Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current deep soil mixing technologies are inefficient, wasteful, and costly due to high energy consumption, significant tool wear, and sensitivity to dense or stiff soils, leading to suboptimal soil conditioning and mixing results.
Innovation Solution
The use of soil mixing tools equipped with drilling tools, cutting wheels, and nozzles that inject industrial lubricating foam, polymers, anti-clay agents, and colloidal systems containing phyllosilicates, granulated blast furnace slag, or cement to condition and strengthen soil, reducing density and improving soil properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional deep soil mixing technologies are used, then soil mixing can be achieved, but energy consumption is high and tool wear is significant
Solution Approach 1:
A lubricating foam is introduced as an intermediary substance between the cutting tools and soil. This foam reduces friction and wear on the tools while also conditioning the soil, thereby resolving the contradiction between achieving effective soil mixing and minimizing tool wear and energy consumption
Solution Approach 2:
The physical and chemical parameters of the soil are changed by introducing the lubricating foam, which modifies soil density, viscosity, and friction characteristics. This parameter change enables more efficient mixing with reduced tool wear and lower energy requirements
2Adaptability or versatility
If conventional soil mixing methods are used, then mixing can be performed, but the methods are sensitive to dense or stiff soils and organics
Solution Approach 1:
The lubricating foam acts as a mediator that conditions the soil before mixing, making the mixing process less sensitive to soil type. It reduces the impact of dense, stiff soils and organics on mixing effectiveness, thereby improving adaptability while maintaining reliable mixing quality
Solution Approach 2:
The lubricating foam is applied preliminarily to the soil before the actual mixing operation. This preliminary conditioning prepares the soil by reducing its density and improving its workability, making subsequent mixing more effective regardless of soil type
3Productivity
If current deep mixing equipment is used, then soil mixing is achieved, but equipment requirements are large and heavy
Solution Approach 1:
The lubricating foam enables more efficient soil conditioning and mixing, which allows the use of lighter equipment. By reducing the friction and resistance during mixing, the system achieves high productivity with reduced equipment weight and smaller mobilization costs
