Segmented Anti-noise Wall Recess for Track Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Track body noise protection walls pose safety challenges due to limited space, making it difficult for individuals to escape from approaching rail vehicles, particularly during stressful situations, which complicates track work and rail traffic operations.
Innovation Solution
A track noise barrier component with a recess or escape niche integrated into the design, allowing for easier access and safety, combined with a sound-absorbing wall element that can be arranged at an angle to enhance noise reduction and stability, and made from materials like no-fines concrete for improved sound absorption and structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If track body noise protection walls are arranged close to the track body for effective noise reduction, then noise protection effect is improved and material savings are achieved, but the free space between rail vehicle and noise barrier becomes very limited, making it difficult for people to escape sideways during stressful situations
Solution Approach 1:
The noise protection wall is segmented by introducing recesses that create escape spaces. Instead of a continuous barrier, the wall is divided into sections with periodic recesses that provide lateral escape routes while maintaining overall noise protection functionality.
Solution Approach 2:
The invention adds a lateral escape dimension by creating recesses that extend into the noise barrier structure. This provides a third spatial dimension for escape (lateral movement into recesses) rather than only vertical climbing over the barrier.
2Length of stationary object
If track body noise protection walls are designed with low height to allow passenger view and reduce landscape impact, then aesthetic and functional benefits are achieved, but the walls become harder to overcome during emergency situations
Solution Approach 1:
The low wall is segmented with recesses that provide escape spaces. The segmentation creates localized escape routes without requiring the entire wall to be climbed, making escape feasible despite the low overall height.
Solution Approach 2:
The recesses act as intermediary escape spaces between the track and the wall exterior. These recesses provide a transitional zone that facilitates escape without requiring direct climbing over the wall.
3Reliability
If special safety measures are implemented to enable track workers to leave the track body via the noise protection wall, then worker safety is improved, but track work delays and rail traffic delays increase
Solution Approach 1:
Escape recesses are pre-built into the noise protection wall structure during construction. This preliminary action eliminates the need for temporary safety measures during track work, as the escape routes are already in place and ready for immediate use.
Solution Approach 2:
The noise protection wall itself provides the safety function by incorporating escape recesses, eliminating the need for separate safety infrastructure. The wall serves both its primary noise protection function and the secondary safety escape function.
