The present invention relates to a rainwater reservoir and a block for forming a reservoir of the reservoir, and more particularly, to install in a basement such as an apartment complex, a road, a waterway, a park, and the like to collect rainwater and store it in a reservoir. A rainwater reservoir designed to reuse stored rainwater and blocks available for the reservoir.

Considering the current trend of increasing water consumption, Korea, which is recognized as a water shortage country, is in danger of falling into a water famine country without developing alternative water resources. The construction of dams to secure water resources is limited due to environmental problems and the water consumption of the people is gradually increasing, so that new alternative water resources are urgently needed. In addition, in Korea, a lot of rain more than 1,200mm per year, but most of it is difficult to efficiently use and manage water resources due to the rainfall trend that is concentrated in some of the summer season. In addition, in urban areas, many paved roads and rainwater drainage systems are designed to introduce most of the natural rainwater into the rivers, resulting in the rapid outflow of rainwater during heavy rains. There was a shortage of water and the dryness of urban areas was caused, resulting in a vicious cycle of water supply.

Therefore, while reducing the risk of human and property damage due to summer floods and winter droughts due to intensive rainfall, and increasing water shortages, interest in recycling and stormwater management is increasing. have.

The present invention has been made to solve these problems and requirements, in urban areas and areas where large-scale housing site development plans are made, providing a storage system associated with storm water systems designed around rivers, such as heavy rains It is a first object of the present invention to provide a rainwater storage device capable of temporarily buffering rainwater during a heavy rain and then naturally discharging it to perform a buffer function against heavy rainfall.

It is a second object of the present invention to provide a water storage device configured to be able to adjust the water storage period in addition to the temporary water storage and natural discharge functions such that the rainwater stored during the water storage period can be used for other purposes.

A third object of the present invention is to provide a block capable of efficiently constructing a water tank of the water storage device described above.

The first object of the present invention is an inlet through which rainwater flowing on a road surface can be introduced, a sedimentation tank for removing contaminants from rainwater introduced through the inlet, and the rainwater in communication with the sedimentation tank and the contaminants are removed. It is possible to achieve by providing a rainwater storage device having a storage space for storing and having a bottom surface of the storage space is installed at the same or higher position than the lower surface of the inner space for the soil removal manhole of the storm drain system.

A second object of the present invention further has an auxiliary reservoir having an auxiliary storage space connected to the reservoir and having an upper surface of the auxiliary storage space installed at a position equal to or lower than a lower surface of the inner space of the soil removal manhole. It can be achieved by a rainwater reservoir containing.

A closed hexagon block consisting of a block consisting of a diaphragm and a diaphragm for closing the through space; The one block is simultaneously inserted into the concave groove of the one hexagon block and the concave groove of the other hexagon block while the outer surface of the one hexagon block and the outer surface of the other hexagon block are in contact with each other. And it can be achieved by providing a reservoir having a connecting pin for fixing the other one block with each other.

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

1 and 2 show a preferred embodiment of the rainwater reservoir of the present invention. As shown, the rainwater storage device includes a rainwater inflow means 10, the first settling tank 20, the second settling tank 25, the reservoir 30, the auxiliary reservoir (40).

Rainwater inlet means 10 is composed of a plurality of inlets that can inject rainwater during rainfall, which includes a roadway inlet 12 and pedestrian roads (hereinafter referred to as "driveway") is a road for vehicles Sidewalk inlets 14 through which rainwater flows in " walkways " The driveway inlet 12 is formed at a boundary portion between the sidewalk and the driveway formed on both sides of the driveway, specifically, a jaw portion (stair shaped portion) of the boundary from the driveway to the sidewalk, and is preferably disposed at regular intervals along the roadway. . The sidewalk inlet 14 is formed through the sidewalk, preferably a plurality of holes of a predetermined size on the throughhole after forming a through-hole through the sidewalk so as to be connected to the inlet passage 13 of the driveway inlet 12 It is formed by positioning a metal mesh having a.

Rainwater flowing into the water storage device by the rainwater inflow means 10 reaches the first sedimentation tank 20. The sedimentation tank is to remove sand, earth and sand, and other suspended impurities contained in the rainwater from the rainwater. In a preferred embodiment of the present invention, a two-stage settlement tank is installed. The first settling tank 20 includes a plurality of first inclined plates 22 and a first settling tank outlet 23. The first inclined plate 22 functions similar to the inclined plate used in a conventional immersion tank, and since many inclined plate configurations are known, detailed description thereof will be omitted. Rain water passing through the first settling tank 20 is introduced into the second settling tank 25 through the first settling tank outlet 23.

Sediment removal of the first sedimentation tank 20 is configured to allow all rainwater stored in the water storage device of the present invention to escape by natural discharge after a certain time elapses after the rainfall. For the convenience of deposit removal, the first settling tank is preferably installed near the ground or as close to the ground as possible.

