Definitions

  • the invention relates to a sheet pile assembly for a sheet pile wall. Furthermore, the invention relates to a sheet pile wall and a use of a sheet pile assembly and/or a sheet pile wall.
  • Sheet piles and sheet pile walls made of sheet piles are generally known from the state of the art, for example from DE 20 2016 101 909 U1.
  • Sheet pile assemblies made up of differently shaped sheet piles are known, for example, from GB 340,853 A and WO 99/11869 A1. These known sheet pile assemblies utilize two different types of sheet piles, which are arranged alternately next to each other and connected to each other, thus forming a sheet pile wall section.
  • Sheet piling is typically exposed to high mechanical loads throughout its service life.
  • sheet piling is often exposed to high bending and torsional loads.
  • high bending and torsional stiffness in particular a sufficiently high bending section modulus and a sufficiently high torsional section modulus, are required.
  • High stiffness can be achieved, for example, by using a large material thickness.
  • excessive material thickness is disadvantageous because the material requirement and the masses are then correspondingly large, which increases costs and makes the transport and handling of the sheet pile wall elements more complex.
  • the object of the invention is to provide a sheet pile assembly that allows adaptation to the on-site conditions and can withstand particularly high mechanical loads, if necessary, and that also has a lower weight while maintaining essentially the same mechanical properties.
  • a sheet pile arrangement having the features of claim 1.
  • a sheet pile arrangement for a sheet pile wall comprising a first outer sheet pile, which is preferably designed as a U-sheet pile, wherein the first outer sheet pile has a longitudinal extent running parallel to the driving direction, a second outer sheet pile, which is preferably designed as a U-sheet pile, wherein the second outer sheet pile has a longitudinal extent running parallel to the driving direction, a central sheet pile, which is preferably designed as a Z-sheet pile, wherein the central sheet pile has a longitudinal extent running parallel to a driving direction, wherein the central sheet pile is arranged between the first outer sheet pile and the second outer sheet pile.
  • the longitudinal extent of the central sheet pile deviates from the longitudinal extent of the first outer sheet pile and from the longitudinal extent of the second outer sheet pile.
  • a sheet pile arrangement which comprises three sheet piles, namely a first outer sheet pile, a second outer sheet pile and a central sheet pile arranged between these sheet piles, wherein the central sheet pile has a length which deviates from the length of the first outer sheet pile and from the length of the second outer sheet pile.
  • One advantage of such a sheet pile arrangement is that, when the central sheet pile is made shorter, there is essentially no deterioration in the mechanical properties. In particular, the stiffness of the sheet pile arrangement and thus also of the sheet pile wall remains essentially unchanged. Furthermore, less material is required for the sheet pile wall because the central sheet pile or the outer sheet piles are made shorter. This allows the material requirement for the sheet pile arrangement to be reduced in a particularly advantageous manner.
  • a further advantage is the reduced weight of the sheet pile assembly. Among other things, this makes it easier to transport the sheet piles for the sheet pile assembly to the installation site.
  • this type of sheet pile arrangement can be driven into the ground with less effort, since not all of the sheet piles need to be driven into the ground to the maximum depth of the sheet pile wall to be created.
  • This can also be particularly advantageous, for example, if a harder soil layer or an obstruction is present in a particular area. This simplifies the installation of a sheet pile wall, allowing it to be constructed more quickly and therefore at a lower cost.
  • a driving direction is understood in particular to be the direction in which a sheet pile wall is driven into the subsoil, and thus also the components extending along a sheet pile wall, in particular the sheet piles, are driven into the subsoil.
  • Driving into the subsoil is carried out in particular by driving the sheet pile wall into the ground.
  • the driving direction is perpendicular to the ground surface.
  • the driving direction is therefore usually vertical when installed.
  • driving directions that run parallel to the horizontal, for example when sheet piles or sheet piles for sheet pile walls are driven into mountains or hills, for example to support a tunnel.
  • Driving directions that have a horizontal and a vertical component are also possible, for example if the sheet pile wall is to be driven at an angle to the ground surface.
  • the driving direction corresponds in particular to the longitudinal direction of the sheet pile wall.
  • a longitudinal extension of a sheet pile is understood to mean the extension in the driving direction or parallel to the driving direction.
  • a sheet pile wall extension direction is understood to mean, in particular, a direction in which the sheet pile wall or a section of the sheet pile wall extends transversely to the longitudinal extension.
