Definitions

  • the present invention relates to an arrangement of a drainage pipe provided with inlet holes for water.
  • the British specification GB-A-267.817 discloses a drainage pipe provided with perforations in its upper part and with a loose cover fitting over the perforations with a space between the pipe and the cover.
  • the lower portion of the cover is not on the same level as the bottom portion of the drainage pipe.
  • One drawback with said device is that there is not provided any sedimentation space and infiltrated water may therefore enter the drainage pipe. This is undesirable since the drainage water then must be further purified at the outlet of the drainage pipe. Further this prior art solution may yield a sedimentation within the pipe, thus causing gradual clogging of the pipe.
  • the present invention overcomes the above drawbacks and relates to an arrangement of a drainage pipe as defined in claim 1.
  • the exterior part is fixed to the drainage pipe by welding, adhesion or the like.
  • FIG 1 there is shown a drainage pipe 2 which in the figure is corrugated and provided with an array of inlet holes 3.
  • the drainage pipe is covered by an exterior plate 1 extending from base level over the top of the drainage pipe and partly down on the opposite side of the drainage pipe. Between the drainage pipe and the exterior plate there is in the longitudinal direction at the top arranged a sealing 4 between the drainage pipe and the plate. There is thus formed an inlet section for the water and an outlet section for the water consisting of the interior of the pipe 2.
  • the pipe 2 is corrugated.
  • Figure 3 shows an exterior plate 6 having supporting ribs 6', said supporting ribs being adapted in shape to the drainage pipe and facing said pipe. There is thus in this case formed two inlet sections, i.e. between the plate 6 and the drainage pipe on both sides of the drainage pipe.
  • the drainage pipe is illustrated to be corrugated, whereas the exterior plate has a smooth surface.
  • the drainage pipe may as well have a smooth surface and the exterior plate have a corrugated form, such as indicated in the embodiments of figures 6 and 7.
  • a drainage pipe 11 with a corrugated exterior plate 10.
  • the unit if figure 6 is placed on a filtering mat 9.
  • the filtering mat 9 has as its object to ensure effective filtering of the incoming water.
  • the exterior plate 12 is snapped over the drainage pipe 2.
  • the exterior plate is smooth and the pipe is corrugated, but this could of course be vice versa, or both elements being corrugated with different degree of corrugation.
  • the holes may be made substantially bigger than for common drainage pipes. Because the water to be drained rises slowly upwards before it reaches the holes, sand, soil, particles, etc. will be deposited and not enter into the drainage pipe. Another considerable advantage of the system consists in that the earth masses may be put back into the ditch over the drainage pipes after they with their covering plates or the like have been placed on common filtering bed, sand, gravel, sawdust or other material.
  • the arrangement according to figures 11 and 12 consists of two parts, where the first part is made from an internal pipe 13 with the said inlet openings 1 6 placed in the upper half of the pipe.
  • This pipe 13 thus forms the outlet section of the arrangement.
  • the other portion consists of a pipe or a jacket 14 surrounding the first part and having said openings in the lower half of the pipe or jacket.
  • said one array of openings may have the form of a slit arranged in the longitudinal direction of the jacket, such as in principle for the embodiment of figure 8.
  • the inner pipe 13 has a smooth surface
  • the outer pipe or jacket 14 has a corrugated surface, the outer limits of the corrugations being indicated by the reference numeral 15.
  • the first part 13 may have corrugated surface and the second part 14 have smoothed surface.
  • the jacket may possibly be snapped over the inner tube 13, such as indicated as an example in figure 8.
  • the first part may of course be pushed into the second part.
