A method and a means of removing sedimented particles in a fluid stream in a settlement basin (2). In the bottom of the settlement basin (2) there is a sluice (1) which may have a sluice gate (6). At the bottom of the settlement basin there is a longitudinal, flexible unit (4) which is shaped so that it can open or close the space between sluice (1) and the settlement basin (2). The unit (4) can move up or down the sluice (1) so that the space and thereby the point at which the sluice (1) attacks the settlement basin (2) can be at any point along the entire length of the sluice (1). |
