Abstract
Description
Field of the Invention
[0001] The present invention relates to a sheet pile device for a sheet pile wall. The present invention also relates to the use of a sheet pile wall and a sheet pile device. Background Art
[0002] Sheet piles and sheet pile walls composed of sheet piles are in principle known from the prior art, for example from DE 202016 101909U1. Sheet pile devices composed of sheet piles of different configurations are known, for example, from GB 340,853A and WO 99 / 11869A1. In the known sheet pile devices, two different sheet pile types are used, which are alternately arranged side by side and connected to each other to form a sheet pile wall section.
[0003] A sheet pile wall typically undergoes high mechanical loads during its service life. In particular, a sheet pile wall usually undergoes high bending and torsional loads. In order to withstand these loads, high bending and torsional rigidity are required, in particular a sufficiently high bending moment resistance and a sufficiently high torque resistance. High rigidity can be achieved, for example, by a large material thickness. However, an excessive material thickness is disadvantageous because the material requirement and mass are correspondingly large, thereby increasing costs and making the transportation and operability of the elements of the sheet pile wall more costly.
[0004] In addition, there is usually little feasibility of matching to given conditions on site when installing a sheet pile wall. Thus, for example, it may be necessary to absorb high loads at one location of the sheet pile wall and not exceed a certain width at another location of the sheet pile wall. Summary of the Invention
[0005] 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 sheet pile device by means of which it is possible to match to the given conditions on site and to withstand possibly particularly high mechanical loads.
[0006] According to a first aspect, the object is achieved by a sheet pile device according to claim 1. For this purpose, a sheet pile device for a sheet pile wall is proposed, the sheet pile device comprising 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 side by side. The first sheet pile module and the second sheet pile module each comprise: a central sheet pile, which is configured as a Z-shaped sheet pile, wherein the central sheet pile has a longitudinal extension extending parallel to the driving direction, wherein a first coupling mechanism extending along the longitudinal extension is provided at a first section of the central sheet pile and wherein a second coupling mechanism extending along the longitudinal extension is provided at a second section of the central sheet pile; a first U-shaped sheet pile, which has a longitudinal extension extending parallel to the driving direction, wherein a first coupling mechanism extending parallel to the longitudinal extension is provided at a first section of the first U-shaped sheet pile and wherein a second coupling mechanism extending along the longitudinal extension is provided at a second section of the first U-shaped sheet pile; a second U-shaped sheet pile, which has a longitudinal extension extending parallel to the driving direction, wherein a first coupling mechanism extending along the longitudinal extension is provided at a first section of the second U-shaped sheet pile and wherein a second coupling mechanism extending along the longitudinal extension is provided at a second section of the second U-shaped sheet pile, wherein the first U-shaped sheet pile is connected to the central sheet pile, in particular directly or by means of a connecting element, on one side of the first coupling mechanism of the central sheet pile and wherein the second U-shaped sheet pile is connected to the central sheet pile on one side of the second coupling mechanism of the central sheet pile, wherein the first U-shaped sheet pile and the second U-shaped sheet pile are arranged such that the open sides of the first U-shaped sheet pile and the second U-shaped sheet pile point in different directions.
[0007] The driving direction is to be understood in particular as the direction in which the sheet pile wall and thus also the components extending along the sheet pile wall are inserted into the ground, in particular by driving the sheet pile wall into the ground. The driving direction is in most cases perpendicular to the ground surface. The driving direction is thus usually oriented vertically in the installed state. However, for example, when the sheet pile wall or the sheet piles for the sheet pile wall are driven into a mountain or a hill in order to support a tunnel, for example, there is also a driving direction extending parallel to the horizontal plane. The driving direction corresponds in particular to the longitudinal extension direction of the sheet pile wall.
[0008] The longitudinal extension or the longitudinal extension direction or the longitudinal axis of a sheet pile or a connecting element is understood within the scope of the present disclosure as the extension of the respective object in the driving direction. The longitudinal extension directions of the sheet piles of the sheet pile modules extend in particular parallel to one another.
[0009] The sheet pile wall extension direction is to be understood in particular as the 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] Within the scope of the present disclosure, it is preferred that the cross-section of the central sheet pile, the cross-sections of the first and second U-shaped sheet piles, and preferably the cross-section of the connecting element are substantially constant along the longitudinal extension or the longitudinal extension direction.
