The present invention is made of a salt which readily dissolves in water, wherein a plurality of cations are ionically bonded to anions charged on the surface of the soil, and an anion is ion-bonded to cations charged on the surface of the cement to mediate binding between the soil particles and the cement particles It plays a role. In addition, due to the characteristics of each component, hydration, cementation and water absorption are promoted, so that the cementation effect is expressed early and the strength is enhanced.
In the present invention, the raw material composition is mixed only with cement without addition of other components, thereby constituting a soil fire. Since cement is not limited to these types, general portland cement, slag cement, crude steel cement, etc. can be used alone or in combination.

When a large amount of cement is used to solve the problem, There is a problem that cracks are generated.
The present invention solves the above problems and utilizes a soil fire which is a mixture of cement and a raw material composition which is a main component of a metal salt to induce the bonding between the soil and the cement, By accelerating the action, it is possible to promote the solidification and to express the high strength.
According to the present invention, in producing the soil concrete using the field soil, the site soil and the soil fire according to the present invention are mixed at an appropriate ratio. In this case, the mixing ratio may vary depending on the required properties, but it is preferable that the soil fire is mixed in a ratio of 0.1 to 1.0 part by weight based on 100 parts by weight of the field soil.
Here, one kind of powder selected from oyster shell powder and purified water sludge powder or 1 to 5 parts by weight of two kinds of industrial by-product mixed powder may be further mixed and used.
At this time, general equipments which can be uniformly mixed in mixing and stirring the field soil, soil fire and industrial by-product mixed powder can be used. For example, a stirrer equipped with a four-row multi screw at an angle of 8 degrees Can be used and can be evenly stirred while rotating at a speed of 500 to 700 RPM. At this time, a grinding apparatus (for example, a roll mill) may be provided in the stirring apparatus to mix and stir soil particles and powder (or mixed powder) in the form of fine particles.
The composition thus prepared can be used as a material for constructing concrete pavement as it is by mixing an appropriate amount of water. The powder (or mixed powder) obtained from the industrial by-products can further strengthen the strength and provide economical effects. Secondary environmental pollution can be prevented by recycling industrial by-products.
Ingredients utilizing industrial by-products that may be included in the present invention may be selected from oyster shell powder and purified water sludge powder. When the mixed powder is composed of a mixture of oyster shell powder and purified water sludge powder, the content ratio of each component is preferably 10 to 90% by weight of oyster shell powder and 10 to 90% by weight of purified water sludge powder.
Water is mixed with the composition thus obtained, and the mixture is homogeneously stirred again to obtain a slip concrete, and the thus obtained slip concrete is to be installed on a construction site.
Then, a filter pad is prepared as in the above step (B). The filter pad is a filter pad made of an elastic material that transmits only fine particles of soil such as sand or marathon, but does not permeate water. Specifically, it is made of EPDM (ethylene propylene diene rubber) rubber powder or 20 to 70 weight 5 to 20% by weight of a styrene-butadiene-styrene (SBS) rubber component, 5 to 20% by weight of PE (polyethylene) fiber, 10 to 40% by weight of a binder and 10 to 20% by weight of a process oil, The pad for the filter is made to have a pitch hole smaller than the diameter of the sand and the master particle. Therefore, the surface layer of the soil is not passed through, and only the water of good quality is permeated.
The water permeable pad thus obtained is excellent in elasticity and has characteristics of excellent durability, water resistance and chemical resistance.
Subsequently, a water management system for a playground is constructed by using the obtained silicate concrete and a pitcher pad.
First, the ground is uniformly ground, and then the soil concrete obtained in the above (A) is laid on the top of the ground to compaction and cure. Specifically, the site soil is collected using a road stabilizer or a tractor, the soil concrete according to the present invention is evenly mixed, water is sprayed thereon, and the soil concrete is directly applied to the construction site And work on it.
Then, the laid sole concrete is plastered using a roller. At this time, a water collecting guide layer capable of guiding the stormwater to the water collecting facility is installed, and the water collecting guide layer may be provided with an impervious layer such as porous concrete, porcelain pipe, and vinyl.
In addition, a water collecting facility such as a collecting unit is installed on the outer side of the soil protection layer made of the siliceous concrete.
The water collecting facility can be constructed by installing a U-shaped cross section as a whole on the outer side of the ground protection layer and installing a collecting unit at a certain point.
Then, after compaction of the soil concrete is completed, the compaction soil concrete is cured. In the present invention, the curing of the soil concrete is completed at a room temperature condition, specifically about 10 to 50 캜, usually about 3 to 5 days. Therefore, compared with the curing time (about 28 days or more) .
In the present invention, the soil protection layer formed by curing the soil concrete has a water absorption rate of about 8 to 12%, including a fine pore structure inside, unlike the conventional concrete or the ascon. Therefore, And oxygen can be supplied, so that microorganisms can be inhabited in the soil, so that life force can be infused into the soil, thereby having an effect of maintaining the original function of the soil.
In the present invention, after the soil protection layer is installed using the soil concrete in the same manner as described above, the filter pad is installed for the water permeability, and the sand and sand are sandwiched therebetween. In the present invention, since the filter pads serve as a conventional aggregate layer, it is possible to reduce costs and resources by not using aggregates such as rubble and crushed stone. In addition, the soil protection layer made of silk concrete functions to safely support the surface layer.
In the present invention, since the filter pad does not pass the particles of sand and sand, it acts as a barrier, permeates only water, has elasticity and durability, and plays a role of firmly and resiliently maintaining the structure of the playground .
Then, a matallo and sand (silica sand) are laid on the upper part provided with the filter pad, and the construction of the playground is completed.
Specifically, the present invention is characterized in that the above-mentioned marathon and sand (including sea-marine) layers are laid at a thickness of 10 to 15 cm, the soil concrete is laid and compacted at a thickness of 10 to 15 cm, The rainwater can be recycled by collecting the rainwater by providing a filter pad for water permeation between the ground protection layers.
In addition, the present invention may further include a device for preventing dust from being blown from the playground by recycling water stored in the excellent management and recycling system to a dryer such as a drought. That is, the water collecting facility of (C) is further provided with a spraying device (for example, a sprinkler) capable of spraying the collected water into the playground, so that the water collected in the excellent season can be recycled in the dry season.
Further, in the present invention, the water collecting facility of (C) may spray water automatically collected at the dry season using a solar panel or the like to a playground or an aviation area to suppress dust generation.
In addition, the present invention may further include an apparatus that can use the water stored in the water collecting facility as a water tank. This has the advantage of being able to recycle good resources.
Hereinabove, the method of constructing the athletic field excellent management and recycling system and the athletic field excellent management and recycling system according to the present invention have been described in detail with reference to the drawings.
The athletic field excellent management and recycling system constructed by the method according to the present invention is excellent in water permeability and can prevent a playground from turning into a mud when it is stormed or thawed, Therefore, it is possible to prevent the dust from being scattered and to prevent the risk of injury due to the micro-soil loss of the surface layer, and to supply oxygen and nutrients to the soil under the ground layer, thereby maintaining the original function of the soil.
Therefore, not only the game facilities such as school grounds, soccer grounds, baseball courts, but also a wide range and efficiently in the case of the military campground, the tracks inside and outside the apartment complex for jogging, the park walkway, the children's playground or bicycle road within the apartment complex, Can be used.
