First Embodiment

1 is a flow chart illustrating a method of forming an environmentally friendly playground that is capable of storing and utilizing rainwater by permeation and evaporation according to the present invention, and FIG. 2 is a flowchart illustrating a method of manufacturing a cork chip according to the present invention. 4 is a cross-sectional view of a playground constructed by the method according to the first embodiment of the present invention, FIG. 4 is a cross-sectional view illustrating a rainwater inflow and storage method, and FIG. 5 is a cross-sectional view of a stored rainwater evaporation and discharge method.

As shown, the method of forming an environmentally friendly playground that is capable of storing and utilizing rainwater by permeation and evaporation according to the present invention, the work target ground 10 than the drainage channel 20 installed in the periphery of the work target ground 10 Starting from the lower composition step. When the ground 10 is formed to be lower than the drainage channel 20 as described above, a part of the side surface of the drainage passage 20 is exposed to the lower ground side. And the upper end of the drainage path 20 is provided with a steel grating 21 for preventing the fall and smooth inflow of rain water (step S10).

The drain hole 23 is formed at the side surface of the drainage channel 20 exposed as described above. The drain hole 23 is installed at a height spaced a predetermined height from the lower ground (10). This is to allow a certain amount of rainwater to be drained into the ground (10) lowered, and to exceed the rainwater is introduced into the drainage path (20) (step S20).

Thereafter, the waterproof sheet 30 is laminated on the ground 10 and the exposed drainage passage 20. At this time, the waterproof sheet 30 should be cut in a portion corresponding to the drain hole so as not to block the drain hole (23). If the waterproof sheet 30 is installed only to a position lower than the drain hole 23, the process of cutting the waterproof sheet 30 may be omitted (step S30).

Crushed stone is formed on the waterproof sheet 30 to form a permeable layer 40. And the formation thickness of the permeable layer 40 is enough to become more than the formation position of the said drain hole 23. Since the permeable layer 40 is formed of crushed stone, rainwater is freely introduced into the pores between the crushed stones and the stored rainwater can be evaporated through the pores (step S40).

The laid crushed stone is flattened and the crushed stone is solidified by sprinkling a binder on the permeable layer to block the flow of the crushed stone (step S50).

The elastic layer 50 is formed on the permeable layer 40 thus formed by mixing the elastic chip with a binder and flattening the same. The elastic chip may be made of a rubber chip or a cork chip. At this time, when the elastic chip is made of rubber chips, 80 to 85% by weight of rubber chips having a diameter of 5 to 8 mm and 15 to 20% by weight of binder are mixed to form an elastic layer. An elastic layer is formed by mixing 35 to 45% by weight of the cork chip having a thickness of ˜8 mm and 55 to 65% by weight of the binder (step S70).

However, since rubber chips are usually produced by regenerating waste tires, they contain harmful substances such as heavy metals contained in waste tires. Therefore, the use of rubber chips may cause odors or various physical diseases caused by harmful substances. Therefore, it is preferable to use cork chips, which are natural materials.

At this time, the cork chip exhibits elasticity, but has many internal voids, so that the cork chip is crumbly and broken while repeating a process of absorbing and evaporating moisture.

Therefore, in the present embodiment, while maintaining the elasticity of the cork chip as it is, the cork chip is manufactured and used as a method for preventing the absorption of moisture inside the cork and preventing evaporation of moisture inside the cork.

In more detail, in order to manufacture the cork chip, first, a mixture of 25 to 30% by weight of a urethane base, 25 to 30% by weight of a curing agent and 40 to 50% by weight of a diluent is mixed. The mixed solution is administered in a container and sufficiently stirred to maintain the temperature inside the container at 50 to 60 ° C. This is to prevent the natural curing of the urethane base and the curing agent.

And the mixture may be further added to the pigment to give a color to the finished cork chips. At this time, it is preferable to mix about 0.5-5 weight% of pigments using what corresponds to the intended color (step S71).

Cork crushed to 10 mm or less is introduced into the mixed solution. At this time, a variety of methods can be used to crush the cork, in the present embodiment was ground using a high speed mill. In the grinding process, only the cork made of the chip shape of 10 mm or less is used, and the dust of the cork is removed.

The cork is administered to the container containing the mixed solution is immersed in the mixed solution for 100 to 140 minutes. At this time, the amount of cork to the mixed solution is not important. This is because it is enough that the mixed solution only penetrates the pores of the cork to block the pores, and the cork only delivers the cork from the mixed solution after being immersed in the mixed solution.

