Description

[0001] The invention relates to a sheet pile arrangement for a sheet pile wall.

[0002] 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 designed sheet piles are known, for example, from GB 340,853 A and WO 99 / 11869 A1.

[0003] Sheet piles are typically subjected to high mechanical loads throughout their service life. In particular, they are frequently subjected to high bending and torsional loads. To withstand these loads, high bending and torsional stiffness, especially a sufficiently high bending section modulus and a sufficiently high torsional section modulus, are required. High stiffness can be achieved, for example, by using a large material thickness. However, excessive material thickness is disadvantageous because the material requirement and mass are correspondingly high, which increases costs and makes the transport and handling of the sheet pile elements more complex.

[0004] Furthermore, there are often few options for adapting sheet pile walls to the specific site conditions during installation. For example, it may be necessary to withstand high loads at one point on the sheet pile wall while not exceeding a certain width at another point.

[0005] The invention is therefore based on the objective of providing an improved solution that addresses at least one of the aforementioned problems. In particular, it is an objective of the invention to provide a sheet pile arrangement that allows for adaptation to the local conditions and can withstand potentially particularly high mechanical loads.

[0006] According to a first aspect, the problem is solved by a sheet pile arrangement with the features of claim 1. Accordingly, a sheet pile arrangement for a sheet pile wall is provided, the sheet pile arrangement comprising: a first reinforcing element having a longitudinal extension parallel to a driving direction; a first connecting element having a first end section and a second end section, wherein the first end section of the first connecting element is connected to the first reinforcing element along the longitudinal extension of the first reinforcing element, the first connecting element extending from the first end section to the second end section in a direction transverse to the longitudinal extension of the first reinforcing element along a straight line, the second end section of the first connecting element being designed as a head-shaped strip; and a second connecting element,which has a first end section and a second end section, wherein the first end section of the second connecting element is connected to the first reinforcing element along the longitudinal extent of the first reinforcing element, wherein the second connecting element extends from the first end section to the second end section in a direction transverse to the longitudinal extent of the first reinforcing element along a straight line, wherein the second end section of the second connecting element is designed as a head-shaped strip, wherein the first connecting element and the second connecting element are spaced apart from each other and parallel to each other, wherein the first connecting element and the second connecting element are arranged and designed,to accommodate and securely hold a further head-shaped strip extending parallel to the longitudinal extent of the first reinforcing element between the first connecting element and the second connecting element.

[0007] The term "driving direction" refers specifically to the direction in which a sheet pile wall is driven into the ground, and thus also the components extending along the sheet pile wall, in particular the reinforcing elements, connecting elements, and, where applicable, sheet piles, are driven into the ground, especially by driving the sheet pile wall into the soil. The driving direction is typically perpendicular to the ground surface. Therefore, the driving direction is generally vertical in the installed state. 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 to support a tunnel. The driving direction corresponds in particular to the longitudinal direction of the sheet pile wall.

[0008] Within the scope of this disclosure, the longitudinal extent, direction of longitudinal extent, or longitudinal axis of a reinforcing element or connecting element is understood to mean the extent of the respective object in the driving direction. The longitudinal directions of the reinforcing elements and connecting elements of a sheet pile arrangement are, in particular, parallel to each other.

[0009] The term sheet pile extension direction refers specifically to the direction in which the sheet pile wall, or a section thereof, extends transversely to its longitudinal extent. The sheet pile extension direction is therefore orthogonal to the driving direction.

[0010] A reinforcement element is understood to be, in particular, a steel component that can be driven into the ground. Preferably, the first reinforcement element is tubular. The first reinforcement element of the sheet pile assembly preferably has a diameter of at least 300 mm and / or at most 1500 mm. Preferably, all reinforcement elements of the sheet pile assembly have the same diameter.

[0011] A head-shaped strip, also known as a headboard, is specifically a strip whose cross-section is circular, oval, or similar to a circle or oval. The cross-sectional shape can be, for example, circular or oval, or even slightly different with a rounded shape.

[0012] It is particularly preferred that the first reinforcing element comprises or consists of steel.

[0013] The first and second connecting elements are aligned parallel to each other. The first connecting element preferably has a longitudinal extension parallel to the driving direction. The second connecting element preferably has a longitudinal extension parallel to the driving direction.

