Underground irrigation system

The invention relates to an underground irrigation system for cemetery facilities, private and public plantings with a container that can be inserted into the ground.

Today, seasonal plants are usually planted in the humus layer. During dry periods, the plants must be watered intensively - but damage still occurs. The plants often have to be replaced 2-3 times a year if they are to remain attractive.

The invention is based on the object of creating an underground irrigation system which can absorb, store and release moisture independently of a constant addition of water.

To solve this problem, the container must contain at least one layer of filling material for storing moisture and at least one layer of soil.

When installed correctly, the underground irrigation system provides the plants with enough water and long-term fertilizer so that even dry periods lasting several weeks can be survived without damage. As a rule, planting once is sufficient (April to the end of October).

The plants show excellent growth and damage from drought can generally be ruled out. The user no longer has to carry out the very time-consuming daily watering during dry periods.

In the simplest case, the irrigation system consists of a slightly conical plastic tub measuring approx. 700 x 700 x 250 mm (L., W., H.). These tubs can be lined up as desired. The tub is lined with a nonwoven fabric made of synthetic fibers (protects against contamination and creates a capillary effect). The liquid-absorbing granulate is poured onto the fleece to a height of approx. 150 mm. The nonwoven fabric is then covered over it, overlapping. The system is simply filled up via the filling pipe or when watering. A water level indicator indicates when the system is full or when it needs to be refilled.

The tub is provided with an overflow opening on all 4 sides. To prevent capillary action on the outside, which could inadvertently empty the vessel, the overflow is equipped with a so-called separating pipe. This separating pipe is covered on the inside and outside with gravel. The capacity of this construction is approx. 75 liters of granulate and approx. 50 liters of water. Rain or excess water runs off and cannot build up above the specified level. Waterlogging (moisture) is mechanically prevented.

The system is buried approximately 50 mm below the surface. It is then reinforced over the edge with

Filled with potting soil/grave soil (+ slow-release fertilizer) and water. It can then be planted as desired.

This invention can be installed in single and double graves, as well as in urn graves. The system can also be used in public and private gardens.

Further advantages, features and details of the invention will become apparent from the following description of preferred embodiments and from the drawing, which shows in

Fig. 1 is a schematic and perspective view of a grave site;

Fig. 2 is an exploded view of an underground irrigation system according to the present invention.

According to Fig. 1, a grave border 2 and a gravestone 3 are indicated by a grave site 1. Between the grave border 2 there are two irrigation systems 4.1 and 4.2 according to the invention.

Each irrigation system 4.1 or 4.2 has a container 5, which is preferably slightly conical in shape. In the container there is a layer 6 of filling material, onto which a layer of soil 7 is applied.

The filling material layer 6 consists of a liquid-absorbing granulate. This is poured onto a nonwoven fabric 8 and then another nonwoven fabric 9 is placed over it in an overlapping manner.

The container 5 has a plurality of overflows 10. For each overflow 10' a separating pipe 11 is provided, which is inserted into an overflow opening 12. Both inside the container 5 and outside the separating pipe 11 opens into a gravel bed 13 or 14.

Furthermore, a filling pipe 15 is inserted into the container 5 or the soil layer 7 and filling material layer 6, whereby a sieve 16 is located in the filling pipe 15.

Furthermore, a water level indicator 17 is also provided in the container 5.
