Description

Technical Field

[0001] The present invention relates to a connecting element for a sheet pile wall having a plurality of sheet piles. The present invention also relates to a sheet pile device and a sheet pile wall. Background Art

[0002] Sheet piles and sheet pile walls having sheet piles are in principle known from the prior art, for example from DE 20 2016101 909U1.

[0003] In order to drive sheet piles into a substrate, such as the ground, typically large forces are required. Due to the large forces, usually a high energy requirement is also needed for installing a sheet pile wall.

[0004] Another problem that occurs in known sheet piles and sheet pile walls is that the sheet piles and other elements required for the sheet pile wall, such as connecting elements, also usually have to be transported over long distances to the place of use. Here, usually a high space requirement is needed for transportation, whereby the transportation of the materials required for the sheet pile wall can be logistically costly and high costs may arise here.

[0005] Another problem of known sheet piles and known sheet pile walls is that small deviations from the desired position when positioning the elements of the sheet pile wall during on-site installation or small deviations of the dimensions of the elements required for the sheet pile wall from the desired dimensions are already problematic, because in such cases usually a high work input is required and there is an additional material requirement. Summary of the Invention

[0006] Therefore, the object on which the present invention is based is to provide an improved solution to the problems mentioned. The object of the present invention is in particular to provide a solution by means of which more flexibility and more variant feasibility can be achieved when installing a sheet pile wall, and wherein the space requirement for transporting the elements required for the sheet pile wall is also reduced.

[0007] According to a first aspect, the object is achieved by a connecting element according to claim 1. Accordingly, there is provided a connecting element for a sheet pile wall having a plurality of sheet piles, wherein the connecting element has a longitudinal extension extending parallel to the driving direction, wherein the connecting element has a straight section that extends along a straight line in a direction transverse to the longitudinal extension, wherein the straight section has a first inner side and a first outer side, wherein the connecting element has a connecting section for establishing a connection between the connecting element and the sheet pile, and wherein the connecting section has a second inner side and a second outer side.

[0008] According to the present invention, an external arcuate transition section is provided between a first outer side and a second outer side, wherein the first outer side and the second outer side extend transversely to the longitudinal direction and are arranged substantially orthogonally to each other, and wherein an internal arcuate transition section is provided between a first inner side and a second inner side, wherein the first inner side and the second inner side enclose an angle of less than 90°, wherein the connecting element extends transversely to the longitudinal direction and has a width in a direction parallel to a straight line and a depth orthogonal to the straight line, wherein the connecting section has a minimum width extension and a maximum width extension adjacent to the transition section in a direction parallel to the width, wherein the maximum width extension is larger than the minimum width extension and is up to 3 times thereof.

[0009] The ramming direction should in particular be understood as the direction in which the sheet pile wall and thus also the components extending along the sheet pile wall are introduced into the base, in particular by ramming the sheet pile wall into the ground to introduce it into the base. The ramming direction is in most cases perpendicular to the ground surface. Therefore, the ramming direction is usually vertically oriented in the installation attitude. However, if for example the sheet pile wall or the sheet piles for the sheet pile wall are pressed into a mountain or a hill in order to support a tunnel, for example, there is also a ramming direction extending parallel to the horizontal line. The ramming direction in particular corresponds to the longitudinal extension direction of the sheet pile wall. If the connecting element is installed at the sheet pile wall, the longitudinal extension of the connecting element preferably extends parallel to the longitudinal extension direction of the sheet pile wall. The longitudinal extension or the longitudinal extension direction or the longitudinal axis of the connecting element or the sheet pile or the reinforcing element is understood within the scope of the present disclosure as the extension of the corresponding object in the ramming direction.

[0010] Within the scope of the present disclosure, it is preferred that the cross-section of the connecting element and the cross-section of the sheet pile are substantially constant along the longitudinal extension or the longitudinal extension direction.

[0011] Preferably, the connecting element comprises steel or is made of steel. Preferably, the sheet pile comprises steel or is made of steel.

[0012] The connecting element is in particular configured such that it does not form a form-fitting connection with a connecting element of the same shape.

[0013] The connecting section of the connecting element is preferably configured as a male connecting section. The connecting section is in particular configured to form a connection with the lock of the adjacent Larssen sheet pile. The Larssen lock should in particular be understood as the following hook-shaped strip into which the hook-shaped strip of the sheet pile of the sheet pile wall can engage, wherein the hook-shaped strip extends arcuately from the tab of the connecting element and a mouth opening is provided between the tab and the end section.

[0014] The connecting section preferably has an approximately triangular cross-section transversely to the longitudinal direction, wherein in particular the corners of the triangle are rounded, the corners of the triangle are beveled, and the corners are in the range of the transition region.

[0015] The outer arcuate transition section is formed in particular arcuately extending transversely to the longitudinal direction. The inner arcuate transition section is formed in particular arcuately extending transversely to the longitudinal direction. The first inner side and the second inner side preferably enclose an acute angle, in particular an angle less than 90°, extending transversely to the longitudinal direction. Thereby, the connecting section widens from the transition section towards the second end section. The angle should in particular be understood as the angle between the extension direction extending transversely to the longitudinal direction of the first inner side and the extension direction extending transversely to the longitudinal direction of the second inner side.

