Abstract
Description
[0001] Sheet pile wall
[0002] 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.
[0003] 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 arrangements made of differently shaped sheet piles are known, for example, from GB 340,853 A and WO 99 / 11869 A1.
[0004] 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.
[0005] Furthermore, there are often few options for adapting sheet piling to the on-site conditions when installing sheet piling. For example, it may be necessary to absorb high loads at one point of the sheet piling while maintaining a certain width at another point.
[0006] 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 that can withstand particularly high mechanical loads.
[0007] According to a first aspect, the object is achieved by a sheet pile assembly having the features of claim 1. Accordingly, a sheet pile assembly for a sheet pile wall is provided, wherein the sheet pile assembly comprises: a first sheet pile module and a second sheet pile module, wherein the first sheet pile module and the second sheet pile module are arranged next to one another along a sheet pile wall extension direction. The first sheet pile module and the second sheet pile module each comprise exactly three sheet piles, namely: a first Z-sheet pile, which has a longitudinal extension running parallel to a driving direction, wherein a first coupling means extending parallel to the longitudinal extension is arranged on a first section of the first Z-sheet pile, and wherein a second coupling means extending along the longitudinal extension is arranged on a second section of the first Z-sheet pile, a second Z-sheet pile,which has a longitudinal extension running parallel to the driving direction, wherein a first coupling means extending along the longitudinal extension is arranged on a first section of the second Z-sheet pile and wherein a second coupling means extending along the longitudinal extension is arranged on a second section of the second Z-sheet pile, and a central sheet pile which is arranged between the first Z-sheet pile and the second Z-sheet pile and is connected to the first Z-sheet pile and the second Z-sheet pile, wherein the central sheet pile has a longitudinal extension running parallel to the driving direction, wherein a first coupling means extending along the longitudinal extension is arranged on a first section of the central sheet pile and wherein a second coupling means extending along the longitudinal extension is arranged on a second section of the central sheet pile,The central sheet pile is designed as a straight sheet pile or as a U-shaped sheet pile. 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, i.e. in particular the sheet piles, are driven into the subsoil, in particular by driving the sheet pile wall into the ground. The driving direction is typically perpendicular to the ground surface. The driving direction is therefore usually vertical when installed. However, there are also driving directions that are not vertical but run parallel to the horizontal, for example, when sheet pile walls or sheet piles for sheet pile walls are driven into mountains or hills, for example to support a tunnel. The driving direction corresponds in particular to the longitudinal direction of the sheet pile wall.
[0008] For the purposes of the present disclosure, a longitudinal extension or a longitudinal extension direction or a longitudinal axis of a sheet pile or a connecting element is understood to mean the extension of the respective object in the driving direction. The longitudinal extension directions of the sheet piles of a sheet pile module run, in particular, parallel to one another.
[0009] 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.
[0010] It is preferred within the scope of the present disclosure if the cross section of the central sheet pile and the cross section of the first and the cross section of the second Z-sheet pile, and preferably the cross section of the connecting element, are substantially constant along the longitudinal extent or longitudinal extension direction.
[0011] The first sheet pile module and the second sheet pile module are arranged next to each other in particular along the sheet pile wall extension direction and can be connected to each other directly or by means of a connecting element.
[0012] It is preferred that the central sheet pile and the first and second Z-sheet piles comprise or consist of steel. If a connecting element is present, it is preferred that the connecting element comprises or consists of steel. The sheet piles can, in particular, be hot-rolled or cold-formed sheet piles.
[0013] The coupling means of the first Z-sheet pile, the coupling means of the second Z-sheet pile and the coupling means of the central sheet pile extend in the direction of the respective longitudinal extent, in particular parallel to one another.
[0014] A Z-sheet pile is understood, in particular, to be 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, and a central section which runs obliquely to the first and second sections and is preferably also straight.
[0015] A U-sheet pile is understood to mean, in particular, a sheet pile that 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 the second section, 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° to the central section. The second section preferably extends substantially straight and is preferably oriented at an angle of more than 90° to the central section.
