An arrangement with a drainage receptacle and a method of casting such a receptacle
or a bottom section for same |
(57) In an arrangement, in which a gutter receptacle (3) is connected to drainage collection
conduit (14,15) through a siphon trap (5,9), the new feature is that the part (9)
of the siphon trap lying outside the bottom section (5) of the receptacle (3) is a
part of a doubly-curved pipe (9,10), the downstream end (11) of which is connected
to the collecting pipes through a sliding muff (12).
The opening (7) is preferably cast by using a core or core ring (not shown) of a material
with low mechanical strength, such as hard cellular plastic, which remains in the
opening until the pipe (9,10) is to be installed. This provides in part for an accurate
casting of the opening (7), in part a protection of this opening during transport
and handling between the casting operation and the installation work.
