Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The current installation process for pipelines is time-consuming, resource-intensive, and prone to human errors, with inadequate soil support leading to premature pipeline failure due to uneven settlement and abrasion from sharp objects like rocks.
Innovation Solution
An automated system for installing a flexible fabric mat with a honeycomb structure filled with a settable material, which provides stable support, protects against sharp objects, and accelerates the installation process by dispensing and hardening in situ, creating a homogeneous surface for pipeline laying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional manual installation process is used for pipelines, then installation can be performed with simple equipment, but the process is time-consuming and consumes excessive resources such as water and manpower
Solution Approach 1:
The flexible fabric mat is designed to be self-installing through its unique properties. The mat automatically conforms to the trench contours and provides self-leveling capability, eliminating the need for extensive manual trench preparation and reducing dependency on specialized installation equipment and personnel.
Solution Approach 2:
The patent changes the physical state and properties of the support material from rigid to flexible. The flexible fabric mat can transition from a compact rolled state during transport to an expanded state in the trench, adapting to various terrain conditions and eliminating the need for precise trench dimensional control.
2Ease of manufacture
If rigid composite pipelines are installed without adequate soil support, then installation is simpler, but the pipeline becomes prone to premature failure due to uneven settlement and axial stress
Solution Approach 1:
The patent employs a flexible fabric mat as a thin film structure that wraps around and supports the rigid composite pipeline. This flexible mat conforms to the pipeline contours and provides uniform support, preventing uneven settlement and axial stress while maintaining installation simplicity.
Solution Approach 2:
The solution uses a composite system combining the rigid composite pipeline with a flexible fabric mat. This composite structure leverages the strength of the rigid pipe and the adaptability of the flexible mat, creating a more reliable installation that prevents premature failure while keeping the installation process straightforward.
3Device complexity
If traditional installation methods are used without protective mat, then the process is less complex, but sharp objects like rocks cause abrasion and lead to pipeline failure
Solution Approach 1:
The flexible fabric mat is installed beforehand to create a protective cushion between sharp objects in the trench and the composite pipeline. This pre-installed protective layer prevents abrasion and mechanical damage during and after installation, eliminating the need for extensive trench cleaning to remove all sharp objects.
Solution Approach 2:
The flexible fabric mat serves as an intermediary layer between the harsh trench environment (containing sharp rocks and objects) and the composite pipeline. This mediator protects the pipeline from direct contact with harmful elements while adding minimal complexity to the installation process.
4Reliability
If detailed trenching and soil preparation are performed to ensure proper support, then pipeline support is improved, but the installation time and resource consumption increase significantly
Solution Approach 1:
The flexible fabric mat performs self-leveling and self-adjustment functions that would otherwise require detailed trench preparation. The mat automatically conforms to the trench bottom contours and distributes loads evenly, providing reliable soil support without the need for time-consuming manual trenching and soil grading operations.