[0016] The open side of a U-sheet pile is understood to mean in particular the side of the U-sheet pile on which the U formed by the U-sheet pile is open.
[0017] A coupling means is understood, in particular, to be 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-lock connection or a head-claw type connection.
[0018] A Larssen interlock is a well-known and widely used form of interlocking connection in sheet piling, which can be used to connect sheet piles or a sheet pile with a connecting element. A head-claw connection is particularly a connection known in English as a "ball-and-socket" connection. Such "ball-and-socket" connections are characterized by the fact that a claw, acting as a female connection profile, engages with a head, acting as a male connection profile, particularly to form a positive connection between two sheet piles or a sheet pile with a connecting element.
[0019] 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 are arranged between the coupling means.
[0020] 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 Z-sheet pile to another Z-sheet pile or to a U-sheet pile. A 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 many 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.
[0021] The sheet pile modules each have exactly three sheet piles, i.e., in particular, no more and no fewer than three sheet piles. Preferably, the sheet pile modules each have no further sheet piles apart from the central sheet pile, the first Z-shaped sheet pile, and the second Z-shaped sheet pile.
[0022] One advantage of such a sheet pile arrangement is that, when the Z-shaped sheet piles are arranged with a central sheet pile that is not a Z-shaped sheet pile in between, very high bending and torsional stiffness can be achieved. This makes it particularly advantageous to provide a sheet pile arrangement that can reliably withstand particularly high loads over a long period of time while still maintaining a relatively low material thickness.
[0023] A further advantage of such a sheet pile arrangement is that it can be designed, for example, so that the central sheet pile is a U-shaped sheet pile that is curved outwards or inwards. With an outwardly curved arrangement, particularly good mechanical properties, in particular particularly high bending and torsional rigidity, can be achieved. With an inwardly curved arrangement, on the other hand, a particularly narrow sheet pile wall can be produced in a particularly advantageous manner, which, despite its narrow design, can still withstand relatively high mechanical loads.
[0024] A further advantage is the flexibility of this concept, allowing the sheet pile arrangement to be adapted to specific requirements, for example, even on-site. This allows for particularly flexible selection of a suitable sheet pile arrangement for the installation of a sheet pile wall, and variations between the different arrangements are also possible.
[0025] A particular advantage is that the sheet pile modules can be prefabricated and are also easily transportable. The sheet pile modules, which comprise three sheet piles, can be assembled and then transported to the installation site. At the installation site, the sheet pile modules can then be connected to each other according to local requirements. Alternatively, the sheet pile modules can also be manufactured on site.
[0026] According to a particularly preferred embodiment, the central sheet pile and the first Z-sheet pile are connected by means of a, in particular positive-locking, connection, preferably a Larssen lock connection or a head-claw type connection, between the second coupling means of the first Z-sheet pile and the first coupling means of the central sheet pile.
[0027] Preferably, the central sheet pile and the second Z-sheet pile are connected by means of a, in particular positive-locking, connection, preferably a Larssen lock connection or a head-claw type connection, between the first coupling means of the second Z-sheet pile and the second coupling means of the central sheet pile.
[0028] It is particularly preferred that the first coupling means and the second coupling means of all sheet piles are designed to create a Larssen-lock connection or a head-claw type connection. It is therefore preferred if the coupling means of the first Z-sheet pile, the second Z-sheet pile, and the central sheet pile are each designed to create a Larssen-lock connection or a head-claw type connection.
[0029] Within a sheet pile module, the connection between the central sheet pile and the first Z-sheet pile and / or the connection between the central sheet pile and the second Z-sheet pile can also be established by means of a connecting element arranged between the coupling means.
[0030] It is particularly preferred that the first sheet pile module and the second sheet pile module are connected to one another by means of a, in particular form-fitting, connection between the second Z-sheet pile of the first sheet pile module and the first Z-sheet pile of the second sheet pile module.
