In the present application, terms such as "comprise" or "have" are intended to designate that the described feature, number, step, operation, component, part, or a combination thereof exists, but one or more other features or numbers , it is to be understood that it does not preclude the possibility of the existence or addition of steps, operations, components, parts, or combinations thereof.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings. The same reference numerals are used for the same components in the drawings, and repeated descriptions of the same components are omitted.

1, a structure 100 (hereinafter referred to as a 'structure') for forming a wet layer according to exemplary embodiments of the present invention is a dry layer 13 formed under the ground 11, And it is for application to the zone including the water-containing layer 17 containing water that can be used for plant cultivation under the dry layer 13 .

The water-containing layer 17 can be formed relatively deep from the ground 11, and in the case of a dry area, only a very small portion of water such as rainwater generated by rainfall, etc. permeates and does not evaporate and is formed by continuously watering. it could be

As described above, the water-containing layer 17 may be an area containing water that can be used for plant cultivation or the like.

The dry layer 13 is a zone that hardly contains water on the water-containing layer 17, and may be formed from the top of the water-containing layer 17 to the ground 11, but in the present invention, as in FIG. 11) Although the partial ground layer 15 is shown to be separated just below, the ground partial layer 15 will also be a zone included in the dry layer 13 .

As such, in the zone to which the structure 100 according to exemplary embodiments of the present invention is applied, a dry layer 13 that hardly contains water from the ground 11 to a predetermined depth below may be formed, and A water-containing layer 17 , which contains water to some extent, may be formed under the dry layer 13 .

The structure 100 according to exemplary embodiments of the present invention is a water rise for forming the dry layer 13 below the ground 11, in particular, the partial layer 15 below the ground as a wet layer 25 through which water permeates. A portion 19 may be provided.

The water riser 19 may be formed to extend to the partial layer 15 of the ground just below the ground 11, but in this case, even if the partial layer 15 of the ground 15 just below the ground 11 is converted into the wet layer 25 Since the state may not be maintained for a long time, in the present invention, the water rising part 19 may be formed up to the dry layer 13 just below the partial layer 15 of the ground rather than just below the ground 11 .

However, in the exemplary embodiments of the present invention, the water riser 19 may be provided to form a wet layer 25 up to the ground surface 11 including the ground partial layer 15 .

However, since the wet layer 25 formed on the ground 11 may not be able to maintain a wet state for a long time due to evaporation, the water rising part 19 that can be converted into the wet layer 25 is covered with soil or After forming the upper part of the water rising part 19 lower than the ground 11, it will be possible to suppress the evaporation of unnecessary moisture by covering the upper part with soil.

As mentioned, the water rising part 19 can raise water to the dry layer 13 under the partial layer 15 of the ground, which is just below the ground 11, among the water-containing layer 17 and the dry layer 13. It may be provided to connect between the water-containing layer 17 and the dry layer 13 under the partial layer 15 of the ground, or alternatively, the ground together with the dry layer 13 to raise the water to the ground 11 It may be provided to connect between the partial layer 15 and the ground surface 11 .

Accordingly, the structure 100 according to exemplary embodiments of the present invention includes the above-mentioned water rising part 19 from the water-containing layer 17 to the dry layer 13 below the ground partial layer 15 or the ground. By raising the water up to (11), the dry layer (13) in contact with the water rising part (19) may be converted into a wet layer (25) in which water permeates.

And in the following, a structure for raising water from the water-containing layer 17 to the dry layer 13 under the partial ground layer 15 will be described, but the present invention is not limited thereto.

That is, the structure 100 according to the exemplary embodiments of the present invention will be equally applicable to the structure for raising the water to the ground 11 in the above-mentioned structure.

In the water rising part 19, the water from the water-containing layer 17 to the dry layer 13 under the ground 11, in particular, the dry layer 13 under the partial layer 15 of the ground, by a diffusion phenomenon in addition to the capillary phenomenon. As what may be provided to be able to rise, it may be made to be provided with a connecting passage 21 and a filler 23 .

The connecting passage 21 for forming the water riser 19 is between the water-containing layer 17 and the dry layer 13 just below the ground 11, that is, the dry layer 13 under the partial layer 15 of the ground. It may be formed to have a hole structure that passes through, and the filler 23 for forming the water rising part 19 is formed to be filled in the connection passage 21 having a hole structure to generate a diffusion phenomenon together with a capillary phenomenon. can

For example, since the capillary filler 23 may have a fine tube structure, it may also be formed of a hollow fiber that is a hollow fiber.