[0016] The connecting element has a width in the direction parallel to the straight line and a depth orthogonal to the straight line extending transversely to the longitudinal direction. The connecting section in the width direction has a minimum width extension and a maximum width extension adjacent to the transition section. The minimum width extension should in particular be understood as the extension of the connecting section in the width direction at the following part of the connecting section, at the part where the connecting section transitions into the transition section, where this is preferably the part of the connecting section having the minimum width of the connecting section. In particular, the minimum width extension should be understood as the extension of the width of the connecting section in the region of the transition to the transition section. The maximum width extension should in particular be understood as the extension of the width of the connecting section where the width is maximum, where the maximum width extension is preferably provided at the outer region of the connecting section.

[0017] The advantage of the connecting element described herein is that the connecting element can be connected to the sheet pile and then can form a form-fitting connection together with the sheet pile, and the form-fitting connection has a relatively small share of gaps. Thereby, when the connecting element is rammed in, when the connecting element is connected to the sheet pile, relatively little ground material, such as soil, reaches the gaps of the connection in the region of the connection between the connecting element and the sheet pile. Due to the small share of gaps, the connecting element can be introduced into the base together with the sheet pile with a relatively small force consumption and thus with a relatively small energy consumption.

[0018] Another advantage is that such a connecting element can be used flexibly and with the aid of the connecting element, deviations from the desired position and deviations from the desired dimensions of the elements of the sheet pile wall to be installed can be compensated.

[0019] Another advantage is that the space requirement for the transportation of the connecting element is relatively small.

[0020] Another advantage is the straight non-hook-shaped cross-sectional shape, by means of which a particularly fixed but still flexible connection to the known connection interfaces of the sheet pile can be established in a surprising manner.

[0021] Particularly preferably, the maximum width extension is larger than the minimum width extension, up to 2.5 times, preferably up to 2.2 times, particularly preferably up to 2.1 times, in particular up to 2 times. Particularly preferably, the maximum width extension is approximately twice the size of the minimum width extension.

[0022] According to a preferred embodiment, the angle is less than 75°, preferably less than 65°, particularly preferably less than 60°, and is at least 45°, preferably at least 50°, particularly preferably at least 52°. The angle should in particular be understood as the angle formed by the extension of the first inner side in a direction transverse to the longitudinal direction and the extension of the second inner side in a direction transverse to the longitudinal direction. Particularly preferably, the first inner side and the second inner side are oriented at an angle of 55° relative to each other.

[0023] Particularly preferably, the first inner side and the first outer side are arranged parallel to each other. Preferably, the straight section has a constant thickness.

[0024] Preferably, the straight section has a first end section which preferably extends orthogonally to the straight line and parallel to the longitudinal direction.

[0025] Particularly preferably, the width is greater than the depth.

[0026] Preferably, the width is at least twice as large as the depth, particularly preferably at least three times as large, especially at least four times as large.

[0027] Such a greater width compared to the depth has the advantage that there is no gap between the region of the connecting element and the reinforcing element, where the connecting element can be connected to the reinforcing element. Since such a gap typically acts disadvantageously on the ramming process, especially because more energy is required for ramming thereby, the force consumption and energy consumption for installing the sheet pile wall can be reduced by means of a connecting element configured in this way.

[0028] Particularly preferably, the connecting element consists of a connecting section, a straight section, and a transition section that forms the transition between the connecting section and the straight section.

[0031] Particularly preferably, the second outer side extends straight from the outer arcuate transition section until the chamfer. The second outer side preferably extends transversely to the longitudinal direction of extension without bending or orthogonally to the straight line. The chamfer should in particular be understood as a beveled surface which is produced by machining the edge of the workpiece. The chamfer is particularly used so that a good engagement into the connecting section of the sheet pile can be achieved by the subsequently resulting shape of the connecting section. In addition, sharp edges are avoided by means of the chamfer, thereby reducing the risk of injury during operation.

[0032] Preferably, the second outer side extends transversely to the longitudinal direction of extension at least along half the length of the depth.

[0033] Particularly preferably, the connecting section has a second end section which preferably extends parallel to the straight line, wherein preferably the second end section extends from the chamfer until another arcuate section, wherein the chamfer is connected to the second outer side and the other arcuate section is connected to the second inner side.

[0041] Preferably, the connecting section, the second connecting section and the third connecting section are configured to have the same shape. The connecting section, the second connecting section and the third connecting section preferably have cross-sections configured to have the same shape in a direction extending transversely to the longitudinal direction.

[0090] Figure 1a Cross-sectional view showing a first embodiment of the connecting element 10.

[0091] The connecting element 10 has a longitudinal extension L extending parallel to the ramming direction, and the longitudinal extension is orthogonal to the drawing plane or extends in the viewing direction in the Figure 1a view shown here. The connecting element has a width B transverse to the longitudinal extension L and a depth A orthogonal to the width B. The width B is greater than the depth A.