In addition, when the cork is immersed in the mixed solution, when the resulting cork chip is bonded to the binder, the mixed solution is applied to the outer surface of the cork chip, thereby reducing the amount of binder used. In addition, when the cork chips are produced by the immersed cork, it is possible to suppress the release of moisture of the cork chips, thereby eliminating the disadvantage that the cork chips become crumbly even after long-term use. In addition, the wood cork chip can absorb the moisture, the absorption of moisture into the cork chip by the applied mixture is blocked, it is possible to prevent the volume expansion and decay of the cork chip by the water (step S72).

The immersed cork is taken out of the mixture and dried naturally. At this time, the mixed liquid is applied to the outer surface of the cork, and the applied mixed liquid penetrates into the pores of the cork to block the pores of the cork.

The cork may be poured into a solid plate and dried to form a shape corresponding to the solid frame. There is no particular limitation on the drying time, but about 3 to 4 hours are sufficient (step S73).

The dried cork is ground in a high speed grinder. Cork chips produced by the grinding can be a variety of sizes, it is used by selecting the size of 2 ~ 3㎜, 4 ~ 5㎜, 6 ~ 10㎜. However, without using a high speed grinder, the cork chips may be ground to a predetermined size in order to omit the sorting process (step S74).

On the other hand, the drainage path 20 is installed in the periphery of the target road surface 10 may be provided with a discharge mechanism 60 for discharging the water stored in the drainage path toward the playground. The discharge mechanism includes a pump 61, an inlet pipe 63 mounted at one end of the pump to allow the water stored in the drainage channel to flow into the pump, and a discharge end mounted at the other end of the pump to discharge the pressurized water from the pump. A discharge tube 65 and a nozzle 67 provided at the end of the discharge tube to radiate the pressurized water toward the side of the athletic field. Therefore, when the temperature of the road surface of the playground rises or a lot of dust is blown, the discharge mechanism 60 may be operated to lower the temperature of the playground or to prevent dust from scattering.

In addition, the water stored in the drainage path 20 may be utilized for various purposes. For example, it can be used for toilet or cleaning.

Next, the operation of the first embodiment according to the present invention will be described.

As shown in FIG. 4, when rain falls, rainwater falls on the elastic layer 50 and flows into the water permeable layer through minute pores of the elastic layer. Since the permeable layer 40 is made of crushed stone, and the voids are formed relatively large, rainwater introduced into the permeable layer can be quickly introduced and discharged.

At this time, since the waterproof sheet 30 is stacked at the bottom of the water permeable layer 40, rainwater introduced into the water permeable layer 40 is stored on the water permeable layer without being introduced into the ground. Rainwater is continuously stored in the permeable layer, and the rainwater is discharged to the drainage channel 20 through the drainage hole 23 when the rainwater rises to the formation height of the drainage hole 23. That is, the drain hole 23 serves as an overflow pipe in the permeable layer 40.

Rainwater flowing into the drainage channel 20 is stored while filling the drainage.

On the other hand, as shown in Figure 5, the rain water stored in the water permeable layer 40 is naturally evaporated and is discharged to the playground surface through the elastic layer 50. As the heat of the material constituting the elastic layer 50 is discharged by the evaporated water, excessive temperature rise of the road surface of the warm field is prevented.

In addition, rain water stored in the drainage path 20 may be sprayed onto the playground surface through the discharge mechanism 60 to cool the playground or prevent dust from scattering. The sprayed water is evaporated or flowed back into the permeable layer 40 to naturally evaporate, thus continuing the above-described role.

Second Embodiment

Next, a second embodiment of a method for forming an eco-friendly playground that is capable of storing and utilizing rainwater by permeation and evaporation according to the present invention will be described.

Figure 6 is a flow chart for a second embodiment of the method of forming an environmentally friendly playground that can be stored and utilized in the rain water by the pitcher and evaporation according to the present invention, Figure 7 shows a method of manufacturing a rubber magnetic chip according to the present invention 8 is a cross-sectional view of a playground constructed by the method according to the second embodiment of the present invention, FIG. 9 is a cross-sectional view showing a rainwater inflow and storage method, and FIG. It is a section section.

As shown, up to the step (step S70) of forming the elastic layer in this embodiment is the same as the first embodiment. However, in this embodiment, the artificial turf layer 70 is additionally installed on the elastic layer. Artificial turf layer 70 is composed of artificial turf mat 71 and the filler (73), the filler may be composed of a variety of materials. Generally, the filler 73 is used by mixing silica sand and rubber chips. However, as described above, since the rubber chips are used by recycling waste tires, they contain various harmful substances such as heavy metals. Rubber magnet chips without these are used alone or in combination with silica sand (step S80).