When the filler 23 is made of hollow fibers, hollow fibers having an inner diameter of about 0.01 mm or less may be provided to have a bundle structure, and the length of the portion that absorbs water so that the water can permeate more efficiently is different from each other. will be able to provide

In addition, when the filler 23 has a fine tube structure such as a hollow fiber, the smaller the inner diameter of the tube, the more hydrophilic the hollow fiber material, the smaller the contact angle with water, the higher the capillary phenomenon will occur.

Accordingly, the structure 100 according to exemplary embodiments of the present invention will be able to determine the inner diameter of the hollow fiber made of the filler 23, the number of hollow fibers, etc. in consideration of the rising height of water, the rising amount of water, etc., In addition, it would be preferable to select a hydrophilic material with a small contact angle with water as the material of the hollow fiber.

As another example, the filler 23 may be provided to have a structure made of fine particles having water permeability, which is a property of allowing water to permeate, and/or hygroscopicity capable of absorbing water.

The fine particles mentioned are mainly particles having a size of about 0.1 mm or less, and may be made of natural or artificial materials such as silt, diatomaceous earth, ceramic, zeolite, perlite, expanded vermiculite, crushed plant stem, etc., and these are any one or two or more. It can be used by mixing.

In addition, when the capillary filler 23 is made of fine particles, the smaller the particle size and the smaller the void ratio, the higher the rising height of the water due to the capillary and diffusion phenomena.

Accordingly, the structure 100 according to exemplary embodiments of the present invention can determine the size, void ratio, material, etc. of the fine particles made of the filler 23 in consideration of the rising height of water and the rising amount of water. In addition, it will be possible to determine the material of the particle by referring to the properties according to the diffusion action.

As another example, the filler 23 may be provided to have a structure made of a porous material that can cause wetting and diffusion according to wetting.

The aforementioned porous materials have a pore size of about 0.05 mm or less and have a hydrophilic surface, and may be made of a natural or artificial material having porosity such as fibers, sponges, pulp, ceramics, and the like.

And when the filler 23 is made of porous materials, it may be provided to have a plate structure, a roll structure, a rod structure, and the like.

In addition, in the case of a porous material, as the pore size is small and the contact angle with water is small, capillary and diffusion phenomena may occur to a high height.

Accordingly, in the structure 100 according to exemplary embodiments of the present invention, the rising height of water, the rising amount of water, etc. may be obtained in consideration of the processing size of the porous material, the contact angle with water, and the like.

In this way, the structure 100 according to the exemplary embodiments of the present invention includes a water riser 19 to provide water impregnated in the water-containing layer 17 to the ground surface 11, a partial layer 15 below the ground. It will be possible to rise to the dry layer 13 below.

Therefore, the structure 100 according to the exemplary embodiments of the present invention permeates the dry layer 13 under the partial layer 15 of the ground, which is below the ground 11, without allowing the roots of plants to settle. The wetting layer 25 may be easily formed.

And the capillary filler 23 in the water riser 19 of the structure 100 according to exemplary embodiments of the present invention is not harmful to the environment because it is only necessary to form the wetting layer 25 for about the time the plant takes root. It would be more efficient to use a biodegradable material that can be decomposed after a certain period of time.

The water rising part 19 in the structure 100 according to the exemplary embodiments of the present invention is provided so that the filler 23 surrounds the periphery, and water can easily flow and permeate into the drying layer 13. It may further include a water-permeable film portion 27 made of a water-permeable material.

In this way, by using the water-permeable film portion 27 to surround the outer periphery of the filler 23 , the water rising from the water-containing layer 17 , the dry layer under the ground partial layer 15 below the ground surface 11 . (13) will permeate, and as a result, the dry layer (13) in contact with the water riser (19) may be converted into a wet layer (25) that is permeated with water.

And by using the water-permeable film portion 27 to surround the outer periphery of the capillary filler 23, the capillary filler 23 filled in the connection passage 21 may be formed to have a more robust structure.

In particular, when the capillary filler 23 is formed to have a porous material or a fine particle structure, the capillary filler 23 is not lost and can be more firmly supported by surrounding it with the aforementioned water-permeable film portion 27 .

However, since the structures in FIG. 2 are the same except for the water permeable film part among the structures in FIG. 1, the same reference numerals are used for the same members, and detailed descriptions thereof will be omitted.

