DE3025360A1 - Underground agricultural irrigation system - uses horizontal perforated pipes from which water seeps into soil - Google Patents

Abstract

The irrigation system causes water to seep into the ground, using underground pipes (1-5) which are porous or not sealed together where they join. The water seeping into the earth rises to the surface by capillary action. The pipes are not laid with any fall, so that they do not act as drains, and seepage takes place from them over their whole length. They can be arranged to rise slightly at the ends, so that the water collects centrally and is there delivered into the earth. The pipes may be laid in loose ballast, the water first filling up the intervening spaces before reaching the earth.

Irrigation system using porous or non-binding pipes laid underground.

In contrast to drainage, the Sickage is suitable for feeding water into the ground and not sucking it off. The drainage pipes do not have a gradient, but run horizontally in the ground or form an arc that rises slightly at the pipe ends. The purpose of the drainage pipes is to allow the water that has been drawn into them to seep into the ground and must therefore be porous or must not be laid in a binding manner (this formulation is referred to as S-pipe in the following). So they work that sinking groundwater levels and are ideally suited to the drinking water reservoir in predominantly rural areas replenish and preserve. In contrast to the irrigation systems, which have a high degree of evaporation, here the water is directed directly into the soil and can only evaporate when it reaches the soil surface through the capillary action comes or has been ingested by the plants.

Sickage is therefore of great interest to arid areas around the world that are suffering from drought. She is also Of great interest to operators of lawns, especially golf courses, soccer fields and parks. As well as for tennis courts, to be used against the development of dust, whereby the tennis court can be played on continuously. In addition, for agricultural, horticultural and forestry areas and pastures. Most of the water remains in the ground impressive advantage.

1. A salinization of the earth's surface is avoided, at least the time was postponed because of large-scale surface evaporation not taking place.

2. It is possible to sow, cultivate and use the irrigated area in any form during irrigation.

3. The already sunk groundwater level is raised and thus the drinking water supply is ensured.

Sprinkling and flooding have a very close to the surface Effect and cannot be used as extensively.

The facility of the sickage

consists of a supply pipe, a ventilation shaft and from the S-pipe.

The ventilation shaft

can take on the function of a junction and is used to fill the S-pipes with water without congestion. By attaching With closures, the water supply from S-pipe to S-pipe can be regulated as required.

In order to achieve optimal infiltration, the S-pipe diameter must be be coordinated with the laying density. The laying depth, apart from the criteria mentioned above, depends on the use depending on the soil. Above all, it is important to ensure that the processing equipment does not damage the system. the The length of the S-pipes also depends on the criteria mentioned above. If the terrain is sloping, the S-pipes across the slope are an advantage.

The seepage can be prevented by laying the S-pipes in a gravel bed still to be increased.

The water supply can come from lakes, rivers, wells, cisterns, but also from sewage ditches. A silting up

To avoid the S-pipes, if necessary a clarification through a septic tank, which can contain several chambers, or an upstream connection of a cleaning filter is advisable.

The Sickage will replace the construction of complex reservoirs and supplement in the case of existence. It is thus an inevitably necessary link in environmental protection, the preservation guaranteed by vital growing areas of every plant genus.

Explanation of the drawings
Figure 1

shows S-pipes laid in the ground. The S-pipe marked with (1) is a pipe laid horizontally in the ground, which is in a Ballast bed (3) was laid. The S-pipe marked with (2) is curved with the pipe ends rising upwards laid pipe. Both S-pipes open into ventilation shafts (4). The shaft marked with (5) can also be used as a distributor. All ventilation shafts must be out protrude from the surface of the earth to guarantee trouble-free ventilation.

is a laying scheme. It shows feeding pipes (6) that are impermeable must be and can be laid both above and below the earth. It also shows a possible one Arrangement of the necessary S-pipes (1), (2), as well as distributors (5), ventilators (4) and connections (7). The connections (5) and distributors (7) can be equipped with regulators that regulate the water supply from the supply pipe (6). As a sticking out of the Ventilation shafts is unavoidable, it is useful to place them along roads (8), corridor boundaries, railway lines (8) and Because of embarrassed. The supply pipes shown here are derived from a water basin (9), but also a Lake, river, sewer, well or cistern.

Figure 3

shows how the Sickage works. The water is led into the S-Rohie (1) and (2), from which it is in the ground (10) or the gravel bed (3) seeps. The capillary action (11) brings the water to the soil surface and within reach of the Plants. Only here can the water evaporate.

is fed. For this purpose, a weir (14) is required that the Waste water passes into a septic tank (15) with several chambers (16). Here the water can check its chemical and biological purity examined while calming down and settling down at the same time. If necessary, it can also be done with chemical / biological Supplements are provided. It can also be treated mechanically here. This can be done by stirring or venting. The sludge that settles on the ground can be returned to the ground through composting. The weir is used also to divert the sewage past the septic tank if necessary, if it should carry pollutants with it. If the clarification in this system is not sufficient, a suction filter (17) is provided, which cleans the water again, before it is directed into the Sickage.
