Pivoting Sheet Pile Interlock with Hook Strip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing combination sheet pile walls face challenges in pivoting the interlocks of sheet piles and connecting profiled elements, limiting their ability to adjust to uneven ground conditions, which can lead to disengagement and instability during construction.
Innovation Solution
The connecting profiled element features a central strip with a straight inner wall, a 90° angled end section, and a hook strip with a semi-circular and straight section, allowing for pivoting angles of over 60°, creating a three-point connection that prevents disengagement and ensures stability and leak tightness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the interlocks and receiving profiled elements are designed with limited pivoting capability, then the structural integrity is maintained, but the ability to adapt to uneven ground conditions and twisting during ramming is severely restricted
Solution Approach 1:
The receiving profiled element incorporates a hook strip with a semi-circular cross-section that enables dynamic pivoting motion. The interlock can rotate within the receiving profiled element through a wide angle range, allowing the structure to adapt to ground irregularities and twisting forces during ramming while maintaining continuous engagement
Solution Approach 2:
The design changes the geometric parameters of the receiving profiled element, specifically incorporating a hook strip with semi-circular cross-section and quarter-circle transition sections. These parameter changes enable the interlock to pivot through wide angles (greater than 60°) while maintaining structural integrity and preventing disengagement
2Adaptability or versatility
If the receiving profiled element allows wide pivoting angles, then the sheet pile wall can accommodate ground irregularities and twisting, but the complexity of the profiled element design increases
Solution Approach 1:
The receiving profiled element features a hook strip with a semi-circular cross-section and quarter-circle transition sections. These curved geometries naturally guide the pivoting motion and enable wide rotation angles while maintaining a relatively simple overall structure that integrates smoothly into the connecting profiled element
3Stability of the object's composition
If the interlocks are rigidly connected to the receiving profiled elements, then the structural stability is maximized, but the ability to compensate for deviations in target dimensions during construction is lost
Solution Approach 1:
The connection between interlock and receiving profiled element is designed to be dynamically pivotable rather than rigidly fixed. The hook strip geometry allows controlled rotation and movement, enabling the structure to compensate for construction deviations while maintaining overall stability through the three-point connection mechanism

AI summary
A rod-type connecting profiled element (10) for connecting sheet piles to carrier elements comprises a central strip (12) that separates two opposing connecting profiled elements (16, 18), each of which respectively forms a saw (24, 42). One connecting profiled element is embodied as a plug-in profiled element (16) for the carrier element and the other connecting profiled element is embodied as a receiving profiled element (18) for connecting a sheet pile. The central strip (12) comprises, on the side of the receiving profiled element (18), a central section (14) having a straight plane inner wall (30) to which a first short end section (32) is connected on one side, said short end section protruding past the central section (14) at an angle of approximately 90°, and being connected thereto by means of a transition section (36) having an inner wall with a cross-section that follows a quadrant. A hook strip (34) is arranged on the other side of the plane central section (14) as a second end section oriented in the same direction as the first end section (32).
