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 if there is no development of an alternative Susan source. 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.

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 may be performed after a certain time after the rainfall is over, all the rain water stored in the water storage device of the present invention by natural discharge. 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.

 Therefore, using the closed hexagonal block 71, the L-shaped connecting member 78b and the connecting pin 74 of the present invention by combining the hexagonal block 71 in the horizontal and vertical directions, the water tank of the illustrated form 30 can be easily formed. On the other hand, in the formation of the reservoir 30 of the type shown in Figure 4f, because the hexagon block 71 is disposed only on the outside of the reservoir space, only the closed hexagonal block 71 is used.

Referring to FIG. 4G, the reservoir 30 shown in FIG. 4F has a more rigid configuration than the reservoir 30 shown in FIG. 4F having an inner wall perpendicular to the center thereof, and thus is suitable for the reservoir 30 having a larger reservoir space. . Reservoir 30 of this type has a through and closed hexagonal blocks 70 and 71 of the present invention, a connecting member 78b having an L-shaped cross section, a connecting member 78c having a T-shaped cross section, and an X-shaped cross section. It can be formed using a connecting member 78 having. The through hexagon block 70 is used to form the inner wall, the closed hexagon block 71 is used to form the outer wall.

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 and a through-shaped hexagonal block 70 is disposed at a rear side and a connection member 78a is positioned at both sides thereof 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 78a are positioned at both sides to fix them, and the inner wall used to construct the inner wall. Assembly.

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.

5 shows a water storage device of the present invention according to a variant embodiment. The reservoir further includes an auxiliary reservoir 40. 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.
