Wet soil mixing
Wet soil mixing
The wet soil mixing process takes place in following steps:
1. Positioning of mixing tool
2. Inserting the mixing tool under addition of binding agents
3. Mixing of the soil down to final depth
4. Rotary extraction of the mixing tool under addition of binding agents
5. Setting of the soil/binding agent mixture
For wet soil mixing the mixing tools rotate around the vertical axis of the mixing shaft. The tools break up the soil matrix and mix the suspension with the soil. The binding agents used are usually cement types mixed to a suspension by adding water.
Examples for wet soil mixing
Wet mixing with single or multiple mixing tool
Very frequently multiple mixing tools are used. Thus, panel shaped reinforced ground structures are produced.
Mixing drives as modular system
The mixing drives for uncased wet mixing can be modularly combined with each other.
Mixing tool for uncased wet mixing
The mixing tool consists of a hollow drilling linkage fitted with blades, knives or paddles at its lower end.
Introducing the suspension in the ground
The binding agent suspension is pressed into the soil through nozzles situated in the lower area of the mixing tool.
Producing a homogeneous soil mix column
The soil is further mixed during extraction of the mixing tool and further binding agent is injected.