[0031] Preferably, the second coupling means of the second Z-sheet pile of the first sheet pile module is connected to the first coupling means of the first sheet pile of the second sheet pile module in a form-fitting manner, in particular by means of a Larssen lock connection or a head-claw type connection.
[0032] The coupling means are to be understood in particular as components of the sheet piles, whereby connections can be made with the coupling means.
[0033] The coupling means are particularly designed to produce a connection, preferably a Larssen lock connection or a head-claw type connection.
[0034] The connections between the coupling elements can also be additionally connected by means of a crimp connection. A crimp connection is understood in particular to mean a connection in which the interconnected coupling elements are joined by plastic deformation.
[0035] It is particularly preferred that the second coupling means of the second Z-sheet pile of the first sheet pile module is connected to the first coupling means of the first sheet pile of the second sheet pile module by means of a connecting element.
[0036] Preferably, the connecting element has a dimension transverse to the longitudinal extension that is several times smaller than that of each of the sheet piles of the first or second sheet pile module. Such a connecting element is therefore not to be understood as a sheet pile, but rather as a component that is significantly smaller transverse to the longitudinal extension.
[0037] The connecting element preferably has a substantially omega-shaped cross-section. A substantially omega-shaped cross-section is understood to mean, in particular, a cross-section shaped similarly to the initial letter omega.
[0038] It is particularly preferred that the central sheet pile extends in a direction transverse to the longitudinal extent from the first section of the central sheet pile along a central section of the central sheet pile to the second section of the central sheet pile, wherein the central section of the central sheet pile is arranged parallel to a sheet pile arrangement centerline running centrally through the sheet pile arrangement. The sheet pile arrangement centerline preferably runs parallel to the sheet pile wall extension direction.
[0039] The sheet pile arrangement centre line is to be understood in particular as a straight line running parallel to the sheet pile wall extension direction, which runs centrally through the sheet pile arrangement in such a way that the extension of the sheet pile arrangement in the direction orthogonal to the sheet pile wall extension direction and orthogonal to the driving direction starting from the sheet pile arrangement centre line is the same on both sides.
[0040] Preferably, the first section of the central sheet pile, the middle section of the central sheet pile and the second section of the central sheet pile are not arranged parallel to each other transversely to the longitudinal direction.
[0041] Preferably, the first section of the central sheet pile is oriented transversely to the longitudinal extension at an angle of at least 60° relative to the sheet pile wall extension arrangement. Preferably, the first section of the central sheet pile is oriented transversely to the longitudinal extension at an angle of at most 90°, in particular at most 80°, relative to the sheet pile wall extension arrangement.
[0042] Preferably, the second section of the central sheet pile is transverse to the
[0043] Longitudinal extension at an angle of at least 60° relative to the
[0044] Sheet pile wall extension arrangement. Preferably, the second section of the central sheet pile is oriented transversely to the longitudinal extension at an angle of at most 90°, in particular at most 80°, relative to the sheet pile wall extension arrangement.
[0045] It is particularly preferred that the central sheet pile be designed as a U-shaped sheet pile that is curved outward relative to the sheet pile arrangement centerline, away from the sheet pile arrangement centerline. The central sheet pile designed as a U-shaped sheet pile is thus oriented so as to be curved outward relative to the sheet pile arrangement centerline.
[0046] Preferably, the central sheet pile of the first sheet pile module designed as a U-shaped sheet pile and the central sheet pile of the second sheet pile module designed as a U-shaped sheet pile are both curved outwards, i.e. curved away from the sheet pile wall extension center line, which runs parallel to the sheet pile wall extension direction.
[0047] It is particularly preferred that the central sheet pile of the first sheet pile module is designed as a U-shaped sheet pile and the central sheet pile of the second sheet pile module is designed as a U-shaped sheet pile, wherein the central sheet pile of the first sheet pile module and the central sheet pile of the second sheet pile module are arranged such that the open sides of the central sheet piles are each arranged on the side of the central sheet piles facing the sheet pile arrangement centerline. With such an orientation with the open sides directed towards the center, the U-shaped sheet piles are arranged so as to be curved outwards.
