When water is in the way
For the development of large construction areas and long cable and pipeline routes, groundwater lowering via horizontal dewatering is a very effective method. With our drainage machines, a milling depth of up to 7.80 m below the ground surface can be achieved. To allow groundwater inflow in soils that are difficult to drain, the drainage trench is filled with drainage sand via a gravel funnel.
Advantages:
- Safe working on the construction site due to construction freedom
- Reduced groundwater extraction quantities compared to vertical dewatering due to a two-dimensional lowering of the groundwater level
- Reduced impact on the environment due to a groundwater-friendly extraction method
- Savings in fuel and/or electricity consumption
Our systems of horizontal dewatering
Vacuum drainage
By connecting the drainage pipes directly to a vacuum piston pump, the groundwater is transported to the discharge point by means of negative pressure.
Gravity drainage
The installed drainage lines are connected to a collection manhole. The groundwater flows with a free fall to the collection shaft and is pumped from the collection shaft to the discharge point by means of a submersible pump.
