Here, the protection member 143 may be further fixed to accommodate the porous plate 141 on the outer side of the body 111.

Excavation holes are excavated to install the manhole 110 equipped with the filtration unit 140 on the ground, the excavation hole is preferably formed larger than the manhole 110, the manhole (hole) on the bottom surface of the excavation hole 110) can be seated.

The penetration guide member in the penetration prevention member 170 in a state in which the penetration prevention member 170 is installed on the bottom surface of the excavation hole to prevent the foreign substance from moving to the manhole 110 while preventing the separation of the penetration guide member 160. After filling the 160 to a certain height, the manhole 110 may be seated on the upper surface of the penetration guide member 160.

When the manhole 110 is seated on the bottom surface of the excavation hole or the upper surface of the penetration guide member 160, the sewage pipe 120 is installed in the sewage installation hole 112 formed at the lower end of the body 111 of the manhole 110. It is connected to the sewage pipe (120 '), install the rain pipe 150 in the rainwater installation hole 114 formed in the upper end of the manhole 110 body 111 is connected to the rain pipe (150').

Here, by connecting the inside of the sewage, excellent conduit 120, 150 and the backflow preventing member 190 by the shaft 191, the backflow preventing member 190 by the flow of rainwater around the shaft 191 Rotating and opening and closing, when the rain water does not flow, it is to close the inside of the excellent conduit 120, 150.

In addition, as shown in Figure 6, the good, excellent conduits 120, 150 can be formed integrally by connecting to one pipe (120a), which is the rainwater flowing in excess of the initial rainwater and capacity It can be drained to a sewage treatment plant.

The inlet conduit 180 may be installed in the inlet installation hole 115 formed at the upper end of the body of the manhole 110.

In addition, the buoyancy gate 130 is coupled to the end of the sewage pipe 120 installed in the sewage installation hole 112 by the shaft 131, the buoyancy gate 130 around the shaft 131 according to the water level, upper and lower Allow it to rotate in the direction.

When the conduits and buoyancy gates 130 are installed in the manhole 110, the earth and sand are filled in the excavation hole, and the lid 110 ′ is seated in the seating groove 111 ′ of the manhole 110. The installation of the groundwater hydration treatment system 100 of the rainwater of the present invention is completed, and when the penetration preventing cloth 170 is installed in the excavation hole, the circumference of the side surface of the manhole 110 is filtered through the filtering member ( After filling higher than 140, the penetration preventing member 170 surrounds the penetration guide member 160, which guides the underground penetration of rainwater that has passed through the filtration unit 140, as well as foreign matter in the ground is the manhole 110. To prevent backflow.

Referring to the operating process of the present invention installed by the above process, as shown in Figures 7 to 9, during the rain, the rainwater moves along the surface of the manhole 110 body 111 through the lid 110 ' Inflow to or through the inlet conduit 180 is introduced into the manhole 110, the body 111 inside.

At this time, foreign matters heavy such as soil among the foreign matters contained in the rainwater flowing into the body 111 of the manhole 110 through the lid 110 ′ and the inlet conduit 180 are disposed on the bottom surface of the body 111. At the same time as the foreign matter is deposited light weight is increased according to the water level stored in the body 111, the buoyancy gate 130 connected to the sewage pipe 120 and the shaft 131 as the water level rises is the shaft It rotates upward about 131.

When the water level of the water to rotate the buoyancy gate 130 upwards is higher than the sewage pipe 120, the buoyancy gate 130 is rotated according to the water level and the rain water is drained to the sewage pipe 120, the The reverse flow prevention member 190 installed inside the sewage pipe 120 by the initial rainwater drained to the sewage pipe 120 rotates upwardly about the shaft 191 to open the sewage pipe 120. At the same time, the rainwater is drained to the sewage pipe 120 'through the open sewage pipe 120.

When rainwater is drained to the sewage pipe 120 ', only the initial rainwater containing nonpoint pollutants on the ground surface is drained to the sewage pipe 120', so that the total amount of rainwater is drained to the sewage treatment plant through the sewage pipe 120 '. In addition to reducing the load on the sewage treatment plant, it is possible to reduce the river pollution caused by the initial rainwater.

