Segmented Pipeline Support Apparatus for Trench Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pipeline installation methods require heavy equipment for lowering and welding pipelines, which is complex, time-consuming, and dangerous, and do not allow for efficient support within a trench.
Innovation Solution
A pipeline support apparatus with curved receiving sections and a removable pin mechanism that allows the pipeline to be safely and conveniently lowered into a trench, enabling welding and machining operations within the trench without the need for cranes or heavy equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If heavy equipment such as cranes is used to lower and support pipelines in the trench, then the pipeline can be safely lowered and supported, but the operation becomes complex, time-consuming, and dangerous
Solution Approach 1:
The support apparatus is divided into multiple sections that can be independently positioned and assembled within the trench. Each section provides localized support, eliminating the need for a single large crane operation. The segmented design allows for simpler, safer installation while maintaining reliable support throughout the pipeline length.
Solution Approach 2:
The support apparatus is designed to be self-positioning and self-supporting within the trench. Once installed, the apparatus autonomously supports the pipeline weight without requiring continuous operation of heavy equipment. The structure serves itself by distributing loads through its modular sections, eliminating the need for ongoing crane or heavy equipment intervention.
2Manufacturing precision
If heavy equipment is used for welding and machining operations on the pipeline, then proper welding can be achieved, but the operation becomes time-consuming and requires moving equipment repeatedly
Solution Approach 1:
The support apparatus is installed and positioned before welding operations begin. This preliminary setup creates stable, fixed work positions for pipeline sections, allowing welders to perform operations without waiting for equipment repositioning. The pre-established support structure enables continuous welding progress along the pipeline.
Solution Approach 2:
The support apparatus acts as an intermediary structure between the ground and the pipeline, providing stable platforms and access points for welding operations. This intermediate structure eliminates the need to move heavy equipment repeatedly, as the apparatus remains in place and facilitates all welding and machining activities throughout the installation process.
3Ease of operation
If the pipeline is lowered into the trench using conventional methods, then the pipeline can be installed, but heavy equipment must be moved to the trench location which is difficult and time-consuming
Solution Approach 1:
The support apparatus is divided into transportable sections that can be moved to the trench location more easily than conventional heavy equipment. These segmented components require minimal machinery for transport and can be rapidly assembled within the trench, significantly reducing the time and effort required compared to moving large cranes or lifting equipment to the site.
Solution Approach 2:
The support apparatus is designed as a temporary, easily deployable structure that serves its purpose during pipeline installation and then can be removed or left in place. Its simplified, less expensive construction allows for rapid deployment without requiring the movement of expensive, time-consuming heavy equipment, making the overall installation process more efficient.

AI summary
A support apparatus for installing a pipeline into a trench has a first pipeline-receiving section, a second pipeline-receiving section, and a fastener removably affixed to at least one of the first and second pipeline receiving sections. The fastener is connected to the first and second pipeline-receiving sections so as to be in a pipeline-supporting position. The fastener is removable from at least one of the first and second pipeline-receiving sections so as to allow the first and second pipeline-receiving sections to separate from each other. Each of the pipeline-receiving sections includes a pipeline-receiving surface and a support affixed to the pipeline-receiving surface and extending downwardly therefrom so as to allow the pipeline-receiving surface to be positioned at a desired location above a bottom of the trench.
