Definitions
- the invention relates to a trained as a composite pipe, provided with water inlet openings seeping pipe.
- Drain pipes as they are primarily used for agricultural applications, have according to DIN 1187 slit-shaped water inlet openings between the wave crests of the composite pipe, the width of these water inlet openings is a maximum of 2.0 mm.
- Fig. 3 indicates for this purpose such a composite tube, which is formed from an inner tube 1 and a curved outer tube 2.
- the corrugated outer tube 2 has - in cross-section - wave crests 3, which are bounded by two mutually outwardly inclined flanks 4, 5 and a these flanks 4, 5 limiting annular cylindrical peripheral surface 6. Two adjacent wave crests 3 are welded to the two inner facing flanks 4, 5 connecting foot web 7 with the inner smooth inner tube 1.
- This region forms in each case a wave trough 8.
- a slot-like water inlet opening 9 is formed centrally between two adjacent wave crests 3 with a width a in the longitudinal direction of the tube.
- a as already mentioned, 0.8 mm ⁇ a ⁇ 1.4 mm applies.
- t b + c.
- Such pipes with wide slot-like water inlet openings can be readily formed as solid wall pipes. However, this is not possible for composite pipes with the usual composite pipe geometry.
- the invention is therefore the object of designed as a composite pipes seepage pipes in such a way that slot-shaped water inlet openings can be provided with a large slot width.
- the essence of the invention lies in the fact that deviating from the usual composite tube geometry, the distance of adjacent wave crests from each other is increased such that wider slot-like water inlet openings can be formed without the bond between outer tube and inner tube is destroyed.
- Claim 2 is an advantageous embodiment in the foot of the wave mountains again.
- the wave crests 3 have the same cross section as the wave crests 3 in the prior art Fig. 3 ie they also have the appropriate dimensions b and d.
- the water inlet openings 9 ' have a width a', wherein it also applies here that the water inlet openings 9 'are formed centrally in the footbridge 7'.
- f 'of the two not through the water inlet openings 9 'cut parts of the footbridge 7' applies: f ' > 2.0 mm. It is further f ' ⁇ a' / 2.
- t ⁇ t ' After all, the same applies here as for the composite pipes Fig. 3 in that they are in the range of DN 100 to DN 300.

Abstract
Description
Die Erfindung betrifft ein als Verbundrohr ausgebildetes, mit Wassereintrittsöffnungen versehenes Sickerrohr.The invention relates to a trained as a composite pipe, provided with water inlet openings seeping pipe.
Drainrohre, wie sie primär für landwirtschaftliche Anwendungen eingesetzt werden, weisen gemäß DIN 1187 schlitzförmige Wassereintrittsöffnungen zwischen den Wellenbergen des Verbundrohrs auf, wobei die Breite dieser Wassereintrittsöffnungen maximal 2,0 mm beträgt.Drain pipes, as they are primarily used for agricultural applications, have according to DIN 1187 slit-shaped water inlet openings between the wave crests of the composite pipe, the width of these water inlet openings is a maximum of 2.0 mm.
Soweit derartige Verbundrohre als Sickerrohre im Verkehrswegebau eingesetzt werden, liegen die üblichen Schlitzbreiten zwischen 0,8 und 1,4 mm. Bei der insoweit üblichen Geometrie von Verbundrohren, wie dies in
Die vorstehend geschilderten bekannten Verbundrohre sind für den Einsatz im Gleiskörper- und Tunnelbau nicht geeignet, da dort Wassereintrittsöffnungen mit einer Schlitzbreite von 2,5 bis 5,0 mm und auch darüber hinaus gefordert werden. Diese großen Schlitzbreiten dienen dem Zweck, eine Verockerung bzw. Versinterung des Rohres zu verhindern. Außerdem soll das Freispülen verschlossener Wassereintrittsöffnungen ermöglicht werden.The above-described known composite pipes are not suitable for use in track and tunnel construction, since there water inlet openings are required with a slot width of 2.5 to 5.0 mm and also beyond. These large slot widths serve the purpose of preventing a Verockerung or sintering of the tube. In addition, the flushing of sealed water inlet openings should be made possible.
Derartige Rohre mit breiten schlitzartigen Wassereintrittsöffnungen können ohne weiteres als Vollwandrohre ausgebildet werden. Für Verbundrohre mit der üblichen Verbundrohrgeometrie ist dies aber nicht möglich.Such pipes with wide slot-like water inlet openings can be readily formed as solid wall pipes. However, this is not possible for composite pipes with the usual composite pipe geometry.
Der Erfindung liegt daher die Aufgabe zugrunde, als Verbundrohre ausgebildete Sickerrohre so auszugestalten, dass auch schlitzförmige Wassereintrittsöffnungen mit großer Schlitzbreite vorgesehen werden können.The invention is therefore the object of designed as a composite pipes seepage pipes in such a way that slot-shaped water inlet openings can be provided with a large slot width.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Der Kern der Erfindung liegt darin, dass abweichend von der üblichen Verbundrohrgeometrie der Abstand benachbarter Wellenberge voneinander derart vergrößert ist, dass breitere schlitzartige Wassereintrittsöffnungen ausgebildet werden können, ohne dass der Verbund zwischen Außenrohr und Innenrohr zerstört wird.This object is achieved by the features of
Anspruch 2 gibt eine vorteilhafte Ausgestaltung im Fußbereich der Wellenberge wieder.