The manufacturing method of such a rubber magnetic chip is started from the step of collecting and dissolving the waste rubber magnet. Waste rubber magnets are used for stationery, toys, leaflets, etc. In particular, they are attached to the door border of the refrigerator so that the refrigerator door can be detached and sealed. At this time, when the refrigerator is discarded, the rubber magnet attached to the door frame is also discarded, resulting in an increase in waste and waste of resources. Therefore, in the present invention, it is easy to collect, but used to collect the waste rubber magnet attached to the refrigerator door with a lot of annual emissions.

At this time, when the rubber magnet is attached to the refrigerator door, the exterior material is coated to surround the rubber magnet. The exterior material is made of rubber or synthetic resin, and the exterior material and the rubber magnet may be separated to use only a rubber magnet. However, since the exterior material is bonded to the rubber magnet, it takes additional time and cost to separate the exterior material and the rubber magnet, and the amount of the exterior material is relatively small compared to the rubber magnet, so the exterior material and the rubber magnet may be collected and used as it is. Therefore, in the present invention, the waste rubber magnet is used as a meaning including not only the rubber magnet itself, but also a rubber magnet coated with an exterior material.

The waste rubber magnets thus collected may be dissolved as they are, but may be dissolved after being cut to an appropriate size for quickness and convenience of dissolution. At this time, the waste rubber magnet is preferably crushed to about 25 mm or less (step S81).

The rubber magnet is composed of a composite material made of fine powder of high-strength anisotropic ferrite and isotropic ferrite and synthetic rubber, and has all the flexibility, elasticity, and moldability of the magnet and rubber of the magnet. Material.

By the way, the rubber magnet is made of synthetic rubber produced by a chemical method, and therefore contains a trace amount of heavy metals. At this time, the content of the heavy metal is used below the environmental standard, and because it is significantly less than the waste tire, even if the rubber rubber chips according to the present invention by dissolving the waste rubber magnet can be significantly reduced the damage by heavy metal.

However, even in the case of trace amounts, heavy metals are included, so in order to further reduce such heavy metals, tourmaline may be added to the dissolved waste rubber magnet. At this time, the amount of tourmaline is preferably used in the range of 3 to 7% by weight based on the waste rubber magnet. If the tourmaline is added in less than 3% by weight, the effect of the tourmaline is insignificant, on the contrary, if it exceeds 7% by weight, the cost of the tourmaline increases, the overall manufacturing cost of the waste rubber magnet chip increases.

Herein, tourmaline is used to remove trace metals contained in waste rubber magnets because of the efficacy of tourmaline, which has the effect of decomposing and removing chlorine, odors, heavy metals and harmful substances in water. In addition, even when tourmaline was added to and mixed with the dissolved rubber, not water, the tourmaline was confirmed to remove heavy metals contained in the waste rubber. This is because the heavy metal contained in the waste rubber magnet is below the environmental standard, i.e., the content of the heavy metal is low. Therefore, if it is confirmed that the heavy metal is used above the environmental standard in the synthetic rubber used in the waste rubber magnet, the amount of tourmaline added It is preferable to increase (step S82).

The waste rubber magnets dissolved in this way are cut into a predetermined size while being extruded into an extruder (not shown) to produce chips. That is, when the waste rubber magnet is withdrawn from the nozzle of the extruder, a cutter (not shown) spaced a predetermined distance from the nozzle rotates to continuously cut out the waste rubber magnet. In this case, since the waste rubber magnet is discharged in the form of a rod from the nozzle and cut by a cutter, the waste rubber magnet is manufactured as a chip having a cylindrical shape having a predetermined height. And since this process is known to those skilled in the art as a so-called "squash", a detailed description of the process and the extruder and cutter used therein will be omitted (step S83).

Waste rubber magnets made of cylindrical chips are placed in a rotating mechanism (not shown) to form them into spherical chips. This is because when the rotating mechanism is rotated, the rubber magnet can be formed into a sphere while receiving centrifugal force due to the rotation of the rotating mechanism. The rotating mechanism has a central axis, and is provided with a plate-like rotating body connected to the central axis and rotated together with the central axis, the side of the rotating body is a semicircle so as not to be discharged to the outside while supporting a waste rubber magnet subjected to centrifugal force It is preferable to have a cross section in the form (step S84).

The waste rubber magnets formed into a spherical shape are solidified by being left at room temperature for at least about 1 hour to produce a rubber magnetic chip as shown in FIG. At this time, the time and temperature for solidifying the waste rubber magnet may be variously modified for the purpose of solidifying the waste rubber magnet. That is, it is possible to set the temperature lower than room temperature for rapid solidification (step S85).

Other configurations and operations according to FIGS. 9 and 10 are the same as in the first embodiment, and thus detailed description thereof will be omitted.

The rights of the present invention are not limited to the embodiments described above, but are defined by the claims, and those skilled in the art can make various modifications and adaptations within the scope of the claims. It is self-evident.
