Description

[0001] Sheet pile arrangement and 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.

[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 exposed to high bending and torsional loads. To withstand these loads, high bending and torsional stiffness, in particular a sufficiently high bending moment and a sufficiently high torsional moment, are required. High stiffness can be achieved, for example, by using larger reinforcing elements in the sheet pile wall. For example, O-shaped, i.e., tubular, structures are used as reinforcing elements in the cross-section. These can either be directly connected to one another or combined with

[0005] Sheet piles form a sheet pile wall. In addition to O-shaped reinforcement elements, other shaped reinforcement elements are also used for sheet pile walls, such as double-T beams. However, conventional reinforcement elements have the disadvantage of being very large and relatively heavy, which is why transporting such reinforcement elements to the installation site is typically relatively complex.

[0006] Another disadvantage of known reinforcement elements is that they cannot be stacked very efficiently for transport, so there is typically a lot of empty space during transport and therefore transport cannot be carried out very efficiently.

[0007] Another disadvantage of conventional reinforcement elements is that, due to their large cross-section, they are often difficult to drive into the subsoil. Driving devices capable of exerting particularly high forces are often required to insert the reinforcement elements into the subsoil.

[0008] 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 for a sheet pile wall, by means of which a sheet pile wall that can withstand high mechanical loads can be produced with reduced effort.

[0009] 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 at least four U-sheet piles, wherein each of the U-sheet piles is connected to two other U-sheet piles of the at least four U-sheet piles, wherein the U-sheet piles are each connected to one another by means of connecting elements, wherein the U-sheet piles each have a longitudinal extension direction which extends parallel to a driving direction, and wherein the U-sheet piles are arranged such that they are arranged transversely to the driving direction along a circle.

[0010] Accordingly, a sheet pile arrangement is provided with at least four U-shaped sheet piles that are connected to one another by means of connecting elements, wherein the U-shaped sheet piles are each connected to two adjacent U-shaped sheet piles of the sheet pile arrangement such that the U-shaped sheet piles are arranged in a circle. The U-shaped sheet piles form, in particular, a closed, circular structure in the direction transverse to the longitudinal extent. One advantage of such a sheet pile arrangement is that the sheet pile arrangement can be composed of several individual U-shaped sheet piles. This makes it possible for the individual U-shaped sheet piles of the sheet pile arrangement to be transported to the installation site without being connected to one another.Compared to large profiles, especially those with an O-shaped cross-section, the sheet pile arrangement can be transported both more easily and more efficiently, as the U-shaped sheet piles can be stacked on top of each other to save space.

[0011] A further advantage of such a sheet pile arrangement is that the U-sheet piles can be driven into the ground particularly easily due to the relatively small cross-section of a single U-sheet pile compared to larger structures, such as an O-shaped structure. The sheet pile arrangement has the advantage that the individual U-sheet piles of the sheet pile arrangement do not have to be driven into the ground at the same time, but can also be driven separately. Such separate driving of the U-sheet piles can be particularly advantageous when the ground is relatively hard or when larger objects, such as larger stones, are present in the ground that require a higher driving force.

[0012] A further advantage of such a sheet pile arrangement is that U-shaped sheet piles are typically relatively inexpensive to manufacture, whereas other profiles, such as O-shaped profiles, are typically significantly more expensive to produce. A sheet pile arrangement proposed here can therefore provide a relatively cost-effective arrangement.

[0013] 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.

[0014] For the purposes of the present disclosure, the longitudinal extension of a sheet pile is understood to mean the extension in the driving direction or parallel to the driving direction. A longitudinal extension direction refers, in particular, to the direction along such a longitudinal extension.

[0015] 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.

[0016] 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 the 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.

[0017] The sheet piles can be hot-rolled or cold-rolled. Hot-rolled sheet piles are preferred.

[0018] A U-sheet pile is understood in particular to be 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° 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.

