Integral Side Slope Structure for Soil-Covered Tank Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing side slope structures of soil-covered tanks are prone to instability and erosion due to external factors, leading to potential collapse and leakage, which compromises the safety and integrity of the tank contents.
Innovation Solution
An integral side slope structure is implemented, comprising connecting pieces with cross-connected ribs and reinforcing frameworks with extension rods, which form a multi-layer connecting net to stabilize the soil and prevent erosion, ensuring the tank body remains secure and leak-proof.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complete soil covering is adopted to protect tank bodies, then safety and land utilization are improved, but side slope stability deteriorates due to greater slope angles and complex stress conditions
Solution Approach 1:
The side slope protection structure is segmented into multiple layers of connecting nets made from connecting pieces. Each layer is positioned at different depths within the soil, creating a multi-level reinforcement system that distributes and manages the complex stress conditions at various levels of the slope, thereby maintaining stability while allowing complete soil covering.
Solution Approach 2:
The connecting pieces are nested within the soil matrix, with multiple layers of connecting nets embedded at different depths. This nesting approach integrates the reinforcement structure seamlessly into the soil, allowing the soil to maintain its protective function while the embedded nets provide structural stability to the side slope.
2Ease of manufacture
If conventional side slope protection measures are applied, then construction cost is reduced, but structural integrity deteriorates due to poor connectivity and susceptibility to external factors
Solution Approach 1:
The solution merges multiple functions into the connecting pieces: they provide structural reinforcement, create connectivity between soil layers, and form an integrated network with the tank body. By combining these functions into a single integrated system rather than separate protection measures, the structure achieves high reliability while maintaining cost-effectiveness through standardized components.
Solution Approach 2:
The side slope protection system uses composite construction combining connecting pieces (likely metal or high-strength polymer) with soil material. This composite structure leverages the strength and connectivity of the manufactured connecting pieces while utilizing the natural protective properties of the soil, achieving both structural integrity and cost efficiency.
3Device complexity
If simple connecting structures are used, then device complexity is reduced, but抗erosion capability deteriorates due to insufficient reinforcement against external factors
Solution Approach 1:
The protection system transitions from two-dimensional surface protection to three-dimensional subsurface reinforcement. Multiple layers of connecting nets are positioned at different depths within the soil profile, creating a volumetric reinforcement structure that effectively resists erosion forces from various directions and depths without requiring overly complex surface structures.
