Retaining Wall Strut Coupling Device for Safe Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for installing struts on retaining walls, especially with an embankment in place, are complex, dangerous, and time-consuming, requiring delicate operations at height and risking worker safety and prolonged concrete setting before the upper end is fixed.
Innovation Solution
A support system featuring a coupling device that mechanically connects the strut to the retaining wall, allowing for safer and faster installation by fixing the coupling device first, then securing the upper end of the strut, which simplifies the process and reduces the need for risky operations at height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional strut installation method is used with embankment, then retaining wall stability is ensured, but installation complexity and danger increase significantly
Solution Approach 1:
The invention divides the support system into distinct modular components: a coupling device for wall attachment, a strut with plate, and an embankment. This segmentation allows each component to be optimized independently and simplifies the installation sequence, reducing overall complexity while maintaining stability.
Solution Approach 2:
The coupling device is installed on the retaining wall before the embankment is constructed. This preliminary action provides a pre-established attachment point, eliminating the need for dangerous high-altitude operations later and simplifying the subsequent installation of the strut.
2Strength
If traditional installation method with wedging is used, then strut support is achieved, but installation time and worker exposure to danger increase
Solution Approach 1:
The invention extracts and eliminates the need for temporary wedging elements from the traditional installation process. The coupling device with its integrated fixing mechanism provides direct, permanent support without requiring intermediate temporary supports, thereby reducing installation steps and time.
Solution Approach 2:
The coupling device serves as an intermediary component between the retaining wall and the strut. It provides a standardized interface that simplifies the connection process, eliminating the need for complex field adjustments and temporary wedging operations.
3Stability of the object's composition
If upper end of strut is fixed before concrete pouring, then structural integrity is ensured, but foundation hole collapse risk and concrete drying risk increase
Solution Approach 1:
The coupling device is installed on the retaining wall in advance, before the foundation hole is dug and before concrete pouring. This preliminary installation provides a stable attachment point that eliminates the risk of foundation hole collapse during strut installation and removes the constraint of needing to rush concrete pouring to prevent drying.
4Manufacturing precision
If workers perform fixing operations at height on retaining wall, then proper strut positioning is achieved, but worker safety risks increase
Solution Approach 1:
The coupling device is designed to be installed at ground level on the facing of the retaining wall, creating an equipotential working condition. This eliminates the need for workers to position themselves at dangerous heights while maintaining the precision required for proper strut alignment through the device's geometric design.
