The present invention relates to a pitcher block for permeating rainwater in rainy weather and a manufacturing method thereof.

In particular, due to the recent abnormal weather phenomenon and localized heavy rainfall, a large amount of rainwater flows into lowlands at a time, so the water permeability block and water permeability with excellent water permeability to minimize flood damage and flood damage caused by this A method of manufacturing a block is provided.

With the development of industry and the increase of population, society has been rapidly urbanized in recent years, and as urbanization progresses, natural drainage has increased due to the increase of asphalt roads, cement fire roads, and water permeable blocks. In the limited situation, if the rainfall increases more than a certain amount, flooding is caused in the lowland due to the lack of capacity of the processing facility that can handle the increased rainfall. Therefore, we are trying to increase the capacity of sewage pipes in accordance with this, but it is not possible to solve this by simply adding a part of sewage pipes in the system where sewage pipes are connected from branch lines to trunk lines and car collection pipes. Inflow increase should be dealt with by setting a separate route, but this will also be difficult to overcome unless most of the regions already have sewage pipes fully expanded.

Therefore, it is necessary to install rainwater reduction facilities that can reduce stormwater runoff and reduce stormwater runoff and reduce peak runoff.

Therefore, the present invention effectively treats rainwater during the rainy season during the rainy season and reduces the amount of rainwater concentrated in the downstream area, and at the same time, delays the rainwater arrival time as much as possible, effectively concentrating downstream. It can manage the amount of rainwater effectively, such as using the rainwater during dry season, while keeping the rainwater absorbed by the soil, and prevents water dripping due to the excellent water permeability. Therefore, by supplying the purified water to the groundwater, it is possible to purify the groundwater quality and to relieve the increase of the groundwater cultivation and the heat island phenomenon, and to regenerate it by the natural water circulation cycle, and the soil is excellent during heavy rains such as typhoons and floods. Soil is absorbed and held in place, so that the rainwater is retained a lot and the voids are well developed. To provide service to be excellent permeability block and a manufacturing method having the property that the effective permeability (雨水) to do it is an object.

Hereinafter, with reference to the accompanying drawings a preferred embodiment of the present invention in more detail,

EXAMPLE

① Selection process of materials

It is preferable to use cement as specified in KSL5201,5204,5210,5211 or more than that.

Aggregate should be clean, hard, durable and of suitable particle size, contain no harmful amounts of clay lumps, organic matter, thin or long flakes, etc. Preference is given to using.

It is preferable to use a high strength polycarbonic acid high performance AE water reducing agent as the admixture. This improves the slump retention performance and durability, improves the material separation resistance, and prevents the flow of cement paste to improve the work efficiency.

② Cleaning of aggregate and removing impurities

The aggregate selected in the material selection process is used to share the washing method using water and the air washing method to remove the fine particles and other organic impurities contained in the aggregate. In other words, before the aggregates reach the aggregate conveying conveyor, the air is blown out to remove some fine powder, and then stopped in the conveyor belt to spray the water again to wash the aggregates.

If the summer and the amount of sunshine is enough during the cleaning, the aggregate is dried until it becomes dry, and when the temperature is low and the humidity in the air is higher than 70%, make the surface dry enough in the shade and drying equipment in the conveyor belt. In this case, the aggregate washing water is collected in the collecting chamber and the finely divided particulates and organic matter are separated through the outlet of the lower part, and the water of the upper part is recycled back into the washing water.

③ Blending process

Aggregate (about 78.4% of the total weight of the material) from which the washing and other impurities are removed is added to a mixer, and water (about 3.1% of the total weight of the material) is added thereto, and mixed with it. After the first formulation, cement (approximately 17.4% of the total weight of the material) is added after the first formulation, and the water remaining while the secondary formulation is sufficient for the cement paste to adhere to the aggregate (approximately 0.8 of the total weight of the material). %) And high-strength polycarbonic acid high performance AE water reducing agent (about 0.3% of the total weight of the material) mixed with dilution, and sprayed evenly to the secondary blended aggregate to form a third blend.

When mixing, steel mixing is used, and it is preferable to use a horizontal mixer or a pen mixer so that cement paste can be evenly attached to the aggregate within a short time.

The formulation of the materials is expressed as a weight ratio to aggregate, and the total weight of the material is the sum of the weights after all the aggregates, cement, water, and admixture are combined.