[0019] An open side of a U-sheet pile means the side on which the U formed by the U-sheet pile is open. A connecting element is understood to be a component designed to connect two sheet piles to one another. The connecting elements are preferably designed to connect one U-sheet pile to another U-sheet pile. The connecting element is understood to be, in particular, not 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 that is shaped essentially like the lowercase letter omega. However, the connecting element can also have a different shape.

[0020] The connecting elements are preferably designed to connect two sheet piles, in particular two U-shaped sheet piles, to each other. Preferably, the extension of the connecting elements in the direction transverse to the longitudinal extension of the U-shaped sheet piles is several times smaller than the extension of the U-shaped sheet piles in the direction transverse to the longitudinal extension of the U-shaped sheet piles.

[0021] Preferably, the U-shaped sheet piles in the sheet pile arrangement do not all have the same length. In this case, the U-shaped sheet piles are of different lengths. One advantage of such an arrangement, in which the U-shaped sheet piles are not exactly the same length, is that it allows for material savings and, on the other hand, material only needs to be provided where it is needed.

[0022] Preferably, a sealant is arranged along the connection between the U-shaped sheet piles and the connecting elements. Such a sealant serves, in particular, to fluid-tightly seal the structure transversely to the longitudinal direction. Using such a sealant, a fluid-tight structure can be provided in a particularly advantageous manner. A further advantage of such a sealant is that the structures do not have to be welded together along their entire longitudinal extent. Rather, the connecting sections can either not be welded at all or only be welded at specific points and / or in sections. This allows the sheet pile wall to be produced within a shorter time.

[0023] It is preferred that the U-sheet piles and the connecting elements of the sheet pile arrangement comprise or consist of steel. In particular, it is preferred that all structural elements of the sheet pile arrangement comprise or consist of steel. It is particularly preferred that the sheet pile arrangement has a maximum of ten U-sheet piles, preferably a maximum of eight U-sheet piles, particularly preferably exactly four U-sheet piles. Preferably, the sheet pile arrangement has a maximum of ten U-sheet piles, which are connected to one another by means of connecting elements and are arranged in a circle transverse to the longitudinal direction. Preferably, the sheet pile arrangement has a maximum of eight U-sheet piles, which are connected to one another by means of connecting elements and are arranged in a circle transverse to the longitudinal direction.Preferably, the sheet pile arrangement comprises a maximum of six U-shaped sheet piles, which are interconnected by means of connecting elements and arranged in a circle transverse to the longitudinal direction. Most preferably, the sheet pile arrangement comprises exactly four U-shaped sheet piles, which are interconnected by means of connecting elements and arranged in a circle transverse to the longitudinal direction.

[0024] It is particularly preferred that the connecting elements, by means of which the at least four U-shaped sheet piles are connected to one another, have a substantially omega-shaped cross-section. The term "cross-section" is understood to mean, in particular, a cross-section perpendicular to the driving direction. A substantially omega-shaped configuration is understood to mean, in particular, a configuration in which the cross-section is shaped essentially like the initial letter "omega." However, it is also conceivable for the connecting element to have a different cross-sectional shape.

[0025] It is particularly preferred that each of the at least four U-sheet piles is designed such that a first coupling means extending parallel to the longitudinal extent is arranged on a first section of the U-sheet pile and a second coupling means extending along the longitudinal extent is arranged on a second section of the U-sheet pile.

[0026] It is particularly preferred that the first coupling means of the U-sheet piles are connected to the second coupling means of the adjacent U-sheet piles by means of the connecting elements.

[0027] A coupling means is understood to mean, in particular, 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 can, for example, be designed to establish a Larssen interlock connection. A Larssen interlock is a form of interlock connection known and widespread in the field of sheet pile walls, 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 sections of the respective sheet pile, such that the first section, the middle section, and the second section of the respective sheet pile are arranged between the coupling means.