[0011] The first sheet pile module and the second sheet pile module are arranged side by side especially along the sheet pile wall extension direction and can be connected to each other directly or by means of a connecting element.
[0012] Preferably, the central sheet pile and the first and second U-shaped sheet piles comprise steel or are made of steel. Preferably, the connecting element comprises steel or is made of steel.
[0013] The sheet piles can be especially hot-rolled or cold-rolled sheet piles.
[0014] The coupling mechanism of the first U-shaped sheet pile, the coupling mechanism of the second U-shaped sheet pile, and the coupling mechanism of the Z-shaped sheet pile extend in the corresponding longitudinal extension direction, preferably parallel to each other.
[0015] The U-shaped sheet pile should be especially understood as a sheet pile having a substantially U-shaped cross-section. The U-shaped sheet pile especially has a straight middle section and two other sections extending from the middle section, namely the first and second sections which can also be called flanges. The first section preferably extends substantially straight and is preferably oriented at an angle of more than 90° with respect to the middle section. The second section preferably extends substantially straight and is preferably oriented at an angle of more than 90° with respect to the middle section.
[0016] The open side of the U-shaped sheet pile refers to the side at which the U formed by the U-shaped sheet pile is open.
[0017] The Z-shaped sheet pile should be especially understood as a sheet pile whose cross-section is similar to the shape of the letter Z. The Z-shaped sheet pile especially has two straight sections, namely the first section and the second section, which can also be called flanges and are oriented parallel to each other, and a middle section extending obliquely to the first and second sections, and the middle section is preferably also formed straight.
[0018] The coupling mechanism should be especially understood as a connecting section of the sheet pile, wherein the coupling mechanism is especially configured to establish a form-fitting connection with another coupling mechanism, and the other coupling mechanism can be arranged at the sheet pile or the connecting element. The coupling mechanism is preferably configured to establish a Larssen lock connection. The Larssen lock is a known and common form of lock connection in the field of sheet pile walls, and sheet piles can be connected to each other by means of the Larssen lock, for example. The coupling mechanism is preferably arranged at the two end sections of the first and second sections respectively, such that the first section, the middle section, and the second section are respectively arranged between the coupling mechanisms.
[0019] The connecting element should in particular be understood as a component which is configured to connect two coupling mechanisms to each other. The connecting element is preferably configured to connect a U-shaped sheet pile to a Z-shaped sheet pile or to a U-shaped sheet pile. The connecting element should in particular not be understood as a sheet pile. The connecting element is preferably several times smaller in its extension transverse to the longitudinal direction than the sheet piles present in the sheet pile device. The connecting element can for example have a cross-section which is substantially in the shape of the small letter omega (ω). However, the connecting element can also have other shapes.
[0020] One advantage of such a sheet pile device is that in the arrangement of the U-shaped sheet pile which arches outwards, a very high bending and torsional rigidity can be achieved. Thereby, a sheet pile device can be provided in a particularly advantageous manner which can reliably withstand particularly high loads within the scope of a long period of time and in which the material thickness can still remain relatively small.
[0021] Another advantage of such a sheet pile device is that the sheet pile device can also be designed such that the U-shaped sheet pile is arranged to arch inwards. In the case of this arrangement, a narrow sheet pile wall can be manufactured in a particularly advantageous manner which can still withstand relatively high mechanical loads even in the case of a narrow embodiment.
[0022] Another advantage lies in the flexibility of the concept such that the sheet pile device can also be adapted on-site, for example, to the respectively given requirements. Thus, a matching sheet pile device for installing the sheet pile wall can be selected in a particularly flexible manner and variants between different arrangements are also feasible.
[0023] According to a particularly preferred embodiment, the second U-shaped sheet pile of the first sheet pile module is connected to the first U-shaped sheet pile of the second sheet pile module, in particular directly or by means of a connecting element.
[0024] This connection between the first sheet pile module and the second sheet pile module is in particular formed in a form-fitting manner. Here, preferably, the second coupling mechanism of the second U-shaped sheet pile of the first sheet pile module is either connected to the first coupling mechanism of the first U-shaped sheet pile of the second sheet pile module or to a connecting element which is connected to the first coupling mechanism of the first U-shaped sheet pile of the second sheet pile module in a form-fitting manner.

