Description
IRRIGATION CONSTRUCTION WITH CAPILLARY PIPES
The present invention generally relates to an artificial irrigation apparatus of the type comprising a water magazine in the form of one or more interconnected liquid containers, one or more interconnecting liquid tubes or corresponding means, which are buried into the ground or in the flower bed, and which is/are arranged both to emit water and air (oxygen) to the earth above and aside of the water magazine and to allow a draining of excess water from the ground or the flower bed. The apparatus can be formed as a single liquid container, but it is preferably formed as a series of liquid containers or liquid tubes which are formed as separate units, and which are interconnected by means of tubes or hoses, especially useful for filling up several liquid containers from one single place.
There are systems, in which the water is distributed to the earth above the liquid container through a tank lid which is perforated; there are other systems, in which the water is soaked up and is distributed to the earth above the liquid container by means of wicks of different types. All the prior known systems are disadvantageous in certain respects, for instance in that : they give out too much water when the water containers are full and too little water when the water level in the water container is low, they provide a bad oxygen supply to the earth above the water containers, the wicks become blocked by small particles of the earth, so that they, in time, give out too little water, - that roots from the plants above the container penetrate into the water container or into the water soaking wick and stop of the water emitting,
that roots from "sick" plants, which penetrate into the water container, poison the water and spread the sickness to other plants which are supplied with water from the same water system.
An artificial irrigation system of the said type is known for instance from GB 2.194.123, which system is composed of several liquid emitting bowls which are open at the top and which enclose a foam material and a water conduit arranged underneath the water emitting bowls and from which water conduit water is soaked up into the foam material and further on into the earth above the liquid emitting foam material. A similar apparatus is known from SE 444.379, which apparatus comprises partly closed containers which are filled with a water soaking substrate which can be supplied with liquid by liquid nozzles arranged inside the water soaking substrate, and which can emit liquid to the earth above and adjacent the containers through openings in the upper side of the containers .
Both above mentioned artificial irrigation apparatus make it possible to spread water into the earth above and aside of the liquid emitting means, and in certain cases they allow a draining of excess water from the ground above the liquid containers. Both apparatus, however, are disadvantageous in that the roots of the plants may penetrate into the liquid emitting foam material or substrate, respectively, and as far as to the water system or the water emitting means, respectively. If there should appear a disease, for instance harmful bacteria in a plant there is a risk that said disease is spread via the water to other plants by root contact of the plant with the water, in the worst case perhaps to all plants belonging to the same water system. There is also a risk that the water emitting substrate, into which the roots
of the plants may have penetrated, lets through bacteria from sick plants and lead same down into the water system when draining excess water from the earth above the containers . In both said known apparatus it may also happen that the water is spread so that the earth closest to the water emitting substrate gets a concentration of moisture whereas the earth above the substrate gets a successively less moisture, and that plants having short roots thereby get a deficit of moisture, whereas plants having deeply located roots get an excess of moisture.
The above mentioned prior known apparatus also are formed so that they emit only water to the earth closest to the liquid containers. It is, however, important for the growth of the plants that the roots thereof also get a supply of oxygen, and this is not possible in the said prior known apparatus.
Said problem is partly solved by a further known artificial irrigation apparatus which is known from SE 423.022, and which is formed as a water container having a perforated top and one or more hollow feet projecting downwards through said top, with the lower part of the feet dipped down in the water in the container, and which feet are adapted to be filled with earth or another material which soaks up and distributes water to the earth above and adjacent the water container. Said container is formed with a perforated top which can provide both draining of excess moisture in the earth and supply of air/oxygen to the earth above the container. The said container solves the problem in the previously mentioned apparatus as concerns supply of oxygen, but it is disadvantageous in that the roots of the plants may penetrate down through the perforated top and reach as far as to the water in the container and can thereby spread sicknesses from one plant to all plants connected to the irrigation system.
There is also a risk that the earth above the perforated top, and the roots moving down through the perforations fall down and that they choke/block the perforations thereby preventing a draining of excess water and a supply upwards of air/oxygen to the earth above the water container.
The basis of the invention therefore has been the problem or providing an artificial irrigation apparatus, which provides an even distribution of moisture even to an essential height over the water magazine, - which prevents a penetration downwards of roots into the water, which provides an aeration/oxygenation of the earth above and aside of the water container, which allows a draining of excess water without the risk of contamination of the water in the water magazine, which prevents a blocking of the openings in the water emitting means.
The said problems and lacks in the previously known artificial irrigation systems are solved by means of an apparatus comprising one or more closed water containers adapted to contain a certain amount of water, having or not having fertilisers or other preparations.
According to the invention the closed water containers are formed with two different means extending through the top of the containers, and which
a) are both of a porous material, for instance a foam plastic of foam rubber material, a porous ceramic material etc. having a very large number of small pores of capillary type, in particular micro pores,
b) one means of which is a water emitting means in the form
of a bar or a porous material which extends from a place at or close to the bottom of the water container and a distance up into the earth above the water container, for instance to a level of 10-30 centimetres under the root system of the plant,
c) the second means of which likewise is of a porous material and extends from a place above the water level in the water container and a slight distance up into the earth above the water container, for instance 5-50 centimetres.
