Description

[0001] 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.

[0002] Sheet piles and sheet pile walls made of sheet piles are generally known from the prior art, for example, from DE 20 2016 101 909 U1. Sheet pile assemblies made of differently designed sheet piles are known, for example, from GB 340,853 A and WO 99 / 11869 A1. These known sheet pile assemblies use 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.

[0003] Sheet pile walls are typically exposed to high mechanical loads throughout their service life. In particular, sheet pile walls are often subjected to high bending and torsional loads. To withstand these loads, high bending and torsional stiffness, particularly a sufficiently high bending section modulus and a sufficiently high torsional section modulus, are required. High stiffness can be achieved, for example, through a large material thickness. However, excessive material thickness is disadvantageous, as the material requirements and mass are then correspondingly large, increasing costs and making the transport and handling of the sheet pile elements more complex.

[0004] In general, a large amount of steel is typically used for the installation of sheet piling. This high material consumption results in particularly high costs for the installation of sheet piling.

[0005] The invention is therefore based on the object of providing an improved solution that addresses the aforementioned problems. In particular, 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.

[0006] According to a first aspect, the object is achieved by a sheet pile arrangement having the features of claim 1. According to this, a sheet pile arrangement for a sheet pile wall is provided, the sheet pile arrangement 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.

[0007] According to the invention, the longitudinal extension of the central sheet pile deviates from the longitudinal extension of the first outer sheet pile and from the longitudinal extension of the second outer sheet pile.

[0008] A sheet pile arrangement is therefore proposed 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.

[0009] 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.

[0010] A further advantage is that the weight of the sheet pile assembly is reduced. Among other things, this makes it easier to transport the sheet piles for the sheet pile assembly to the installation site.

[0011] Another advantage is that such a 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 in the ground is present in a particular area. This simplifies the erection of a sheet pile wall, allowing the construction of a sheet pile wall to be completed more quickly and thus at a lower cost.

[0012] 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 ramming the sheet pile wall into the ground. In the majority of cases, the driving direction is perpendicular to the ground surface. The driving direction is therefore usually vertical when installed. However, there are also 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.

[0013] In the context of the present disclosure, a longitudinal extension of a sheet pile is understood to mean the extension in the driving direction or parallel to the driving direction.

[0014] 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.

[0015] Within the scope of the present disclosure, it is preferred if 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. In particular, it is preferred if all elements of the sheet pile assembly have a cross-section that is substantially constant along the longitudinal extent.

[0016] The sheet piles can be hot-rolled or cold-rolled. Hot-rolled sheet piles are preferred.

[0017] A U-sheet pile is understood in particular to be a sheet pile which has a substantially U-shaped cross-section. In particular, 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.

[0018] The open side of a U-sheet pile is the side on which the U formed by the U-sheet pile is open.

[0019] A Z-sheet pile is understood, in particular, to mean a sheet pile having a cross-section with a shape similar to the letter Z. In particular, the Z-sheet pile has two straight sections, which can also be referred to as flanges and which are aligned parallel to one another, namely the first section and the second section of the central sheet pile, and a middle section which runs obliquely to the first and the second section and which is preferably also straight.

[0020] It is preferred that 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. In particular, it is preferred that all structural elements of the sheet pile assembly comprise or consist of steel.

[0021] The sheet pile arrangement can in particular form a partial section of a sheet pile wall.

[0022] 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, and 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.Another advantage is that U-sheet piles are generally easier to manufacture and cheaper, so that the sheet pile arrangement as a whole is relatively easy to manufacture and relatively inexpensive to implement.

[0023] Preferably, 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.

[0024] Preferably, the sheet pile arrangement comprises exactly three, i.e. no more and no fewer than three, sheet piles.

[0025] According to a particularly preferred embodiment, it is provided that the longitudinal extent of the central sheet pile deviates from the longitudinal extent of the first 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 first outer sheet pile, and is preferably shorter than the longitudinal extent of the first outer sheet pile.

[0026] 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.

[0027] It is particularly preferred that 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.

[0028] 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.

[0029] 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.

[0030] It is particularly preferred that 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.

[0031] It is particularly preferred that the longitudinal extent of the 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.