[0048] The open side of a U-sheet pile is the side on which the U formed by the U-sheet pile is open.
[0049] According to a further embodiment, the central sheet pile is designed as a straight sheet pile, so that the first section of the central sheet pile, the middle section of the central sheet pile and the second section of the central sheet pile are arranged along a straight line which is aligned parallel to the sheet pile extension direction.
[0050] It is particularly preferred that the first Z-sheet pile extends in the direction transverse to the longitudinal extent from the first section of the first Z-sheet pile along a middle section of the first Z-sheet pile to the second section of the first Z-sheet pile, wherein the first section of the first Z-sheet pile and the second section of the first Z-sheet pile are arranged parallel to each other and parallel to the sheet pile arrangement centerline and wherein the middle section of the first Z-sheet pile is not arranged parallel to the first section of the first Z-sheet pile and the second section of the first Z-sheet pile.
[0051] The first section of the first Z-sheet pile and the second section of the first Z-sheet pile are preferably aligned parallel to the sheet pile extension direction.
[0052] Preferably, the middle section of the first Z-sheet pile is oriented transversely to the longitudinal extension at an angle of at least 15°, particularly preferably at least 30°, in particular at least 40° relative to the sheet pile wall extension direction.
[0053] Preferably, the middle section of the first Z-sheet pile is oriented transversely to the longitudinal extension at an angle of at most 80°, particularly preferably at most 70°, in particular at most 60° relative to the sheet pile wall extension direction.
[0054] It is particularly preferred that the second Z-sheet pile extends in a direction transverse to the longitudinal extent from the first section of the second Z-sheet pile along a middle section of the second Z-sheet pile to the second section of the second Z-sheet pile, wherein the first section of the second Z-sheet pile and the second section of the second Z-sheet pile are arranged parallel to each other and parallel to the sheet pile arrangement centerline and wherein the middle section of the second Z-sheet pile is not arranged parallel to the first section of the second Z-sheet pile and the second section of the second Z-sheet pile.
[0055] The first section of the second Z-sheet pile and the second section of the second Z-sheet pile are preferably aligned parallel to the sheet pile extension direction.
[0056] Preferably, the middle section of the second Z-sheet pile is oriented transversely to the longitudinal extension at an angle of at least 15°, particularly preferably at least 30°, in particular at least 40° relative to the sheet pile wall extension direction.
[0057] Preferably, the middle section of the second Z-sheet pile is oriented transversely to the longitudinal extension at an angle of at most 80°, particularly preferably at most 70°, in particular at most 60° relative to the sheet pile wall extension direction. It is particularly preferred that the second Z-sheet pile of the first sheet pile module and the first Z-sheet pile of the second sheet pile module are arranged mirror-symmetrically or point-symmetrically with respect to a plane extending parallel to the driving direction and orthogonal to the sheet pile wall extension direction.
[0058] Preferably, the first Z-sheet pile and the second Z-sheet pile are arranged rotated by 180° relative to each other with respect to the direction of their longitudinal extension.
[0059] It is particularly preferred that the first sheet pile module and the second sheet pile module are identically designed. Preferably, the first sheet pile module and the second sheet pile module each have one or more of the preferred features mentioned in this document.
[0060] Preferably, the first sheet pile module and the second sheet pile module are arranged mirror-symmetrically or point-symmetrically with respect to a plane extending parallel to the driving direction and orthogonally to the sheet pile wall extension direction.
[0061] Preferably, in a mirror-symmetrical arrangement, a connecting element is arranged between the first and the second sheet pile module.
[0062] Preferably, in a point-symmetric arrangement, no connecting element is arranged between the first and the second sheet pile module.
[0063] It is particularly preferred that the sheet pile arrangement comprises a third sheet pile module which is connected to the second sheet pile module and preferably comprises further sheet pile modules, wherein preferably all sheet pile modules are of identical design.
