DETAILED DESCRIPTION

[0035] FIG. 1 shows a cross-sectional view of a first embodiment 1 of a sheet pile module according to the disclosure. The sheet pile module 1 has three sheet piles, a central sheet pile 2, wherein the central sheet pile 2 is a Z-sheet pile, a first U-sheet pile 4 on one side of the central sheet pile 2, shown on the left of the central sheet pile 2 in FIG. 1, and a second U-sheet pile 6 on the other side of the central sheet pile 2, shown on the right of the central sheet pile 2 in FIG. 1.

[0036] The central sheet pile 2 has a first coupling segment 2a with first coupling feature 2b along a first longitudinal edge 2c of the central sheet pile 2. The central sheet pile 2 also has a second coupling segment 2d with second coupling feature 2e along a second longitudinal edge 2f of the central sheet pile 2. The second longitudinal edge 2f lies opposite the first longitudinal edge 2c and is formed parallel to it along the central sheet pile 2. A Z-shaped intermediate segment 2g of the central sheet pile 2 is located between the first coupling segment 2a and the second coupling segment 2d and connected to these two, such as by integrally forming. The Z-shaped intermediate segment in turn has a flat central plate 2g.

[0037] In the embodiment shown, both the first coupling feature 2b and the second coupling feature 2e are formed as a Larssen interlock.

[0038] The first U-sheet pile 4 is connected to the first coupling feature 2b and also has a Larssen interlock on its edge 4a facing the central sheet pile 2. The second U-sheet pile 6 is connected to the second coupling feature 2e on its side facing the central sheet pile 2 and also has a Larssen interlock on its edge 6a facing the central sheet pile 2 in the embodiment shown in FIG. 1.

[0039] In the embodiment shown in FIG. 1, the first U-sheet pile 4 also has a Larssen interlock on its edge 4b facing away from the central sheet pile 2 in order to be able to be connected to a further sheet pile module 1 if necessary. For the same reason, the second U-shaped sheet pile 6 of the embodiment shown in FIG. 1 also has a Larssen interlock on its edge 6b facing away from the central sheet pile 2.

[0040] The first U-shaped sheet pile 4 has an open side 4c. The second U-shaped sheet pile 6 has an open side 6c. As shown in the embodiment of FIG. 1, the open side 4c of the first U-sheet pile 4 and the open side 6c of the second U-sheet pile 6 face in the same direction.

[0041] The sheet pile module 1 may be prefabricated. This means that the sheet pile module 1 is assembled from the three sheet piles 2, 4 and 6 away from the construction site, i.e. away from a place of use, and transported to the construction site as an assembled sheet pile module.

[0042] FIG. 2 shows a perspective view of the sheet pile module 1 of FIG. 1.

[0043] FIG. 3 shows a cross-section of a sheet pile wall 8 formed from a total of six sheet pile modules 1 of FIGS. 1 and 2. In the embodiment of the sheet pile wall 8 shown in FIG. 3, the open sides 4c and 6c of the U-sheet piles 4 and 6 of adjacent sheet pile modules 1 face in opposite directions.

[0044] FIG. 3a shows a supplemented first embodiment 1 of a sheet pile module with three sheet piles. The three sheet piles 2, 4 and 6 of the supplemented sheet pile module l are identical to the sheet piles 2, 4 and 6 of the sheet pile module 1 of the first embodiment shown in FIGS. 1 and 2. However, the sheet pile module 1 of the supplemented first embodiment according to FIG. 3a is supplemented on the side of the first U-sheet pile 4 shown on the left in FIG. 3a facing away from the central sheet pile 2. Because a coupling feature 17a designed as a connecting element of the ball-and-socket type is located on its edge 4b facing away from the central sheet pile 2. The coupling feature 17a is provided as a separate connecting element. Alternatively, but not shown, the coupling feature 17a can also be integrally formed on the left edge 4b of the first U-sheet pile 4. The coupling feature 17a has a ball end 17b which extends away from the first U-sheet pile to which it is connected.

[0045] Accordingly, on the edge 6b of the second U-sheet pile 6 facing away from the central sheet pile 2 shown on the right in FIG. 3a, a coupling feature 17c is attached to the side of the second U-sheet pile 6 facing away from the central sheet pile 2 with the aid of a Larssen interlock. The coupling feature 17c is also provided as a separate connecting element. Alternatively, but not shown, the second coupling feature 17c can also be integrally formed with the edge 6b of the second U-sheet pile 6 facing away from the central sheet pile 2. At its end facing away from the second U-sheet pile 6, the second coupling feature 17c has a socket end 17d which extends away from the second U-sheet pile 6, to which it is connected via the Larssen interlock on the edge 6b.

