Description

Inflow tank, rainwater inflow treatment system and rainwater reduction system using same {inflow tank, system for inflowing and treating of rainwater, and outflow reduction system of rainwater using the same}

The present invention relates to a runoff reduction system (or a storage system), in particular, using a rubber beam and gebion walls, an inflow tank that can quickly and accurately serve as a runoff reduction facility in the event of a flood and block large amounts of soil and floats, A treatment system and a stormwater abatement system having the same.

In general, due to the increase in buildings and the increase of land surface pavement rate, rainwater flows into sewer or river at once without heavy flooding during heavy rains, and flooding may occur as a result of exceeding the inflow allowance. On the other hand, a small amount of inflow into the rivers causes problems due to deterioration of water quality and depletion of groundwater. For this reason, the technology to control the amount of runoff into rivers by storing rainwater in a rainwater reduction system composed of concrete or synthetic resin was developed.

Conventional stormwater abatement systems generally use a sedimentation tank as a stormwater inlet treatment system to prevent soil and suspended matter from entering.

1 shows an example of a conventional stormwater discharge reduction system.

The conventional rainwater discharge reduction system shown in FIG. 1 is disclosed in Korean Patent Laid-Open Publication No. 2011-0138050 (published on December 22, 2011), and the rainwater flows into the immersion tank 10 and one side of the immersion tank 10. It is divided into filter main body 20 that is connected to the installation, the interior of the filter main body 20 is partitioned into a distribution tank 21 and the filtration tank 23 and the filtration module 40 laminated in multiple layers in the filtration tank 23 inside. ) Is installed.

The sedimentation tank 10, contaminants such as oil and the like contained in the rainwater floats on the water surface and contaminants such as stones, sand, etc. among the contaminants contained in the rainwater sink to the bottom to be included in the rainwater. To separate the contaminated material.

The upper part of the immersion tank 10, the filter main body so that the rainwater flows into the filtration main body 20 and the inlet pipe 41 and the contaminants separated from the contaminant to communicate with the interior of the immersion tank 10 to the filter main body 20 ( A connecting tube 50 communicating with 20 is installed.

In the conventional stormwater reduction system as shown in Figure 1, the sedimentation tank (10) is in communication with the filter main body 20 by the connecting pipe 50 installed on the upper, usually by the vortex action, precipitation action, etc. It can be seen that the contaminants having a large specific gravity such as sand, etc. do not sink to the lower part of the sedimentation tank 10 and then have a structure in which the rainwater on the upper part of the sedimentation tank 10 is discharged to the filter main body 20.

However, rainwater flowing out during flooding is a problem of rainwater flow due to a large amount of soil and suspended matter, there is a problem that it is not easy to separate the pollutants with only the sedimentation tank (10).

On the other hand, as long as the time required to separate the contaminants by the sedimentation tank 10, the time that the rainwater flows into the filter main body 20 is delayed, and by such a delay, the conventional rainwater discharge reduction system is quick for the initial rainwater. There is a problem that can not respond.

On the other hand, since the amount of rainwater flowing out to the filter main body 20 is limited by the connecting pipe 50 installed on the upper part of the sedimentation tank 10, the conventional rainwater discharge reduction system can efficiently respond to the initial rainwater. There is also a problem that can not be.

If the stormwater flooding from the river is not dealt with promptly and efficiently, traffic and pedestrian traffic may be impaired or, in severe cases, traffic may be impaired, resulting in safety accidents. Accidental accidents are required to quickly and efficiently treat stormwater, including soil and suspended solids.

2 illustrates one embodiment of a storm runoff reduction system in accordance with the present invention.

Referring to FIG. 2, the inlet 104 includes a connecting conduit 104a, a rubber beam 104b, and an inlet tank 104c.

The conduit 104a provides a rainwater inflow path from the rainwater conduit 102, and a rubber beam 104b is installed on the rainwater inflow path provided by the conduit 104a. The upper height of the rubber beam 104b is preferably matched to the flooding risk level of the region where the storm drain 102 is installed.

