Flexible Pipe Transfer Support for Stable Pipe-in-Pipe Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipe-in-pipe methods face challenges in stabilizing the posture of flexible pipes during transfer within existing pipelines, leading to potential deformation and inefficiencies in construction.
Innovation Solution
A pipe transport device with a rod-shaped pipe support that penetrates the pipe and is detachably supported by transporters, allowing stable transfer and easy detachment for efficient positioning and removal, along with adjustable projection portions to support couplings and reduce deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the connecting pipe is pulled by a wire from the winding device, then the pipe can be transferred into the existing pipeline, but the pipe may come into contact with the inner wall and become deformed
Solution Approach 1:
A pipe support is introduced as an intermediary device between the pipe and the pulling wire. The pipe support penetrates through the pipe and provides internal stabilization, preventing the pipe from contacting the pipeline inner wall during transfer while allowing efficient pulling operations
Solution Approach 2:
The pipe support is inserted inside the pipe, creating a nested structure where the support penetrates through the pipe wall. This internal support structure stabilizes the pipe from within during the transfer process, preventing deformation while maintaining transfer efficiency
2Reliability
If the pipe support penetrates the pipe to stabilize posture, then contact with the pipeline inner wall is prevented, but the support structure becomes more complex
Solution Approach 1:
The pipe support is divided into multiple segments or sections that can be independently positioned along the pipe length. Each segment can be adjusted to provide support at specific locations, reducing overall structural complexity while maintaining posture stability
Solution Approach 2:
The pipe support structure incorporates adjustable and movable components that can adapt to different pipe configurations and positions. This dynamic capability allows the support to maintain effectiveness without requiring a complex fixed structure

AI summary
A pipe transport device that transports a pipe to be installed in an existing pipeline includes a pipe support that is a rod-shaped structure and penetrates the flexible pipe to support the pipe, and pipe transporters detachably supporting the pipe support and configured to transfer the supported pipe support. The pipe transporters are configured to transfer, in the existing pipeline, the pipe supported by the pipe support along an axial direction of the pipeline, in a state where the pipe transporters support the pipe support.