[0064] According to a further aspect, the object mentioned at the outset is achieved by a sheet pile wall comprising a plurality of sheet pile arrangements arranged next to one another and connected to one another as described here.
[0065] According to a further aspect, the object mentioned above is achieved by using a sheet pile arrangement as described here as a component of a sheet pile wall, in particular a sheet pile wall as described here, wherein the sheet pile wall is preferably installed in a subsurface.

[0080] Fig. 1 shows a schematic cross-sectional view of a sheet pile assembly for a sheet pile wall. Fig. 2 shows a perspective view of the sheet pile assembly shown in Fig. 1. The sheet pile assembly shown in Fig. 1 and Fig. 2 comprises a first sheet pile module 1a and a second sheet pile module 1b, wherein the first sheet pile module 1a and the second sheet pile module 1b are arranged side by side along a sheet pile wall extension direction S.
[0081] The first sheet pile module 1a and the second sheet pile module 1b each comprise a first Z-sheet pile 20 having a longitudinal extension L running parallel to a driving direction E. A first coupling means 20a extending parallel to the longitudinal extension L is arranged on a first section 20b of the first Z-sheet pile 20, and a second coupling means 20e extending along the longitudinal extension is arranged on a second section 20d of the first Z-sheet pile 20. The first Z-sheet pile 20 extends transversely to the longitudinal extension from the first section 20b along a central section 20c to the second section 20d.
[0082] The first sheet pile module 1a and the second sheet pile module 1b each further comprise a second Z-sheet pile 30, which has a longitudinal extension running parallel to the driving direction E. A first coupling means 30a extending along the longitudinal extension is arranged on a first section 30b of the second Z-sheet pile 30, and a second coupling means 30e extending along the longitudinal extension is arranged on a second section 30d of the second Z-sheet pile 30. The second Z-sheet pile 30 extends transversely to the longitudinal extension from the first section 30b along a central section 30c to the second section 30d.
[0083] The first Z-sheet pile 20 and the second Z-sheet pile 30 are arranged rotated by 180° relative to each other with respect to the direction of their longitudinal extension.
[0084] Furthermore, the first sheet pile module 1a and the second sheet pile module 1b each comprise a central sheet pile 10, which is arranged between the first Z-sheet pile 20 and the second Z-sheet pile 30 and is connected to the first Z-sheet pile 20 and the second Z-sheet pile 30, wherein the central sheet pile 10 has a longitudinal extent running parallel to the driving direction E, wherein a first coupling means 10a extending along the longitudinal extent is arranged on a first section 10b of the central sheet pile 10 and wherein a second coupling means 10e extending along the longitudinal extent is arranged on a second section 10d of the central sheet pile 10. The central sheet pile 10 is designed as a U-sheet pile in this exemplary embodiment. The central sheet pile 20 extends transversely to the longitudinal extent from the first section 10b along a middle section 10c to the second section 10d.
[0085] The central sheet pile 10 and the first Z-sheet pile 20 are connected by means of a positive-lock Larssen-type connection between the second coupling means 20e of the first Z-sheet pile 20 and the first coupling means 10a of the central sheet pile 10. The central sheet pile 10 and the second Z-sheet pile 30 are connected by means of a positive-lock Larssen-type connection between the first coupling means 30a of the second Z-sheet pile 30 and the second coupling means 10e of the central sheet pile 10.
[0086] The sheet pile modules 1 a, 1 b are connected to one another by means of a positive-locking Larssen lock connection between the second coupling means 30e of the second Z-sheet pile 30 of the first sheet pile module 1 a and the first coupling means 20a of the first Z-sheet pile 20 of the second sheet pile module 1 b.
[0087] The second Z-sheet pile 30 of the first sheet pile module 1 a and the first Z-sheet pile 20 of the second sheet pile module 1 b are arranged point-symmetrically with respect to a plane E1 extending parallel to the driving direction E and orthogonal to the sheet pile wall extension direction S, so that the central sheet piles 10 are arranged alternately to the left and right of the sheet pile arrangement center line M, which runs centrally through the sheet pile arrangement.