[0032] It is particularly preferred that the central sheet pile and the first outer sheet pile and the second outer sheet pile each have an upper end and a lower end, wherein the upper end of the central sheet pile and the upper end of the first outer sheet pile and the upper end of the second outer sheet pile are arranged at a height such that the upper end of the central sheet pile and the upper end of the first outer sheet pile and the upper end of the second outer sheet pile are flush with each other.

[0033] Preferably, the central sheet pile, the first outer sheet pile, and the second outer sheet pile are arranged relative to one another such that the upper ends of these sheet piles terminate along a horizontal plane. The lower ends of these sheet piles, however, are not arranged on a horizontal plane, since the lower end of the central sheet pile is thus arranged at a vertical distance from the lower ends of the first outer sheet pile and the second outer sheet pile.

[0034] It is particularly preferred that the lower end of the central sheet pile is arranged at a distance from the lower end of the first outer sheet pile and from the lower end of the second outer sheet pile with respect to the driving direction, wherein preferably the lower end of the first outer sheet pile and the lower end of the second outer sheet pile are arranged at the same height.

[0038] It is particularly preferred that the central sheet pile has a first section on which a first coupling means extending along the longitudinal extent of the central sheet pile is arranged, and wherein the central sheet pile has a second section on which a second coupling means extending along the longitudinal extent of the central sheet pile is arranged, and wherein the first outer sheet pile has a first section on which a first coupling means extending along the longitudinal extent of the first outer sheet pile is arranged, and wherein the first outer sheet pile has a second section on which a second coupling means extending along the longitudinal extent of the first outer sheet pile is arranged, and wherein the second outer sheet pile has a first section,on which a second coupling means extending along the longitudinal extent of the second outer sheet pile is arranged, and wherein the second outer sheet pile has a second section on which a second coupling means extending along the longitudinal extent of the second outer sheet pile is arranged.

[0039] The coupling means of the first outer sheet pile, the coupling means of the second outer sheet pile and the coupling means of the central sheet pile extend in the direction of the respective longitudinal extent, preferably parallel to each other.

[0040] A coupling means is understood in particular to mean a connecting section of a sheet pile, wherein a coupling means is particularly designed to establish a positive connection with another coupling means, which can be arranged on a sheet pile or a connecting element. The coupling means are preferably designed to establish a Larssen interlock connection. A Larssen interlock is a form of interlock connection known and widespread in the field of sheet piling, with which, for example, sheet piles can be connected to one another. The coupling means are preferably arranged at the two end sections of the first and second section of the respective sheet pile, so that the first section, the middle section, and the second section of the respective sheet pile are arranged between the coupling means.

[0041] It is particularly preferred that the first outer sheet pile on the side of the first coupling means of the central sheet pile is connected to the central sheet pile, in particular directly or by means of a connecting element.

[0042] A connecting element is understood in particular to be a component designed to connect two coupling means to one another. The connecting element is preferably designed to connect a U-sheet pile with a Z-sheet pile or with a U-sheet pile. The connecting element is understood in particular not to be a sheet pile. The connecting element is, in its extension transverse to the longitudinal extension, preferably several times smaller than the sheet piles present in the sheet pile arrangement. The connecting element can, for example, have a cross-section shaped essentially like the lowercase letter omega. However, the connecting element can also have a different shape.

[0043] It is particularly preferred that the second outer sheet pile on the side of the second coupling means of the central sheet pile is connected to the central sheet pile, in particular directly or by means of a connecting element.

[0044] In addition or alternatively to a connecting element arranged between the first outer sheet pile and the central sheet pile, a connecting element, which can be designed in the same way, can be arranged between the second outer sheet pile and the central sheet pile.

[0045] It is particularly preferred that the connecting element has a longitudinal extension extending parallel to the driving direction, which is substantially the same length as the longitudinal extension of the central sheet pile or substantially the same length as the longitudinal extension of the first outer sheet pile and the longitudinal extension of the second outer sheet pile.

[0046] It is particularly preferred that the first coupling means of the central sheet pile is designed to create a Larssen interlock connection. It is particularly preferred that the second coupling means of the central sheet pile is designed to create a Larssen interlock connection.

