Abstract (en)
A riser pipe with a floating gully covering comprising a covering rim (17) connected at a socket (12) to the riser pipe (10). There is provided on the outside of the riser pipe a circumferential spherically curved bulge (15) having the center of curvature on the center axis of the riser pipe, and there is provided on the inside of the socket an annular concavity adapted to the spherical curvature of the bulge, said concavity bearing against the bulge maintaining the riser pipe and the socket in mutual engagement allowing the gully covering to be universally tilted in relation to the riser pipe. According to the invention this concavity is formed by a strip element (19) provided between the socket (12) and the pipe (10) and consisting of plastics having good bearing properties, said element being received by an annular groove (17) in the inside cylindrical surface of ther socket. <IMAGE>
