Plastic sheet piles are susceptible to degradation and deformation due to prolonged exposure to UV radiation, leading to a loss of mechanical properties, and are easily damaged during insertion into the ground.
Innovation Solution
A plastic sheet piling panel with elongated chambers separated by partitions, acting as thermal insulators, and closed at the bottom end to prevent soil entry, which maintains mechanical integrity and facilitates insertion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If plastic sheet piles are used instead of steel, then corrosion resistance is improved and weight is reduced, but strength and resistance to damage during insertion deteriorate
Solution Approach 1:
The sheet pile uses a composite structure combining plastic material with integrated reinforcement elements (such as steel bars or fibers) embedded within the plastic body. This composite approach maintains the corrosion resistance and light weight of plastic while adding the strength and damage resistance of metal reinforcement, resolving the contradiction between material benefits and mechanical performance.
2Ease of operation
If the sheet pile is made entirely of plastic material, then ease of installation and cost are improved, but susceptibility to UV degradation and loss of mechanical properties worsen
Solution Approach 1:
The plastic sheet pile incorporates reinforcement elements (steel bars, fibers, or other strengthening materials) within its structure. This composite construction maintains the ease of installation and cost advantages of plastic while adding UV resistance and mechanical property stability through the reinforcement components.
3Ease of manufacture
If the sheet pile panel has an open structure for easy manufacturing, then ease of manufacture is improved, but structural integrity and resistance to deformation during insertion worsen
Solution Approach 1:
The sheet pile panel employs a composite structure where plastic provides the basic form and ease of manufacturing, while embedded reinforcement elements (steel bars, fibers, or strengthening layers) provide the necessary structural integrity and resistance to deformation during insertion and service.
4Ease of manufacture
If the sheet pile is designed with simple geometry, then ease of manufacture and installation are improved, but resistance to bending moments and lateral loads deteriorates
Solution Approach 1:
The sheet pile uses a composite design where the plastic geometry provides ease of manufacture and installation, while strategically placed reinforcement elements (such as steel bars in specific configurations or fiber reinforcement) enhance the resistance to bending moments and lateral loads, allowing simple geometry to achieve complex structural performance.

AI summary
The object of the present invention is to provide a sheet pile resistant to UV radiation, which does not deform or degrade over time due to prolonged exposure to UV radiation, and which does not lose its preferable mechanical properties. The object of the present invention is also to provide a sheet pile that is not easily damaged when being inserted into the ground, despite being made entirely of plastic material. The object of the invention has been achieved by providing an elongated sheet piling panel having a top end and a bottom end for driving the panel into the substrate, and a first wall and a second wall arranged parallelly to each other, whereby the first wall and the second wall are connected by partitions extending between said walls inside the panel and oriented along the length of the panel, from the top end to the bottom end of the panel, thereby forming hollow chambers extending longitudinally. The air contained in the chambers of the sheet piling panel acts as a thermal insulator, what allows the temperature of the wall regions which are not exposed to solar radiation to be lowered enough to prevent deformation of the panel. At the bottom end of the panel the chambers are closed. Closing the chambers at the bottom end of the panel allows to prevent the substrate from entering into the chambers during insertion, and thus prevents damaging the chambers.
