Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a retention and management system for preventing flooding of roads,

The present invention relates to a stormwater stormwater management system and, more particularly, to a stormwater stormwater stormwater stormwater stormwater stormwater stormwater stormwater stormwater stormwater stormwater stormwater stormwater stormwater stormwater stormwater stormwater , The groundwater can be prevented from being contaminated by the groundwater because the rainwater is removed from the nonpoint source of stormwater, and some of the stormwater that penetrates into the ground can be stored for various purposes. And an excellent storage and management system for excellent reuse.

As urbanization and industrialization progressed, the area of artificial ground, which is impervious to urban areas, was increased. In urban areas like Seoul, about 70% of the total area was covered with rainwater. The water shortage due to the deterioration is gradually increasing.

In addition, depletion of groundwater in the underground space leads to weakening of the ground, thereby promoting sinkhole formation due to the collapse of the ground, thus causing the collapse of buildings and damage to human life.

Since the stormwater can not penetrate into the ground, stormwater is concentrated in stormwater or drainage, and it can not be drained efficiently, resulting in loss of lives and property due to inundation of the housing.

More specifically, in recent years, rainfall events frequently occur outside the design frequency of internal drainage facilities every summer due to the influence of heavy rain due to climate change in Korea. Especially, in urban areas with high imperviousness, the dependence on storm drains and pumping stations is high, and the occurrence and damage of road flooding due to extreme rainfall are increasing.

In order to solve such a problem, Korean Patent Registration No. 10-0984372 (Registered on September 20, 2010, on the roadside rainwater storage and infiltration facility, hereinafter referred to as "prior art") has been disclosed. The above-mentioned prior art relates to rainwater storages and infiltration facilities on the roadway side, and it can prevent infiltration and flood flooding by rapidly treating pollutants such as roads and reducing the storm drainage load to reduce the rainwater pumping station and the sewage treatment plant load, The present invention relates to a facility for controlling an excellent discharge amount in accordance with a flow rate of an inflowing rainwater into the ground and infiltrating rainwater into the ground.

The rainwater storage and infiltration facility according to the related art is provided with an excellent storage unit buried in the edge of a road and having a plurality of storable storage boxes coupled with storages therein; A rainwater collecting body having an upper portion opened and having at least one rectifying hole communicating with the storerob portion at a peripheral portion thereof and a first outlet hole formed at one side thereof, a grating installed at an upper opening portion of the rainwater collecting body, A baffle which is formed in a plate shape having a second outflow hole smaller than the outflow hole and which is set up at a predetermined interval from the first outflow hole in the rainwater receiver main body, a second outflow hole of the baffle is selectively opened and closed, And valve means for guiding the second outflow hole to be discharged through the first outflow hole by turning or passing through the second outflow hole; An excellent box communicating with the first outlet hole of the rainwater receiver through the connection pipe to store the rainwater introduced into the rainwater receiver; And a rainwater collecting unit installed in the rainwater collecting box or rainwater collecting box of the rainwater collecting unit to penetrate the rainwater collecting unit and rainwater collecting unit.

However, in the prior art, when the initial stormwater is penetrated into the ground, the stormwater must pass through the filter and the oil pipe arranged in the vertical direction. However, since the oil pipe is buried in the ground, it is difficult to quickly discharge the initial stormwater. Therefore, in the case of concentrated rainfall, the amount and rate of penetration of rainwater into the ground through the pipe are relatively small, so that most rainwater should be treated in the rainwater box, so flooding or flooding that has been a problem in the past may still occur.

In addition, in the prior art, only the penetration of rainwater into the ground is made through the pipe. That is, since the rainwater infiltrates into the ground only through the relatively narrow pipe called the oil pipe, it is difficult to penetrate the rainwater evenly at a specific point, and the infiltration rate of rainwater into the ground is lowered .

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide an excellent storage and management system capable of rapidly infiltrating an impervious road with rainwater.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an excellent storage and management system for prevention of road flooding, ground stability through groundwater level maintenance and excellent reuse according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a plan view showing a road using a stormwater storage and management system according to the present invention, FIG. 2 is a sectional view taken along the line AA 'of FIG. 1, FIG. 4 is a perspective view illustrating the construction of a superior receiving apparatus according to the present invention, and FIG. 5 is an exploded perspective view illustrating a construction of a superior receiving apparatus according to the present invention.

