Surface Covering With Parallel Grooves For Drainage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surface coverings that combine paving and greening, such as grass paving stones, have low dimensional stability and high maintenance costs, especially in areas like tea storage on dikes, where they are prone to damage during rainfall and require cohesive soil for erosion resistance, and slipform pavers produce sealed surfaces that prevent drainage and greening.
Innovation Solution
A surface covering with parallel growth grooves and assigned openings, produced on-site using a slipform paver, allowing for soil introduction and plant rooting, enabling effective drainage and greening while maintaining structural integrity and load-bearing capacity, with vegetation grooves and openings designed for optimal growth and rainwater discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional paving stones with openings are used for greening, then vegetation can grow through the openings, but the dimensional stability is low and maintenance costs are high
Solution Approach 1:
The surface covering is divided into multiple panel sections that can be laid in a modular fashion. Each panel contains growth grooves with openings, allowing vegetation to grow through while maintaining overall structural stability through the segmented design and interlocking arrangement of panels.
Solution Approach 2:
The surface covering has different properties in different regions: the top surface provides a stable paving surface for traffic, while the growth grooves with openings provide localized zones for vegetation growth. This local differentiation allows the same structure to serve both paving and greening functions with appropriate properties in each zone.
2Ease of manufacture
If paving stones are used on soils with low load-bearing capacity, then they can be laid without high-capacity rock mixtures, but the paving stones are driven over and damaged during rainfall clearing
Solution Approach 1:
The panel sections are pre-formed with growth grooves and openings integrated into the structure before installation. This preliminary formation ensures proper positioning and structural integrity during laying, preventing damage during subsequent rainfall clearing operations while maintaining ease of installation on low load-bearing soils.
3Strength
If slipform pavers are used to produce continuous surface coverings, then high load-bearing capacity and flexural strength are achieved, but the surface is sealed and prevents drainage and greening
Solution Approach 1:
The continuous surface covering produced by slipform paver has different properties in different regions: the majority of the surface provides a sealed, high-strength paving surface for load-bearing, while localized growth grooves with openings provide drainage and greening capability. This local differentiation resolves the contradiction between strength and adaptability.
Solution Approach 2:
The surface covering incorporates growth grooves with openings that create porous pathways through the concrete structure. These porous regions allow rainwater to drain through and vegetation to grow, while the surrounding dense concrete maintains high load-bearing capacity and flexural strength.

AI summary
The covering (18) has a plate section comprising vegetation cover grooves (19) running parallel to each other. Openings (20) from an upper side to a lower side of the covering are attached to the grooves, where the covering is produced on ground in a continuous manner. The grooves are arranged in same distance to each other, and are formed as concrete haunches. The openings are arranged in same distance to each other, where connection with the ground is formed in a border region at a lower side of the covering. : Independent claims are also included for the following: (1) a method for producing a surface covering (2) a slipform device comprising a slipform sole.
