guide member (24) illustrated in Figures 2 and 3 is just one of several different designs which could be used in combination with the base frame (22) .

  • the pair of upright guide channels (30) are positioned opposite each other with channel openings facing each other. In this way, the channels receive and guide the stabilising fins during pile driving.
  • the pile guide (20) may be lifted over the protuberant part of the pile to disengage the stabilising fins from the pile guide member.