[0014] Preferably, the first end section of the first connecting element extends along its longitudinal extent. Preferably, the first end section of the first connecting element is connected to the first reinforcing element by means of a weld. Preferably, the first connecting element extends along a plane, so that the first connecting element is preferably not curved but plate-shaped.

[0015] Preferably, the first end section and the second end section of the first connecting element are integral components of the first connecting element. Preferably, the first connecting element is a hot-rolled steel component.

[0016] Preferably, the first end section of the second connecting element extends along its longitudinal extent. Preferably, the first end section of the second connecting element is connected to the first reinforcing element by means of a weld. Preferably, the second connecting element extends along a plane, so that the second connecting element is preferably not curved, but rather flat, i.e., plate-shaped.

[0017] Preferably, the first end section and the second end section of the second connecting element are integral components of the second connecting element. Preferably, the second connecting element is a hot-rolled steel component.

[0018] Preferably, the first connecting element and the second connecting element extend along two planes arranged parallel to each other and spaced apart from each other.

[0019] The second end section of the first connecting element is designed as a head-shaped strip, the head-shaped strip preferably extending along the longitudinal extent of the first connecting element.

[0020] The second end section of the second connecting element is designed as a head-shaped strip, the head-shaped strip preferably extending along the longitudinal extent of the second connecting element.

[0021] The head-shaped strip of the first connecting element and the head-shaped strip of the second connecting element preferably extend parallel to each other.

[0022] The first and second connecting elements are arranged and configured to receive a further head-shaped strip running parallel to the longitudinal extent of the first reinforcing element between the first and second connecting elements and to hold this further head-shaped strip in a form-fitting manner, in particular in such a way that the further head-shaped strip cannot be moved outwards in a direction transverse to the longitudinal extent of the first reinforcing element between the first and second connecting elements. However, it may be possible for the further head-shaped strip to be movable within the area between the first and second connecting elements relative to the first and second connecting elements, in particular in a direction transverse to the longitudinal extent of the first reinforcing element.

[0023] One advantage of such a sheet pile arrangement is that the connecting elements can be manufactured particularly easily and only one type of connecting element is needed to connect adjacent reinforcement elements, so that the entire sheet pile arrangement can be made from only two different components, namely the reinforcement element and the connecting element.

[0024] Another advantage is that all components of such a sheet pile arrangement can be driven into the ground particularly easily because there are no claw-shaped connecting sections that could collide with stones and other objects in the ground, making driving and joining more difficult. Head-shaped piles, on the other hand, can be driven into the ground particularly easily and with less effort and energy.

[0025] Another advantage is that a particularly high torsional and bending stiffness of the sheet pile arrangement can be achieved.

[0026] A further advantage is that a higher strength of connection can be achieved using two such adjacent, head-shaped strips than with a conventional head-claw type connection. This is possible because the first and second connecting elements can be made of any desired thickness and can each be connected to the first reinforcing element on both sides, i.e., along two connection lines, in particular weld lines, especially with welds along these connection lines.

[0027] Another advantage is that such a sheet pile arrangement can be designed in such a way that the additional headboard can be arranged in different positions within the first connecting element and the second connecting element, thereby achieving a particularly high degree of flexibility and adaptability to the local conditions.

[0028] It is particularly preferred that the sheet pile arrangement comprises a further head-shaped strip extending parallel to the longitudinal extent of the first reinforcing element, wherein the further head-shaped strip is arranged between the first connecting element and the second connecting element, wherein the further head-shaped strip is held in a form-fitting manner between the first connecting element and the second connecting element.

[0029] Preferably, the further head-shaped strip is held between the first connecting element and the second connecting element in such a way that the further head-shaped strip cannot be moved out of the area between the first connecting element and the second connecting element in a direction transverse to the longitudinal extent of the first reinforcing element.

[0030] Preferably, the distance between the second end section of the first connecting element and the second end section of the second connecting element is smaller than the extension of the further head-shaped strip in the direction transverse to the longitudinal extension of the reinforcing element and transverse to the lateral extension direction of the first connecting element. This advantageously prevents the further head-shaped strip from being moved between the first and second end sections, thus ensuring that the further head-shaped strip is securely held between the first and second connecting elements.

[0031] Preferably, the further head-shaped strip is a component of a connecting element; more preferably, the further head-shaped strip is formed by a second end section of a connecting element. However, the head-shaped strip can also be designed as the end section of a sheet pile, in particular a Z-shaped sheet pile.
