Storage space for liquids, with a flushing device

A storage space for liquids, comprising:

• a rain basin;
• at least one flushing chamber positioned at a maximum height of the bottom of said storage space and fillable with storage liquid;
• said flushing chamber emitting storage liquid in form of a torrent of flushing water through at least one flushing opening when said storage space empties;
• said flushing chamber filling automatically with storage liquid as the level of storage liquid rises;
• means for retaining storage liquid in said flushing chamber once said storage liquid has arrived in said flushing chamber;
• closure means controlled by the level of storage liquid in said storage space for closing and opening said flushing opening;
• said flushing chamber collecting a part of said liquid;
• said part of liquid being first released through said flushing opening when said storage space has emptied to enable flushing said storage space thoroughly with a strong torrent from the maximum height to the minimum height of the bottom of said storage space to remove sludge deposited in said storage space;
• means for closing off said flushing opening;
• float means in said storage space for actuating said means for closing off said flushing opening;
• a runoff area in said storage space, said float being in said runoff area and located dependent on the level of liquid in said storage space and liquid in said runoff area.

• intake means into said storage space;
• at least one choke positioned in vicinity of said intake means and between said intake means and said storage space;
• intake opening means communicating with said storage space;
• means for closing off said intake opening means and comprising a flap trap;
• means for closing off said flushing opening in said flushing chamber;
• float means in said storage space for actuating said means for closing off said flushing opening in said flushing chamber, said float means being located in a runoff area of said storage space and dependent on the level of liquid in said storage space and liquid in said runoff area;
• a vestibule and a first wall between said vestibule and said flushing chamber;
• a second wall between said flushing chamber and said storage space, said first wall and said second wall comprising an overflow sill;
• said storage space having runoff gutter means extending in a direction that the storage liquid flows out, and parallel structural sections at a side that channel said flushing torrent laterally;
• said flushing chamber being at the highest point of said gutter means and emptying into said gutter means;
• said storage space having transversely sloping bottom with additional channeling sections along the basin to channel the flushing torrent;
• said storage space having a base of predetermined geometrical shape.
