Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional passive flexible protection systems for slope geological disasters, such as rockfall and collapse, face challenges including complex anchoring construction, low energy dissipation efficiency, and high maintenance requirements due to strong system integrity and long slip paths of support ropes, leading to inadequate protection and difficulty in expansion or replacement of units.
Innovation Solution
An expandable modular energy-dissipation protection net system featuring support columns with rotation reversing devices, endless support ropes, and independent energy dissipaters, allowing for reduced anchoring points, high energy dissipation efficiency, and modular design for easy assembly and maintenance, with adjustable energy dissipaters and self-balancing constraints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional passive flexible protection system uses linearly-arranged support ropes with multiple anchoring points, then system integrity is strong, but anchoring construction becomes heavy and difficult
Solution Approach 1:
The protection system is divided into independent modular units, each with its own support columns and energy dissipaters. This segmentation reduces the need for extensive anchoring while maintaining system integrity through modular connectivity, directly addressing the contradiction between system stability and construction ease.
2Area of stationary object
If traditional system uses support ropes with long slip path and multiple inter-column interception units, then system coverage is comprehensive, but energy dissipation efficiency decreases
Solution Approach 1:
Energy dissipation is segmented into independent units with localized energy dissipaters positioned at strategic points. This eliminates the need for long slip paths while maintaining comprehensive protection coverage, as each module independently dissipates energy within its designated area.
Solution Approach 2:
Energy dissipaters act as intermediaries between the metal net panels and support columns, providing localized energy absorption without requiring long rope slip paths. This mediator approach maintains protection coverage while significantly improving energy dissipation efficiency.
3Reliability
If traditional passive protection system has strong system integrity with complex connections, then protection is comprehensive, but maintenance and renewal workload increases
Solution Approach 1:
The system is divided into independent modular units that can be individually maintained or replaced. This segmentation maintains comprehensive protection effectiveness while dramatically reducing maintenance workload, as only affected modules need attention rather than the entire system.
Solution Approach 2:
Modular units are designed for easy replacement when worn or damaged. Individual modules can be quickly removed and replaced without affecting the rest of the system, reducing maintenance workload while maintaining overall protection reliability through continuous operational capability.
4Stability of the object's composition
If traditional system uses fixed configuration with many anchoring points, then system stability is high, but expandability and adaptability decrease
Solution Approach 1:
The modular unit design with standardized interfaces enables easy expansion and adaptation to different slope configurations and protection requirements. System stability is maintained through proven modular connections while adaptability increases significantly, allowing the system to be expanded or reconfigured as needed.
Solution Approach 2:
The modular units are designed with universal connections and standardized components that can be applied to various slope types and protection scenarios. This universality maintains system stability through consistent design principles while greatly enhancing expandability and adaptability to different site requirements.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system achieves improved energy dissipation capacity, reduced construction difficulty, and enhanced protection effectiveness by shortening the sliding path of support ropes, enabling independent operation and replacement of units, and allowing for arbitrary expansion of the protection system.
Implementation Method 1
support columns each provided at each of its two ends with a first horizontal longitudinal rotation reversing device on the left side, a second horizontal longitudinal rotation reversing device on the right side and a transverse rotation reversing device on the bottom; a transverse endless support rope wound on the transverse rotation reversing devices located at two ends of the support column; a longitudinal endless support rope wound on adjacent first and second horizontal longitudinal rotation reversing devices
Implementation Method 2
first energy dissipaters connected to the side B; second energy dissipaters connected to the stabilizing and anchoring steel wire rope
Implementation Method 3
the support ropes has a long slip path, and the protection units between columns has many interference factors on the slip of the support ropes, resulting in low energy dissipation efficiency