As an example of the blending process, about 2098 kg of the aggregate from which the washing and other impurities have been removed are added to a mixer, and about 82.4 kg of water is added thereto, and mixing is performed to form a primary blend, and the primary During mixing, about 466kg of cement is added to the aggregate so that the cement paste can be sufficiently attached, and the mixture is diluted with about 20.6kg of remaining water and about 9.3kg of high-strength polycarbonic acid high performance AE water reducing agent mixed with This is evenly sprayed on the secondary blended aggregate to form a third blend.

④ Molding process

Complete the mixture up to the tertiary mixture within 3 ~ 5 minutes from the mixer (mixer) and inject it into the mold, so that the mixture to form a flat plane, and then 3600 ~ 7200 vpm vibration to prevent the cement paste from lowering The first molding process is achieved by vibrating upward from the bottom plate of the mold by using a high frequency vibrating device forming a high frequency vibrating device, and using the vertical vibrating device from the top, compressing to 100 ~ 160kgf / cm2 simultaneously with 1150 ~ 2500 vpm. While completing the secondary molding process, the molding process is completed.

It is preferable that the molding process is completed within 30 minutes before the cement paste dries after blending so as to prevent dry dryness of the aggregate.

⑤ Curing process

Blocks that have undergone the molding process are kept from being impacted from the outside and steam cured for about 2 hours at 60 to 70 degrees Celsius, and then cured for 8 to 12 hours in a natural dry state.

⑥ Polishing process

Before the aggregate is put into the mixer, the coarse aggregate surface is polished to 1.5 ~ 3mm to make the surface roughness and smoothness of the coarse aggregate. Improves permeability performance and keeps the block beautiful.

⑦ Coloring process

In order to use general epoxy, paint, etc. by using water during the polishing process, dry painting process must be repeated, and separation and lifting of materials occur, so that general epoxy and paint are not only inefficient, but also polished block surface. When water is absorbed in the water and reaches a fully saturated state, the mixed coloring cement paste flows down and fills the voids. Therefore, to prevent this, water is removed from the upper surface using air after the tax rate (sludge removal). Coloring should be done in the state, and the surface should be rapidly dried using the same material. The upper part polished by adding 40% aqueous pigment water ratio (W / C) to the mixture of 70% white alumina cement and 30% color cement. Use a roller in the form of thin paste to form a coating film on the W evenly to the colored to the distribution to be secured to the apertured and water-pervious and maintain a rapid surface drying state.

As an example, when mixing 100 kg, the white alumina cement is 70 kg and the color cement is 30 kg, and since the aqueous pigment evaporates, it is not included in the volume and weight, and thus the aqueous pigment is the sum of the weights of the white alumina cement and the color cement. 40% of the water, so 70 + 30 × 40% = 40 (kg) to supply the aqueous pigment is added.

The excellent runoff prevention water permeation block 100, which has been subjected to the manufacturing process as described above, consists of a gap 20 between the aggregate 10 and the aggregate 10, while achieving a durability of 210kgf / cm2 compressive strength and 50kgf / cm2 of bending strength. Permeability of 0.5cm / sec or more of continuous air gap allows 20 ~ 50mm of precipitation to penetrate into the permeation block and flows 30 ~ 40% of groundwater into the groundwater. It is possible to minimize the damage of flooding, flooding, etc. by rainwater flows into the lowland at a time by flattening, and in harmony with the global environment without destroying the ecosystem, considering the finiteness of global resources and environmental preservation. It has the same durability and excellent water permeability, and thus provides a water permeation block for rainwater reduction, which can be suitably used for rainwater reduction facilities.

The present invention relates to a water permeation block for rainwater reduction and a manufacturing method thereof.

By using the permeation block for rainwater reduction according to the present invention, the rainwater infiltrates some of the rainwater into the permeation block in rainy weather, and the soil absorbs the rainwater and retains it in the dry season. By reflowing rainwater, it is possible to efficiently manage rainwater during heavy rains such as typhoons and floods, as well as to reduce the amount of rainwater flowing into sewer pipes and streams, thereby reducing the damage of floods and flooding. . In addition, due to its excellent permeability, the effect of infiltrating rainwater into the ground is maximized, which can solve the insufficient groundwater problem and alleviate the heat island phenomenon.
