Definitions
- the present invention also provides a kit of parts, as claimed in claim 20, for forming the irrigation apparatus of claim 1.
- the present invention further, provides a method of use, as claimed in claim 23, of the irrigation apparatus of claim 1.
- the present invention provides apparatus with a conduit which can be rolled up into a compact roll for easy transportation.
- the conduit can also be easily cut to a desired length by an installer.
- Figure 3 is a view of a part of the apparatus of Figure 1, showing a lower part of the reservoir and the two ends of the conduit fixed in place in the lower part of the reservoir;
- Figure 4 shows a part of the apparatus of Figure 1 comprising the reservoir and two ends of the conduit;
- Figure 13 shows an adapter for use with the irrigation apparatus of Figures 1 to 12a, allowing the easy connection of the irrigation apparatus to a hose to receive a pressurised supply of water;
- Figure 17 illustrates a cross-section through a third alternative conduit suitable for the Figure 1 apparatus
- the conduit 14 is a wick drain.
- a prefabricated core 15 of high quality flexible polypropylene having preformed grooves or water channels 16 on both sides of a central substrate 17.
- the substrate 17 is a central sheet which has ribs formed on both sides thereof, the ribs running lengthwise along the core, the ribs defining the water channels 16 which run along the length of the conduit.
- the core 17 is tightly wrapped in a geotextile filter jacket 18 of spun bonded polypropylene, which has very high water permeability while resisting flow thereacross of the finest of soil particles. Both the core 17 and the geotextile filter jacket 18 have high mechanical strength and are also durable in situ in the earth.
- This compression ensures a good watertight seal between the two parts of the reservoir and between the edges of the slits in the lower part of the reservoir and the conduit lying therebetween.
- the annular lower edge of the upper part could be tapered to ease the sliding of the upper part over the lower part .
- the reservoir 13 is shown having a bottom spike 40 which will extend below the bottom surface of the pit to fix the reservoir in position, but this is not essential and the reservoir could be formed without a spike and simply placed on the root ball, on the pit bottom or on earth filled in the pit at a point when the rootball has been located in the pit and the pit partially filled.
- the reservoir will be buried in a way which leaves the top surface of the reservoir 13 exposed when the pit is fully filled with topsoil and/or fertiliser to bed the mature or semi -mature tree 10 in place.
- the irrigation apparatus shown in Figure 1 has only one reservoir 13, but variants could be constructed with two reservoirs, e.g. for use with larger trees, as shown in Figure 6.
- two reservoirs 60 and 61 are shown connected by two wick drain conduits 62 and 63.
- One end of the conduit 62 will extend through slots in the reservoir 60 and the other end of the conduit 62 will extend through slots in the reservoir 61.
- one end of the conduit 63 will extend through slots in the reservoir 60 and the other end of the conduit 63 will extend through slots in the reservoir 61. Water can then be added to both reservoirs 60 and 61 to flow through the conduits 62 and 63 to irrigate a plant or tree.
- FIG. 17 or a core 100 with trapezium shaped elements as illustrated in Figure 10, surrounded by a jacket 101.
- the corrugated sheet providing core 100 has grooves 102 which provide water channels running lengthwise along the conduit.
- the dimensions hi, h2 of Figures 2, 10 (being the largest dimensions of the cross-section of the core, the widths) will vary from product to product, to suit different watering requirements.
- One example is 50mm (approximately), another is 100mm (approximately) .
- the core when viewed in transverse cross-section (as shown in Figures 2 and 10) has a first dimension along a first axis (a "height", h x in Figure 2 and h 2 in Figure 10) which is at least ten times a second dimension along a second axis perpendicular to the first axis (a "width" , W 1 in Figure 2 and W 2 in Figure 10) . Consequently the core can bend more easily about the first axis (and axes parallel thereto) than the second axis (and axes parallel thereto) .
- a typical depth Wi, W 2 would be 3mm (approximately) .
- each reservoir Whilst above each reservoir is shown with an integral cap formed with a hole, for insertion of a hose, and flexible leaves, each reservoir could be formed with a separate cap.
- Figure 11a is a plan view of a bottom part 110 of an alternative reservoir for use with the figure 1 apparatus. The same component is shown in cross-section in figure lib. It has slots 111 and 112 for receiving the conduit ends. It has a flat base 113 (without a spike) . It is circular when viewed in plan and the upper edge is tapered. It is designed for use with a top part 120.
- An adapter 130 as illustrated in Figure 13 could be used with the reservoir 110.
- the adapter 130 comprises a fitting 131 over which an end of a hose can be slid, with a flexible elastomeric O-ring 132 providing a substantially watertight seal between the fitting 131 and the hose.
- the adapter 130 will form a substantially watertight seal with the reservoir 110 and thus will allow pressurisation of the water in the reservoir 110 and the wick drain connected thereto, the water being pressurised to a pressure approaching the supply pressure in the hose. This allows a rapid drenching of the rootball during irrigation, when the hose is attached in the system, by increasing the rate of water flow. Pressurisation also allows use of longer runs of wick drain material since the pressurised water will flow further along such runs before it is dispersed into the soil, than if gravity feed alone is used.
- a 6cm girth tree will typically require at least 30 litres of water per month and a semi- mature tree, with a girth of 20cm or more, will need 300 litres of water monthly.
- the present invention facilitates such watering and provides a targeted irrigation system that delivers water directly to the root zone.
- the water supplied to the reservoir runs out in two opposite directions from the reservoir all the way around the circumference of the rootball, drenching the soil laterally. There is minimal water waste, since the system avoids the run off and evaporation losses associated with watering the top of the exposed surface around the soil above the rootball, exposed to the air, because the system is buried. Also the large delivery surface provided by the porous geotexile material lessens the amount of water escaping directly into the bottom of the tree pit, such losses occurring typically with single point watering.
- the irrigation apparatus of the present invention is easy to assemble and can easily be tailored to size, by cutting the wick drain to a desired length.
- the use of the wick drain material (as opposed to traditional substantially rigid piping) allows a compact package for transport, significantly reducing transport costs.
- the irrigation apparatus of the present invention delivers not only water to the root systems of trees, but also advantageously delivers air directly to the tree roots.
- the use of wick drain prevents blockages.
- the irrigation apparatus of the present invention can be connected to an existing irrigation system as illustrated in Figures 18 and 19.
- Figure 18 illustrates a known irrigation system comprising perforated plastic tubing 180 laid in concentric circles about a tree, on top of the soil, in which the tree is planted.
- the tubing 180 is connected to a pressurised water supply.
- the supply of water can be controlled by a timer so that pressurised water is periodically supplied to the tree.