[0092] The connecting element 10 has a straight section 20 that extends along a straight line G in a direction transverse to the longitudinal extension L. The straight section has a first inner side 21 and a first outer side 22. The first inner side 21 and the first outer side 22 are arranged parallel to each other and extend parallel to the straight line G. The straight section 20 has a first end section 25 that is orthogonal to the first inner side 21 and the first outer side 22. The straight section 20 does not have a bend.

[0093] The connecting element 10 also has a connecting section 30 for establishing a connection between the connecting element and the sheet pile. The connecting section 30 has a second inner side 31 and a second outer side 32. The second inner side 31 and the second outer side extend non-parallel to each other. The connecting section 30 has a second end section 35 which is arranged orthogonally to the second outer side 32. A chamfer 36, i.e. an inclined surface area, is provided between the second end section 34 and the second outer side. An arcuate section 37 is provided in the area between the second end section 35 and the second inner side 31.

[0094] A transition section 40 is provided between the connecting section 30 and the straight section 22. An external arcuate transition section 34 is provided between the first outer side 22 and the second outer side 32, which in the cross-sectional view depicts an arc of a quarter circle, such that the first outer side 22 and the second outer side 32 are arranged orthogonally to each other in the cross-section. An internal arcuate transition section 33 is provided between the first inner side 21 and the second inner side 31, which in the cross-sectional view depicts an arc of a circular section having a size between a semi-circle and a quarter circle. Thus, the first inner side 21 and the second inner side 31 enclose an angle x which is less than 90° but greater than 0°. The angle x preferably corresponds to the angle at which the second inner side 31 is arranged relative to the second end section 35.

[0095] Figure 1b Shows a perspective view of the embodiment of the connecting element 10 shown in Figure 1a The exact length of the connecting element 10 along the longitudinal extension L can be different, as indicated by the two dash-dotted lines. The length of the connecting element 10 in the direction of the longitudinal extension L can in particular be matched to the length required for the sheet pile wall.

[0096] Figure 2 Shows a cross-sectional view of a sheet pile wall having two sheet piles 60 and two reinforcement elements 50. The reinforcement elements 50 are configured as double-T carriers and each have tabs 50b and two flanges 50a. Connecting elements 10 are welded respectively at the outer side of one of the flanges 50a of the double-T carrier. The sheet piles 60 are respectively connected in a form-fitting manner to the connecting sections of the connecting elements 10. An intermediate element 70 is provided between the two sheet piles 60 shown here, which is in turn connected to the sheet piles 60 in a form-fitting manner. The section of the sheet pile wall shown here can be extended arbitrarily by arranging and connecting the elements shown here in the order shown here multiple times side by side.

[0097] Figure 3A cross-sectional view of a sheet pile wall is shown having two sheet piles 60 and two reinforcing elements 55. The reinforcing elements 55 are configured substantially tubular in cross-section. Connecting elements 10 are welded to two opposite outer sides of the reinforcing elements 55. The connecting sections of the connecting elements 10 are respectively in form-fitting connection with the sheet piles 60. An intermediate element 70 is provided between the two sheet piles 60 shown here, and the intermediate element is also in form-fitting connection with the sheet piles 60. The section of the sheet pile wall shown here can be arbitrarily extended by arranging and connecting the elements shown here in parallel multiple times in the order shown here.

[0099] Figure 5 A cross-sectional view of a sheet pile wall is shown having two sheet piles 60 and two reinforcing elements 55. The reinforcing elements 55 are configured substantially tubular in cross-section. Connecting elements 10 are welded to two opposite outer sides of the reinforcing elements 55. However, the connecting sections of the connecting elements are differently oriented, and the connecting sections of the connecting elements 10 are arranged relative to each other rotated 180° perpendicular to the drawing plane. The connecting sections of the connecting elements 10 are respectively in form-fitting connection with the sheet piles 60. The sheet piles 60 are in form-fitting connection with each other. The section of the sheet pile wall shown here can also be arbitrarily extended by arranging and connecting the elements shown here in parallel multiple times in the order shown here. The same applies to other views in which sections of the sheet pile wall are shown.

[0100] Figure 6 Basically shown in Figure 5 is the device shown in. The connecting elements connected to the sheet piles 60 are emphasized in black. Although the connecting sections of the connecting elements 10 are arranged relative to each other rotated 180° perpendicular to the drawing plane, they are arranged along a straight line (shown here as a dashed line).

[0101] Figure 7a A cross-sectional view showing a second embodiment of the connecting element is shown. The connecting element 10 shown here is constructed as the connecting element shown in Figure 1a except that here, in the connecting element shown in Figure 7a the width B is several times larger than the depth A, especially more than four times larger. Having a width B that is so large compared to the depth A has the advantage that there is no gap between the area of the connecting element 10 and the reinforcing element, where the connecting element 10 is connected to the reinforcing element.