When the water level inside the body 111 increases because the amount of rainwater flowing into the body of the manhole 110 is greater than the amount of rainwater drained into the sewage pipe 120, the buoyancy gate 130 according to the water level The sewer pipe 120 is closed while rotating upwardly about the shaft 131.

In this case, as the flow of the initial rainwater drained to the sewage pipe 120 is stopped, the backflow prevention member 190 rotates downwardly about the shaft 191 with its own weight to close the inside of the sewage pipe 120. As the sewage pipe 120 is closed, the level of rainwater flowing into and stored in the body 111 rises faster than when the sewage pipe 120 is opened.

When the level of rainwater in the body 111 rises and is higher than the filtration unit 140, the stored rainwater in the body 111 is transferred to the filtration filter 142 through the porous plate 141 of the filtration unit 140. At the same time as the foreign matter is filtered by the filtration filter 142, it is discharged to the outside of the manhole 110 via the porous plate 141.

The rainwater discharged to the outside of the manhole 110 flows into the penetration guide member 140 via the protection member 143, and the protection member 143 has a body of the manhole 110 to accommodate the porous plate 141. Since it is installed in the curved (111) it can protect the filter unit 140 from the earth pressure below the ground surface.

In addition, the rain water flowing to the penetration guide member 140, when the particles pass through the penetration guide member 140 formed of small gravel or crushed aggregate and porous blocks, the porosity of the penetration guide member 140 is enhanced to the rain water Since this flows easily through the penetration preventing cloth 150 and flows into the ground at the same time, it is possible not only to temporarily store rainwater, but also to prevent the ground from drying out.

Here, the penetration preventing cloth 150 is preferably formed of any one of the geotextiles or non-woven fabric that can prevent the inflow of soil in the ground while the rain water passing through the penetration guide member 140.

Although rainwater flows through the filtration unit 140 into the ground, the amount of rainwater flowing into the body 111 is high and the rainwater level is higher than that of the rainwater conduit 150. Rain water is drained, by the flow of the rain water drained to the storm pipe 150, the backflow prevention member 190 installed inside the storm pipe 150 is rotated upward with respect to the shaft 191, storm pipe 190 Rainwater is drained to the rain pipe 150 'through the rain pipe 150 that is open at the same time.

Through the above process, the initial rainwater is drained to the sewage treatment plant through the sewage pipe 120, and then the rainwater that the water level rises while being stored and flowed into the body 111 through the filter unit 140 to the ground. As it flows into the river through the storm drain 150, non-point pollutants are not drained to the river by the initial rainwater, which not only prevents the pollution of the river but also prevents the drying of the ground, thereby reserving rainwater resources and ecosystems. It can prevent destruction.

On the other hand, when the rain does not stop the rainwater flows into the body 111 of the manhole 110, when the level of the rainwater inside the body 111 is lowered, the flow of rainwater drained to the storm drain 150 is of course stopped The non-return member 190 installed inside the storm drain 150 closes the inside of the storm drain 150 while rotating downward about the axis 191 by its own weight, thereby preventing the odor flowing back into the storm drain 150. It can be blocked.

In addition, as the level of rainwater inside the body 111 is lowered, the buoyancy gate 130 not only flows through the filtration unit 140 but also the sewage pipe while the buoyancy gate 130 rotates from the top to the bottom about the shaft 131. While the rainwater is drained to the sewage pipe 120 until the water level is lower than that of the sewage pipe 120, the backflow preventing member is discharged by the flow of the rain water drained to the sewage pipe 120. 190 rotates upward about the axis 191 to open the sewage pipe 120 to allow the rainwater to be drained, and if the water level is lower than the sewage pipe 120, the backflow prevention member 190 is the shaft By rotating downward about the 191 to close the inside of the sewage pipe 120, the odor that flows back into the sewage pipe 120 may be blocked.

The buoyancy gate 130 rotates downward with respect to the shaft 131 according to the lowering level in the body 111 to open the sewage pipe 120 and wait for the next operation.

Here, the sediment deposited on the bottom surface of the manhole 110 body 111 should be able to maintain the function of the present invention by periodically dredging and also cleaning and replacing the filtration filter 142.
