Drainage structure

from Wikipedia, the free encyclopedia

The drainage structure is a shaft in which a drainage ends. Technical components are gate valves, throttle devices and damming devices.

Drainage structures as components of retention soil filter systems have the following functions:

  • Control of the filter drain
  • Temporary blockage of the filter
  • Flow regulation by limiting the filter speed or the filter throughput
  • Avoidance of permanent backwater from the receiving water

A sampling option must be provided for the quality control of the process.

In the drainage area to the receiving water, the greatest possible physical re-ventilation of the throttle drain should be aimed for.