The second settling tank 25 includes one large second inclined plate 24. Rainwater from which first contaminants are removed in the first sedimentation tank 20 is additionally removed from the second sedimentation tank 25. Rainwater from which the contaminants have been removed from the second settling tank flows into the reservoir through the reservoir inlet 32.

The reservoir 30 has a constant reservoir space for storing rainwater therein. The reservoir 30 is preferably formed using the hexagonal blocks 70, 71 to be described later. The installation height of the reservoir 30 is determined so that the lower surface of the reservoir space is at the same or higher position than the lower surface of the soil removal manhole 29 of the storm drain system. In this way, the rainwater accommodated in the reservoir 30 during rainfall can be naturally discharged from the reservoir 30 without the help of a special discharge device when the water level of the surrounding storm drain system is lowered. In addition, the reservoir 30 is connected to the storm drain system and includes a reservoir discharge pipe 34 that can control the discharge. The reservoir discharge pipe 34 may adjust the rate at which rainwater is discharged to the river by adjusting the amount of rainwater naturally discharged from the reservoir 30 when the water level of the surrounding storm water drainage system is lowered.

As shown in FIG. 2, near the bottom bottom of the second inclined plate 24 of the second settling tank 25, a soil discharge outlet 28 is formed and connected to the soil removal manhole 29 of the storm drain system. . According to such a configuration, since the storm drain system and the second sedimentation tank 25 can communicate with each other, when the rainfall is over and the water level of the storm drain system is lowered, the manhole 29 for soil removal from the second soil sink 25 is removed. As rainwater flows into the furnace, sediment deposited on the bottom of the second inclined plate 24 may flow into the soil removal manhole 29. Therefore, the sediment deposited on the second inclined plate 24 can be transferred to the soil removal manhole 29 without the help of a separate soil transportation device or soil removal device. For example, additional installation of the screw-type soil removal device 26 may move solidified deposits or viscous deposits, which are not easily carried by rainwater flow, to the soil removal manhole 29.

3A and 3B illustrate a hexagonal block for forming a water tank, and show a state in which two hexagonal blocks, each of which is a unit, are connected to each other.

The hexagonal block 70 shown in FIG. 3A is a through block, and six pillar members 70a of the same size are coupled to each other in a substantially hexagonal shape so as to have a through space at the center thereof. T-shaped grooves 72 are formed. The hexagonal block 71 shown in FIG. 3B is a closed block, and is substantially the same as the through block, but different from the through block 70, and further includes a diaphragm 76, so that the six pillar members 71a have approximately the same. It has a configuration in which the central through space formed by coupling with each other in a regular hexagonal shape is closed, and each pillar member 71a is formed with a T-shaped groove 73. The pillar members 70a and 71a are made of polyethylene (PE) or polypropylene (PP) resin, and preferably made of recycled plastic is preferable in terms of environmental friendliness.

3A and 3B, one pillar member 70a or 71a is a hollow member having a constant thickness, width and length and having a rectangular cross section. The cross section of the pillar members 70a and 71a may have a closed polygonal cross section of various shapes in addition to the quadrangle. The outer surfaces 70c and 71c of the pillar members 70a and 71a have a flat shape so that the outer surfaces 70c and 71c of the pillar members 70a and 71a can be in uniform contact with the outer surfaces of the pillar members 70a and 71a of the other blocks 70 and 71 of the same shape. The T-shaped grooves 72 and 73 are preferably formed to penetrate through the entire thickness direction (the thickness direction of the hexagonal block when the pillar members are bonded to each other to form a hexagonal block), and the cross section may have various shapes in addition to the T-shaped. .

Each hexagon block 70, 71 is coupled to each other by the H-shaped connecting pin 74 as shown in Figure 3c. 3A and 3B, both ends of the connecting pin 74 are inserted into the respective T-shaped grooves 72 and 73 formed in the two hexagonal blocks 70 and 71 to be connected to each other so that the two hexagonal blocks 70 or 71) are coupled to each other (for example, through hexagonal blocks 70 through each other, closed hexagonal blocks 71 between each other).

An example of a connecting member is shown in FIG. 3d. The connecting member 78 shown in FIG. 3D includes a plurality of engaging surfaces 81 in contact with the surfaces of the hexagon blocks 70 and 71, and T-shaped grooves 79 formed in the respective engaging surfaces 81. Has a cross-section. Accordingly, the connecting member 78 shown in FIG. 3D may support the hexagonal blocks 70 and 71 extending in four directions perpendicular to each other at one place. The connection member used in the present invention has a similar basic configuration (for example, a configuration having a plurality of coupling surfaces and T-shaped grooves formed on each coupling surface in contact with the surface of the hexagonal block) and various connecting members in different shapes only in cross-sectional shapes. Can be used. For example, the connection member having an L-shaped cross section may join blocks in two orthogonal directions, and the connection member of the T-shaped cross section is three-way, and the connection member of the straight cross section (“一”) is coupled to one surface. It may have a pair of engaging surfaces.