[0028] It is particularly preferred that the at least four U-sheet piles are each arranged rotated relative to one another with respect to the direction of their longitudinal extent, wherein preferably the at least four U-sheet piles are each arranged rotated by 90° with respect to the direction of their longitudinal extent with respect to the two U-sheet piles which are connected to the respective U-sheet pile.

[0029] It is particularly preferred that the at least four U-sheet piles are each arranged so as to be curved outwards in such a way that the curvature of the U-sheet piles is each curved away from a central axis lying between the U-sheet piles.

[0030] Preferably, the open sides of the at least four U-shaped sheet piles are aligned toward the central axis. The open side of a U-shaped sheet pile refers to the side where the U formed by the U-shaped sheet pile is open.

[0031] It is particularly preferred that on two opposite U-sheet piles of the at least four U-sheet piles, a connecting component is arranged for connection to a further sheet pile arrangement, in particular a sheet pile arrangement as described here, or to a sheet pile, in particular a Z-shaped sheet pile or a U-sheet pile,

[0032] A Z-shaped sheet pile, which can also be referred to as a Z-shaped sheet pile or a Z-sheet pile, is to be understood in particular as a sheet pile which has a cross-section with a shape similar to the letter Z. In particular, the Z-shaped 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 Z-shaped sheet pile, and a middle section which runs obliquely to the first and the second section and which is preferably also straight. It is particularly preferred that the connecting components are each designed to establish a connection with another sheet pile arrangement, in particular a sheet pile arrangement as described here, or with a sheet pile, in particular a Z-shaped sheet pile or a U-sheet pile.

[0033] It is particularly preferred that a connecting component for connection to a sheet pile, in particular a Z-shaped sheet pile, is arranged on at least one of the connecting elements, preferably on several of the connecting elements, and is connected, preferably welded, to the connecting element.

[0034] Preferably, the connecting component is designed to create a head-claw type connection. The connecting component is preferably designed as a claw-shaped connecting component or as a head-shaped connecting component.

[0035] A particular advantage of this design is that complex sheet pile structures that meet specific requirements can be created without the need to weld the U-shaped sheet piles together. Since welding the U-shaped sheet piles together is not necessary, construction is significantly simpler and faster. Furthermore, it is possible to detach the connections and reuse the sheet piles and other components in a different arrangement if necessary.

[0036] According to a further aspect, the aforementioned object is achieved by a sheet pile wall extending along a sheet pile wall extension direction, wherein the sheet pile wall comprises a plurality of sheet pile assemblies arranged along the sheet pile wall extension direction as described herein. Preferably, the sheet pile wall has at least two sheet pile assemblies arranged along the sheet pile wall extension direction.

[0037] It is particularly preferred that on each of the sheet pile assemblies, on two opposite U-shaped sheet piles of the at least four U-shaped sheet piles of the respective sheet pile assemblies, a connecting component is arranged for connection to another sheet pile assemblies, in particular a sheet pile assemblies as described here, or to a sheet pile, in particular a Z-shaped sheet pile or a U-shaped sheet pile. It is particularly preferred that the plurality of sheet pile assemblies are connected to one another by means of the connecting components of the sheet pile assemblies, wherein preferably no sheet piles are arranged between the interconnected sheet pile assemblies.

[0038] One advantage of this type of sheet pile wall is that it can withstand particularly high mechanical loads. The entire sheet pile wall can be constructed using only U-shaped sheet piles, connecting elements, and connecting components.

[0039] It is particularly preferred that Z-shaped sheet piles are connected to the connecting components of the sheet pile arrangements, wherein preferably between two of the sheet pile arrangements exactly two Z-shaped sheet piles are arranged, which are connected to each other.

[0040] It is particularly preferred that a sheet pile module is arranged between two of the sheet pile arrangements, wherein the sheet pile module has a plurality of sheet piles, preferably exactly three sheet piles, particularly preferably two Z-shaped sheet piles and a U-shaped sheet pile arranged between the Z-shaped sheet piles or two U-shaped sheet piles and a Z-shaped sheet pile arranged between the U-shaped sheet piles.

