- the degradation of the soil with the inventive method is especially for the Lowering a caisson or Caissons in the by Soil removal produced well.
- the degradation of stable cohesive soils takes place in the Practice in mechanical degradation mode.
- Stable floors are particularly electro-hydraulic operated mining equipment or Aufrlochieri used.
- This known for stable floors process has the Disadvantage that the degradation performance compared to the degradation performance during the rinsing process for rolling floors only about 10%.
- Due to the pressure load is basically the permissible length of stay of the staff in the working chamber, in which the loosening and discharge of the soil, for health reasons limited to the compressed air regulation. Therefore, at the known method with high manual effort relative a lot of staff will be kept at the construction site.
- the Costs for lowering the caisson will be substantially determined by the factors personnel, equipment provisioning and Power consumption. A low lowering speed of Caissons is therefore equally important with relatively high Cost of the construction work.