[0034] Particularly preferably, the central sheet pile and the first U-shaped sheet pile are connected to each other, preferably by a direct connection between the first coupling mechanism of the central sheet pile and the second coupling mechanism of the first U-shaped sheet pile or by a connection via a connecting element that is connected, in particular in a form-fitting manner, to the first and second coupling mechanisms of the central sheet pile. In the case of a direct connection, the connection is preferably configured in a form-fitting manner.
[0035] Particularly preferably, the central sheet pile and the second U-shaped sheet pile are connected to each other, preferably by a direct connection between the second coupling mechanism of the central sheet pile and the first coupling mechanism of the second U-shaped sheet pile.

[0036] Particularly preferably, the second U-shaped sheet pile of the first sheet pile module is connected to the first U-shaped sheet pile of the second sheet pile module, preferably by a direct connection between the second coupling mechanism of the second U-shaped sheet pile of the first sheet pile module and the first coupling mechanism of the first U-shaped sheet pile of the second sheet pile module or by a connection via a connecting element that is connected to the second coupling mechanism of the second U-shaped sheet pile of the first sheet pile module and the first coupling mechanism of the first sheet pile of the second sheet pile module.
[0037] Particularly preferably, the first coupling mechanism of the central sheet pile is configured to establish a form-fitting connection, in particular a Larssen lock connection, with the second coupling mechanism of the first U-shaped sheet pile or with a connecting element that is connected in a form-fitting manner to the second coupling mechanism of the first U-shaped sheet pile.
[0038] Preferably, the second coupling mechanism of the central sheet pile is configured to establish a form-fitting connection with the first coupling mechanism of the second U-shaped sheet pile, in particular a Larssen lock connection.

[0040] Particularly preferably, the connecting element has an extension ratio in the direction transverse to the longitudinal extension that is several times smaller than that of each of the sheet piles in the first or second sheet pile module.
[0041] Preferably, the connecting element has a substantially omega-shaped cross-section. A substantially omega-shaped cross-section should in particular be understood as a cross-section configured similarly to the lower-case Greek letter omega (ω).
[0042] Particularly preferably, the central sheet pile extends in the direction transverse to the longitudinal extension from the first section of the central sheet pile along the middle section of the central sheet pile to the second section of the central sheet pile.
[0043] Particularly preferably, the first section of the central sheet pile and the second section of the central sheet pile are arranged parallel to each other and parallel to the sheet pile module extension direction, which extends orthogonally to the driving direction, wherein the middle section of the central sheet pile is not arranged parallel to the first section and the second section of the central sheet pile.
[0044] The sheet pile module extension direction should in particular be understood as the direction in which the respective sheet pile module extends transversely to the longitudinal extension.

In particular, the sheet pile module extension direction passes centrally through the central sheet pile and extends parallel to the first and second sections of the central sheet pile.

[0048] Particularly preferably, the first U-shaped sheet pile and the second U-shaped sheet pile are both curved inwardly, ie, curved toward a center line extending parallel to the sheet pile module extension direction and centrally through the central sheet pile. This arrangement allows installation of a particularly narrow sheet pile wall.
[0049] Particularly preferably, the first U-shaped sheet pile and the second U-shaped sheet pile are both oriented to bend outwards, ie to bend away from a center line extending parallel to the direction of extension of the sheet pile module and centrally through the central sheet pile.