As shown in the figure, the stormwater storm management system according to the present invention mainly comprises a stormwater receiver 10, a storm surge unit 20, a water permeable unit 30, a pipe tube 40 and a storage unit 50. An excellent storage / drainage unit 60 buried in a basement of a road (or a railway station) 70 for temporarily storing stormwater and draining the stormwater is also connected to the storm drainage unit 20 and the storage unit 50 However, the present invention is not limited to the configuration in which the stor- age storage / drainage section 60 can be selectively applied as needed.

First of all, the rainwater receiving unit 10 is installed at the edge of the road 70 so that rainwater can be introduced. The superior receiver 10 includes a main body 11, an inlet 12, a filter 13, and a grating 14.

In more detail, the main body 11 has a communication hole 11a, which is open at its upper portion and communicates with the smooth flow portion 20 at its lower portion. The body portion 11 is generally formed in the shape of a rectangular box and is provided at the edge of the road 70 adjacent to the barrier 16, and its upper surface generally coincides with the road surface. The body portion 11 is provided with an inlet 11b for introducing the overflowing rain from the inlet portion 12 into the main body portion 11 at one side portion spaced apart from the body portion 11 and the inlet portion 12 Is formed.

In addition, the inlet 12 is a portion of the storm that has fallen onto the road 70, at least one side thereof facing the road 70 and the upper surface thereof being coincident with or lower than the road surface.

The inlet portion 12 is spaced apart from the lower portion and at least one side portion of the body portion 11, and a plurality of through holes 12a are formed in the side portion and the lower portion. This is to form a structure in which the storm can be introduced into the inflow section 12 and the storm that passes or overflows the inflow section 12 can be introduced from the main body section 11.

The filter 13 is disposed on the side and the bottom of the inflow portion 12 inside the inflow portion 12 so as to filter off the fine contaminants passing through the through-hole 12a. The filter 13 serves to prevent high concentration contaminants contained in the initial rainwater from flowing into the ground. When the filter 13 is contaminated, it is difficult to filter contaminants. Therefore, And the like.

The grating 14 is mounted on the upper portion of the inflow portion 12 to block inflow of relatively large foreign matter such as refuse into the inflow portion 12, (12) functions to prevent accidents such as falling of a person or an animal or a wheel of an automobile.

On the other hand, a drop prevention jaw 15 is provided at one side of the inlet 12 facing the inlet 11b to prevent the suspension from flowing into the inlet 11b. That is, the dropping prevention protrusion 15 is protruded from one side of the inflow part 12 to prevent the floating matter from flowing into the inflow part 12 and being prevented from flowing into the inflow port 11b without being precipitated or filtered. In addition, the drop prevention tongue 15 also increases the level of the overflowing overflow in the inflow section 12, so that a larger amount of initial storm including pollutants is filtered and introduced into the ground.

Since the inlet port 11b communicating with the main body 11 is formed at one side of the inlet 12 in the present invention, the inlet port 11 is formed at one side of the inlet 12, The boundary block 16 is provided with a boundary block 16 having at least a cut-out groove 16a at least at the bottom thereof so as to secure the inlet port 11b. In other words, the barrier 16 protrudes from one side of the main body 11 facing the inlet 11b to the edge of the road 70, And a cutout groove 16a.

The storm reservoir 20 is installed at a lower portion of the stormwater receiver 10 and connected to the communication port 11a of the stormwater receiver 10 and extends horizontally with a space formed therein. That is, the overflow section 20 extends in the longitudinal direction of the road along the edge of the road 70.

Since the space formed in the inside of the storm surge portion 20 allows the stormwater inflow from the stormwater receiver 10 to be impregnated into the ground, it is difficult for a large amount of storm to permeate into the ground at a certain area, And serves as a pathway for dispersing stormwater to other points.

The cross section of the superior flow section 20 is formed in an open bottom shape and may be formed in a rectangular shape, but it is preferably formed in an arcuate shape to favor the proof against the earth pressure from the top.

A support plate 23 is formed at the lower end of the superior flow section 20 to distribute the load and the support plate 23 is seated on the support angle 27. The support angles 27 are provided to prevent sedimentation of the well fluidic portion 20 and are arranged in parallel on the permeable portion 30 to be described below.

A plurality of through holes (21) are formed on the side of the superior flow section (20) to allow the outflow of rainwater. This is for the purpose of enabling drainage of the rainwater through the through hole 21 even when the foreign matter accumulates in the lower part of the storm reservoir 20 and the rainwater becomes difficult to drain to the lower part of the storm reservoir 20.

A drainage pipe 25 is formed at an upper end of the side of the storm hydraulic unit 20 and a drain pipe 61 connected to the storm drainage unit 60 buried in the underground of the road is installed in the drainage hole 25 do. When the amount of increase in the amount of rainfall that is introduced into the submerged floating section 20 is greater than the rate of increase in the amount of rainfall that flows into the submerged flow section 20, the drainage port 25 discharges the stormwater to the storable storm drainage section 60 through the drainage pipe 61 .

