A method of forming a land-based fish farm with one or more fish farming tanks (2), comprising the following steps in the method:
Description
Land-based fish farm
Preamble
The invention pertains to a method of forming a land-based fish farm with one or more fish farming tanks (2), where a substantial part of the method comprises diamond wire cutting of the at least cylindrical tank wall in fish farming tanks. The invention is also a suchlike land-based fish farm.
Background technique
Diamond wire cutting of rock is ideally utilized to cut out prismatic tunnels, where steel pipe linings are drilled in the prism tunnel’s longitudinal direction, and where the bottom, walls, and ceiling aperture are diamond cut out between pairs of steel casings, and where the cut out prism can be extracted by demolition without damaging roofs/ceilings, walls, and bottom in any substantial way.
It is known through background technique to drill a substantially circular pattern of bore holes in a rock wall in order to wire cut out apertures between paired bore holes in the circular pattern. However, this type of technology is chiefly tied to tunnel operations.
Fish farming tanks in water are usually manufactured out of steel or glass fiber and remain closed. Fish farming tanks on land are usually formed through concrete casting or steel welding. Water is pumped in through a water source, and following required cleaning, the water is released out through an outlet.
It is possible to form reservoirs outside in rock areas or in mountain halls through demolition, but a lot of post-demolition work will be required on these rocky surfaces in order to obtain a clean, smooth surface to facilitate farming volume, where it may be required to carry out adjusting demolition work, as well as concrete processing and afterwork, and often painting work to achieve a smooth, clean surface.
Brief summary of the invention
The invention is stated in the independent claims, with embodiments of the invention stated in the subordinating claims.
Brief figure explanation
The invention is illustrated in the enclosed figure illustrations.
Fig. 1 is a level outline of an embodiment of a fish farm according to the invention, which comprises an inlet manifold channel, here shown through three cylindrical fish farming tanks cut and formed through demolition work into the bedrock, and an outlet manifold channel. The upstream water inlet can be sourced from a fjord with a strong stream, and the return stream can occur downstream in the same fjord, because the pressure gradient can engage the water stream within the facility due to the generally smooth diamond wire cut walls in channels and tanks. Water cleaning and filtration may occur in or after the outlet manifold channel, and filtration may occur on its way in.
Fig. 2 is a longitudinal section through the tanks, the outlet channel, and inlet channel.
Fig. 3 is an enlarged outline of one of the tanks in Fig. 2, showing a slightly conical bottom formed through wire sawing prior to removal of mass.
Figs. 4, 5, 6, 7, 8, 9 and 10 illustrate vertical sections of steps in the method of forming a fish farming tank cut to fit into the bedrock, and where the mass has been removed through demolition following a cutting process. After sawing and demolition work, very little surface treatment is required apart from cleaning and removing any remaining sharp edges.
Fig. 11 is an illustration of a material water stream model according to the invention. In this model, the components are built in transparent plastic instead of being cut in the rock.
Description of embodiments of the invention
The invention provides a method of forming a land-based fish farm with one or more fish farming tanks (2), comprising the following steps in the method:
- diamond wire cutting in rock of a cylindrical aperture (20s) with diamond wire to the depth (d1) of the tank walls (20) in order to form a cylindrical aperture (20s), the outer surface of which shall constitute the fish farming tank’s (2) cylindrical tank wall (20),
- demolition work of parts or the whole of the rock volume within the aperture (20) in order to open the fish farming tank’s (2) tank volume within the cut tank wall (20),
- enabling the fish farming tank (2) to become substantially circularly cylindrical.
In one embodiment of the invention, the diamond wire cutting of the cylindrical aperture (20s) occurs in the drilling process and placement of a plurality of peripheral, vertical steel casings (23) at the tank wall’s desired depth (d1), and diamond wire cutting of vertical apertures (22s), see Fig. 4, along cords between paired adjacent steel casings up until the cylindrical aperture (20s) has been formed, see Figs. 5 and 6. You now have a cylindrical aperture (20s) of cut out apertures (22s) in the entirety of the diameter and the depth of the tank to be formed, and the volume remains as a massive rock plug, see Fig. 6.
Herein lies part of the ingenuity of it all: through the cutting out of the tank wall’s aperture (20s) from the bedrock, it will form an approx. 13 mm wide, mainly circularly cylindrical aperture in the rock, due to the diamond wire cut section.
The cylindrical aperture may comprise a plurality, e.g. 28, adjacent apertures formed along the cords which in all form a circle with a diameter of e.g. 40 meters. As such, one would be able, through demolition work, to form space for large parts of the tank volume within the cut aperture (22s), all he way out to the plane, smoothed section without the demolition work causing damage to the tank wall (20) since no cutting force from the impact is transferred over the section (which is substantially filled with water). One will as such achieve, through careful impact, a substantially smooth inner wall in the tank (20) with a low friction against the rotating water masses. You thus solve the problem regarding friction between the water stream and the rock wall in a mountain reservoir cut out by demolition work, and the reduced energy loss may contribute to the through stream of the whole fish farming tank may occur at the pressure gradient between the inlet (110) and the outlet (120). Fouling will thus become easier to counteract and remove due to the aforementioned smooth surface of the tank. This will all result in reduced manufacturing costs, reduced operational costs, reduced fouling, and may utilize sea water as a water source and tidal streams as an energy source for water replacement.
