Abstract

Watering and ventilating device for woody plants having an inlet opening for air and water, characterized in that an inner pipe section (d) is arranged inside an outer pipe section (a), that the inner area of the inner pipe section (d) with the inner area of the outer pipe section ( a) is in the gas exchange and that the upper mouth of the inner pipe section (d) is formed as an inlet opening (g) for both air and water.

Description

The invention relates to an irrigation and ventilation device for woody plants with an inlet opening for air and water.

State of the art

The known devices are used for irrigation and ventilation in the replanting of trees and other woody plants.

The device is used for underground irrigation and ventilation of woody plants, especially trees in the urban area, where usually only a small tree slice for aboveground irrigation and aerating is present, which is usually not sufficient.

• a) Zur Trennung der Wasser- und Luftversorgung müssen vollkommen getrennte Systeme eingebaut werden. Das ist sehr kosten- und arbeitsaufwändig. Man hat mehrere sichtbare Öffnungen oder Abdeckkappen an der Oberfläche. Es besteht permanent Verwechslungsgefahr, d. h. es wird dann versehentlich im Belüftungssystem bewässert.
• b) Es werden Systeme eingebaut, die gleichzeitig zur Belüftung und Bewässerung dienen. Bewässerung sollte, vor allem in den ersten Jahren, in den oberen Schichten erfolgen, Belüftung muss vor allem in tieferen Bereichen erfolgen. Bewässerungsrohre verschlämmen auf die Dauer, dann ist langfristig keine gute Belüftung mehr gewährleistet. Außerdem ist nach den Fachnormen der FLL ein Bewässern in Belüftungssysteme nicht zulässig.

• c) Herkömmliche Systeme verfügen über keinen Schmutzfilter.

Such devices are known, but have a number of Mach parts, which are mentioned below.

• a) To separate the water and air supply completely separate systems must be installed. This is very cost and labor intensive. There are several visible openings or caps on the surface. There is a constant risk of confusion, ie it is then irrigated by mistake in the ventilation system.
• b) Systems are installed which simultaneously serve for ventilation and irrigation. Irrigation should be done in the upper strata, especially in the early years. Ventilation must be carried out mainly in deeper areas. Irrigation pipes sludge in the long run, then long-term good ventilation is no longer guaranteed. In addition, according to the technical standards of the FLL, irrigation in ventilation systems is not permitted.

• c) Conventional systems do not have a dirt filter.

Task and solution of the invention

Object of the invention: According to the invention, the o. G. Disadvantages are avoided.

This object is achieved in an irrigation and ventilation device for woody plants of the type mentioned in the present invention that an inner pipe section (d) within an outer pipe section (a) is arranged, that the inner region of the inner pipe section (d) with the inner region of the outer Pipe section (a) is in the gas exchange and that the upper mouth of the inner pipe section (d) as an inlet opening (g) is formed for both air and water.

Advantageous embodiments of the invention are set forth in the subclaims.

According to the invention, separate underground pipes for water and air are provided in trenches with a common connection and an automatic separation of water and air in the area of the connection.

The irrigation and ventilation are carried out according to the invention via a single filler neck. The water then flows directly into a separate line. Permanent ventilation is ensured via the other line.

The installation height and the circumference of the irrigation and ventilation pipes can be flexible in both horizontal and vertical orientation.

The protection against unwanted dirt entry is ensured by a filter.

embodiment

In the following an embodiment of the invention will be described in more detail with reference to drawings. In all drawings, like reference numerals have the same meaning and therefore may be explained only once.

In the 1 and 2 exemplary embodiments of the innovation are shown by way of example. 1 shows a side view and 2 a plan schematic.

The irrigation and ventilation combination consists of a pipe (a) with a sleeve (b) at the top. In the lower part of the tube is an opening (c), in which a thinner rectangular bent kinked pipe (d) is glued or welded.

The thinner tube is guided vertically upwards in the thicker tube to the neck of the sleeve. In the upper area, the thinner pipe is provided with holes (e) all around, allowing the air to enter the thicker pipe. In the sleeve, a cover plate (f) is embedded and glued or welded, which rests flush on the thinner tube and is connected thereto.

In the cover plate there is a larger opening (g), about which once the air exchange takes place and on the other hand, the water is supplied. The opening in the cover plate is slightly smaller than the diameter of the thinner tube, thereby the water supplied during a casting process remains in the thinner tube and is distributed over it. On the cover plate, a filter (i) of various kinds can be installed to prevent dirt entering the system.

The lateral outlet of the thinner tube may, for. B. with a tee (h) are provided to achieve two outlets. On the outlet or the outlets of the thinner pipe usually commercial drainage pipes (j) are inserted in the desired length for irrigation. On the lower opening of the tube (a) a perforated tube (k) is inserted for ventilation, which usually leads vertically downwards in the desired length, but can also be performed via tees in different horizontal directions. The sleeve (g) can be raised at will with a rigid or flexible tube ( 1 ), which also controls the depth of the lateral outlet.
