Definitions
- the invention relates to an intercepting sewer for conveying waste water down steep slopes.
- fall pits permits the inclination of a pipe line to be reduced, section by section, so as to bring the intercepting sewer to the desired depth whenever this latter would approach too much to a surface level.
- such an approach leads to significant final design costs and to difficulties in achieving the work, especially when it is to be carried out in a built-up area, since in this case in addition to depper digging operations involving added charges, there is special works to be taken into account in order to prevent neighbouring edifices from being damaged.
- the object of the invention is to provide a branch sewer which is so designed that - the flow rate and the slope being the same - it permits the flow velocity to be reduced without having recourse to any head pits and without requiring increased pipe diameter or other provisions which will affect economy of the work.
- the intercepting sewer, or sewer trunk line for conveying waste water down steep slopes is essentially caharacterized in that it has projections provided inside thereof.
- these projections are arranged circumferentially, are equidistant and are geometrically configurated so as to give rise to a generalized turbulence in the flow and to localized losses of head whereby any indesirable kinetik energy can be dissipated.
- the intercepting sewer in question has a maximum inside diameter of 37 cm and is provided with internal protrusions having a mean distance between the centers of 13.2 cm and a jutting-out thickness of 0.85 cm (thus, minimum diameter of intercepting-sewer at projectins, 35.3 cm and mean diameter, 36.15 cm), the intercepting sewer being laid at 10% slope.