[0046] The supplemented first embodiment l of the sheet pile module according to the disclosure as shown in FIG. 3a can be constructed in the same way as the sheet pile module 1 according to FIG. 3 with adjacent sheet pile modules l to form a sheet pile wall.

[0047] FIG. 3b shows the cross-sectional view of FIG. 3a with a dashed line 9 to illustrate the plane of the maximum of the tensile forces acting on the sheet pile wall 8. It can be seen that in this arrangement of the sheet piles 2, 4, 6 to form a sheet pile wall 8, the plane 9 of the maximum of the tensile forces acting on a sheet pile wall 8 assembled does not run through any of the coupling feature for connecting the sheet piles 2, 4, 6, i.e. not through the weakest points of the sheet pile module 1 and thus of the sheet pile wall 8. Rather, this plane 9 of the greatest tensile forces runs only through flat central plates 2g of the central Z-sheet piles 2 of the sheet pile modules 1. In this way, the present disclosure provides a particularly durable sheet pile wall 8.

[0048] FIG. 4 shows a cross-section of a second embodiment of a sheet pile module 10. The sheet pile module 10 may include three sheet piles, a central sheet pile 12, wherein the central sheet pile 12 is formed as a U-sheet pile, a first Z-sheet pile 14 attached to one side of the central sheet pile 12 shown in FIG. 4 on the left of the central sheet pile 12 and a second Z-sheet pile 16 attached to the other side of the central sheet pile 12 shown in FIG. 4 on the right of the central sheet pile 12.

[0049] The central sheet pile 12 has a first coupling segment 12a with first coupling feature 12b along a first longitudinal edge 12c of the central sheet pile 12. The central sheet pile 12 further includes a second coupling segment 12d with second coupling feature 12e along a second longitudinal edge 12f of the central sheet pile 12. The second longitudinal edge 12f lies opposite the first longitudinal edge 12c and is formed parallel thereto along the central sheet pile 12. A U-shaped intermediate segment 12g of the central sheet pile 12 is located between the first coupling segment 12a and the second coupling segment 12d and connected to these two, preferably integrally.

[0050] In the embodiment shown in FIG. 4, both the first coupling feature 12b and the second coupling feature 12e are designed as a Larssen interlock.

[0051] The first Z-sheet pile 14 is connected to the first coupling feature 12b and also has a Larssen interlock on its edge 14a facing the central sheet pile 12. The second Z-sheet pile 16 is connected to the second coupling feature 12e on its side facing the central sheet pile 12 and also has a Larssen interlock on its edge 16a facing the central sheet pile 12 in the embodiment shown in FIG. 4.

[0052] In the embodiment shown in FIG. 4, the first Z-sheet pile 14 also has a Larssen interlock on its edge 14b facing away from the central sheet pile 12 in order to be able to be connected to a further sheet pile module 10 if necessary. For the same reason, the second Z-sheet pile 16 of the embodiment shown in FIG. 4 also has a Larssen interlock on its edge 16b facing away from the central sheet pile 12.

[0053] The central U-shaped sheet pile 12 has an open side 12h. The first Z-shaped sheet pile 14 has an inner side 14c which faces away from the open side 12h of the central sheet pile 12. The second Z-shaped sheet pile 16 has an inner side 16c, which also points away from the open side 12h of the central sheet pile 12.

[0054] The sheet pile module 10 can be prefabricated. This means that the sheet pile module 10 is assembled from the three sheet piles 12, 14 and 16 away from the construction site, i.e., away from a place of use, and is transported to the construction site as an assembled sheet pile module. FIG. 5 shows a perspective view of the sheet pile module 10 of FIG. 4.

[0055] FIG. 6 shows a cross-section through a sheet pile wall 18, which is formed from a total of six sheet pile modules 10 as shown in FIGS. 4 and 5. In the sheet pile wall 18 of FIG. 6, open sides 12h of the U-shaped sheet piles 12 of adjacent sheet pile modules 10 also point in opposite directions.

[0056] FIG. 6a shows a cross-section of a supplemented second embodiment 10 of a sheet pile module. The sheet pile module 10 according to FIG. 6a has sheet piles 12, 14 and 16 identical to the sheet piles 12, 14 and 16 of the sheet pile module 10 of FIG. 4. However, the sheet pile module 10 is supplemented in the same way at its edges by ball-and-socket coupling features 17a, 17b, 17c and 17d, as described in detail with reference to FIG. 3a.

[0057] The supplemented sheet pile module 10 of FIG. 6a can be assembled to form a sheet pile wall 18, as shown in FIG. 6.
