Monitor wells & control pumps automatically
The construction of the new S7 Fürstenfelder motorway brings Burgenland its first tunnel. From a geological point of view, the soil of clay, silt and sand poses a challenge. It is not possible to carry out blasting as is done with solid rock. Meter by meter, excavators are used to dig into the mountain and the tunnel is then sealed with shotcrete. In addition, the groundwater must be constantly monitored and pumped out to allow the tunnelling.
With the technology from Microtronics, cell GmbH and Elektrotechnik Mitterwallner have developed the autarchic well station “Fontano”. Each of the 103 wells along the Rudersdorf tunnel has a well pump, a level probe and a flow sensor installed. The networked control of the pumps automatically ensures that the groundwater level is lowered. All pumps and wells can be controlled remotely. In addition, the amount of water extracted is logged.
Should a pump fail, an alarm is immediately sent by SMS and e-mail. The tunnelling team is thus fast informed of the present damage and can secure the tunnel with shotcrete.
In the past, a pump attendant had to read the meter of all pumps in 24-hour intervals, but now the data is transmitted wirelessly to the central web platform. This enables automated monthly billing based on time and effort. The alarm system also ensures a fast kick off of the information chain in the event of an emergency.