The first means, a water distributor, gives a good distribution of water. By capillary action it soaks up water with nearly constant capacity to a substantial height above the water container and with an even water soaking effect independently of the height of the water level in the water container. The pores, which are of micro pore type, are so narrow, and above all so many, that they do not become choked by small particles in the earth and they make a choking/blocking by roots from plants above the water container impossible; they prevent a noticeable penetration of roots into the foam material of the water distributor.
The second means, an air cushion or air distributor, has a double function, namely both to emit air from the air space above the water level of the container and thereby aerate (oxygenize) the earth above the water container, and also to soak up and let down excess water into the water container in case the earth happens to be too damp.
The system preferably is formed with several water containers which are linked together by means of pieces of tubes or hoses, and the water distributors and the air cushions are arranged at suitable places in the water containers, for
instance one of them in each second container.
The invention is illustrated in the accompanying drawings, in which figure 1 diagrammatically and in a perspective view shows a number of interconnected water containers formed with water distributors and air cushions, and figure 2 shows a vertical cross sectional view through two interconnected water containers .
In figure 1 is shown a system of four water containers 1 which are connected to each other by means of pieces of tubes or hoses 2. The ends 3 and 4 of the outermost containers are closed. For filling of the containers with water, and eventually also fertilisers and/or disinfectants, there is a filling tube 5 which extends to a level above the ground surface. The water is distributed to all interconnected water containers 1 by the connection tubes 2, which are preferably mounted a slight distance underneath the top of the water containers .
The water containers 1 can be made as tubes having sealed ends with the possibility of taking up bores for the connection tubes, and they can be mounted in endless lengths comprising mutually interconnected water containers whereby the first and the last container is formed with closed and sealed ends. When laying the system at sloping areas it is foreseen that the containers are placed horizontally, whereas the connection tubes or hoses can be mounted obliquely and can be bent as desired.
Both the sides and the bottom and top of the water containers 1 are closed and sealed, but the top can be formed with one or more through bores for water distributors 6 and for air cushions 7. The water distributors 6 and the air cushions 7
can be of the same material and should be of a porous material having very narrow interconnecting, open capillary pores providing a great soaking capacity. The pores of the water distributors 6 and also of the air cushions 7 should be so narrow that they generally make penetration of roots into the pores and blocking by means of sand or earth particles impossible. They also should have such cross-sectional dimensions that water in the water container is soaked up as far as to the top of the water distributor 6 and gives an even and substantially unitary water distribution over the entire height of the water distributor 6. It is important that the pores of the water distributors 6 are open and communicate with each other, and that the pores thereby can be considered as a very large number of narrow vertical tubes which are interconnected to form an integral unit. The porous material of the water distributors 6 and the air cushions 7 can be a soft plastic material which swells in a liquid, it can be a burned granulate of a plastic material which is combined by any known inert binder, a ceramic material having communicating pores, a volcanic material, saw dust which has been burned to a carbon powder that has been combined in a porous unit, or granulates of another material that has been combined in a unit .
Both the water distributor 6 and the air cushion 7 are arranged to form a good sealing against the bore in the top of the water container 1 into which it is introduced. It is thereby an advantage that the porous material becomes swollen slightly at the contact with water thereby guaranteeing a good seal against the edges of the connection bore. Where the porous bodies are made of a "hard" material like a ceramic material, a volcanic material, a moulded hard plastic material etc., said bodies can be slightly conically tapering
in the direction downwards, so that the body can be pressed into a good sealing contact against the bore edges.
As best evident from figure 2 the water distributor 6 is arranged so as to extend inside the water container 1 to a level close to the bottom thereof. The water container 1 preferably is buried with the top thereof at a certain distance underneath the root system of the plant material, preferably so that the water distributor 6 with the top thereof becomes located at a distance of 10-30 centimetres underneath the root system of the plant material.
The air cushion 7 has to be placed with the bottom edge thereof above the water level, and it should extend to a distance above the top of the water container 1 of 5-50 centimetres. Decisive for the height extension of the air cushion is the planting depth, the quality of the earth and the type of plant material .
The object of the air cushion 7 is both to emit air/oxygen to the earth above and aside of the water magazine thereby oxygenizing the roots of the plants, and also to balance the moisture of the earth by soaking up and returning excess liquid to the water magazine.
As mentioned above the water distributor provides a substantially even and unitary water distribution, so that the earth above the water containers gets nearly the same moisture content of the entire depth down to the water container. The pores are so narrow that they prevent a penetration of roots into the porous material and a blocking/choking by plant roots, sand and earth. The air cushions 7, which can be of the same material as that of the water distributors 6, transmit the air above the water
surface of the water container 1 to the earth above the container thereby providing an aeration/oxygenizing of the earth.
