Our branch in Meißen is currently implementing a challenging project in the field of flood protection: The right flood protection dike on the Schwarze Elster has too high permeability due to its high organic content and storage density and therefore needs to be fundamentally renewed.
Overview of the work:
- Topsoil removal and processing: approx. 11,000 m³
- Removal of the old dike: around 130,000 m³
- Processing of excavated soil: approx. 95,000 m³
- New dike support body: approx. 87,000 m³
- Drainage layer: approx. 11,500 m³
- Base area: approx. 53,000 m²
- Construction of a 4 km long bike path on the dike crown
- Demolition of two bridges, DN 2200 pressure pipes, and a weir facility
- Construction of a gauge house (masonry construction, precast concrete parts, measuring section, paved gauge shaft)
- Replacement plantings: approx. 4,400 shrubs and plants
This is how the new dike is created
The material of the existing dike is removed and processed using a drum sieve to remove foreign components. It is then mixed with bentonite powder, installed in layers, and compacted. The final contour of the dike is precisely created using state-of-the-art GPS-controlled technology.
In addition to the dike renovation, old facilities of the Lusatian and Central German Mining Administration Company are being dismantled. A new gauge house with measuring section is being built for the State Operating Company for Environment and Agriculture. A bike path approximately four kilometers long is also being constructed on the dike crown – a noticeable added value for the region.
With this measure, SWIETELSKY makes an important contribution to the permanent securing of flood protection and at the same time strengthens the regional infrastructure.