[0047] It is particularly preferred that the first coupling means of the first outer sheet pile is designed to create a Larssen interlock connection. It is particularly preferred that the second coupling means of the first outer sheet pile is designed to create a Larssen interlock connection.

[0048] It is particularly preferred that the first coupling means of the second outer sheet pile is designed to create a Larssen interlock connection. It is particularly preferred that the second coupling means of the second outer sheet pile is designed to create a Larssen interlock connection.

[0049] A Larssen interlock is a well-known and widely used interlock connection in sheet pile walls, which can be used, for example, to connect sheet piles. The coupling means are preferably arranged at the two end sections of the first and second sections, so that the first section, the middle section, and the second section of the respective sheet pile are arranged between the coupling means.

[0050] As an alternative to such a design of the coupling means, the coupling means or part of the coupling means can also be designed to establish a head-claw type connection. In particular, the first coupling means of the central sheet pile can be designed to establish a head-claw type connection. In particular, the second coupling means of the central sheet pile can be designed to establish a head-claw type connection. In particular, the first coupling means of the first outer sheet pile can be designed to establish a head-claw type connection.

[0051] A head-and-claw connection is understood in particular to be a connection for connecting two adjacent sheet piles or a sheet pile with a connecting element, in which a claw-shaped section and a head-shaped section engage with each other. Head-and-claw connections are known in English as "ball-and-socket" connections. Such "ball-and-socket" connections are characterized by the fact that a claw (socket) as a female connection profile is engaged with a head (ball) as a male connection profile in order to connect two sheet piles to each other or a connecting element to a sheet pile.

[0052] It is particularly preferred that the first outer sheet pile is designed as a U-sheet pile and the second outer sheet pile is designed as a U-sheet pile, and wherein the first outer sheet pile and the second outer sheet pile are arranged such that the open side of the first outer sheet pile and the open side of the second outer sheet pile point in different directions.

[0053] Preferably, the open side of the first outer sheet pile and the open side of the second outer sheet pile are each arranged so as to be curved outward. Preferably, the first outer sheet pile is arranged rotated by 180° relative to the second outer sheet pile with respect to an axis running parallel to the longitudinal extension.

[0054] It is particularly preferred that the first outer sheet pile be designed as a straight sheet pile and the second outer sheet pile be designed as a straight sheet pile. Alternatively to the first and second outer sheet piles being designed as U-shaped sheet piles, these sheet piles can also be designed as straight sheet piles.

[0055] It is particularly preferred that a first outer connecting element is connected to the first coupling means of the first outer sheet pile, wherein the first outer connecting element has a first connecting portion which is designed to establish a positive connection with the first coupling means of the first outer sheet pile and wherein the first outer connecting element has a second connecting portion which is designed to establish a head-claw type connection.

[0056] It is particularly preferred that the second connecting portion of the first outer connecting element is head-shaped or claw-shaped to produce a head-claw type connection.

[0057] It is further preferred that a second outer connecting element is connected to the second coupling means of the second outer sheet pile, wherein the second outer connecting element has a first connecting portion which is designed to establish a positive connection with the second coupling means of the second outer sheet pile and wherein the second outer connecting element has a second connecting portion which is designed to establish a head-claw type connection.

[0058] It is particularly preferred that the second connecting portion of the second outer connecting element is head-shaped or claw-shaped to produce a head-claw type connection.

[0059] Preferably, the second connecting portion of the first outer connecting element and the second connecting portion of the second outer connecting element are configured such that one of the two connecting portions is claw-shaped and the other of the two connecting portions is head-shaped. With such a configuration, multiple sheet pile wall assemblies can be connected to one another in a particularly advantageous manner using head-claw type connections, in which the first outer connecting element of one sheet pile assembly is connected to a second outer connecting element of another sheet pile assembly.

[0060] According to a further aspect, the object mentioned above is achieved by a sheet pile wall comprising a plurality of sheet pile assemblies as described here, wherein the sheet pile assemblies each comprise exactly three sheet piles, namely the central sheet pile, the first outer sheet pile, and the second outer sheet pile. The sheet pile assemblies are preferably arranged next to one another in such a way that the first outer sheet pile is connected to the second outer sheet pile of the adjacently arranged sheet pile assemblies directly or by means of at least one outer connecting element. The sheet pile assemblies preferably have exactly three, i.e., no more and no fewer than three, sheet piles.

