Railway Platform Foundation Assembly with Pivot Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing railway line assembly methods, such as those using reinforced concrete foundations and platforms with precise tolerances, are complex and expensive due to procedural complications and the risk of incorrect wheelbase distances, leading to costly corrective interventions and quick deterioration from water infiltration.
Innovation Solution
A foundation and platform assembly system where the platform has passing holes through its thickness, allowing for easy connection via pivot elements inserted into corresponding holes in the foundation, with an adhesive fluid for fixation and an intermediate filling material to prevent water infiltration and ensure stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If platforms are provided with projecting snugs for inserting into holes in the foundation, then connection between foundation and platform is achieved, but the complexity of realization increases and very precise tolerances of distance between wheelbases are required
Solution Approach 1:
Instead of having projecting snugs on the platform that must fit into holes in the foundation (requiring precise tolerances), the invention inverts the approach: holes are cored in the foundation at the moment of installation to match pre-drilled holes in the platform, allowing simple pivot element insertion without requiring precise pre-positioning of projecting snugs
Solution Approach 2:
The holes in the platform are drilled in advance during platform production, allowing the foundation holes to be cored at installation to precisely match them, rather than requiring the platform to have pre-formed projecting snugs that must fit into foundation holes with precise tolerances
2Reliability
If cylinders are realized through casting on site and inserted into holes in the platform, then connection between foundation and platform is achieved, but procedural complications increase and production costs rise
Solution Approach 1:
The invention extracts the connection function from complex cylindrical elements that require on-site casting and precise hole alignment, replacing them with simple pivot elements that pass through pre-drilled holes in the platform and are inserted into holes cored in the foundation at installation
Solution Approach 2:
The invention replaces expensive, complex cylindrical connection elements requiring precise manufacturing with simple, inexpensive pivot elements that can be easily manufactured and installed, accepting that they may need replacement but prioritizing initial installation simplicity and cost-effectiveness
3Object-affected harmful factors
If a layer of bituminous material is interposed between foundation and platforms to prevent water infiltration, then protection against water is achieved, but the material deteriorates quickly due to rain water infiltration into the lodge hole of the cylinder
Solution Approach 1:
The invention removes the vulnerable lodge hole of the cylinder that allowed water to infiltrate and deteriorate the bituminous material layer, replacing the cylindrical connection element with a simple pivot element that passes through pre-drilled holes without creating infiltration pathways
Solution Approach 2:
The invention uses an adhesive fluid as an intermediary substance injected into the foundation holes to secure the pivot elements, replacing the bituminous material layer that was vulnerable to water infiltration, while the pivot element itself acts as a mediator that prevents water pathways
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
Simplifies the assembly process, reduces production costs, and minimizes the risk of incorrect tolerances and platform waste, while maintaining structural stability and preventing water infiltration.
Implementation Method 1
the pivot element is to be fixed in the receiving hole through the injection of an adhesive fluid (9; 209) at least in the portion of hole (11; 211) cored in the foundation (2)
Implementation Method 2
An intermediate filling material (4) is then injected, which results interposed between the foundation (2) and the platform (3)

AI summary
An assembly (1) for the realization of a railway comprising: - A foundation (2) formed by a casting on site, preferably in concrete; - At least one platform (3) arranged over the foundation (2) and; - Connection means to connect the platform (3) to the foundation ( 2 ). The connection means include at least one hole (11, 12; 211, 212) passing through the entire thickness of the platform (2) and penetrating at least in part into the underlying foundation.. Into the hole a pivot element (7, 8; 207, 208) results inserted, configured in such a way as to realize a connection between the foundation and the platform overhanging the foundation.
