Description

Drainage instrument and Drive method of the Same}

The present invention relates to technologies related to civil engineering, construction, and building equipment. In particular, it discharges or turns into groundwater rainwater, runoff water, and floodwater flowing in from the outside, or regenerates groundwater that flows back through the soil area, crustal area, or rock area into a drainage system. By continuously mass producing eco-friendly energy by circulating water resources smoothly and establishing a new drainage maintenance system for each country, each country, city, and village that introduced this system provides the people with the benefits of efficient management of water resources, providing clean drinking water. It is about drainage devices and their operation methods that provide living conditions for a clean and clean life.

Recently, as the development of residential land has increased due to population concentration in cities, paving of roads and sidewalks where people and cars pass is rapidly progressing.

Typically, driveways are paved with a road surface made of impermeable asphalt concrete or cement concrete, and sidewalks are paved with a sidewalk surface made of sidewalk blocks. However, conventional paving materials for sidewalks or driveways do not take into account the permeability of the ground and are mostly made of concrete or It is a paving material made of asphalt as an aggregate and is composed of an impermeable material that does not allow water or air to pass through.

Due to rapid urbanization where rivers and wetlands are rapidly disappearing, the rate of impervious areas in metropolitan areas such as Seoul, where water cannot seep into the ground surface, continues to increase, and the expansion of impervious areas due to asphalt and concrete reduces the city's rainwater infiltration ability. As a result, a significant amount of rainfall does not seep into the ground and simply flows into the river through sewer pipes, including pollutants on the ground surface, without the process of filtering out pollutants due to road surface washing, worsening the water circulation environment in the city. As a result, it is not possible to respond flexibly to droughts or floods even in areas with abundant rainfall, and water pollution in rivers increases due to depletion of groundwater, drying of rivers, urban heat island and tropical night phenomenon due to distortion of the thermal environment, and water contamination by unfiltered rainwater. There are problems that can cause natural disasters, such as the death of trees.

Past water management in urban areas, including roads and complexes, was a system for rapidly draining excess stormwater runoff from developed areas and was focused on flooding. However, climate change, temperature rise, distortion of the water cycle, and increased outflow of non-point pollutants require supplementation of environmental hydraulic functions in the construction field, and efforts for such change are driven by green growth and smart growth, focusing on developed countries. It appears as a major content in the construction field.

In addition, in large cities such as Seoul, most of the groundwater and rainwater that flows from subways, underground communication and power conduits, and building basements are discharged through storm drains without any special purpose. When groundwater and rainwater are discharged in this way, the city's Soil desertification accelerates and soil wetness worsens, reducing water evapotranspiration efficiency, causing urban heat islands and adversely affecting the microclimate.

The government and local governments such as Seoul City have introduced technology to retain and infiltrate rainwater as a technology element of low impact development (LID), a core technology for urban water circulation, leading to green infrastructure projects and moist water cycle urban projects. However, there is still insufficient research and development on technology to fundamentally reduce flying fine dust from major sources of flying fine dust such as roads and rooftops by utilizing this water cycle low-impact development technology (LID technology).

Rainfall characteristics in Korea show various rainfall patterns by season, and even with the same rainfall phenomenon, various outflows of pollutants occur in various forms depending on the characteristics of the watershed. In addition, pollutants contained in rainfall runoff are contained in large amounts in rainfall runoff generated during initial rainfall, whereas they are contained in trace amounts in rainfall runoff generated during initial rainfall, so initial rainfall runoff is discharged after removing and treating pollutants. And, for the rainfall runoff after the initial stage, a method of discharging it as is, omitting the pollutant removal process, is adopted.

In most systems for selective treatment of rainfall runoff, the initial rainfall runoff water that has undergone the pollutant removal and treatment process and the initial rainfall runoff water that has omitted the pollutant removal and treatment process are discharged into the discharge water system as is.