The rubber beam 104b blocks the rainwater inflow path when the water level of the rainwater conduit 102 is less than the flooding risk level, and opens the rainwater inflow path when the waterflow level of the rainwater conduit 102 is greater than or equal to the flooding risk level. On the other hand, the inflow tank 104c filters out the soil and suspended matter contained in the rainwater flowing through the rainwater inflow path.

The storage unit 106 is a storage tank 106a for storing rainwater flowing through the inflow tank 104c, a soil suppression wall 106b having a predetermined height, and a discharge pipe 106c on the bottom surface of the storage tank 106a. It includes.

Rainwater discharged to the discharge pipe 106c of the reservoir 106 is discharged to the discharge conduit 110 via the outlet 108. The outlet 108 may be configured as a manhole, and may include an overflow pipe 112 for overflow.

Although not shown, a prefabricated rainwater storage frame may be installed in the storage tank 106a. Such rainwater storage frame may include a perforated tube and a prefabricated body unit supporting the perforated pipe.

Since the rubber beam 104b is installed on the rainwater inflow path provided by the connecting conduit 104a, the cross-sectional shape of the rainwater inflow pipe 104a preferably matches the cross-sectional shape of the rubber beam 104b. Has a rectangular cross section as the rainwater inlet pipe 104a, but is not limited thereto.

Rubber weir (104b, Rubber Weir) is installed across a river or river and looks like a tube to control the water level by limiting or freezing the flow of water by expansion and contraction by the injection and discharge of air.

The upper end of the rubber beam 104b is preferably matched to the flooding risk level of the storm conduit 102. When the water level of the rainwater conduit 102 reaches the flooding risk level, the air discharge valve 104e for introducing the rainwater through the connection conduit 104a and discharging the filling filled in the rubber beam 104b is operated to automatically open the rubber beam. 104b is slaughtered. After flooding, the rubber beam 104b is standing by injecting air manually and automatically (instrumentation equipment). The method of automatically operating the air discharge valve 104e comprises a bucket-type switchgear using a bucket or a sub-type switchgear using a buoy.

FIG. 3 shows an outline of the operation of the rubber beam shown in FIG. 2 and shows that a bucket type opening and closing device is adopted.

Referring to FIG. 3, the air discharge valve 104e is installed in the air discharge manhole 202. When the bucket 104f becomes heavy due to the rainwater flowing in through the rainwater inlet 104d, the bucket 104f is lowered, whereby the air discharge valve 104e is opened. On the contrary, when the bucket 104f is raised, the air discharge valve 104e is closed.

The inlet of rainwater inlet 104d is located at or slightly above the flooding risk level of storm drain 102. Accordingly, when the water level of the rainwater pipe 102 exceeds the flooding risk level, the rainwater flows in through the rainwater inlet 104d, and as a result, the air discharge valve 104e is opened to discharge the air of the rubber beam 104a.

When the air of the rubber beam 104b starts to be discharged, the rubber beam 104b is pressed by the hydraulic pressure applied to the rubber beam 104b in the rain pipe 102 to promote the air discharge in the rubber beam 104b and finally As a result, all of the air filled in the rubber beam 104b is discharged so that the rubber beam 104b is in a doped state. When the rubber beam 104b is in a doped state, the rainwater flowing from the rainwater pipe 102 is introduced into the inflow tank 104c through the connection pipe 104a. The rainwater inlet 104d should be installed at two or more places including the reserve because the rainwater should be introduced quickly and accurately at the time of flooding risk. Rainfall outlet 104g is for discharging rainwater filled in the bucket.

In the present invention, an example of a bucket type opening and closing device is shown as opening and closing the air discharge valve 104e, but a child opening and closing device using a bucket and a buoy may also be used.

