Road Gutter Dust Collection via Rotatable Cover Plug
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing urban road drainage systems are inefficient in automatically cleaning roads using natural wind, traffic whirlwind, and rainwater, and lack features such as improved firmness, simple construction, and low maintenance costs, which affect driving safety and increase mechanical or manual cleaning needs.
Innovation Solution
A road dust collection and drainage canal system comprising a U-shaped drainage ditch and a T-shaped cover plug with an inverted U-front surface, where the cover plug is embedded in the ditch and supported by platforms, forming a dust absorption channel that collects dust and debris under natural forces, and is designed to withstand vehicle impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a traditional drainage ditch system is used, then the construction is simple, but the road cleaning function is poor and dust accumulates on the road
Solution Approach 1:
The patent combines the drainage ditch with a dust collection function by adding a cover plug that creates a dust absorption channel. The drainage ditch structure is merged with the dust collection system, allowing it to perform both drainage and road cleaning functions simultaneously without requiring separate systems.
Solution Approach 2:
The drainage ditch is transformed into a multi-functional structure that serves both as a drainage system and a dust collection system. The cover plug with its specific geometry enables the structure to collect dust through natural forces while maintaining its drainage capability, making it a universal solution for both purposes.
2Reliability
If the cover plug is designed to withstand vehicle impacts, then the driving safety is improved, but the structural complexity increases
Solution Approach 1:
The cover plug is designed with dynamic characteristics that allow it to rotate around a force bearing point when subjected to vehicle impacts. This rotational movement absorbs impact energy and allows the cover plug to withstand braking forces and rolling forces without requiring overly complex reinforcement structures.
Solution Approach 2:
The cover plug is pre-designed with specific geometric features including the inverted U-shape front surface and T-shape side surface, which are configured in advance to withstand various vehicle forces. The embedded portion and supported portions are predetermined to provide the necessary structural integrity against impacts before they occur.
3Strength
If the cover plug uses additional fixing with cement mortar, then the firmness is improved, but the construction time and cost increase
Solution Approach 1:
The cover plug is designed as a segmented structure with an embedded portion that fits into the drainage ditch and supported portions that rest on the ditch walls. This segmentation allows the cover plug to be installed as a separate component without requiring additional cement mortar fixing, reducing construction time and complexity while maintaining firmness through the embedded design.
4Productivity
If the dust absorption channel is fully enclosed, then the dust collection efficiency is improved, but the maintenance access becomes difficult
Solution Approach 1:
The cover plug is designed to be rotatable around a force bearing point, which allows the dust absorption channel to be dynamically accessible for maintenance. When maintenance is needed, the cover plug can be rotated or removed to provide access to the drainage ditch interior, while during normal operation it remains in position to maintain dust collection efficiency.

AI summary
The invention discloses a road dust collection and drainage canal, wherein a road edge of a road surface is provided with a dust collection and drainage canal which is composed of a U-shaped drainage ditch adjacent to the road edge and a cover cap that covers the drainage ditch, a left end of the cover cap forms a dust absorption cavity with a platform on a left wall of the U-shaped drainage ditch in a suspended manner, a right end of the cover cap is sealed with a platform on a right wall of the U-shaped drainage ditch and one of step facades, and dust and debris on a road get into and fall into a bottom of the U-shaped drainage ditch from the dust absorption cavity under driving of an external force. The road dust collection and drainage canal can effectively reduce a dust load of the road, and guarantees a driving safety and a pedestrian safety.
