Culvert Construction Using Discarded Vehicle Tires
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for managing discarded vehicle tires, such as shredding and repurposing, do not effectively reduce environmental impact and often require specialized machinery, making them inaccessible and costly for rural culvert manufacturers.
Innovation Solution
A method using discarded tires to construct culverts by separating and verifying tires based on size, drilling holes for metal rods, and compressing them to create a sealed structure that can withstand traffic stress points, reducing the number of tires needed and avoiding leftover tire material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If tire shredding is used to manage discarded tires, then the tires are processed for recycling, but the surface area increases causing greater environmental contact and harm
Solution Approach 1:
The patent divides the tire into functional segments (tread and sidewall) and uses each segment for its optimal purpose. The tread is incorporated into the culvert structure to reduce waste, while the sidewall is used for the culvert body. This segmentation allows complete utilization of the tire without increasing harmful surface area exposure.
2Ease of manufacture
If conventional culvert construction methods are used, then the process is simple and accessible, but leftover tire material remains causing environmental damage
Solution Approach 1:
Instead of discarding any portion of the tire, the patent recovers and utilizes the entire tire. The tread portion is integrated into the culvert structure as a reinforcement layer, ensuring that no tire material is wasted or left to cause environmental harm while maintaining construction simplicity.
3Loss of substance
If specialized machinery is used to construct tires into culverts, then the entire tire can be utilized, but the cost and complexity increase making it inaccessible to rural manufacturers
Solution Approach 1:
The patent enables the tire itself to serve multiple functions in the culvert structure. The tire sidewall forms the culvert body, while the tire tread becomes a reinforcement layer. This self-service approach eliminates the need for specialized machinery to process different tire portions, making the entire tire utilization achievable with simple, accessible tools.
4Ease of manufacture
If tire sidewalls are used separately from treads in culvert construction, then the construction method is simple, but the treads are left unused causing waste
Solution Approach 1:
The patent merges the tire sidewall and tread into a single integrated culvert structure. The sidewall forms the main body while the tread is combined as a reinforcement layer within the same structure. This merging eliminates the need to separate and dispose of treads, maintaining construction simplicity while achieving complete tire utilization.

AI summary
The method teaches constructing a culvert using discarded tires. The culvert's stress points are reinforced by truck tires. Additionally, the integrity of the culvert is kept intact using a predetermined formula for every 10 feet of culvert constructed.
