Definitions

  • the present invention relates to a sheet pile for supporting sub-surface material when the sheet pile is driven in use into the ground.
  • vibratory hammers are used to impart vibrations to a sheet pile so as to reduce soil resistance and thereby cause insertion of the sheet pile into the ground.
  • the sheet pile must nevertheless be capable of withstanding the driving force imparted by the vibratory hammers, and of withstanding forces imparted by sub-surface material adjacent the sheet pile when the" sheet pile has been driven into the ground and subsurface material removed from one side of the sheet pile.
  • a disadvantage associated with this type of sheet pile is that weakening and/or tearing of the sheet pile can occur along the edges during or after the sheet pile has been driven into the ground, in particular adjacent transverse sides of the sheet pile.
  • the strength of the sheet pile for a given sheet pile thickness can be optimised.
  • the width of the flat portion of each crest and trough is selected so as to be sufficiently small to avoid buckling of the sheet pile at the respective crest or trough during use, though not too small such that strength advantages of generally flat crests and troughs is negated.
  • a sheet pile for supporting sub-surface material when the sheet pile has been driven in use into the ground, the sheet pile including a plurality of substantially flat sheet pile portions and a plurality of fold regions, each fold region being disposed at a junction between adjacent substantially flat sheet pile portions and having a substantially rounded cross sectional profile, the sheet pile having a transverse cross section of substantially corrugated configuration including a central trough of substantially flat configuration and first and second crests of substantially flat configuration adjacent the central trough, transverse dimensions of the central trough and the first and second crests being selected such that optimum strength is obtained.
  • a sheet pile for supporting sub-surface material when the sheet pile has been driven in use into the ground, the sheet pile including a plurality of substantially flat sheet pile portions and a plurality of fold regions, each fold region being disposed at a junction between adjacent substantially flat sheet pile portions and having a substantially rounded cross sectional profile, the sheet pile having a transverse cross section of substantially corrugated configuration including a central trough of substantially flat configuration and first and second crests of substantially flat configuration adjacent the central trough, transverse dimensions of the central trough and the first and second crests being sufficiently small so as to avoid buckling of the sheet pile at the respective crest or trough during use and being sufficiently large so that strength advantages of substantially flat crests and troughs are obtained.
  • the sheet pile includes a single fold region between each transverse side of the sheet pile and an adjacent substantially flat sheet pile portion extending between a crest and a trough.
  • two crests and three troughs are provided. In an alternative embodiment, three crests and four troughs are provided.
  • the transverse dimension of the central trough is substantially equal to the transverse dimension of each of the first and second crests.
  • a method of forming a sheet pile for supporting sub-surface material when the sheet pile has been driven in use into the ground including the steps of: forming a sheet of material so as to define a sheet pile having a transverse cross section of substantially corrugated configuration including a plurality of substantially flat sheet pile portions and a fold region at each junction between adjacent substantially flat sheet pile portions, each fold region having a substantially rounded cross sectional profile, the sheet pile including a central trough of substantially flat configuration and first and second crests of substantially flat configuration adjacent the central trough; and selecting transverse dimensions of the central trough and the first and second crests such that optimum strength is obtained.
  • the step of forming the sheet of material includes the sub-step of forming the sheet of material so as to define a single fold region between each transverse side of the sheet pile and an adjacent substantially flat sheet pile portion.
  • the step of forming the sheet of material includes the sub-step of forming the sheet of material so that the transverse dimension of the central trough is substantially equal to the transverse dimension of each of the first and second crests.
  • the method further includes the step of selecting a depth dimension of the sheet pile such that the depth is sufficiently small to avoid buckling during use but not so small that strength advantages of a corrugated configuration cross section are negated.

  • Figures 2a and 2b are diagrammatic perspective and end views respectively of a second prior art sheet pile, the second prior art sheet pile being associated with and connectable to the first prior art sheet pile shown in Figures la and lb;
  • Figures 3 a and 3b are diagrammatic perspective and end views respectively of a first sheet pile in accordance with the present invention.
  • Figures 4a and 4b are diagrammatic perspective and end views respectively of a second sheet pile in accordance with an embodiment of the present invention, the second sheet pile being associated with and connectable to the first sheet pile shown in Figures 3 a and 3b;
  • Figures 5 to 12 are diagrammatic perspective and end views of associated first and second sheet piles of alternative embodiments of the present invention.
  • first and second prior art sheet piles 10 and 12 are of generally corrugated transverse cross-section and are formed by folding along fold lines 26 to produce elongate edges.
  • corrugated piles By providing corrugated piles, the likelihood of buckling of the piles in use is reduced.
  • a corrugated profile facilitates the use of two sets of clamping jaws during a pile driving operation.
  • An embodiment of first and second sheet piles 28, 30 in accordance with the present invention is shown in Figures 3 and 4.
  • the first and second sheet piles 28, 30 include first flat portions 14 generally disposed in a first plane and second flat portions 16 generally disposed in a second plane parallel to the first plane.
  • the first and second flat portions 14, 16 are interconnected by further flat portions hereinafter referred to as first and second intermediate portions 18, 20, each of which defines an obtuse angle with an adjacent first flat portion 14 and an adjacent second flat portion 16.
  • Elongate sides of the first sheet pile 28 are provided with first and second end portions 22, 24.
  • Elongate sides of the second sheet pile 30 are provided with first end portions 22.
  • the first and second flat portions 14, 16 are approximately equal in width.
  • the first sheet pile 28 also includes connection means, hereinafter referred to as a clutch 27, for facilitating connection of the first sheet pile 28 to the second sheet pile 30.
  • connection means hereinafter referred to as a clutch 27, for facilitating connection of the first sheet pile 28 to the second sheet pile 30.
  • the first and second sheet piles 28, 30 are also provided with end fold regions 32 of generally rounded cross-sectional profile and intermediate fold regions 34 also of generally rounded cross-sectional profile.

Abstract

L'invention concerne une palplanche (28, 30) servant à retenir des matériaux situés en dessous de la surface du sol une fois qu'elle a été enfoncée dans le sol. La palplanche (28, 30) comprend une pluralité de zones sensiblement planes (14, 16, 18, 20) et une pluralité de zones de pli (34). Ces zones de pli (34) sont situées à la jointure entre les zones sensiblement planes adjacentes et présentent une section transversale sensiblement arrondie. La palplanche (28, 30) a une section transversale sensiblement ondulée formée par une rainure centrale sensiblement plane et par une première et une seconde nervure sensiblement planes situées de part et d'autre de la rainure centrale. Les dimensions transversales de la rainure centrale et de la première et de la seconde nervure sont définies de façon que la résistance soit maximale, c'est-à-dire, que la première et la seconde nervure sont suffisamment petites pour éviter le gauchissement de la palplanche (28, 30) au niveau de la rainure ou des nervures et suffisamment grandes pour fournir à la palplanche les avantages, en termes de rigidité, apportés par des rainures et des nervures sensiblement planes.
