Description

[0001] The present invention relates to a rainwater permeable block and a water-

The present invention relates to a rainwater permeability block storage tank measuring device, and more particularly, to a permeability block and an apparatus for measuring the stormwater in a storage tank that can be used for the utilization and recycling of rainwater.

Water is recognized as a very valuable resource. In particular, the average annual precipitation in Korea is 1.4 times higher than the world average, but the UN has designated Korea as a water-scarce country.

Most of the country is made up of short steep mountains, which makes it difficult to keep the reservoir, and it rains intensively in summer. According to a report by the United Nations' International Agency for Population and Behavior (PAI), the available water per capita is expected to reach 1199 to 1327 cubic meters by 2025.

 A few years ago, the winter drought became extreme. In Korea, there are 127.6 billion tons of annual rainfall. Seasonal and regional precipitation fluctuations are severe. In the flood season, only 26% of them are used as groundwater, dam and river water, and the remaining 40 billion tons are flowing into the sea. Even if only 5 ~ 10% of rainwater is used, winter drought can be solved.

Even rainwater management can solve a vicious cycle of floods and droughts.

Collecting rainwater collecting technology, filtering rainwater collected from houses and water from houses, recycling toilets and landscaping water, and technology for securing groundwater by infiltrating and storing rainwater into the ground.

 In recent years, interest in environmental issues has been increasing worldwide, and there has been an active application to technology development and architectural design for collecting and recycling rainwater beyond the use of less water.

In addition, each local government is trying various ways to recycle rainwater.

It is also necessary to measure the flow rate or pollution level for the recycling of rainwater.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail with reference to the preferred embodiments of the present invention with reference to the accompanying drawings. Like reference symbols in the drawings denote like elements.

1 is a view for explaining a configuration of a rainwater permeable block storage tank measuring apparatus according to an embodiment of the present invention.

Referring to FIG. 1, a rainwater permeable block storage tank measuring apparatus according to the technical idea of the present invention includes a block sensor unit and a storage tank sensor unit.

The block sensor unit may be embodied as being insertable into an environment-friendly waterproof block, and may communicate with a terminal (e.g., a computer, a mobile phone, etc.) of a manager by wirelessly.

       Block sensor part Eco sensor block sensor embedded in block

The storage tank sensor unit can sense data related to stormwater in the storage tank. The storage tank sensor unit may also transmit necessary data through wireless communication with the administrator terminal.

The storage tank sensor unit may include at least a sensor for measuring the amount of stormwater (rainwater) included in the storage tank. According to an embodiment, the storage tank sensor unit may also include a sensor for measuring an index indicating a pH of the storm or other contamination. By measuring the amount of stormwater stored in the reservoir, flooding in the city center can be prevented.

Also, the information sensed by the storage tank sensor unit can be compared with the information sensed by the block sensor unit, and the contamination source on the path of the drainage path or other stormwater can be predicted and corrected.

In addition, measures to adaptively remove pollution according to the contamination level of stormwater stored in the storage tank may be possible.

The permeable block may be implemented as a non-toxic eco-friendly material. Also, it can be implemented with excellent water permeability.

In order to realize the environment-friendly water permeable block composition according to the embodiment of the present invention, natural stone existing in nature such as gravel (natural gravel), silica sand, or crushed stone can be used as an aggregate. It goes without saying that such a natural stone may be subjected to a washing or cleaning process in advance. In the embodiment of the present invention, natural stones are used as aggregates as described above, so that pollution of the exterior by the aggregate can be prevented.

Only natural gravel, silica sand, or crushed stone may be used to prepare the environmentally friendly waterproofing block composition according to an embodiment of the present invention, and a plurality of natural stones may be used.

In order to realize the technical idea of the present invention, the natural stone can be selected, for example, as those having a diameter of 3 to 8 mm. The larger the diameter of the natural stone, the larger the permeability, but the strength of the permeable block can be lowered. Also, the larger the diameter, the higher the ratio of the binder to be blended.

Therefore, in one embodiment of the present invention, in order to obtain proper properties in terms of permeability and strength while being easy to obtain in a natural state, in an embodiment of the present invention, an eco-friendly water permeable block composition is manufactured from a natural stone having a diameter of 3 to 8 mm Respectively. At this time, the eco-permeable block composition may form one block layer, and the one block layer may be a composition in which the natural stone and the eco-friendly binder according to the embodiment of the present invention are mixed and cured.

According to another embodiment of the present invention, an environmentally friendly water permeable block composition having a plurality of block layers is prepared using natural stones having different diameters. The first block layer may be made of natural stone having a diameter of 3 to 8 mm as described above, and the second block layer may be made of natural stone having a larger diameter. The natural stone used for the production of the second block layer may be natural stone having a diameter of 10 to 15 mm according to the embodiment of the present invention. When the eco-friendly water permeable block composition is prepared so as to have a plurality of layers, the pores of the respective block layers are different in size or structure so that the lower soil on which the eco-friendly water permeable block composition is installed has relatively low water permeability It is possible to prevent the backflow of the storm toward the upper part of the environmentally friendly water permeable block composition.

