Flotsam barrier Jirkov installed
The flotsam barrier Jirkov was completed in time for the fall and winter seasons.
The reservoir is located three kilometers northwest of Jirkov in the middle of forests on the southern slope of the Ore Mountains. The dam serves the drinking water supply of the North Bohemian Basin. In the reservoir there is an overflow shaft of 9.5 m in diameter.
The Jirkov dam is surrounded by steep, wooded mountainsides. As a result, flotsam gets repeatedly in the basin of the reservoir. The regulated flow of water and the operation of the hydroelectric power plant are thereby seriously endangered.
A particularly strong, flotsam barrier
Hydrotechnik Lübeck has developed a particularly strong, floating barrier for this requirement. It has a minimum breaking load of 380kN. With an expected service life of 12 years and permanent use, no further maintenance is necessary. The floating bodies of the barrier automatically adapt to the different water levels. It is mounted in such a way that drifting debris drives it to the shore with the help of natural currents. From there it can be taken out of the water.
In addition to this interesting task has also led the beautiful autumn weather for a good mood in the assembly team.