The first outer sheet pile is designed as a U-shaped sheet pile, wherein the U-shaped sheet pile is arranged such that it is curved outwards with respect to the center line S, which is arranged parallel to a sheet pile wall extension direction.

The second outer sheet pile 30 has a longitudinal extension running parallel to the driving direction E.

This second coupling means 30e is designed to establish a Larssen lock connection. A central section 30c is arranged between the first section 30b and the second section 30d.

[0068] The sheet pile arrangement 1 further comprises a central sheet pile 10. The central sheet pile 10 is arranged between the first outer sheet pile 20 and the second outer sheet pile 30 and is connected to these two sheet piles. The central sheet pile 10 is designed as a Z-sheet pile, wherein the Z-sheet pile is arranged such that it extends through the center line S. The central sheet pile 10 has a longitudinal extent running parallel to the driving direction E. On a first section 10b of the central sheet pile 10, a first coupling means 10a is arranged, extending parallel to the longitudinal extent of the central sheet pile 10.

[0069] In the exemplary embodiment shown here, a connecting element 40 is provided for the connection between the first outer sheet pile 20 and the central sheet pile 10, which connecting element has a first coupling means 41 and a second coupling means 42, wherein the first coupling means 41 of the connecting element 40 forms a positive connection with the second coupling means 20e of the first outer sheet pile 20 and the second coupling means 42 of the connecting element 40 forms a positive connection with the first coupling means 10a of the central sheet pile 10.

[0070] In the exemplary embodiment shown here, however, no further connecting element is provided for the connection between the central sheet pile 10 and the second outer sheet pile 30.

[0071] Fig. 1b shows a schematic perspective view of the Fig. 1a. The first outer sheet pile 20 has a longitudinal extension L2 running parallel to the driving direction E. The second outer sheet pile 30 has a longitudinal extension L3 running parallel to the driving direction E. The central sheet pile 10 has a longitudinal extension L1 running parallel to the driving direction E.

The longitudinal extension L3 of the second outer sheet pile 30 extends from the upper end E31 of the second outer sheet pile 30 to the lower end E32 of the second outer sheet pile 30.

[0073] The longitudinal extension L1 of the central sheet pile 10 differs from the longitudinal extension L2 of the first outer sheet pile 20 and from the longitudinal extension L3 of the second outer sheet pile 30 in that the longitudinal extension L1 of the central sheet pile 10 is 20% shorter than the longitudinal extension L2 of the first outer sheet pile 20 and than the longitudinal extension L3 of the second outer sheet pile 30. The longitudinal extension L4 of the connecting element 40 corresponds to the longitudinal extension L1 of the central sheet pile 10.

[0074] Fig. Figure 2a shows a schematic cross-sectional view of a second embodiment of a sheet pile arrangement 1. The second embodiment of a sheet pile arrangement 1 shown here is essentially like the one described in connection with the Fig. 1a and Fig. 1b. Therefore, for this second embodiment, reference is essentially made to the statements made above regarding the first embodiment. The only difference compared to the first embodiment is that the central sheet pile 10 has a longer longitudinal extension L1 compared to the longitudinal extension L2 of the first outer sheet pile 20 and compared to the longitudinal extension L3 of the second outer sheet pile.

[0075] The longitudinal extension L1 of the central sheet pile 10 therefore deviates here - as in Fig. 2b - from the longitudinal extension L2 of the first outer sheet pile 20 and from the longitudinal extension L3 of the second outer sheet pile 30 in such a way that the longitudinal extension L1 of the central sheet pile 10 is 20% longer than the longitudinal extension L2 of the first outer sheet pile 20 and than the longitudinal extension L3 of the second outer sheet pile 30. The longitudinal extension L4 of the connecting element 40 corresponds to the longitudinal extension L2 of the first outer sheet pile 20.