Our country is one of the water-scarce countries designated by the United Nations, and we are at a point where the development, maintenance, and management of groundwater as well as surface water are becoming more important than ever. Therefore, in order to efficiently utilize water resources in urban areas in preparation for future water shortages, it is necessary to develop core technologies for collection, purification, and storage that occur at each stage of the water cycle in order to reuse rainfall runoff from roads and complexes with low pollution levels. do.

In addition, before urbanization, most of the rainwater infiltrated into the ground, but now the ground surface is not permeable and is paved with impermeable surfaces such as asphalt or concrete blocks, which increases the amount of rainwater runoff into the ground and reduces underground infiltration, leading to depletion of groundwater. The underground environment is devastated, water cannot be absorbed underground, and the ground surface generates extremely high heat, which causes the urban heat island phenomenon, which raises the temperature of the sidewalk surface. The important function of sewers is to facilitate the drainage of rainwater during the rainy season or heavy rain. By paralyzing the system, problems such as rainwater drainage and water pollution, where most rainwater is discharged into rivers through sewers, are increasing.

Engineeringly, the amount of water that reaches the river is determined by the basin area, rainfall intensity, runoff rate, etc. Climate change can change rainfall intensity, and an increase in impervious layer prevents water from seeping into the ground and increases the runoff rate, so the impervious area The increase in rainwater infiltration, evapotranspiration, and groundwater runoff decreases, and surface runoff and runoff into rivers greatly increase, leading to increased environmental problems such as urban flooding, depletion of groundwater, and deterioration of river water quality and ecosystem. Damage to the city's water circulation system is caused by the rainy season. In times of drought, the country faces difficulties in using water and becomes a 'water-scarce country' because rainwater cannot be stored efficiently.

Therefore, in order to solve the above-mentioned problems, innovative measures for ‘water circulation and management’ are required to ensure water circulation by facilitating the natural infiltration, tributary, and evaporation of rainwater.

[Example]

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1A and 1B are diagrams showing a drainage device according to an embodiment of the present invention.

Referring to FIGS. 1A and 1B, the drainage device 1000 discharges or converts rainwater, running water, and flood water flowing in from the outside into groundwater, or regenerates groundwater that flows back through the soil area, crustal area, or rock area into drainage. The device includes a drain left support 100, a drain right support 200, and a water permeable block 300.

First, the drain left support 100 generates a left opposing force on the left side to support the left sided water pressure automatically generated by the inflow of rainwater, running water, and flooding.

Likewise, the drainage right support 200 generates a right opposing force on the right side to support the right-side water pressure automatically generated by the inflow of rainwater, running water, and flooding.

Furthermore, as part or all of at least one stone, gravel or aggregate is filled in the drainage passage created as much as the separation distance between the left support of the drain 100 and the right support of the drain 200 based on the permeable block 200, It will be said that the drainage device 1000 according to an embodiment of the invention forms a drainage ditch in the form of a natural waterway.

Since the left and right sides of the drain left support 100 and the drain right support 200 may vary depending on the viewing angle or the viewpoint of a person skilled in the art, the reference numerals hereinafter will be given as 100 (200) to reduce errors.

The left (right) opposing force can be said to be a resistance force that acts in the opposite direction of the moving direction when an object moves relatively, and is opposed to the water pressure generated by rainwater, running water, and flooding flowing into the drainage device 1000 of the present invention. It can be said to be a reflection force that supports the plates provided on the left and right sides, that is, the left or right supports (100 (200)) of the drain.

As can be seen from Figures 2 and 3, the left or right drain support 100 (200) has a first piece hole 150 in the upper area of the inner surface of one side, a second piece hole 155 in the lower area of the inner surface of one side, A first screw hole 160 in the upper region of the inner surface on the other side, which is opposite to the upper region of the inner surface on one side, a second screw hole 165 in the lower region of the other inner surface, and at least one male socket member on the side of one side. (L1, L3,..,2L-1) (110) and at least one female socket hole (L2, L4,..,2L) (130) are arranged alternately in odd-even order, or on one side of the other. At least one other female socket hole (M1, M3,.., 2M-1) 140 and at least one other male socket member (M2, M4,.., 2M) 120 alternately in odd-even order. It is placed as you go.

