Hyperloop Tube Assembly on Girder Loops for Rough Terrain
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for constructing hyperloop transportation structures face challenges such as the difficulty in transporting large tube segments over rough or inaccessible terrain, and the complexity of ensuring energy supply and obtaining necessary electrical certifications during construction.
Innovation Solution
A method involving the creation of a substructure composed of piers and girders that form a circulation loop, allowing vehicles to transport and position tube segments along two parallel pathways, thereby simplifying the assembly process and accommodating challenging terrains.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If tube segments are transported to construction site by vehicles on ground, then assembly is possible, but transportation becomes difficult on rough or inaccessible terrain
Solution Approach 1:
The invention transitions from ground-based transportation to aerial transportation by constructing a temporary girder framework above the ground. Vehicles travel along these girders to transport tube segments to the construction site, eliminating the need for ground access roads and making the system adaptable to rough or inaccessible terrain.
Solution Approach 2:
The transportation system is divided into modular components: piers, girders, and vehicles. The girder framework is constructed in segments that can be assembled incrementally, allowing the system to be built step-by-step along the route without requiring complete ground access.
2Productivity
If a single transportation pathway is used for conveying tube segments, then vehicle routing is simple, but construction efficiency decreases due to waiting time
Solution Approach 1:
The transportation system is divided into two separate pathways: an outbound pathway for conveying tube segments to the construction site and an inbound pathway for returning vehicles to the starting point. This segmentation allows simultaneous bidirectional traffic, eliminating waiting time and doubling construction efficiency.
Solution Approach 2:
The system dynamically assigns different pathways to different vehicle directions. Vehicles traveling outbound use one pathway while vehicles returning use the other, creating a dynamic traffic flow pattern that maximizes productivity without increasing overall system complexity.
