。An installation for underground irrigation of cultivated land is described in Swiss Patent Publication No. 611118, in which a device for discharging water onto the ground is shown. This type of land irrigation facility is suitable for areas where rainfall is low and water sources are not abundant or extremely difficult to access. This is because of the relatively low water consumption and low water pressure (about 1O-
This is because optimum moisture content can be maintained in the root zone of cultivated plants at 150 CrrL water column). Since the water supply is regulated and controllable in this case, such installations are also suitable for research purposes, for growing plant varieties, and for clearing barren or dry land.

ある。耕地への４湿のために区画状またはくし状に設計
された従来の池水管では、事情が鴫かに困難である。Experience has shown that the supply of water to the distribution point and its preparation at the distribution point presents no problems. This is because the parts of the equipment in question are relatively easily protected against dirt, lime deposits and root growth and can be easily maintained if necessary. The situation is particularly difficult with conventional pond water pipes designed in compartments or combs for the purpose of supplying moisture to cultivated land.

れないことは明らかである。In order to obtain as uniform a distribution of water as possible over the limited surface area of the cultivated area, openings are provided at predetermined intervals along the pipeline, and in order to prevent soil components and root growth from entering. It is known to cover this opening with a porous filter member. However, it is clear that even with the use of corrosion-resistant, relatively densely felted filter media, the desired protection against root growth is only partially achieved under severe conditions due to dirt and calcification.

、濾材で確実な遮蔽を得ることは難しい。It is also difficult to obtain reliable shielding with filter media since the environmental and service conditions are often harsh and attaching the filter media to the tubes poses great difficulties.

。SUMMARY OF THE INVENTION Therefore, the object of the present invention is to provide a method that can be manufactured at a relatively low cost, preferably continuously, and that effectively protects the water discharge section from dirt and roots entering the pipe without the need for supplementary attachment of filter media. It is an object of the present invention to provide an irrigation pipe for land irrigation equipment of the above-mentioned type. Still, it is to configure the irrigation pipes in such a way that a vertical alignment of the irrigation pipes is virtually unnecessary and the advantages of mechanical laying of the irrigation pipes can therefore be utilized optimally.

。When assembling the inner profile 61 and the cover profile 68, which is basically constructed as in Figure @5, care must be taken that both the inner profile and the cover profile have a continuous acid slit. The proper functioning of the sealing lip 67 is therefore dependent on the inner profile 6
1 and the cover profile 68 relative to each other and a predetermined pressing force of the end 70 of the cover profile 68.

７２も円形母線７６の内部にある。When extrusion molding a water pipe having the shape shown in FIG. 7, the upper circumferential wall 72 is first moved outwardly along the broken line 72', as explained in the section molding shown in FIGS. 1 to 4. Preform. Next, in a pre-diameter forming process, the upper peripheral wall portion 72 is formed into a clear cylindrical shape as shown by a solid line. In this case, both the circumferential wall 71 and the upper circumferential wall 72, which are designed as profile support structures, lie inside the circular generatrix 76.

に密接し密封対向面として働く。FIG. 8 shows a modified example of the construction of a curved water-specific profile carved out from the general outline and shape shown in FIG. 7. In the case of FIG. 8, an upper peripheral wall part 82 is connected in a counterclockwise direction at a height of the horizontal center plane 2-v to a lower peripheral wall part 81 in which the profile support structure is bent into a cylindrical shape. The lip portion 86 extends over the entire upper half of the upper circumferential wall 82r/i shape and a part of the lower half of the shape.
end with. The lip portion 83 closely contacts the outside of the vertical flat wall 84 and serves as a sealing opposing surface.

is recessed. The support member 86 is in the horizontal central plane V-V
with an abutment surface 86' substantially parallel to or slightly inclined with respect to the central plane of the sealing lip or rib 8.
5, the load (arrow P) on the upper wall portion 82 is absorbed. In this case, since the support structure also includes the support portion 86 protruding from the upper wall portion 82, the wall thicknesses of the lower and upper portions of the tube can be selected to be equal.

め釦、この区域を一緒に定径することができる。When extruding a curved water pipe having the shape shown in FIG. 8, the same procedure as for the profile shown in FIG. 7 is carried out. To avoid deleterious deformation of the support member 860 area when sizing the upper portion 82 from its preliminary shape according to dashed line 82' to its finished shape according to cylindrical generatrix 88, this area can be sized together.

勿論第１図〜第８図による輪郭、形状は本発明の範囲内

形材の上下整列を事実上不要にする。It is possible to rationally manufacture pipe profiles from non-corrosive, root-repelling plastic materials, such as polypropylene, polyethylene, PvC, in particular depending on the conditions of use and location, e.g. soil temperature, soil pressure due to harvesting machines. Materials must be selected according to compressive stress, mechanical and chemical properties of the land, water quality, fertilizer loading, etc. When transportation distances are long, it is also important to closely stack the iLt problem. The at least approximately cylindrical shape of the seawater pipe according to the invention greatly facilitates mechanical underground piping;
The arrangement of the sealing part or the water discharge part on the surface of the profile virtually eliminates the need for vertical alignment of the pipe profile.
