Vibrator Cable Suspension for Deep Ground Penetration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vibrator arrangements for ground material compaction and column creation are limited by the overall height of the excavator, where only a small part of the total height can be utilized for penetration depth due to the constraints of the mast roller and roller head, restricting their application in construction near airports, under bridges, or near heavy-duty power lines.
Innovation Solution
A support device with a guide system that allows the vibrator arrangement to be held by two cables fastened on the pipe, with a guide device and deflection devices that enable the upper end of the pipe to be moved beyond the conventional limits, allowing the vibrator to penetrate deeper into the ground without additional external force, thus increasing the usable penetration depth while reducing the overall height of the setup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the vibrator arrangement is held on a cable guided over a roller head fastened at the upper end of the vibrator arrangement, then the vibrator arrangement can be supported and lowered into the ground, but the overall height of the excavator limits the penetration depth, with only a small part of the total height being utilized for useful penetration
Solution Approach 1:
The cable is routed through the interior hollow space of the vibrator arrangement pipe, allowing the cable to be nested within the pipe structure. This eliminates the need for external guide rollers and mast head rollers, enabling the vibrator arrangement to penetrate deeper into the ground without being limited by the excavator's overall height.
Solution Approach 2:
The cable guidance system is moved from an external horizontal arrangement (over the roller head at the upper end) to an internal vertical arrangement (through the hollow interior of the pipe). This dimensional repositioning allows the cable to pass through the pipe length, maximizing the usable penetration depth while minimizing the external height requirement.
2Ease of operation
If a roller head and mast head roller are used to guide the cable, then the cable can be properly directed, but these components occupy space that reduces the useful penetration depth from the total excavator height
Solution Approach 1:
The cable guidance function is extracted from the external roller head and mast head roller components and integrated directly into the vibrator arrangement pipe itself. The cable is fed through the hollow interior of the pipe, eliminating the need for separate external guidance components that would consume valuable height.
Solution Approach 2:
The hollow pipe of the vibrator arrangement serves multiple functions: it provides structural support, contains the vibrator mechanism, and simultaneously acts as a guide channel for the cable. This multi-functionality eliminates the need for separate cable guidance components.
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
This configuration allows for a greater penetration depth of the vibrator arrangement relative to the overall height, enabling effective material compaction and column creation in previously restricted areas with reduced overall height, making it suitable for construction near sensitive infrastructure.
Implementation Method 1
the vibrator arrangement is introduced with the silo pipe down to a desired depth into the ground whereby a column-like cavity is created which is initially filled up by the vibrator with the silo pipe
Implementation Method 2
The device comprises a vibrator arrangement with a pipe which has an upper end and a lower end and which has two cable holders which are arranged spaced from the upper end on the pipe, as well as each with a cable fastened on each cable holder
Implementation Method 3
A support device with a guide system that allows the vibrator arrangement to be held by two cables fastened on the pipe

AI summary
A device is provided for vibration compression or for producing cavities and/or material columns in the ground. The device comprises a vibrator with a pipe which has an upper end and a lower end and also two cable suspensions which are arranged on the pipe at a distance from the upper end. A cable is secured to each cable holder. A support device for the vibrator arrangement comprises a guide device on which the cables are guided in the longitudinal direction of the pipe between the cable holders and the upper end or above the upper end.
