Self-Supporting Railway Shoring System for Caisson Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for eliminating road and railway intersections through caisson insertion are hindered by the need for transverse supports and longitudinal shoring assemblies, which are time-consuming to install and disassemble, disrupting traffic and prolonging the process.
Innovation Solution
A self-supporting shoring system that eliminates the need for transverse supports above the caisson and reduces the complexity of longitudinal shoring, allowing for continuous railway traffic during assembly and disassembly, using metal shoring beams and perpendicular beams with a mechanical fixing system to maintain track elevation and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If transverse supports and longitudinal shoring assemblies are used to support the track during caisson insertion, then the track stability is ensured, but the installation and disassembly time increases, disrupting traffic
Solution Approach 1:
The invention extracts and eliminates the transverse supports from the shoring system, retaining only the longitudinal beams that run parallel to the track. This removal of unnecessary components reduces installation and disassembly time while maintaining track stability through the longitudinal beams alone, directly resolving the contradiction between stability and time loss.
Solution Approach 2:
The shoring system is segmented into independent longitudinal beams that can be installed and removed separately along the track. This segmentation allows for faster, more flexible installation and disassembly operations compared to the integrated transverse support system, reducing traffic disruption while maintaining structural stability.
2Stability of the object's composition
If traditional longitudinal shoring assemblies are used, then the track is supported during caisson insertion, but the complexity of assembly and disassembly increases
Solution Approach 1:
The invention extracts and removes the complex transverse support components from the shoring system, leaving only the essential longitudinal beams. This simplification reduces the number of parts that need to be assembled and disassembled, directly addressing the contradiction between providing track support and reducing system complexity.
3Stability of the object's composition
If transverse supports are installed above the caisson, then the caisson is properly supported during insertion, but the duration of caisson insertion increases
Solution Approach 1:
The invention removes the transverse supports that would require installation above the moving caisson, eliminating the time-consuming assembly and disassembly operations. The longitudinal beams provide continuous support without interfering with the caisson's insertion path, directly resolving the contradiction between caisson support and insertion duration.
Solution Approach 2:
The longitudinal beams are installed in advance parallel to the track before caisson insertion begins, positioned to provide support without requiring subsequent assembly during the insertion process. This preliminary positioning eliminates time-critical assembly operations during caisson insertion, addressing the contradiction between support provision and insertion speed.

AI summary
Supporting arrangement intended to be arranged in a shoring zone of railway lines (17), where at least first longitudinal metal beams (12) are arranged parallel to a line of the track on the outer side of each track line (17) so that they are braced by at least one second perpendicular metal beam (14) with a length less than that of the first longitudinal beams (12) and the joining of each longitudinal beam (12) to one end of the perpendicular beam (14) is performed by means of a mechanical fixing means (15).
