Definitions

  • the invention relates to a method of making sheet piling and to an asymmetric-Z-section sheet pile for use in the method.
  • planking, landing stages, wharves and similar bank provisions along waterways have been composed of separate driven hot-rolled steel sheet piles, which are joined to each other by means of interlocking hooks extending along their edges (forming the so-called lock).
  • a retaining wall For a retaining wall to be formed, such piles are driven or vibrated into the ground successively or in groups, with adjoining sheet piles interlocking through the hooks extending throughout the length of the free edges.
  • the sectional profile of the finished retaining wall is determined by the profile of the piles that are used and by the relative position of the successive piles, which depends on whether the piles are all driven in in the same position or whether each successive pile is rotated through 180° about its longitudinal axis relative to the preceding pile.
  • a retaining wall has a crenellated cross-section, the C-shaped hollow sides being referred to as channels.
  • An anchor is a rod with a widened end, extending through a sheet pile into the ground behind the pile.
  • the rod is connected at the front of the pile by means of an anchor seat, which is welded to the pile.
  • grout anchors in which the anchor rod is guided through a tube and its free end is arranged in a ball of mortar (grout).
  • Z-shaped pile sections i.e. piles of a sectional form which is composed of two parallel end flanges which are joined by an inclining intermediate portion, are more eligible than U-shaped or ⁇ -shaped pile sections as regards cost price.
  • U-section sheet piles have a trapezoidal section formed by an intermediate portion with two slightly diverging flanges whose free ends terminate directly in the locking hooks.
  • each successive pile has been rotated through 180° about its longitudinal axis relative to the preceding pile.
  • the locks in the retaining wall are in the "neutral line" and the theoretic moment of resistance is thereby reduced.
  • ⁇ -shaped pile sections i.e. piles with a sectional form consisting of an intermediate portion, two diverging flanges with two end portions which extend parallel to the intermediate portion and terminate in locking hooks, have so little stiffness of their own in the case of small wall thickness, that they are hard to manipulate in the case of greater widths. It is therefore customary to compose ⁇ -shaped pile sections from Z-section piles by joining them in pairs and interconnecting them by spot welding, while each successive pile is rotated through 180° about its longitudinal axis relative to the preceding one. By starting thus from Z-sections, ⁇ -sheet piling of great widths of 130 cm can be obtained without the disadvantage of poor rigidity inherent to ⁇ -section piles.
  • each channel contains enough space on the side of the lock extending therethrough, for an anchor seat to be mounted directly against the channel bottom. It only remains necessary that elliptical holes are burnt in the sheet piles in question for passing therethrough the anchor rod and a grout injection tube. This, too, may be done in a simpler manner than in sheet piling obtained in the conventional manner wherein the ⁇ -section sheet piles are made from symmetrically formed Z-piles because it is not necessary to burn through the lock extending in the middle of the channel.
  • the invention also relates to sheet piles having an asymmetrical Z-section for use in the method described above, which piles consist of a Z-shaped pile section, i.e. a pile formed from steel by hot rolling of cold formation, having a sectional form composed of two parallel end flanges connected by an inclined intermediate portion, the end flanges at their free ends being provided with a hook, wherein, according to the invention, the inclined intermediate portion is arranged off the centre of the pile, so that in a ⁇ -section pile composed of two of such Z-section piles, wherein one pile has been rotated through 180° about its longitudinal axis relative to the other pile, for the purpose of positioning an anchor plate, the lock connecting the two Z-section piles, is displaced laterally relative to the axis of the channel bottom.
  • a Z-shaped pile section i.e. a pile formed from steel by hot rolling of cold formation
  • the inclined intermediate portion is arranged off the centre of the pile, so that in a ⁇ -section pile composed of two of
  • a retaining wall is built up from piles 1 provided at the side edges with hooks 2,3 which interlock in the manner indicated to form a lock together for laterally coupling together the sheet piles.
  • Each sheet pile 1 in principle comprises an intermediate portion 4 and two flanges 5 and 6, adjoining thereto on opposite sides.
  • the hooks are provided directly at the end edges of the flanges 5 and 6.
  • adjoining to flanges 5 and 6 are end portions 7 and 8 formed with hooks 2 and 3.
  • Fig. 1 illustrates the problem that is the basis for the invention.
  • the base plate 10 of the anchor seat 11 can be welded against a flat part (the channel bottom 12) of a sheet pile. It is impossible for this plate 10 to be seated against the bottom of the channel 12 of the corresponding sheet piles, formed by the two flanges 6, because the lock 2/3 projects from the middle of the bottom 6+6.
  • the lock 2/3 In order to provide a flat support surface, either the lock 2/3 must be burnt away locally or the space on opposite sides of the lock must be filled up by means of filler plates 13, which is cumbersome and expensive.
  • the Z-section piles By forming, in accordance with the invention, as shown in Fig. 4, the Z-section piles asymmetrically, with the inclined intermediate portion off the centre of the pile 1, i.e. the flanges 5 and 6 are of different lengths, the lock 2/3 will be located laterally of the axis H-H and, on the side of the lock there will be enough space on the channel bottom 12 for an anchor seat 11.
  • Figs. 5 and 6 respectively, show a front view and a top plan view of the anchorage of a retaining wall which is built up from asymmmetrical piles 1 according to the invention and also show the conventional purlin 13, i.e. the transverse bracing.
  • Fig. 6 further shows a grout ball 14.
  • Fig. 7 shows in more detail the connection of the anchor seat 11 to the bottom of a pile channel 12 and concentric tubes 15 through which extends the anchor rod 9.
