Collecting Device for Soil Mixture Control in Foundation Drilling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing civil engineering methods for creating foundation elements in the ground often result in uncontrolled soil mixture emergence at the surface, leading to disposal or laborious return to the hole, which is resource-intensive and costly, especially in contaminated soil scenarios.
Innovation Solution
A collecting device is positioned above the hole to control and collect the soil mixture, forming a receiving chamber that surrounds the hole, allowing for efficient collection and return of the mixture, reducing uncontrolled drainage and transport costs through a design that includes adjustable walls and linkage devices for stabilization and volume adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If soil material is removed by drilling to create foundation elements, then the foundation element can be formed in-situ, but uncontrolled soil mixture emerges at the surface requiring disposal or laborious return to the hole
Solution Approach 1:
A collecting device with a receiving chamber is introduced as an intermediary component between the drilling system and the ground surface. This device collects the emerging soil mixture in a controlled manner and facilitates its return to the hole, eliminating the need for laborious manual operations while preventing uncontrolled disposal
Solution Approach 2:
The system is designed so that the soil mixture collected in the receiving chamber automatically flows back into the hole through gravity when the drilling device is retracted, reducing the need for additional energy input or complex mechanical systems for material return
2Productivity
If soil mixture emerges at the surface during drilling, then the hole can be cleared, but the emerging mass must be disposed of or laboriously returned to the bottom hole
Solution Approach 1:
The collecting device with receiving chamber is positioned and ready before drilling begins, allowing the soil mixture to be collected and returned during the drilling process itself rather than requiring separate post-drilling operations for material disposal or return
Solution Approach 2:
The collecting device serves as a mediator that streamlines the soil mixture management process, enabling continuous drilling operations without interruption for material disposal or return, thereby maintaining high productivity while eliminating time losses
3Loss of substance
If the collecting device surrounds the hole, then the removal device can be guided through and soil mixture can be collected, but the device complexity increases
Solution Approach 1:
The collecting device is segmented into a modular framework structure with multiple walls that can be assembled around the hole. This segmentation allows the device to be constructed from simple, standardized components rather than requiring a complex monolithic structure
Solution Approach 2:
The walls of the collecting device are designed as slender, wall-like structures that provide the necessary containment function with minimal material and structural complexity, allowing the device to surround the hole effectively while maintaining simplicity

Function Achieved in This Case
This solution enables a 10-40% reduction in soil mixture remaining on the surface, significantly reducing landfill costs and enhancing resource efficiency by allowing controlled collection and recycling of the soil mixture during the foundation element creation process.

AI summary
The invention relates to a civil engineering machine, a collection device for a civil engineering machine, and a method for creating a foundation element in the ground. The civil engineering machine comprises an excavation device for creating a hole in the ground by removing soil material, and the excavation device is vertically adjustable on a support structure of the civil engineering machine. The excavation device is designed to mix the removed soil material with an additive, which is fed into the hole by a feed device, to form a soil mixture within the hole. To collect soil material that emerges from the top of the hole, a collection device is provided, which is arranged at the top of the hole and at least partially surrounds it. A receiving chamber is formed by the collection device to receive the emerging soil material.