[0076] Fig. 3a shows a schematic cross-sectional view of a third embodiment of a sheet pile arrangement 1. The third embodiment of a sheet pile arrangement 1 shown here is essentially like the one described in connection with the Fig. 1a and Fig. 1b described first embodiment. Therefore, for this third embodiment, reference is essentially made to the statements made above regarding the first embodiment. One difference compared to the first embodiment is that no connecting element is arranged between the first outer sheet pile 20 and the central sheet pile 10, but rather the first outer sheet pile 20 and the central sheet pile 10 are directly connected to one another. Such an arrangement, in which a direct connection is provided between the central sheet pile 10 and the first outer sheet pile 20 and a direct connection between the central sheet pile 10 and the second outer sheet pile 30, and in which no connecting elements are provided for these connections to the central sheet pile 10, can be implemented by means of the Fig. This can be achieved with the U-shaped sheet piles 20, 30 shown in Figure 3a, which have first coupling means and second coupling means rotated by 180° relative to one another. A further difference compared to the first embodiment is that a first outer connecting element 50 is connected to the first outer sheet pile 20, which has a claw-shaped connecting section for establishing a head-claw type connection, and that a second outer connecting element 60 is connected to the second outer sheet pile 30, which has a head-shaped connecting section for establishing a head-claw type connection.

[0077] Fig. 3b shows a schematic perspective view of the Fig. Sheet pile arrangement shown in Figure 3a.

[0078] Fig. Fig. 4a shows a schematic cross-sectional view of a fourth embodiment of a sheet pile arrangement 1. The fourth embodiment of a sheet pile arrangement 1 shown here is essentially like the one described in connection with the Fig. 3a and Fig. 3b. Therefore, for this fourth embodiment, reference is essentially made to the statements made above regarding the third embodiment. The only difference compared to the third embodiment is that the central sheet pile 10 has a longer longitudinal extension L1 compared to the longitudinal extension L2 of the first outer sheet pile 20 and compared to the longitudinal extension L3 of the second outer sheet pile.

[0079] The longitudinal extension L1 of the central sheet pile 10 therefore deviates here - as in Fig. 4b - from the longitudinal extension L2 of the first outer sheet pile 20 and from the longitudinal extension L3 of the second outer sheet pile 30 in such a way that the longitudinal extension L1 of the central sheet pile 10 is 20% longer than the longitudinal extension L2 of the first outer sheet pile 20 and than the longitudinal extension L3 of the second outer sheet pile 30. The longitudinal extension L4 of the connecting element 40 corresponds to the longitudinal extension L2 of the first outer sheet pile 20.

The first outer sheet pile is designed as a straight sheet pile, wherein the straight sheet pile extends parallel to the center line S, which is arranged parallel to a sheet pile wall extension direction. The first outer sheet pile 20 has a longitudinal extension running parallel to the driving direction E. On a first section 20b of the first outer sheet pile 20, a first coupling means 20a extending parallel to the longitudinal extension of the first outer sheet pile 20 is arranged. This first coupling means 20a is designed to establish a head-claw type connection. On a second section 20d of the first outer sheet pile 20, a second coupling means 20e extending along the longitudinal extension of the first outer sheet pile 20 is arranged. This second coupling means 20e is designed to establish a head-claw type connection.A middle section 20c is arranged between the first section 20b and the second section 20d.

[0082] The sheet pile assembly 1 further comprises a second outer sheet pile 30. The second outer sheet pile is also designed as a straight sheet pile, wherein the straight sheet pile extends parallel to the center line S, which is arranged parallel to a sheet pile wall extension direction. The second outer sheet pile 30 has a longitudinal extension running parallel to the driving direction E. On a first section 30b of the second outer sheet pile 30, a first coupling means 30a is arranged, extending parallel to the longitudinal extension of the first outer sheet pile 30. This first coupling means 30a is designed to establish a head-claw type connection. On a second section 30d of the second outer sheet pile 30, a second coupling means 30e is arranged, extending along the longitudinal extension of the second outer sheet pile 30. This second coupling means 30e is designed to establish a head-claw type connection.A middle section 30c is arranged between the first section 30b and the second section 30d.