Also, by forming a plurality of layers having different water permeability and strength, the water permeability and strength of the environmentally friendly water permeable block composition can be adjusted as needed. For example, permeability and strength of the entire environmentally friendly water permeable block composition can be controlled by adjusting the mixing ratio of the second block layer in a state where the mixing ratio of the aggregate and the binder in the first block layer is fixed.

In addition, permeability and strength can be adjusted by selecting different types of natural stones used for the first block layer and the second block layer.

First Embodiment

In one embodiment, an environmentally friendly water permeable block composition according to an embodiment of the present invention can be prepared using only natural gravel of 3 to 8 mm. That is, an example of producing the environment-friendly water permeable block composition with only one block layer is shown.

At this time, the block layer may be mixed so that the mixing ratio of the aggregate, that is, the natural gravel and the binder, is 10 to 30: 1. The mixing ratio of the aggregate and the binder may have a great influence on the properties of the block layer and / or the entire environmentally friendly water permeable block composition.

The higher the proportion of the binder in the mixing ratio, the lower the water permeability of the block layer or the environmentally friendly water permeable block composition. This is because the rate at which the binder fills the voids between the aggregates can be increased. Because of this property, the higher the proportion of the binder, the higher the strength of the block layer.

According to the embodiment of the present invention, when the natural stone having a diameter of 3 to 8 mm is used, the characteristics of the block layer according to the mixture ratio of the natural stone, that is, the aggregate and the binder, are shown in Table 1.

Classification (aggregate: binder weight ratio) Permeability coefficient (mm / s) Bending strength (N / mm ² ) 1 to 10: 1 Less than 1.0 20 or more 10 to 20: 1 1.0 to 3.5 10.1-20 20 to 30: 1 3.5 to 12 5.5 to 10.1

<Table 1: Aggregates using 3 to 8 mm diameter aggregate: Characteristics of block layer according to binder weight>

The experimental results in Table 1 were prepared by preparing five samples with the same mixing ratio and by extrapolating the range of each of the five samples.

As shown in Table 1, the higher the ratio of the binder in the mixing ratio, the lower the permeability. It can be seen that the higher the ratio of the binder is, the higher the bending strength is. The environmentally friendly water permeable block composition according to an embodiment of the present invention is selected to have a weight ratio of aggregate: binder of 20 to 30: 1 when natural stone (natural gravel) having a diameter of 3 to 8 mm is used as an aggregate. According to the criteria of KS F 4419: 2014, when the permeability coefficient is 1.0 or more, the permeability is set to 1 grade, and the bending strength is judged to satisfy the criteria when it is 4.0 or more in the case of the sidewalk and 5.0 or more in the case of the roadway to be.

Therefore, a weight ratio of 20 to 30: 1 may be selected so that the performance of permeability and bending strength are both excellent while using as few binders as possible. However, even if the aggregate and the binder are mixed at a weight ratio of 10 to 20: 1 according to the embodiment, the water permeability and the bending strength both satisfy the reference value or more, so that a weight ratio of 10 to 20: 1 may be selected according to the embodiment. As a result, according to the embodiment of the present invention, the aggregate and the binder may be mixed to have a weight ratio of 10 to 30: 1, and in a more preferred embodiment, a mixing ratio of 20 to 30: 1 may be used.

On the other hand, as described above, there has been a problem that the storm that has passed through the conventional permeable block is contaminated by aggregate and / or binder. In order to solve such a problem, an environmentally friendly binder may be used as the environmentally friendly water permeable block composition according to an embodiment of the present invention.

The environmentally friendly binder may be selected from the group consisting of an acrylic resin, a polyurethane resin, a polyester resin, a toluene diisocyanate trimer (TDI Trimer), a cyclohexylmethane diisocyanate (H12MDI), a toluene diisocyanate (TDI) A mixture of a mixture of methylene diphenyldiisocyanate (MDI), hexamethylene diisocyanate (HMDI) and polypropylene glycol (PPG), and a surfactant.

Examples of such eco-friendly binders are disclosed in Korean Patent No. 10-1522556, " Method for producing eco-friendly adhesive composition and eco-friendly adhesive composition produced thereby "filed by the inventor of the present invention. The eco-friendly binder to be applied to the present invention can be produced using the materials and / or mixing ratios disclosed in the above-mentioned registered patents. As described in detail in the above patent application, the environmentally friendly binder has excellent adhesion and no yellowing phenomenon. When the curing is accelerated, the environmentally friendly binder does not contain heavy metals or volatile organic compounds, .

Therefore, it is effective that the storm that has passed through the environment-friendly water permeable block composition according to the technical idea of the present invention is not contaminated by the binder. Further, according to the technical idea of the present invention, the aggregate is made of natural stone without using waste or cement.

Therefore, there is no need for a treatment process for purifying heavy metals or volatile organic compounds contaminated by the volatile organic compounds in order to recycle them.

In order to prepare an environmentally friendly water permeable block composition according to this embodiment, it is preferable to mix the aggregate and the binder so that the weight ratio of the aggregate and the binder is 20 to 30: 1, and then the material mixed in the mold, It can be subjected to a block molding process to apply a constant pressure. Then, after a predetermined time, the material is demolded in a mold and subjected to a curing process, whereby the environmentally friendly water permeable block composition can be produced.

