Abstract (en)
[origin: EP0358857A1] The invention relates to a drain manhole comprising a preferably corrugated pipe (1), in the wall of which openings are formed for connection to piping (36) and at the lower part of which a weight is disposed for increasing the stability. According to the invention, the weight takes the form of a ballast arrangement which is separated from the pipe (1) and can be attached to the latter. The said ballast arrangement may take the form of a chamber (3) which can be filled with liquid or bulkable solid ballast material and is formed on or can be attached to the underside of the pipe. The ballast material is preferably a bulk material and/or a liquid. Consequently, the time-consuming filling with concrete, which was necessary hitherto in the production of drain manholes, is eliminated and the transportation of the pipes is easier as they do not contain, as hitherto, a concrete weight from the very outset. <IMAGE>