Referring again to FIG. 2, the inflow tank 104c is configured in the form of a water tank, and at least one side wall contacting the storage tank 106a is formed of a wall of gabion 204 (hereinafter referred to as a gabion wall). Preferably, the gabion wall 204 is stacked in an inclined manner after the upper and lower surfaces, that is, the width becomes wider toward the bottom and narrows toward the top. More preferably, the gebion wall 204 is constructed in such a manner as to surround a part of the edge of the storage tank 106a.

FIG. 4 shows a top view of the inlet tank shown in FIG. 2.

Referring to FIG. 4, the inflow tank 104c includes a housing 206 and a gabion wall 204 having a rainwater receiving space therein. The part shown by the dotted line is the gebion wall 204, and it is shown that this gebion wall 204 was built in the form which encloses a part of the edge of the storage tank 106a. This is to allow the rainwater to quickly move from the inflow tank 104c to the storage tank 106a by increasing the contact area between the inflow portion 106 and the storage tank 106a.

5 briefly illustrates a connection relationship between the Gebion wall and the reservoir.

GABION (GABION) is a civil structure in which wire meshes woven in a square or hexagonal net form by twisting wires are assembled into boxes and filled with 100mm to 200mm stones in the space. It is a structure used to protect slopes (surfaces), dams, flood protection, and breakwater protection systems of dam river structures.

Such gebion has excellent durability and drainage as well as excellent stability. In particular, the back drainage such as the retaining wall becomes natural drainage between the stones, which are the space filling material, and thus the accumulation of water pressure generated inside the wall does not occur, thereby preventing the risk of collapse.

Since the gebion wall 204 formed by stacking such gebions has a very excellent drainage performance with its own internal voids, there are almost no obstacles to rainwater flow due to a large amount of earth and sand during heavy rains. In addition, considering the site conditions, it is also possible to induce faster collection by installing a pipe inside the gabion. Here, it is preferable that the water permeability coefficient of gebion becomes about 0.8 m / sec.

Inside the storage tank 106a, the earth and sand suppression wall 106b which enters from a floor at predetermined height is provided.

Soils and suspended matter contained in the incoming rainwater are first processed by the gebion wall 204 and secondly removed by using the earth and sand suppression wall 106b in the storage tank 106a, thereby simplifying the cleaning operation in the storage tank 106a. There is an effect that can be achieved.

A discharge pipe 106c for discharging the stored rainwater to the outlet 108 and the discharge conduit 110 is connected to the rear end of the storage tank 106a.

Figure 6 shows another embodiment of the storm runoff reduction system according to the present invention, showing an example applied to the tributary stream and the mainstream stream.

In FIG. 6, the same reference numerals are added to elements that perform the same functions as those illustrated in FIGS. 2 to 5, and detailed description thereof will be omitted.

Referring to FIG. 6, an inlet 304 and a reservoir 106 are shown between the tributary stream 302 and the mainstream 308.

The inlet 304 is a rainwater inlet pipe 304a that provides a rainwater inflow path from the tributary stream 302, and is installed on the rainwater inflow path to block the rainwater inflow path when the floodwater level is lower than that of the tributary stream. If the water level of the 302 is above the flooding risk level, the rubber beam 304b for opening the rainwater inflow path, and the inflow tank 304c for filtering the soil and floats contained in the rainwater flowing through the rainwater inflow pipe 304a. Include.

Since the rubber beam 304b is installed on the rainwater inflow path provided by the rainwater inflow pipe 304a, the cross-sectional shape of the rainwater inflow pipe 304a preferably matches the cross-sectional shape of the rubber beam 304b. In the present invention, the rain inlet pipe 304a has a rectangular cross section, but is not limited thereto.

Rainwater inlet pipe (304a) and the rubber beam (304b) may be installed by cutting the upper portion of the river bank as in the usual beam. The configuration and operation of the rubber beam 304b and the inflow tank 304c are the same as those of the rubber beam 104b and the inflow tank 104c shown in FIG.

At the rear end of the storage tank 106a, a discharge pipe 106c and a gate door 106d for discharging the stored rainwater to the main stream 308 are provided.
