- allcons DSM Trencher (deep soil mixing) / Series TC
for building solid and water-blocking soil-cement walls in one pass by mixing the native soil with an injected cement suspension
Features
- Efficient alternative to conventional techniques for building cut-off walls, slurry walls or diaphragm walls
- Continuous applying of solid and dense soil-cement walls up to 25m deep and 1.25m wide without any soil movements
- Various performance classes available, from 300 up to 800m3/hr continuous rate
- Steel reinforcements can be used
- No sheet piling necessary
- According to European Standard EN 14679
- Deployed by the German railway company Deutsche Bahn AG
- The width of the soil-cement wall is unlimited by building several stripes next to each other
- The laterally shiftable boom allows the application three closely spaced walls without moving the guidance string line
