Solution Overview
Problem
Existing construction methods for precast concrete bridges and structures are hindered by heavy, difficult-to-transport components that are prone to damage and require costly, time-consuming in situ construction with high expert supervision.
Innovation Solution
A modular foundation system comprising formwork members, a brace, and a three-dimensional reinforcement cage that integrates with settable material to form a robust support structure, allowing for efficient and economical construction of abutments and foundations for bridges and buildings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If precast concrete components are used for bridge construction, then construction speed is improved, but the components become heavy, difficult to transport and prone to damage
Solution Approach 1:
The foundation structure is divided into modular components including formwork members, braces, and reinforcement cages that can be assembled on-site. This segmentation allows for lighter individual components that are easier to transport while maintaining the overall structural integrity when assembled, resolving the contradiction between construction speed and component weight/transportability.
2Reliability
If in situ construction methods are used, then transportation issues are avoided, but the process becomes time consuming and expensive with high expert supervision requirements
Solution Approach 1:
The formwork members, braces, and reinforcement cages are prepared and positioned in advance before concrete pouring. This preliminary assembly of the structural framework allows for faster construction while maintaining reliability, as the components are pre-configured to ensure proper alignment and structural integrity without requiring extensive on-site supervision.
3Strength
If traditional foundation construction methods are used, then structural integrity is maintained, but the process requires high levels of expert supervision and is costly
Solution Approach 1:
The modular foundation system is designed to be self-aligning and self-assembling through interlocking formwork members and braces that automatically position components correctly during construction. This self-service capability maintains structural integrity through built-in geometric constraints while reducing the need for expert supervision and simplifying the construction process.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The modular system enables fast, easy installation of sturdy abutments and foundations, reducing transportation issues and construction costs, while allowing for simultaneous construction of bridge decks and foundations with improved resistance to load forces.
Implementation Method 1
The brace may provide resistance to the side walls against the force of the settable material being introduced into the space. One such force is the hydrostatic pressure exerted by the fluid concrete on the side walls due to the force of gravity.
Implementation Method 2
The forces within the concrete act across each flat plane of the module and are in equilibrium within the foundation module.