[0088] Thus, the first sheet pile module 1a and the second sheet pile module 1b are arranged point-symmetrically with respect to the plane E1. The first sheet pile module 1a and the second sheet pile module 1b are identical in design, but are aligned differently, as described above.
[0089] The central sheet pile 10, designed as a U-shaped sheet pile, is arranged with its sides curved outward relative to the sheet pile arrangement center line M. The open side 11 of the central sheet pile 10, designed as a U-shaped sheet pile, is therefore arranged on the side of the central sheet pile 10 that faces the sheet pile arrangement center line M.
[0090] Fig. 3 shows a schematic cross-sectional view of a sheet pile arrangement with two sheet pile modules 1 a, 1 b. Fig. 4 shows a perspective view of the sheet pile arrangement shown in Fig. 3. The sheet pile modules 1 a, 1 b shown in Fig. 3 and Fig. 4 are designed as described in connection with Fig. 1 and Fig. 2. In contrast to the embodiment shown in Fig. 1 and Fig. 2, however, in the embodiment shown in Fig. 3 and Fig. 4, the first sheet pile module 1 a and the second sheet pile module 1 b are arranged mirror-symmetrically with respect to the plane E1. Thus, both central sheet piles 10 are arranged on one side of the sheet pile arrangement center line M.Between the first sheet pile module 1a and the second sheet pile module 1b, a connecting element 40 with a substantially omega-shaped cross-section is arranged, which is positively connected to the second coupling means 30e of the second Z-sheet pile 30 of the first sheet pile module 1a and which is positively connected to the first coupling means 20a of the first Z-sheet pile 20 of the second sheet pile module 1b. This connecting element 40 makes it possible to arrange the sheet pile modules 1a, 1b relative to one another in this way and to securely connect them to one another.
[0091] Fig. 5 shows a schematic cross-sectional view of a sheet pile arrangement with two sheet pile modules 1 a, 1 b. Fig. 6 shows a perspective view of the sheet pile arrangement shown in Fig. 5. The sheet pile modules 1 a, 1 b shown in Fig. 5 and Fig. 6 are designed similarly to that described in connection with Fig. 1 and Fig. 2. In contrast to the embodiment shown in Fig. 1 and Fig. 2, however, in the embodiment shown in Fig. 5 and Fig. 6, the central sheet piles 10 designed as U-shaped sheet piles are oriented so as to be curved inwards. The open sides 11 of the central sheet piles 10 are therefore not arranged on the side of the central sheet piles 10 facing the sheet pile arrangement center line M, but on the other side of the central sheet piles 10. With a sheet pile arrangement according to this embodiment, a particularly narrow sheet pile wall can be realized.
[0092] Fig. 7 shows a schematic cross-sectional view of a sheet pile arrangement with two sheet pile modules 1 a, 1 b. Fig. 8 shows a perspective view of the sheet pile arrangement shown in Fig. 7. The sheet pile modules 1 a, 1 b shown in Fig. 7 and Fig. 8 are designed as described in connection with Fig. 5 and Fig. 6. In contrast to the embodiment shown in Fig. 5 and Fig. 6, however, in the embodiment shown in Fig. 7 and Fig. 8 the first sheet pile module 1 a and the second sheet pile module 1 b are arranged mirror-symmetrically with respect to the plane E1. Thus, both central sheet piles 10 are arranged on one side of the sheet pile arrangement center line M.Between the first sheet pile module 1a and the second sheet pile module 1b, a connecting element 40 with a substantially omega-shaped cross-section is arranged, which is positively connected to the second coupling means 30e of the second Z-sheet pile 30 of the first sheet pile module 1a and which is positively connected to the first coupling means 20a of the first Z-sheet pile 20 of the second sheet pile module 1b. This connecting element 40 makes it possible to arrange the sheet pile modules 1a, 1b relative to one another in this way and to securely connect them to one another.