Accordingly, when fastening the drain left or right support 100 (200) with another drain left or right support 100 (200) of the same model, at least one male socket member (L1, L3,..., 2L) -1) (110) has at least one female socket hole (M1', M3',.., 2M-1') (140) arranged on one side of the left or right support (100 (200)) as another drain. The first socket is coupled, and at least one female socket hole (L2, L4,...,2L) 130 is connected to at least one male socket member (M2', M4') arranged on one side of the left or right support in another multiple. ,..,2M') (120) and the second socket are combined. At the same time, the first piece is combined with the first and second piece holes (150, 155) and the first 'and 2' screw holes (160, 165) formed on the inner surface of one side of the left or right support respectively.

In addition, when the drain left or right support 100 (200) is fastened with another drain left or right support 100 (200) of the same model as the drain left or right support 100 (200), at least one At least one other male socket member (L1') arranged at intervals on one side of the left or right support (100 (200)) in another multiple of the female socket hole (M1, M3,...,2M-1) (140) , L3',...,2L-1') (110) and the third socket are combined, and at least one male socket member (M2, M4,...,2M) (120) is connected to the left or right support in another multiple. At least one other female socket hole (L2', L4',...,2L') 130 arranged at a gap on one side of the fourth socket is combined with the first and second screw holes (160, 165). In another drain, the second piece is combined with the first 'and 2' piece holes (150, 155) formed on the inner surface of one side of the left or right support, respectively.

To facilitate understanding of the present invention, the reference numbers for accessories of the left or right drain support (100 (200)) are different from the reference numbers for accessories of the other left or right drain supports (100 (200)) mentioned above. It is assumed that the drawing numbers of the accessories of the left or right drain support (100 (200)) are the same.

In other words, the method of combining the drain left or right support 100 (200) with another drain left or right support and another drain left or right support is understood to be a simple combination of several identical components, and those skilled in the art From this point of view, it is emphasized that the 1 to 4 socket combination and the 1st and 2nd piece combination are mechanically and structurally bound to be combined that way, and that this is regarded as a self-evident fact, so that the same component is treated as if it were a different component. As the context is sufficient without distinction, and there is no reason to use different reference symbols, avoid describing them separately in a way that makes them difficult to understand.

Subsequently, the permeable block 300 is installed so that the plug-in member of the drain left support 100 (200) is plugged into a selected one 310 of a plurality of insert lines to reduce the load of the drain left support 100 (200). Support and fix the load of the drain right side support 100 (200) by placing it so that the plug-in member of the drain right support 100 (200) is inserted into another selected one (310) of the plurality of insert lines. It performs the role of giving.

In addition, the permeable block 300 uses the drainage passage created by the separation distance between the left support of the drainage channel (100 (200)) and the right support of the drainage channel (100 (200)) to let rainwater, running water, and flood water flow or to drain the water. Let it pass through the ground. <See Figures 4 and 5>

In addition to the essential components, the drain device 1000 according to an embodiment of the present invention includes a side tilt prevention bar 170, a support bar on both sides 210, a lid 400, and a connection bracket 220 as described below. Includes additional device configuration.