Referring to FIG. 2 , the water rising part 19 in the structure 100 according to exemplary embodiments of the present invention is an impermeable film part 29 made of an impermeable material provided so that the capillary filler 23 surrounds the periphery. ) may be further included.

When the water permeable film part 27 is used as in FIG. 1 , all of the dry layers 13 in contact with the water rising part 19 may be formed of the wet layers 25 , but there is also a disadvantage that a lot of water may be consumed. Therefore, in FIG. 2, by using the water impermeable film part 29, only a part, not all, of the dry layer 13 in contact with the water rising part 19 is formed as the wet layer 25, thereby reducing the consumption of water and the wet layer ( 25) is formed in a more intensively limited area.

That is, in the case of the structure 100 in FIG. 2 , the wetting layer 25 is intensively limited to the area in which the water riser 19 and the ground 11 are in contact, in particular, the area in contact with the partial layer 15 of the ground is formed. You can do it.

And as in the structure 100 of FIG. 2 according to exemplary embodiments of the present invention, when the water rising part 19 is made to surround the capillary filler 23 using the impermeable film part 29, the water-containing layer ( The water-containing layer 17 to allow water to more easily permeate from 17) and to form the wet layer 25, which is converted into the dry layer 13, into an area that is more extended under the partial layer 15 of the ground. ) and the end in contact with the dry layer 13 under the partial layer of the ground 15, respectively, may be formed with a water-permeable film portion 31 made of a water-permeable material.

That is, the water-permeable film part 31 is used to surround the capillary filler 23 at the end contacting the water-containing layer 17 and the end contacting the dry layer 13 under the ground partial layer 15, respectively. In addition, it can be formed so as to surround the capillary filler 23 by using the impermeable film portion (29) other than that.

And in FIG. 2, the water-permeable film part 31 is used to surround the capillary filler 23, but although not shown otherwise, the end in contact with the water-containing layer 17 and the dry layer under the partial ground layer 15 It may be formed to have a structure in which the water-permeable film part 31 is provided at each of the ends in contact with (13), and the dry layer ( 13) may be formed to have a structure in which the water permeable film part 31 is filled in the hole structure by forming a hole structure at each end thereof.

However, in the present invention, although the water permeable film unit 31 in FIG. 2 and the water permeable film unit 27 in FIG. 1 are all marked with the same name because they have the same material as each other, the water permeable film unit in FIG. While the reference numeral 31 is partially formed in the capillary filler 23, the water-permeable film portion 27 in FIG. 1 has a structure formed entirely in the capillary filler 31, and thus is denoted by different symbols.

Referring to FIG. 3 , when water permeates from the water-containing layer 17 to the water riser 19 using the structure 100 according to exemplary embodiments of the present invention, at the end in contact with the water-containing layer 17 . Foreign substances may penetrate into the water rising part 19 of will be able

Accordingly, in the case of the structure 100 according to exemplary embodiments of the present invention, the water rising part 19 at the end in contact with the water-containing layer 17 has a filter that filters the penetration of foreign substances into the water rising part 19 . A portion 33 may be further formed.

In the case of the aforementioned filter part 33, it may be formed to have a water-permeable material because water has to pass smoothly and only to prevent the penetration of foreign substances, and it may be formed to have a structure surrounding the entire peripheral area including the end. will be.

In this way, the structure 100 according to the exemplary embodiments of the present invention forms the aforementioned filter part 33 to block the penetration of foreign substances, thereby more easily supplying water to the dry layer ( 13) can be raised.

Referring to FIG. 4 , in the case of the structure 100 according to exemplary embodiments of the present invention, a situation in which the wetting layer 25 is formed to be rather narrow may occur due to the rising amount of water.

Accordingly, in the case of the structure 100 according to exemplary embodiments of the present invention, the area of the wet layer 25 can be expanded to the peripheral area including the end in contact with the dry layer 13 under the partial layer 15 of the ground. An extension layer 41 may be further formed.

In the case of the aforementioned extension layer 41, it may be made of a material such as hygroscopic resin, silt, diatomaceous earth, perlite, plant stem, etc. capable of sufficient wetting of water.

As such, the structure according to exemplary embodiments of the present invention may secure the wet layer 25 converted from the dry layer 13 to have a wider area by forming the extension layer 41 .

The structure according to exemplary embodiments of the present invention may be more actively applied to dry areas where plant roots are difficult to establish.
