Vibration Mechanism for Cable Laying in Sealed Soil
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for laying cables and lines in sealed soil layers, such as asphalt or concrete, often result in incomplete compression of the base layer, leading to cavities and reduced load-bearing capacity, which can cause frost damage and subsequent repair costs.
Innovation Solution
A device with a rotatable milling wheel and adjustable feeding system that creates a V-shaped furrow in sealed soil layers, equipped with a vibration mechanism to enhance material compression and prevent cavities, while allowing for easy cable or line installation and material separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional compression devices are used to compress the base layer under sealed soil layers, then the compression process can be performed, but the compression is insufficient and cavities form, reducing load-bearing capacity
Solution Approach 1:
The patent applies a vibration device that generates vertical vibrations during the compression process. These vibrations facilitate better penetration of the compression device into the base layer and improve the compaction of the backfilled material, eliminating cavities and ensuring uniform compression throughout the trench area, thereby maintaining load-bearing capacity under sealed soil layers
2Ease of operation
If trenches are created under paved, stony, or sealed soil layers using conventional methods, then the trench can be opened, but the soil or frost protection layer slips under the sealed layer, creating cavities
Solution Approach 1:
The vibration device operates during both the trench creation and backfilling processes. During trench creation, it prevents soil displacement and slipping under sealed layers. During backfilling, it ensures proper compaction of the frost protection layer and base layer, preventing cavity formation and maintaining structural stability of the sealed soil layer
3Ease of manufacture
If milling wheels are used to create trenches in sealed soil layers, then the trench can be formed, but cables are often damaged by pointed and sharp-edged rock in the floor
Solution Approach 1:
The vibration device operates during the trench creation process before cable installation. This preliminary vibration treatment loosens and redistributes the milled material, removing pointed and sharp-edged rocks from the trench floor and creating a smoother surface, thereby preventing cable damage during subsequent cable laying operations
4Productivity
If the base layer under sealed soil layer is not properly compressed, then the laying process is faster, but cavities form and frost damage occurs, requiring costly repairs
Solution Approach 1:
The vibration device ensures proper compression of the base layer and frost protection layer during the backfilling process. By applying vibrations, the device achieves thorough compaction that prevents cavity formation and ensures adequate frost protection, eliminating the need for costly repairs while maintaining efficient laying speeds
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device ensures proper compression of the base layer, maintaining load-bearing capacity and preventing cavities, thereby reducing the risk of frost damage and extending the service life of the material.
Implementation Method 1
Another advanced embodiment is characterized by the fact that the laying device can be trained with at least one vibration device. The vibration device vibrates the laying device in vibration, which means that the penetration of the surface can be carried out more easily and thus faster. The vibration device can also be advantageous in that the vibration of the laying device achieves a particularly high material compression and thus reduces the occurrence of cavities.
