Description

Groundwater artificial recharge method of ditch type by considering geological properties

The present invention relates to a drainage-type groundwater artificial cultivation method using geological characteristics, which utilizes a drainage channel of a hydroponic cultivation area, and uses the geological characteristics of a target area to artificially cultivate the groundwater used.

In general, cultivation of crops such as vegetables, fruit trees, and flowers in facilities such as vinyl houses and glass greenhouses (hereinafter referred to as 'houses') is called facility cultivation, and facility cultivation artificially creates the most suitable environment for crop growth. It is well known that crops far superior to the mainland are produced and shipped in a short period of time, so that they can be maximized profits and can be grown year-round.

However, in winter plant cultivation, maintaining the temperature necessary for crops is the most important. As the oil price rises, the burden of heating costs increases, which causes a problem that affects the entire plant cultivation. In order to solve the problem of the heating cost as described above, the water film cultivation method using the ground water to increase the temperature in the house by spraying the ground water to maintain the temperature of about 15 ℃ outside the house in winter in recent years.

However, the conventional water film cultivation method using the groundwater is used as the groundwater is discarded through the waterway, etc., the groundwater level is lowered or exhausted due to the excessive amount of groundwater over long periods of use. There is a problem that the depth of the groundwater hole should be formed deeply.

In order to solve this problem, the conventional groundwater artificial cultivation method using an infiltration type facility is used. The representative groundwater cultivation method is an infiltration well method and a surface cultivation method using a well method. (surface spreading method), and other infiltration methods, groundwater reclamation by underground dams, groundwater reclamation by rice fields, and groundwater reclamation by forests.

In addition, in step S300, the trench 20 is characterized in that the depth is different according to the geological characteristics of the water film cultivation target area (S).

In addition, the stepper 300 in the step S300 is characterized in that the lower limit to the depth that can be raised to the water film medium on the ground through the pump means.

In addition, the water film cultivation target area (S) by at least one drainage path 10 having the trench 20 is connected to each other to form a network, artificial groundwater cultivation throughout the water film cultivation target area (S) This is characterized in that it becomes possible.

In addition, in the step S300, the drainage passage 10 is characterized in that the outlet 11 is formed in a position close to the ground, so that the drainage passage 10 can temporarily serve as a reservoir.

Hereinafter, with reference to Figures 1 to 5 will be described in detail the drainage-type groundwater artificial cultivation method using the geological characteristics according to the preferred embodiment of the present invention.

1. Investigating the lipids in the meningoid target area (S) (step S100):

In the water film cultivation target area (S) where a plurality of water film cultivation houses (100) are installed to carry out water film cultivation, ground water is used, and then the used ground water flows to the drainage passage (10) and the outlet (11) of the drainage passage (10). It has a form to discharge to the outside through.

In the water film cultivation target area (S) to form a grid for the discharge of the used groundwater and form a drainage path 10 connected to each other network. That is, the existing drainage channels 10 are naturally spaced apart from each other at predetermined intervals and thus form a network.

Therefore, in the present invention, it is intended to utilize the existing drainage path 10 formed in the water film cultivation target area S, and the groundwater used in the water film cultivation used through the drainage path 10 as described above is re-cultured in the aquifer. And to be introduced.

To this end, firstly select the meningo target area (S) to be applied to the groundwater artificial cultivation method of the present invention, and in the selected meningo target area (S) to determine whether it has a lipid for more efficient groundwater cultivation Investigate what form the lipids have.

2. Identifying the area where the permeable lipids are distributed (step S200):

The depth of the existing drainage passage 10 in the water film cultivation target area S usually has a depth of less than 1 m, and in the basement of such depth, geology is generally composed of clay or silt. This is a lipid (impermeable layer L1) that is difficult to reflow into the lower aquifer when the groundwater used is reclaimed into the ground.

Thus, in the present invention, the lipids of the entire water film cultivation target area S are analyzed in step S100, and in the step S200, the analyzed lipids are examined, and lipids having a large permeable lipid made of sand or gravel are distributed. By checking the area (water permeable layer (L2)), it is to confirm in advance the area where the efficiency can be increased when artificially cultivated groundwater.

3. The step of digging 20 to the depth of the permeable lipid in the drainage path 10 in the area where the permeable lipid is present (step S300):

After examining and confirming a region having a high permeability lipid among the meningery target region S through the above-described step S200, a drainage path 10 installed in the region having such a high permeability lipid is shown in FIG. 2. Likewise, it is a step for the trench 20.

That is, assuming that the depth of the existing drainage passage 10 is 1m, the part where the drainage passage 10 is installed is an impermeable layer (L1) made of clay and silt among the aquifers because the air gap is small and the inflow of the groundwater is difficult. It is to dig (10) further a predetermined depth (ex: 5 ~ 7m) to the permeable layer (L2) in the aquifer layer made of sand, gravel and the like with large voids.

Of course, in the case of the drainage path 10, the depth is determined solely by reflecting the geological characteristics of the water film cultivation target area (S), the depth of the drainage path 10 for each of the water film cultivation target area (S), or the water film cultivation target area The depths may be different for each drainage channel 10 in (S). In addition, the depth of the trench 20 formed in the drainage path 10 is also the lower limit (maximum depth) that can raise the groundwater to the water film medium on the ground through the pump means (ex: motor pump, etc.). It is possible.

Since the above-mentioned drainage passage 10 has a trench 20 to the permeable layer, the groundwater after being used in the water film cultivation target area S flows along the drainage passage 10, and thus the portion of the trench 20 is formed. Cultivation (or inflow) into the aquifer through the formation of a wide range of artificial cultivation areas within the hydrofilm cultivation target area (S) through more efficient groundwater artificial cultivation (a large number of groundwater artificial cultivation zones (circled in FIG. 5, circle A). ) Is possible.

In addition, in the present invention, since the operation of the trench 20 in the drainage passage 10 as described above is formed in each of the drainage passages 10 of the region having a high permeability lipid among the hydrophobic target region S, the hydrophobic target region By allowing artificial cultivation of groundwater in a wide area within (S), along with a part of the drainage path 10, which is a trench 20 at the peak of the winter meningocation peak (Peak), the area for meningoculation (S) The groundwater level of the whole can be prevented from falling.

In addition, in the case of the drainage path 10 in the existing water film cultivation target area S to which the trench 20 is applied in the present invention, as shown in FIG. 4, an outlet 11 formed at an end of the drainage path 10 is shown. By forming so close to the surface not to be much lower than the surface where the water film cultivation is installed, so that the drainage path 10 can serve as a reservoir for storing the groundwater used for water film cultivation for a predetermined time, thereby, The groundwater discharged to the drainage passage 10 is not discharged directly through the discharge opening 11, but stays in the drainage passage 10 for a predetermined time so that the groundwater may slowly flow into the aquifer through the trench 20.

4. Filling the water permeable member 30 in the trench 20 area through the drainage path 10 (S400):

After the operation of the trench 20 in the corresponding drainage path 10 (drainage of the area where the permeable layer exists) through the above-described step S300, as shown in FIGS. 3 to 4, according to various embodiments of the user. By artificially filling the permeable member 30 (ex: coarse gravel, etc.) in the trench 20 region through the drainage channel 10, not only the permeability may be maintained but also the drainage channel 10 or the trench ( 20) It may have an effect to prevent the fall accident, such as the worker falls into the work area.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It is to be understood that various changes and modifications may be made without departing from the scope of the appended claims.
