Fluctuation Zone Slope Protection System with Eco-Floating Islands
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The subsidence zone in rivers, lakes, and reservoirs faces challenges such as water and land cross-pollution, water quality deterioration, soil erosion, and difficulty in vegetation growth due to hydrological changes, particularly the fluctuation in water levels, which existing ecological slope protection technologies are not adequately addressing.
Innovation Solution
A fluctuation zone state slope protection system comprising a runoff treatment system with grass edge ditches and water storage ponds, combined with a separable eco-floating island system using eco-gabion substrates and aquatic plants, which purifies and collects storm water, stabilizes soil and water, and adapts to changing backwater levels, enhancing the ecological environment and landscape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional ecological slope protection technology is used, then vegetation growth is supported, but the system cannot effectively respond to water level fluctuations and storm water management
Solution Approach 1:
The eco-floating island system is designed to dynamically adjust its position and structure in response to water level fluctuations. The floating islands can rise and fall with water levels, and the separable design allows the system to adapt its configuration between storm water management mode and backwater response mode, achieving both adaptability and reliability
Solution Approach 2:
The slope protection system is divided into separable components including eco-floating islands, eco-gabion substrates, and modular planting structures. This segmentation allows the system to be reconfigured based on hydrological conditions, enabling effective response to both storm water and backwater scenarios while maintaining ecosystem stability
2Object-generated harmful factors
If the slope protection system is designed for storm water management, then runoff treatment is improved, but the system cannot provide adequate habitat space for organisms during backwater periods
Solution Approach 1:
The eco-floating island system serves multiple functions: it acts as a runoff treatment barrier during storm water events, provides habitat space for plants and organisms during backwater periods, and maintains slope stability throughout. This multi-functionality resolves the contradiction between storm water management and habitat provision
Solution Approach 2:
The system dynamically transitions between storm water management configuration and habitat provision configuration based on water level conditions. During high water levels, the floating islands provide runoff treatment; during lower backwater levels, they provide habitat space, achieving both objectives across different hydrological conditions
3Stability of the object's composition
If fixed ecological structures are installed, then soil stability is maintained, but the system cannot adapt to water level rise and fall cycles
Solution Approach 1:
The eco-floating island system provides a dynamic alternative to fixed structures. The floating islands move with water level changes while maintaining slope protection functionality, and the separable design allows reconfiguration to maintain soil stability across different water levels, achieving both adaptability and stability
Solution Approach 2:
The system uses flexible eco-floating island structures that can deform and adjust to water level changes rather than rigid fixed structures. This flexibility allows the system to adapt to hydrological cycles while maintaining soil stability through the anchoring and structural design of the floating components