In one embodiment of the invention, the demolition work of the rock volume is carried out within the cylindrical aperture (20s) down to a first demolition depth (d2) less than the depth (d1) of the conical aperture (20s). At this point, a rough, demolished bottom surface is formed, see Fig. 7.
In a further embodiment, a conical bottom aperture (21s) is formed by the steps of:
- drilling of an amount of radial, slanted steel casings (29) from the center of the first demolished depth (d2) out to points at the bottom of the cylindrical remaining aperture (20s),
- diamond wire cutting of triangular apertures between paired steel casings (29) out to the bottom of the cylindrical remaining aperture (20s) for forming of a conical aperture (21s), see Fig. 7.
- demolition of the rock mass over the conical aperture (21s) until a conical bottom surface (21) remains, see Fig. 8.
A smooth bottom is formed through cutting of a conical bottom aperture (21s) and demolition work down to what shall become the conical bottom (21), both of which become smooth. Thus, the streaming resistance becomes minor in relation to a conventionally demolished rock wall, and the energy from the external stream gradient may be sufficient in order to drive the circulation of water to and from the tanks (2).
In one embodiment of the invention, a substantially tangential inlet channel (31) is drilled in through the tank wall (20) to the tank (2), and an outlet channel (32) from the tank (2).
In one embodiment of the invention, a prismatic longitudinal inlet manifold channel
(1) is diamond wire cut horizontally along a row of two or more tanks (1), from a feeding stream (110) from an upstream water inlet (0) to the inlet channels (31), and where a prismatic longitudinal outlet manifold channel (3) is diamond wire cut horizontally on the opposite side in relation to the inlet manifold channel (1) along a row of two or more tanks (1), for a return stream (120) of used water from the tanks
(2) to a downstream water outlet (4). It is easy to cut out prismatic reservoirs and channels, but in this case, the prismatic reservoir also provide access for the placing of a drilling machine for drilling of the tangential channels (31 , 32).
In one embodiment of the invention, the water inlet (0) for the feeding stream (110) is situated in a tidal stream (100), and the water outlet (4) for the return stream (120) is situated in a downstream part of the same tidal stream (100).
In one embodiment, the fish farming tank are formed in a manner where one levels and applies demolition work downwards, e.g. using diamond wire technique, to a surface level in the bedrock with a height H just above the surface level in the
adjacent tidal stream in the fjord outside, from the level in which one cuts and places in the cylindrical aperture in the rock formation. From this level H, one may also cut and place the supply manifold and the outlet manifold. As a result, the water level in the fish farming tanks with through streaming to and from the tidal stream externally be adjusted approximately corresponding with the height H below the top edge of the tanks. One may also observe the tidal effect from the inside of the tanks.
One will see a pressure gradient DR in the external stream (120) (enabling the streaming itself) and there will be the same pressure gradient between the feeding stream (110) and the return stream (120) driving the water circulation to and from the tanks (2). This tidal stream will thus remain active in the same direction just under six times, twice per 24-hour cycle. It is possible to exchange the inflow channels of the inlet manifold channel (1) and the outlet manifold channel (3) in order to exploit the tide in a reverse manner for the two other periods for the rest of the 24-hour cycle.
The invention also provides a land-based fish farm containing one or more fish farming tanks (2), comprising the following steps:
- the fish farming tank (2) being substantially circularly cylindrical,
- the fish farming tank’s (2) cylindrical tank wall (20) being cut out of rock formations by cutting down into an aperture (20s) with diamond wire to the depth (d1) of the tank wall (20),
- the at least parts of the tank volume of the fish farming tank (2) are substantially cut out on the inside of the cut tank wall (20). The construction provided is illustrated in Figs. 1 and 2.
In one embodiment of the invention, the bottom of the fish farming tank (2) is cut out as an aperture (20b) in a rock formation using diamond wire, after the aperture (20s) of the cylindrical tank wall has been cut out to a first depth (d1) in the rock formation.
In a further embodiment, the substantially circular tank wall (20) comprises a plurality of adjoining, adjacent, vertical section surfaces as apertures (22s) cut out along cords between evenly dispersed vertical, paired drilling holes (23) placed in the cylindrical circumference, to the depth (d1) in the rock formation, see Figs. 4, 5 and 6.
With favorable tidal differences, one may also exploit the tide by filling the inlet when streaming, while the outlet is closed, and open the outlet while the inlet is closed.
Through this process, a natural circulation is formed that runs for the entire 24-hour cycle.