[0041] Such an arrangement with sheet pile arrangements and a sheet pile module has proven particularly advantageous. With such a sheet pile wall, particularly high rigidity and strength can be achieved through the sheet pile arrangements. On the other hand, the sheet pile module provides an equally resilient intermediate piece. In particular, the provision of exactly three sheet piles, especially when these are two U-shaped sheet piles and one Z-shaped sheet pile, or two Z-shaped sheet piles and one U-shaped sheet pile, results in particularly advantageous torsional rigidity of the structure.

[0042] Preferably, a sheet pile arrangement and a sheet pile module always extend alternately along the sheet pile wall extension direction.

[0043] It is particularly preferred that two sheet pile modules are arranged between two of the sheet pile arrangements, wherein the sheet pile modules each have a plurality of sheet piles, preferably exactly three sheet piles each, particularly preferably two Z-shaped sheet piles each and a U-shaped sheet pile arranged between the Z-shaped sheet piles or two U-shaped sheet piles each and a Z-shaped sheet pile arranged between the U-shaped sheet piles.

[0044] Such an arrangement with sheet pile arrangements and a sheet pile module has proven particularly advantageous. With such a sheet pile wall, particularly high rigidity and strength can be achieved through the sheet pile arrangements. On the other hand, the two sheet pile modules provide an equally resilient intermediate piece. In particular, the provision of exactly three sheet piles per sheet pile module, and especially when these are two U-shaped sheet piles and one Z-shaped sheet pile, or two Z-shaped sheet piles and one U-shaped sheet pile, results in particularly advantageous torsional rigidity of the structure.

[0045] Preferably, one sheet pile arrangement and two sheet pile modules always extend alternately along the sheet pile wall extension direction.

[0046] According to a further aspect, the object mentioned at the outset is achieved by a method for producing a sheet pile wall driven into a subsoil, preferably a sheet pile wall as described here, the method comprising the following steps: providing at least four U-sheet piles that are not connected to one another at an installation site; driving a first U-sheet pile of the at least four U-sheet piles, preferably in a vertical direction, into a subsoil of the installation site; after driving the first U-sheet pile, driving a second U-sheet pile of the at least four U-sheet piles, preferably in a vertical direction, into the subsoil, wherein the second U-sheet pile is driven next to the first U-sheet pile in such a way that the first U-sheet pile and the second U-sheet pile are connected to one another by means of a connecting element;After driving in the second U-sheet pile, driving in a third U-sheet pile of the at least four U-sheet piles, preferably in a vertical direction, into the subsoil, wherein the third U-sheet pile is driven in next to the second U-sheet pile in such a way that the second U-sheet pile and the third U-sheet pile are connected to one another by means of a connecting element;After driving in the third U-sheet pile, driving in a fourth U-sheet pile of the at least four U-sheet piles, preferably in a vertical direction, into the subsoil, wherein the fourth U-sheet pile is driven in next to the third U-sheet pile in such a way that the third U-sheet pile and the fourth U-sheet pile are connected to one another by means of a connecting element, wherein preferably the fourth U-sheet pile is driven in next to the first U-sheet pile in such a way that the fourth U-sheet pile and the first U-sheet pile are connected to one another by means of a connecting element, wherein preferably the U-sheet piles form a sheet pile arrangement as described here, which is driven into the subsoil.;

[0047] One advantage of this method is that the U-sheet piles are particularly easy to drive into the subsoil due to the relatively small cross-section of a single U-sheet pile compared to larger structures, such as an O-shaped structure. Since the individual U-sheet piles in the sheet pile arrangement are not driven into the subsoil simultaneously, but separately, the required driving forces are lower than for larger structures. This advantage is particularly evident when the subsoil is relatively hard or when larger objects, such as larger stones, are present in the subsoil that require a higher driving force.

[0048] A further advantage of such a method is that the sheet pile arrangement only has to be assembled on site from several individual U-sheet piles and not before the sheet pile arrangement is transported.

