Retaining Wall Assembly with Embedded Cylindrical Tube
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing culvert installations often require heavy machinery and load-bearing materials, making them difficult to install and costly, while also potentially leading to erosion due to lack of effective soil retention.
Innovation Solution
A retaining wall assembly featuring a concrete retaining wall with a cylindrical tube embedded in the culvert pipe, supported by native soil, which is lightweight, easy to install, and does not require additional load-bearing materials, providing an attractive appearance and erosion prevention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If heavy machinery and load-bearing materials are used for culvert installation, then structural strength and stability are improved, but installation complexity and cost increase
Solution Approach 1:
The retaining wall assembly is divided into separate modular components: a retaining wall portion and a cylindrical tube portion that fits over the culvert pipe. This segmentation allows each component to be manufactured independently with optimized properties and assembled on-site without heavy machinery, resolving the contradiction between structural strength and installation complexity.
Solution Approach 2:
The cylindrical tube portion is designed to fit over the culvert pipe like a nested structure, with the retaining wall portion then fitted over the tube. This nesting arrangement creates a stable, load-bearing assembly that leverages the culvert pipe itself as part of the support structure, eliminating the need for additional load-bearing materials and heavy installation equipment.
2Strength
If additional load-bearing materials are used, then structural support is improved, but material cost and installation effort increase
Solution Approach 1:
The cylindrical tube portion serves multiple functions simultaneously: it provides structural support for the retaining wall, acts as a connection element between the retaining wall and culvert pipe, and serves as a formwork mold during installation. This multi-functionality eliminates the need for separate load-bearing materials, reducing both material cost and installation effort while maintaining structural support.
Solution Approach 2:
The retaining wall assembly is designed to be self-supporting during and after installation. The cylindrical tube and retaining wall portion are configured to interlock and stabilize each other without requiring additional load-bearing materials or heavy machinery, allowing the structure to support itself from the moment of assembly.
3Object-affected harmful factors
If traditional culvert installation methods are used, then erosion control is improved, but installation accessibility and ease of use worsen
Solution Approach 1:
By segmenting the retaining wall and cylindrical tube into separate, lightweight components that can be manually handled, the system maintains effective erosion control through its engineered structure while dramatically improving installation accessibility to the point where nonspecialists can install it without heavy machinery.

AI summary
A retaining wall assembly includes a concrete retaining wall including a bore, and a cylindrical tube fixed in the bore and sized to fixedly fit to a culvert pipe. The cylindrical tube includes a tube body and a flange extending radially outward from the tube body, and the flange is embedded in the retaining wall. The cylindrical tube, when fixedly fit inside the culvert pipe, supports a full weight of the retaining wall. A method of installing the retaining wall to the culvert pipe includes providing the retaining wall assembly, fixedly fitting the cylindrical tube to the culvert pipe, and providing only native soil directly below a bottom edge of the retaining wall.
