Underground Auxiliary Line Insertion Along Pipelines Without Soil Compaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for laying pipelines close to the surface, such as underground cables or lines, face challenges in achieving deep installation depths without significant soil compaction and surface disruption, particularly when introducing additional devices like ventilation lines, as they require larger devices that complicate the process and affect the soil structure.
Innovation Solution
A device with a housing and displacement element that allows for a completely underground laying method, featuring a guide and memory system to feed additional devices directly into the pipeline path, using a tubular element like a drilling device or pull head with adjustable connections for drill and protective pipes, and a displacement element like a sword or plow to create temporary openings without surface connection, ensuring minimal disruption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a blade and vehicle are used to install pipeline close to surface, then installation is achieved, but surface damage and soil compaction occur
Solution Approach 1:
The invention extracts the harmful interaction between the vehicle/blade and the soil surface by transitioning to a completely underground installation method. The pipeline is installed through boreholes created by drilling devices, eliminating the need for surface vehicles and blades, thus preventing surface damage and soil compaction while maintaining installation feasibility.
Solution Approach 2:
The invention introduces boreholes as an intermediary medium for pipeline installation. Instead of directly placing pipelines on the surface or through open trenches, the pipelines are guided through underground boreholes from starting points to destination points, allowing installation without surface disruption while achieving the same connectivity function.
2Length of stationary object
If greater installation depths are achieved with larger machines, then coverage above pipeline is improved, but soil compaction increases significantly
Solution Approach 1:
The invention replaces the mechanical system of large surface vehicles and blades with a drilling-based system. Drilling devices create boreholes through the soil without the need for heavy machinery operating on the surface, enabling deep installations while avoiding the soil compaction caused by large machines. The drilling process minimizes disturbance to the surrounding soil structure.
3Ease of manufacture
If additional devices are installed using open construction method, then installation is achieved, but surface disruption increases
Solution Approach 1:
The invention merges the installation of additional devices with the pipeline installation process itself. The additional devices are fed through the same boreholes and guiding structures used for pipeline installation, eliminating the need for separate surface operations. This combined approach achieves additional device installation without increasing surface disruption beyond what is already required for pipeline installation.