[0083] The sheet pile assembly 1 further comprises a central sheet pile 10. The central sheet pile 10 is arranged between the first outer sheet pile 20 and the second outer sheet pile 30 and is connected to these two sheet piles. The central sheet pile 10 is designed as a Z-sheet pile, wherein the Z-sheet pile is arranged such that it extends through the center line S. The central sheet pile 10 has a longitudinal extension running parallel to the driving direction E. A first coupling means 10a extending parallel to the longitudinal extension of the central sheet pile 10 is arranged on a first section 10b of the central sheet pile 10. This first coupling means 10a is designed to create a head-claw type connection. A second coupling means 10e extending along the longitudinal extent of the central sheet pile 10 is arranged on a second section 10d of the central sheet pile 10.This second coupling means 10e is designed to establish a head-claw type connection. A middle section 10c is arranged between the first section 10b and the second section 10d.

[0084] In the exemplary embodiment shown here, a connecting element 40 is provided for the connection between the first outer sheet pile 20 and the central sheet pile 10, which connecting element has a first head-shaped coupling means 41 and a second head-shaped coupling means 42, wherein the first coupling means 41 of the connecting element 40 forms a positive connection with the second coupling means 20e of the first outer sheet pile 20 and the second coupling means 42 of the connecting element 40 forms a positive connection with the first coupling means 10a of the central sheet pile 10.

[0085] In the exemplary embodiment shown here, no further connecting element is provided for the connection between the central sheet pile 10 and the second outer sheet pile 30.

[0086] In this fifth embodiment, all connections are designed as head-claw type connections.

[0087] A second outer connecting element 60 is connected to the second outer sheet pile 30. The second outer connecting element 60 is designed like the connecting element 40, i.e., it also has two head-shaped coupling means. By means of this second outer connecting element 60, several Fig. 5a can be connected to one another. Thus, the claw-shaped coupling means 20a of one sheet pile assembly 1 can be connected to the head-shaped coupling means of the second outer connecting element 60 of another sheet pile assembly 1. In this way, a sheet pile wall can be formed with several sheet pile assemblies that are connected to one another.

[0088] Fig. 5b shows a schematic perspective view of the Fig. 5a. The first outer sheet pile 20 has a longitudinal extension L2 running parallel to the driving direction E. The second outer sheet pile 30 has a longitudinal extension L3 running parallel to the driving direction E. The central sheet pile 10 has a longitudinal extension L1 running parallel to the driving direction E. The connecting element 40 has a longitudinal extension L4 running parallel to the driving direction E.

[0089] The longitudinal extension L1 of the central sheet pile 10 extends from the upper end E11 of the central sheet pile 10 to the lower end E12 of the central sheet pile 10. The longitudinal extension L2 of the first outer sheet pile 20 extends from the upper end E21 of the first outer sheet pile 20 to the lower end E22 of the first outer sheet pile 20. The longitudinal extension L3 of the second outer sheet pile 30 extends from the upper end E31 of the second outer sheet pile 30 to the lower end E32 of the second outer sheet pile 30.

[0090] The longitudinal extension L1 of the central sheet pile 10 differs from the longitudinal extension L2 of the first outer sheet pile 20 and from the longitudinal extension L3 of the second outer sheet pile 30 in that the longitudinal extension L1 of the central sheet pile 10 is 20% shorter than the longitudinal extension L2 of the first outer sheet pile 20 and than the longitudinal extension L3 of the second outer sheet pile 30. The longitudinal extension L4 of the connecting element 40 corresponds to the longitudinal extension L1 of the central sheet pile 10.

The sixth embodiment of a sheet pile arrangement 1 shown here is essentially like the one described in connection with the Fig. 5a and Fig. 5b. Therefore, for this sixth embodiment, reference is essentially made to the statements made above regarding the fifth embodiment. The only difference compared to the fifth embodiment is that the central sheet pile 10 has a longer longitudinal extension L1 compared to the longitudinal extension L2 of the first outer sheet pile 20 and compared to the longitudinal extension L3 of the second outer sheet pile.

[0092] The longitudinal extension L1 of the central sheet pile 10 therefore deviates here - as in Fig. 6b - from the longitudinal extension L2 of the first outer sheet pile 20 and from the longitudinal extension L3 of the second outer sheet pile 30 in such a way that the longitudinal extension L1 of the central sheet pile 10 is 20% longer than the longitudinal extension L2 of the first outer sheet pile 20 and than the longitudinal extension L3 of the second outer sheet pile 30. The longitudinal extension L4 of the connecting element 40 corresponds to the longitudinal extension L2 of the first outer sheet pile 20.
