Pipeline Lining Element Post-Hardening Data Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for rehabilitating pipelines with resin-absorbing lining elements lack efficient documentation and data collection for the inversion, hardening, and pressing-on processes, making it difficult to accurately record and evaluate the rehabilitation process.
Innovation Solution
A method and system for applying and reading out information, such as QR codes or RFID chips, to the lining element after hardening, allowing for the storage and retrieval of data on the rehabilitation process, including physical parameters and evaluation protocols, using devices that can transmit data wirelessly or via cable to a surface-based data processing system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensors are integrated into the lining element during the rehabilitation process, then physical parameters (pressure, temperature) can be detected and evaluated, but the complexity of the rehabilitation device increases and the installation process becomes more difficult
Solution Approach 1:
Information parameters are applied to the lining element after hardening rather than during the rehabilitation process. This preliminary action separates the measurement function from the installation process, allowing the lining element to be installed using conventional methods without integrated sensors, thereby reducing device complexity while still enabling comprehensive documentation and evaluation of physical parameters through post-installation information application
2Loss of information
If information is applied to the lining element after hardening, then documentation of the rehabilitation process is improved, but an additional step in the process is required
Solution Approach 1:
The lining element itself serves as the information carrier, storing documentation of the rehabilitation process directly on its surface. This self-service approach eliminates the need for separate external documentation systems, allowing information to be applied and stored as part of the lining element's final state after hardening, thereby improving information retention without requiring complex external systems
3Productivity
If conventional rehabilitation methods are used without information application, then the installation process is simpler and faster, but comprehensive documentation and evaluation of the process is lost
Solution Approach 1:
Information about the rehabilitation process is copied onto the lining element in the form of information parameters (such as QR codes, barcodes, or other machine-readable formats). This copying mechanism allows comprehensive documentation to be stored on a compact, durable medium that can be applied to the lining element after hardening, preserving installation speed while enabling complete process documentation and evaluation

AI summary
A method for the rehabilitation of a pipeline with a lining element made of a resin-absorbing material, comprising the following steps: Impregnating the lining element with a hardenable resin; inserting the lining element into the pipeline and positioning the lining element at the pipeline section to be rehabilitated; pressing the lining element against the inner wall of the pipeline; hardening the lining element; and applying at least one information parameter to the lining element subsequent to its hardening.