Meanwhile, the reservoir 30 may be formed by, for example, a method of forming sidewalls on four sides of the outside of the reservoir 30. In this case, by using the closed hexagonal block 71 of the present invention to form the outer wall of the reservoir 30, in order to form the outer wall of the reservoir 30 of this type L-shaped connecting member at the four corners that the side wall is connected Is needed.

 Therefore, using the closed hexagonal block 71, the L-shaped connection member and the above-described connection pin 74 of the present invention, by combining the hexagonal block 71 in the horizontal and vertical directions to facilitate the storage tank (30) Can be formed.

As another example of forming the reservoir 30, the reservoir 30 may be configured to have one or more orthogonal inner walls in the center thereof to be more rigidly configured and to have a larger reservoir space. The reservoir 30 of this type uses the through and closed hexagonal blocks 70 and 71 of the present invention, a connection member having an L-shaped cross section, a connection member having a T-shaped cross section, and a connection member having an X-shaped cross section. Can be formed. The through hexagonal block 70 is used to form an orthogonal inner wall, and the closed hexagonal block 71 is used to form an outer wall.

In order to form a larger reservoir 30 or to efficiently perform the reservoir installation, it is preferable to use a unit block assembly having various configurations as shown in FIGS. 4A to 4E.

The unit block assembly shown in FIGS. 4A to 4C has a configuration in which a closed hexagonal block 71 is disposed at a front side, a through hexagonal block 70 is disposed at a rear side, and a connection member 78 is positioned at both sides to fix it. The outer wall assembly is located at the outermost side of the reservoirs 30 and 40. The unit block assembly shown in FIGS. 4D and 4E has a configuration in which through-hole hexagonal blocks 70 are disposed on both front and rear surfaces, and connecting members 78 are positioned at both sides to fix them, and the inner wall used to construct the inner wall. Assembly. The connecting member 78 in these unit block assemblies may be one of the connecting members of the X-shaped cross section, the L-shaped cross section, the T-shaped cross section and the straight cross section described above.

The unit block assembly for the outer wall may be used to form the outer wall of the reservoir by placing the diaphragm 76 at the outermost side of the reservoir space. It is preferable to configure the shape of each unit block assembly so that other unit block assemblies can be engaged with each other above and below one unit block assembly. For example, the block assembly of FIG. 4A and the block assembly of FIG. 4B are configured to engage each other in the vertical direction. In addition, the side wall unit block assembly of the outer wall unit block assembly can be placed side by side unit block assembly for the inner wall through the hexagonal block 70 can be made in communication with each other. In this way, the unit block assembly for the inner wall can be continuously arranged laterally to configure the entire reservoir 30 using only the unit block assemblies.

The auxiliary reservoir 40 has an auxiliary reservoir space inside, similar to the reservoir 30, and the upper surface of the auxiliary reservoir space is installed at the same height or lower than the lower surface of the soil removal manhole 29. The auxiliary reservoir 40 has a structure in communication with the reservoir 30 so that the rainwater during the rainfall first fills the auxiliary reservoir 40 first and then fills the reservoir 30. Even though the rainwater stored in the reservoir 30 after the rainfall is discharged naturally through the storm drainage system, the rainwater stored in the secondary reservoir 40 located below the soil removal manhole 29 of the storm drainage system is not naturally discharged. Is stored. The water thus stored may be discharged to the outside through the intake pipe 44 using the intake pump 42 and used again for another purpose.

It is preferable to form both the reservoir 30 and the auxiliary reservoir 40 of the modified embodiment using the hexagonal blocks 70 and 71 of the present invention.

6A shows the water storage device of the second embodiment of the present invention.

The storm receiver 52a is preferably installed on the roof of a building or the like to collect rainwater that has not reached the ground. Rainwater collected in the rainwater receiver 52a is removed from the sedimentation tank 52c through the water collecting pipe 52b and then flows into the water storage tank 50.

Returning to 6a again, the reservoir 50 is not limited to the height of installation, unlike the reservoir 30 of the first embodiment, but is preferably provided underground. The reservoir 50 is provided with a soil removal device (54). Since the water storage device of this embodiment is not connected to the storm drain system, it is preferable to use a conveyor type soil removal device. As in the previous embodiment, the reservoir 50 may be configured using the hexagonal blocks 70 and 71 of the present invention.

The water stored in the reservoir 50 is processed by the simple processing device 56 to have the required water quality before reuse. The water treated by the simple treatment device 56 is used where water of a certain level or more is required, such as water for heavy water or living water during a disaster. The water discharged by the water intake pump 58 may be used where water quality is not greatly required, such as for park management or facility management.

According to the rainwater storage device of the present invention, in urban areas and large residential land development areas, it is possible to reduce the burden of sewerage and rivers, and to prevent natural disasters by preserving natural water circulation systems.

Storage and reuse of rainwater can reduce the supply of water, thereby reducing the burden of drinking water or domestic water.

In addition, according to the hexagonal block of the present invention, it is possible to easily install a more robust water tank within a short construction time compared to the case of forming with ordinary concrete.
