Segmented Gutter Fastening Device for Roadway Drainage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drainage gutter systems face challenges with the weight and handling of concrete elements, require complex installation processes, and necessitate early attachment of fastening devices, which complicates subsequent construction work and increases costs due to the need for metal cover gratings.
Innovation Solution
A fastening device comprising a coupling device, rod element, and foot device that can be releasably connected, allowing for adjustable installation height and flexible attachment after reinforcing elements are introduced, reducing the complexity of installation and avoiding interference with subsequent work.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional raised fastening devices are attached to the subsoil early in construction, then the channel elements can be securely anchored at the correct height, but preceding and subsequent construction work (laying pipes, cables, reinforcement) becomes significantly more difficult
Solution Approach 1:
The fastening device is divided into separate components: a base element that attaches to the subsoil, rod elements for height adjustment, and coupling devices for attaching channel elements. This segmentation allows the base element to be installed early on the subsoil without interfering with subsequent reinforcement and piping work, while the rod and coupling components can be assembled and attached later at the required height.
2Stability of the object's composition
If concrete channel elements are used, then dimensional stability and secure anchoring are achieved, but weight and susceptibility to impact increase significantly
Solution Approach 1:
The invention uses plastic channel elements combined with a metal fastening device system. The plastic channel elements provide corrosion resistance and reduced weight, while the metal fastening device (base element, rod elements, coupling devices) provides the necessary strength for secure anchoring and structural stability, creating a composite solution that balances weight and strength requirements.
3Ease of operation
If metal cover gratings are installed on plastic channel elements, then a suitable traffic surface is provided, but cost increases significantly and the gratings must be removed and reinstalled during cleaning
Solution Approach 1:
The invention extracts the traffic surface function from the channel element itself by providing a recess in the top surface of the plastic channel element that can receive a cover plate. This allows the channel element to maintain its simple plastic construction for ease of cleaning, while optionally accepting a cover plate to provide a traffic surface when needed. The cover plate can be easily removed for cleaning without affecting the channel element structure.
