Definitions

  • the invention relates to a sewer structure, in particular a sewer shaft, with a liquid storage space arranged in it, which can be filled via an inlet and with its outlet interacts as a rinsing device, the process by Bottom or one side of the liquid storage space Building base emptied into the channel.
  • Such a channel structure is known from DE-U-9 016 513.
  • the drain empties through the floor of the liquid storage space to the building floor in the canal.
  • This is the Sewer structure specifically designed, with one in the sewer shaft integrated lifter, the legs of which at the lower end into one Siphon opens, which connects the jack to the channel. It deals is a corresponding to the specific application designed canal structure with flushing device, the considerable Construction costs for a new construction of the canal structure and otherwise retrofitting a canal structure with this Flushing device is not possible.
  • a sewer structure with flushing device of the type mentioned is also known from US-A 1,744,266.
  • This is operated via a linkage, which is an operating rod has a standpipe stored in the floor is guided and underneath the floor on a with water-filled trigger blade.
  • the bell swings from the floor and over the linkage takes off so that the liquid from the liquid storage space enters the channel.
  • the bell settles due to the emptied Release scoop on the ground again and it fills up Liquid storage space again.