  • the sheet pile wall extension direction thus extends orthogonally to the driving direction.
  • the cross-section of the sheet piles of the sheet pile assembly and the cross-section of any connecting elements of the sheet pile assembly are each substantially constant along the longitudinal extent.
  • all elements of the sheet pile assembly have a cross-section that is substantially constant along the longitudinal extent.
  • the sheet piles can be hot-rolled or cold-rolled. Hot-rolled sheet piles are preferred.
  • a U-sheet pile is understood to mean, in particular, a sheet pile which has a substantially U-shaped cross-section.
  • a U-sheet pile has a straight central section and two further sections extending from the central section, namely the first and second sections of the first outer sheet pile and the second outer sheet pile, which can also be referred to as flanges.
  • the first section preferably extends substantially straight and is preferably oriented at an angle of more than 90° and less than 160° to the central section.
  • the second section preferably extends substantially straight and is preferably oriented at an angle of more than 90° and less than 160° to the central section.
  • the open side of a U-sheet pile is the side on which the U formed by the U-sheet pile is open.
  • a Z-sheet pile is understood to mean, in particular, a sheet pile which has a cross-section with a shape similar to the letter Z.
  • the Z-sheet pile has two straight sections, which can also be referred to as flanges and which are aligned parallel to each other, namely the first section and the second section of the central sheet pile, and a middle section running obliquely to the first and second sections, which is preferably also straight.
  • the sheet piles of the sheet pile assembly i.e., the first outer sheet pile, the second outer sheet pile, and the central sheet pile, as well as any connecting elements provided, each comprise or consist of steel.
  • all structural elements of the sheet pile assembly comprise or consist of steel.
  • the sheet pile arrangement can in particular form a partial section of a sheet pile wall.
  • the sheet pile arrangement preferably comprises exactly three sheet piles, namely the first outer sheet pile, the second outer sheet pile, and the central sheet pile.
  • the sheet pile arrangement preferably does not comprise any further sheet piles.
  • the first outer sheet pile and the second outer sheet pile are preferably designed as U-sheet piles
  • the central sheet pile is preferably designed as a Z-sheet pile.
  • Such sheet pile arrangements comprising precisely these three sheet piles can be arranged next to one another and connected to one another in such a way that each U-sheet pile is arranged adjacent to a U-sheet pile and a Z-sheet pile, and each Z-sheet pile is arranged adjacent to two U-sheet piles.
  • Such an arrangement makes it possible to achieve particularly advantageous mechanical properties, in particular high rigidity.
  • U-sheet piles are generally easier to manufacture and less expensive, so that the sheet pile arrangement as a whole is relatively easy to manufacture and relatively inexpensive to implement.
  • the central sheet pile is connected to the first outer sheet pile and to the second outer sheet pile.
  • the central sheet pile can be connected to the first outer sheet pile either directly or by means of a connecting element.
  • the central sheet pile can be connected to the second outer sheet pile either directly or by means of a connecting element.
  • the sheet pile arrangement comprises exactly three, i.e. no more and no fewer than three, sheet piles.

  • the longitudinal extension of the central sheet pile preferably deviates by no more than 50% from the longitudinal extension of the first outer sheet pile.
  • the longitudinal extent of the central sheet pile deviates from the longitudinal extent of the second outer sheet pile by at least 5%, preferably at least 10%, particularly preferably at least 15%, in particular at least 20%, from the longitudinal extent of the second outer sheet pile, and is preferably shorter than the longitudinal extent of the second outer sheet pile.
  • the longitudinal extension of the central sheet pile preferably deviates by no more than 50% from the longitudinal extension of the second outer sheet pile.
  • a surprising advantage is that with a length of the central sheet pile that is up to 20% shorter than that of the first outer sheet pile and the second outer sheet pile, essentially the same mechanical properties can be achieved for the sheet pile driven into the soil as in the normal case where all sheet piles are of the same length.
  • the longitudinal extent of the central sheet pile is shorter or longer than the longitudinal extent of the first outer sheet pile and/or wherein the longitudinal extent of the central sheet pile is shorter or longer than the longitudinal extent of the second outer sheet pile.
  • first outer sheet pile and the longitudinal extent of the second outer sheet pile are substantially identical. Accordingly, the first outer sheet pile and the second outer sheet pile are preferably of the same length, but with a length that differs from the length of the central sheet pile.