[0049] According to a further aspect, the object mentioned at the outset is achieved by a method for producing a sheet pile wall driven into a subsoil, preferably a sheet pile wall as described here, comprising the following steps: Providing at least four U-sheet piles that are not connected to one another at an installation site; Connecting a second U-sheet pile of the at least four U-sheet piles to a first U-sheet pile of the at least four U-sheet piles by means of a connecting element; Connecting a third U-sheet pile of the at least four U-sheet piles to the second U-sheet pile of the at least four U-sheet piles by means of a connecting element;Connecting a fourth U-sheet pile of the at least four U-sheet piles to the third U-sheet pile of the at least four U-sheet piles by means of a connecting element, wherein preferably the fourth U-sheet pile is also connected to the first U-sheet pile by means of a connecting element, wherein preferably the first, second, third and fourth U-sheet piles form a sheet pile arrangement as described here;After connecting the at least four U-sheet piles to one another, the at least four interconnected U-sheet piles are driven into the subsoil, preferably in a vertical direction, wherein the interconnected U-sheet piles preferably form a sheet pile arrangement as described here, which is driven into the subsoil. One advantage of such a method is that the sheet pile arrangement only has to be assembled on site from several individual U-sheet piles and not before the sheet pile arrangement is transported. This makes it possible for the individual U-sheet piles of the sheet pile arrangement to be transported to the installation site in a non-connected state. In comparison to large profiles, in particular those with an O-shaped cross-section, the transport of the sheet pile arrangement is therefore both easier and more efficient, since the U-sheet piles can be transported stacked on top of one another to save space.

[0050] Preferably, a circular guide is provided when driving the U-shaped sheet piles of the sheet pile assembly into the subsoil. Such a guide ensures that the U-shaped sheet piles are driven into the correct position and that the U-shaped sheet piles of the sheet pile assembly are then arranged in a circular pattern when driven in.

[0066] Fig. 1 shows a schematic cross-sectional view of a sheet pile arrangement 10 with four U-shaped sheet piles 11, 12, 13, 14. The sheet pile arrangement 10 is intended for a sheet pile wall. The sheet pile arrangement 10 comprises exactly four U-shaped sheet piles 11, 12, 13, 14, wherein each of the U-shaped sheet piles 11, 12, 13, 14 is connected to two other U-shaped sheet piles 11, 12, 13, 14 of the four U-shaped sheet piles 11, 12, 13, 14. The U-shaped sheet piles 11, 12, 13, 14 are each connected to one another by means of connecting elements 1112, 1213, 1314, 1411. The U-sheet piles 11 , 12, 13, 14 each have a

[0067] Longitudinal direction of extension which extends parallel to a ramming direction E. The U-sheet piles 11, 12, 13, 14 are arranged such that they are arranged transversely to the ramming direction E along a circle K. The center of the circle lies on the central axis M, which is arranged centrally between the U-sheet piles 11, 12, 13, 14 of the sheet pile arrangement 10 and extends parallel to the ramming direction E. The sheet pile arrangement has a width B and a depth T transversely to the longitudinal direction of extension.

[0068] The connecting elements 1112, 1213, 1314, 1411, by means of which the four U-sheet piles 11, 12, 13, 14 are connected to one another, are essentially omega-shaped in cross section.