More specifically, the side tipping prevention bar 170 of the drain device 1000 is configured such that the plug-in member 105 of the drain left or right support 100 (200) is one selected from a plurality of insert lines and the other selected one 310. ), it plays a role in preventing signs of collapse due to side tilting due to the load of the left or right support (100 (200)) of the drain or left or right water pressure. <FIG. 2, FIG. See 3>

As shown in Figure 8, the two-side support binding bar is inserted into and connected to the first and second connecting parts 180 made on the upper inner surface of the left or right drain support 100 (200), respectively, so that it is connected to the left or right drain channel. While the right supports (100 (200)) are kept parallel to each other, the drain left or right support (100 (200)) is automatically induced between the drain left support (100 (200)) and the drain right support (100 (200)) according to the external pressure. It prevents 100 (200)) from leaving the outside. <See FIGS. 6, 7A, and 7B>

In addition, the lid portion 400 inserts the first and second sill grooves 410 into the first and second sill locking members 190 respectively provided at the upper center of the inner surface of the left or right drain support 100 (200). It protects the opening and prevents forced infiltration of rainwater, running water, flooding, and soil, suspended matter, by-products, or dirt that may enter from outside. It is equipped with an up-and-down sliding button or a left-right sliding button to turn multiple trench-type inlets on and off. It performs the role of opening and closing. <See Figure 11>

However, as can be seen through Figure 7b, the lid portion 400 is not necessarily provided with the first and second threshold grooves 410, so it can be attached to the connection bracket 220 without the first and second threshold locking members 190. It can be easily mounted on the top of the left or right support (100 (200)) connected by. In addition, since the lid portion 400 is not an absolutely necessary component, the drainage device 1000 can be easily installed without the lid portion 400.

For reference, the drain device 1000 of the type without the lid portion 400 will be referred to as an open-type drain device.

The connection bracket 220 is a joint that is fixedly attached to the automatically created joint surface between the left or right drain support (100 (200)) and at least one other left or right support (100 (200)) installed side by side on the same line. (接合) connection is performed to increase the left (right) opposing force by 1.1 to 5 times. <See Figures 9 and 10>

The connection bracket 220 is also easy to sufficiently fix and install the left or right drain support 100 (200) by combining the male and female socket holes and fastening the pieces, so it is not necessarily a necessary configuration. However, since it must be taken into account that the coupling and fastening of the left or right support 100 (200) may collapse due to external pressure, the necessity of the connection bracket 220 will be mentioned in another embodiment.

Here, the features and advantages of the drainage device according to the embodiment of the present invention will be described below. That is, at least one of the drain left support (100 (200)), the drain right support (100 (200)), and the permeable block (300) is made of 70 to 90% by weight of polypropylene (PP) based on the total 100% by weight. It will be said to be a material manufactured by mixing and mixing 10 to 30% by weight of talc. In particular, it is manufactured by dissolving all 100% by weight of polypropylene without applying a mixing ratio of 10 to 30% by weight of talc, or talc. As a substitute for , 10 to 30% of glass powder is used to make up 70 to 90% by weight.

Referring to FIG. 12, the driving method of the drainage device is to discharge or transform rainwater, running water, and flooding flowing in from the outside into groundwater, or to regenerate groundwater flowing back through the soil area, crustal area, or rock area into the drainage. .

The support on the left side of the drain creates a left opposing force on the left side to withstand the left-biased water pressure automatically generated by the inflow of rainwater, running water, and flooding (S100).

The support on the right side of the drain creates a right opposing force on the right side to withstand the right-side water pressure automatically generated by the inflow of rainwater, running water, and flooding (S200).

The permeable block supports and fixes the load of the drain left support by installing the plug-in member of the drain left support into one selected from a plurality of insert lines (S300).

The permeable block is installed so that the plug-in member of the support on the right side of the drain is plugged into another selected one of the plurality of insert lines to support and fix the load on the support on the right side of the drain (S400).

In addition, the permeable block uses the drainage passage created by the separation distance between the support on the left side of the drain and the support on the right of the drain to let rainwater, running water, and flood water flow or allow drainage to pass through the ground (S500).

Although the above has been described with reference to embodiments, those skilled in the art will understand that various modifications and changes can be made to the present invention without departing from the spirit and scope of the present invention as set forth in the following patent claims. You will be able to.