Second Embodiment

According to another embodiment of the present invention, the anti-reflection ball block may have a first block layer and a second block layer.

As described in the first embodiment, the first block layer is formed of natural gravel having a diameter of 3 to 8 mm as an aggregate, and the second block layer is a aggregate having a diameter of 10 to 15 mm.

The first block layer may be a block layer formed by mixing the aggregate and the binder in a weight ratio of 20 to 30: 1 as described in the first embodiment.

The second block layer may be a block layer formed using natural stones having a diameter of 10 to 15 mm.

A block layer using natural stone having a smaller diameter may be formed so as to be positioned higher than in the environmentally friendly waterproofing block composition. Therefore, the problem that the permeability of the garbage or other contaminants interferes with the voids of the block layer to deteriorate the permeability may be relatively small.

 In the case of the second block layer, a mixture ratio of the aggregate and the binder may be different from that of the first block layer. According to an example, since the second block layer uses natural stone having a larger aggregate diameter, the mixing ratio may be selected such that the ratio of the binder is higher than the mixing ratio of the first block layer.

According to the embodiment of the present invention, when the natural stone having a diameter of 10 to 15 mm is used, the properties of the block layer, that is, the second block layer according to the mixing ratio of the natural stone, that is, the aggregate and the binder,

Classification (aggregate: binder weight ratio) Permeability coefficient (mm / s) Bending strength (N / mm ² ) 1 to 10: 1 Less than 2.0 15 or more 10 to 20: 1 2.0 to 7.0 7 ~ 15 20 to 30: 1 7.0 to 20 5.5 to 7

<Table 2> Aggregates with 10-15 mm diameter aggregate: Characteristics of block layer according to binder weight>

As shown in Table 2, as the ratio of the binder to the aggregate and the binder is increased, the permeability is lowered. It can be seen that the higher the ratio of the binder is, the higher the bending strength is. On the other hand, when the mixing ratio of the same or similar binder ratio is used in the second block layer having a larger aggregate diameter, the permeability is higher, while the bending strength is lower.

Therefore, in order to have similar permeability and flexural strength as the first block layer, the second block layer may be selected so that the ratio of the binder used in the second block layer is higher than that used in the first block layer. According to an embodiment of the present invention, in the case of the second block layer, the weight ratio of the aggregate to the binder may be 10 to 20: 1. Of course, as shown in Table 2, the aggregate and the binder may be mixed so as to have a weight ratio of 20 to 30: 1 even in the second block layer.

The binder used in forming the second block layer may also be the same eco-friendly binder as the binder used in the first block layer.

In order to produce an eco-permeable block composition having a first block layer and a second block layer, the aggregate and the binder are mixed so as to have a weight ratio of 10 to 20: 1 to form the second block layer, It is possible to carry out a block molding process in which a material blended in the mold is inserted to mold the size of the mold. And a material blended at a weight ratio of 20 to 30: 1 to form the first block layer may be inserted into the mold so as to be located on top of the material for the second block layer.

Since the first block layer and the second block layer are respectively mixed with the binder, it is not necessary to further apply a binder to bond the first block layer and the second block layer separately, and the material for the first block layer is inserted The block forming process can be performed by applying a constant pressure. After a certain period of time, the material is demoulded and cured in the mold to produce the environmentally-friendly waterproofing block composition including the first block layer and the second block layer.

Test results for the detection of heavy metals, volatile organic compounds, and other pollutants after passing water through the environmentally-friendly water permeable block composition according to the above-described Example 2 are as follows.

Detection of PBBs (POLYBROMINATED BIPHENYLS)> ingredient content Detection limit BROMOBIPHENYL Not detected 1 mg / kg DIBROMOBIPHENYL Not detected TRIBROMOBIPHENYL Not detected TETRABROMOBIPHENYL Not detected PENTABROMOBIPHENYL Not detected HEXABROMOBIPHENYL Not detected HEPTABROMOBIPHENYL Not detected OCTABROMOBIPHENYL Not detected NONABROMOBIPHENYL Not detected DECABROMOBIPHENYL Not detected

<Table 6. Detection of Volatile Organic Compound (VOC)> ingredient unit result VOC g / L Not detected (detection limit 0.01)

As can be seen from the results of <Table 3> to <Table 6>, the rainwater passing through the environment-friendly water permeable block composition according to the technical idea of the present invention is not contaminated.

It is to be understood that the same effect will be obtained also in the case of Embodiment 1 using the same binder and natural stone.

As a result, according to the technical idea of the present invention, it is possible to provide an eco-friendly water permeable block having high water permeability and high strength using a natural stone and an environmentally friendly binder. In addition, since it can be produced using only a natural stone and a binder as described above, there is an effect that it can be manufactured very easily.

In addition, since natural stones and an environmentally friendly binder are used, there is no pollution of storm that has passed through the environment-friendly water permeable block composition, which is very advantageous for excellent recycling.