[0069] The U-sheet piles 11, 12, 13, 14 are designed such that a first coupling means 11a, 12a, 13a, 14a extending parallel to the longitudinal extent is arranged on a first section 11b, 12b, 13b, 14b of the U-sheet piles 11, 12, 13, 14 and a second coupling means 11e, 12e, 13e, 14e extending along the longitudinal extent is arranged on a second section 11d, 12d, 13d, 14d of the U-sheet piles 11, 12, 13, 14. The U-sheet piles 11, 12, 13, 14 are also designed such that a middle section 11c, 12c, 13c, 14c is arranged between the first section 11b, 12b, 13b, 14b and the second section 11d, 12d, 13d, 14d of the U-sheet piles 11, 12, 13, 14. The first coupling means 11a, 12a, 13a, 14a of the U-sheet piles 11, 12, 13, 14 are each designed to create a Larssen interlock connection.The second coupling means 11e, 12e, 13e, 14e of the U-shaped sheet piles 11, 12, 13, 14 are each designed to create a Larssen lock connection. However, in the embodiment shown here, no Larssen lock connection is created with the connecting elements 1112, 1213, 1314, 1411, but rather a differently designed connection. In this case, the first coupling means 11 a, 12a, 13a, 14a of the U-sheet piles 11, 12, 13, 14 are connected by means of the connecting elements 11 12, 1213, 1314, 1411 to the second coupling means 11 e, 12e, 13e, 14e of the adjacent U-sheet piles 11, 12, 13, 14.

[0070] Connecting components 111, 131 for connecting to another sheet pile arrangement 10 or to a sheet pile are arranged on two opposite U-shaped sheet piles 11, 13 of the four U-shaped sheet piles 11, 12, 13, 14. The connecting components 111, 131 are preferably welded to the corresponding U-shaped sheet pile 11, 13 along the longitudinal direction. The connecting component 111 is shaped as a claw-shaped connecting component and is designed to establish a head-claw type (“ball-and-socket” connection) with a head-shaped connecting portion of a sheet pile or a connecting component. The connecting component 131 is shaped as a head-shaped connecting component and is designed to establish a head-claw type (“ball-and-socket” connection) with a claw-shaped connecting portion of a sheet pile or a connecting component.

[0071] Fig. 2 shows a sheet pile wall 2 with several interconnected sheet pile assemblies 10. The sheet pile assemblies 10 are each designed as described in connection with Fig. 1. The sheet pile assemblies 10 are directly connected to one another, wherein the connecting components 111, 131 of the adjacently arranged sheet pile assemblies form a head-claw type connection. The sheet pile assemblies 10 extend along a sheet pile wall extension direction R. For the sake of clarity, only three interconnected sheet pile assemblies 10 are shown here. However, it is entirely possible and advantageous if several further sheet pile assemblies 10 are connected to one another along the sheet pile wall extension direction R, so that a plurality, for example at least 10, preferably at least 20, of sheet pile assemblies 10 are connected to one another, which extend along the sheet pile wall extension direction R.

[0072] Fig. 3 shows a sheet pile wall 2 with several sheet pile assemblies 10 and sheet piles 20 arranged therebetween in a first embodiment. The sheet pile assemblies 10 are each designed as described in connection with Fig. 1. Between the sheet pile assemblies 10, exactly two Z-shaped and interconnected sheet piles 20 are arranged, which together form a sheet pile module 1c. The Z-shaped sheet piles 20 are connected to the connecting components 111, 131 of the sheet pile assemblies 10. The arrangement shown here can be repeated as often as desired in the sheet pile wall extension direction R, in particular as often as required for the sheet pile wall 2 to be produced.

[0073] Fig. 4 shows a sheet pile wall with several sheet pile assemblies 10 and sheet piles 20, 30 arranged therebetween in a second embodiment. The sheet pile assemblies 10 are each designed as described in connection with Fig. 1. Between the sheet pile assemblies 10, exactly three sound piles 20, 30 are arranged, which are arranged in a particularly preferred configuration. Two Z-shaped sheet piles 20 are provided, which are connected to the connecting components 111, 131 of the sheet pile assemblies 10, with a U-shaped sheet pile 30 being arranged between the two Z-shaped sheet piles 20. The two Z-shaped sheet piles 20 with the U-shaped sheet pile 30 arranged therebetween form a sheet pile module 1b. The arrangement shown here can be repeated as often as required in the sheet pile wall extension direction R, in particular as often as is required for the sheet pile wall 2 to be constructed.
