Pocket Structure for Vegetation in Earth Walls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional earth wall structures lack a reliable and dimensionally accurate framework for permanent vegetation, which limits their aesthetic appeal and erosion stability, especially in permanent structures like Welded Wire Face Reinforced Soil Slopes (WW RSS).
Innovation Solution
A pocket structure for installing vegetation in earth walls, featuring pocket sidewalls with a hook surface for attachment to wire mesh, a liquid receiver for irrigation, and a retainer for fertilizer, allowing for efficient irrigation and plant growth, is introduced. The pocket structure is designed to be installed behind wire mesh and includes a drip channel for effective water distribution and fertilizer delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional earth wall structures are used, then construction simplicity is maintained, but vegetation framework reliability and dimensional accuracy deteriorate
Solution Approach 1:
The earth wall structure is segmented into modular pocket structures that can be independently manufactured and then assembled together. Each pocket structure is a discrete unit with standardized dimensions, allowing for reliable vegetation frameworks while maintaining construction simplicity through modular assembly.
Solution Approach 2:
The invention changes the physical parameters of the wall structure by introducing pre-formed pocket structures with specific geometric parameters (size, shape, attachment features). These parameterized pockets provide dimensional accuracy for vegetation while the modular nature maintains overall construction simplicity.
2Manufacturing precision
If pocket structures are added to earth walls, then vegetation framework reliability improves, but device complexity increases
Solution Approach 1:
The complex requirement for dimensional accuracy in vegetation frameworks is resolved by segmenting the structure into pre-manufactured pocket modules. Each pocket is manufactured with precise dimensions in a controlled environment, ensuring manufacturing precision without requiring complex on-site construction procedures.
Solution Approach 2:
The pocket structures are prepared in advance with precise dimensions and attachment features before installation. This preliminary action of pre-manufacturing the pockets with exact specifications ensures dimensional accuracy is achieved without adding complexity to the actual wall construction process.
3Stability of the object's composition
If wire mesh baskets are used, then erosion stability is provided, but aesthetic appeal and vegetation integration deteriorate
Solution Approach 1:
The invention applies local quality by providing different functions at different locations: the wire mesh provides erosion stability at the structural level, while the attached pocket structures provide aesthetic appeal and vegetation integration at the surface level. Each component addresses the specific requirement of its location.
Solution Approach 2:
The structure combines different materials and components - wire mesh for structural stability and pocket structures for aesthetic and vegetative functions. This composite approach allows the erosion stability function to be separated from the aesthetic function, with each component optimized for its specific purpose.

AI summary
A pocket structure for receiving containerized plants is sloped and hung from a wire of a wire basket. The pocket structure includes hooks, an irrigation fitting and corresponding drip channel to transmit water toward the rear of the pocket, and slots in the walls. The mesh units include braces and are sized for shipping. An earth wall is formed of the mesh units and pockets, and includes irrigation tubing.
