Abstract
Abstract of disclosure.
An arrangement relating to a drainage pipe provided with inlet holes for water, said holes being positioned on the upper half of the drainage pipe and the drainage pipe being fully or partly covered by a jacket or ex-terior plate. The lower edge or edges of the jacket lies or lie substantially on the same level as the lo-wer edge portion of the drainage pipe. The jacket may possibly be smooth, whereas the drainage pipe is corrugated. The water will then rise in the space bet-ween the jacket and the pipe, which space serves for deposition of possible particles, and thereafter will enter into the pipe through the holes. The arrangement may be used for simplified disposition of drainage without particular necessity for draining masses above the arrangement.

1.~. .
The prese~t invention relates to an arrangement of a drain-age pipe provided wi-th inlet holes for water.
It is common among drainage pipes that the inlet ~oles for water may be clogged, and the presen-t invention has an object by simple means to remedy this disadvantage.
According to the inven-tion the holes are positioned on the upper half of the drainage pipe, the ~rainage pipe being fully or partly covered by a jacket or ex-terior plate.
The present invention provides an arrangement of a drainage pipe and an exterior part, the drainage pipe being laid with its axis generally horizontal and being provided with inlet openings for water to be drained, said openings being in only a half, which in use will be the upper half, of the pipe, and the exterior part being located to cover but not close the openings of the drainage pipe at a distance from those parts of the drainage pipe where the openings are located, such that in use water may rise in the space be-tween the exterior part and pipe, wherein the exterior part extends downwards at least to a position which in use is at substantially the level of the lowermost portion of the drainage pipe, and wherein, in use, there is an inlet opening or openings from outside the arrangement into said space in the region oE said le-vel Df the lowermost portion.
Further characteristic features will appear from the at-tached claims and the following description with reference to the accompanying drawings.

Figure 10 shows an exterior pla-~e according to the invention for use with the arrangemen-t as shown in f,igure 3.
Fi,gure li shows a fiEth embodiment of the arrangement accor-ding -to the invention.
Figure 12 is a mod:Lfied embodiment of the arran~ement accor-ding to figure 11.
In figure 1 -there is shown a drainage pipe 2 which ln the figure is corrugated and provided wi-th 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 drainaye ' pipe and partly down on the opposi-te side of the drainage pipe. Between the drainage pipe and the exterior plate there is in the longitudinal direction a-t the -top arranged a sealing between the drainage pipe and the plate. There is thus formed an inle-t section for -the water and an outlet section for the water consisting of the in-terior of the pipe 2. In figure 2 there is shown a drainage pipe 2 with an array of inlet holes 3, where the drainage pipe is com-pletely covered by an ex-terior plate 5 placed on base level.
It will thereby immediately be seen that there,is :Eormed two inlet sections and one outle-t section consisting,of the in-terior of the pipe 2. In the example of figure 2 -the pipe
2 is corrugated.
Figure 3 shows an exterior plate 6 hav:i.ng ~upT?ortirlg rib~ 6', said supportiny rihs beiny adapted in shape to the arainage pipe and facing said pipe. There is thus in this case formed ,two inlet sections, i.e. between the plate 6 and the dxainage pipe on both sides of the drainage pipe.
In sirnilar manner there is in figures ~ and 5 arranged an ex-terior plate 7 with protruding legs 8 and in figure 5 there is in addition arranged a filtering mat 9 on which both the exterior pla~e and the drainage pipe are placed.
In the embodiments shown in figures 1 to 5, the drainage pipe ,, is illustrated to be corrugated, whereas the ex-terior pla-te ~3~
has a smoot:h surface. However, the cdrainage pipe may as well have a smoo-th surface and the exterior plate have a corruga-ted form, such as indica-ted in the embodiments of figures 6 and 7. In figure 6 there is shown a drainage pipe ll with a corruya-ted e~terior plate lO. In the embodiment of fiyure 7, the unit o:E figure 6 is placed on a filtering mat 9. The ~i]terincJ mat 9 has as its object to ensure effective filtering of the incoming water.
In figure 8, the exterior pla-te 12 is snapped over the drainage pipe 2. In the illustrated form, -the exterior plate is smoo-th and the pipe is corruga-ted, but this could of course be vice versa, or both elements being corruya-ted with different degree of corrugation.
In figures g and 10 there is shown as an example -the exterior plates used ln the embodimen-ts of figures 5 and 7 and figure

In figures g and 10 there is shown as an example -the exterior plates used ln the embodimen-ts of figures 5 and 7 and figure
3, respec-tively.
The holes may be made subs-tantially bigger than Eor common drainage pipes. Because the water -to be drained rises slowly upwards before it reaches the holes, sand, soil, par-ticles etc. will be deposited and not en-ter into the clrainage pipe.
~nother considerable advantage of the syste-m consists in that the earth masses may be put back into the clitch 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.
In figures ll and 12 there is indicated by arrows how the drainage water flows into an inlet section of the arrange-ment and down into a central outlet section of the arranye-ment.
The arrangement according to fiyures ll and 12 consists of two parts, where -the first part is made from an internal pipe 13 with the said inlet openings 16 placed in the upper half of the pipe. This pipe 13 thus forms the outlet section ., of the arrancJement. The o-ther portion consis-t of a pipe or 36~
a ~acke-t 14 surrounding the first par-t and having said openings in the lower half of the pipe or jacket. As will appear from figures 11 and 12, there may e.g. be one array of inlet ope-nings 17 or two arrays of inle-t openings in the lower half of the jacket, res~ec-tively. ~lternatively 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.
As shown in figures 11 and 12 the inner pipe 13 has a smooth surface, ~7hereas -the outer pipe or jacket 14 has a corrugated surface, the outer limits of -the corruga-tions being indicated by the reference numeral 15. Conversely the first part 13 may have corrugated surface and the second par,~t 14 have smoo-thed surface.
If there is used a jacket provided with said slit, the jacket may possibly be snapr,ed over the inner tube ]3, such as in-rlicated as an example in figure 8. Alterna-t:ively the first part may of course be pushed into the second part.
