DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
This invention comprises a protective body/cover over water/air discharge openings on underground irrigation pipes.
DESCRIPTION OF THE RELATED TECHNOLOGY
Many experiments have been made with underground irrigation. In some cases a pipe is cut into desired lengths and opened with a longitudinal incision, thus enabling it to be pushed down over the pipe, covering the outlet opening and preventing it from being clogged with earth.
BRIEF DESCRIPTION OF THE DRAWING FIGURE
The FIGURE is a perspective view of the present invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
This system is effective with regard to watering, but problems have arisen with respect to the roots of some plants/trees which, when they grow and search for water, move towards the pipe and grow/penetrate in between the pipe and the covering pipe part which is used. The roots tear off the covering part and small roots grow in through the outlet openings on the pipe and block them.
In this invention known, attached pipe pieces and different types of known water reservoir boxes are replaced by placing on to the pipe a two-legged protective cover which is provided in such a manner that the upper part prevents earth from being moved into the outlet opening on the pipe. The lower part of the cover has foot plates, which prevent the pipe and cover from sinking down into the ground. Vertical walls are shaped or have projections which slope in towards the middle and convey the water from the pipe inwards, thus causing it to drip through air to the ground. The inside of the lower part of the protective cover will remain dry. This prevents the plants' roots from climbing up the walls in their search for water and blocking the water/air discharge holes on the supply pipes.
The invention can be implemented in several ways. In the attached drawings 1 illustrates an embodiment of a protective body/cover which is placed over the pipe 2. On the inside there are illustrated internal projections 3 which convey drips of water 4 through air 10 to the underlying earth 5. The lower part of the protective body/cover has outwardly facing plates/feets 6 which prevent the pipe from being pressed down into the ground 5. The protective body/cover is secured to the pipe by slots or holes 8 at the ends, into which a pin or plate 9 can be inserted in order to secure the cover 1 to the pipe.
1. A protective body cover (1) to be placed over underground pipes (2) having discharge openings for supplying aerated water (4) to soil, the cover comprising: legs (7) which extend downward, on either side of the pipe, to a distance from the upper curved part of approximately twice a diameter of the pipe, whereby an air pocket (10) is formed under the pipe; part of the pipe, a pair of projections (3) sloping inwardly and downwardly under the pipe, the projections conveying the water in drips through the air pocket to the soil approximately directly under the pipe; cover by support elements (9) disposed through slots or holes in the wall on either side of the pipe.
2. The body cover according to claim 1, a foot plate (6) on a lower part of at least one of the vertical legs, the foot plate standing outwardly therefrom approximately at right angles.
