Abstract
A method of controlling the water level in ground in which drainage pipes have been laid, said method comprising: a) providing the ground with water passing through the drainage pipes in a natural way and/or by active intervention using a control system, b) creating an underpressure or overpressure of water and/or air in the drainage pipes by means of the control system, thereby causing water or air to be extracted from or supplied to the soil via the drainage pipes, and c) programming the programmable control system in such a manner that the control system determines the points in time, durations, volumes and/or order of the water supply to the drainage pipes and of the generation of an underpressure or overpressure of water and/or air.
Claims19
A device for controlling a water level in ground in which drainage pipes have been laid, the device comprising:
- a controllable water pump having a suction side connectable to a water reservoir and a pressure side connectable to drainage pipes in the ground;
- an additional controllable pump which is connectable to the drainage pipes configured to extract water and/or air from or pressing water and/or air into the drainage pipes;
- a programmable control system which is connected to each one of the controllable water pump and the additional controllable pump, the control system being configured to determine points in time, durations, volumes and/or order of the water supply to the drainage pipes and of the generation of an underpressure or overpressure of water or air in the drainage pipes;
- a buffer vessel connected to the drainage pipes, and the controllable water pump and the additional controllable pump are connected to said buffer vessel;
- and
- water level sensors and air pressure sensors provided in the buffer vessel and connected to the control system, the control system configured to control the controllable water pump and the additional controllable pump and influence the pressure condition in the buffer vessel based on the water level sensors and/or the air pressure sensors.

- a buffer vessel connected to the drainage pipes, and the controllable water pump and the additional controllable pump are connected to said buffer vessel;
- and
- wherein the additional controllable pump comprises an air pump which is connected to the buffer vessel and which is configured to press water and/or air from the buffer vessel into the drainage pipes or extract it therefrom by influencing the overpressure or underpressure of air in the buffer vessel.
