ABSTRACT:
An arrangement in a gully for draining water to prevent accumulation of snow and ice therein includes a substantially cup-shaped gully member, having a lower outlet socket for connection to a waste pipe and an upper circumferential support flange; and a clamping ring secured on the upper end of the gully member. A circular vertical flange on the clamping ring receives and guides an upper crown-shaped grate resting on the clamping ring and having an upper central opening. A bore through the wall of the cup-shaped member is supplied with heated air from a hot air pipe mounted in the bore in such a manner that the mouth of its free end opens into the gully member. A float valve controls the mouth of the hot air pipe, which is designed for adjustable dispersion of the airstream from the pipe mouth below the grate.