The permeable portion 30 is made of a permeable material such as aggregate or gypsum which is permeable to particles between the particles and is stacked on the lower portion of the flowing portion 20. At this time, the permeable material may also be laminated on the permeable portion 30.

The permeable material is buried in the porous pipe 40. The perforated pipe (40) is disposed at a lower portion of the superior flow portion (20) so that a part of the flow discharged into the ground through the superior flow portion (20) can be introduced. The perforated pipe (40) is connected to the storage part (50) and supplies the inflowing storm to the storage part (50).

The storage unit 50 is connected to one end of the pipe 40 so as to store the rainwater flowing into the pipe 40. A drain pipe 61 for discharging the stormwater to the stor- age storage and drainage unit 60 is installed in the storage unit 50 and a pump 51 for pumping the stored stormwater is installed do.

The storm water stored in the storage section 50 can be pumped to the outside by the pump 51 and sprayed from the center separator 80 to cool the heat of summer road surface.

Next, the operation of the stormwater storm management system according to the present invention will be described.

As shown in Fig. 6, the storm that has fallen on the road flows to the edge of the road 70 along the gradient of the road, and flows into the inlet portion 12 of the storm receptacle 10. At this time, the grating 14 is seated on the inflow part 12, so that only foreign matter such as waste does not flow and only the rain comes.

The inflowing storm flows into the main body portion 11 through the through hole 12a of the inflow portion 12. The inflow portion 12 is fitted with the filter 13 and flows into the main body portion 11 The high-concentration contaminants are filtered while passing through the filter (13). The filter 13 may be removed from the inlet 12 and replaced with a new filter because the filter performance is deteriorated due to adsorption of contaminants during long-term use.

If the amount of storm water flowing into the inlet 12 increases beyond the amount of storm water flowing into the main body 11 through the filter 13, the water level of the inlet 12 is increased to overflow 9), and the overflowing storm flows into the main body section 11 through the inlet port 11b of the main body section 11. The storm that overflows does not pass through the filter (13), but the storm that overflows is not the initial storm, so it contains almost no high-concentration contaminants. That is, in the present invention, the initial outflow containing a large amount of the high concentration pollutants flows into the inlet portion 12, flows through the filter 13 and flows into the main body portion 11, So that contamination of the soil by the highly concentrated contaminants can be prevented, and excellent drainage can be achieved.

At this time, a drop preventing jaw 15 is provided on one side of the inflow portion 12 facing the inflow opening 11b to prevent the inflow of the float, and when the inflow portion 12 is not overflowed, .

The cutout groove 16a is formed in a part of the boundary block 16 so that the rainwater overflowing from the inflow section 12 can be smoothly introduced into the inflow port 11b. In order to form the inflow port, (70). That is, even when the barrier 16 is seated on one side of the main body 11, the inlet 11b of the main body 11 is exposed between the main body 11 and the barrier seat 16,

The rainwater flowing into the body portion 11 is discharged to the oil well flow portion 20 through the communication hole 11a of the body portion 11. [ Since the support member 23 is mounted on the support angle 27, the load 20 and the earth pressure on the road 70 can be reduced by the load And the earth pressure can be dispersed and sedimentation is prevented.

The stormwater which has flowed into the storm surge portion 20 penetrates into the ground in the inner space of the storm surge portion 20 and the storm that can not penetrate through the storm surge portion 20 flows along the inner space formed along the longitudinal direction of the storm surge portion 20 It flows into the ground. At this time, since the permeable portion 30 made of the permeable material is disposed at the lower part of the storm surge portion 20, it is easier to penetrate the underwater stormwater.

As shown in FIG. 8, when the amount of stormwater flowing into the storm reservoir 20 increases, it is also discharged through the passage 21 formed in the side of the storm reservoir 20, The waste water is drained to the storable storage and drainage unit 60 via the drainage pipe 61 through the drainage hole 25 formed at the upper end of the side portion as shown in FIG.

As shown in FIG. 7, part of the stormwater flows from the bottom of the storm reservoir 20 to the water puddle portion 30 And is supplied to the storage section 50. [0050]

The storm supplied to the storage section 50 is stored in the storage section 50 and is pumped by the pump 51 to be utilized for various purposes. For example, it can be used for water supply to fire fighting water or roadside water, or for road use in the median 80.

When the stormwater flowing into the storage section 50 increases and the water level of the reservoir section 50 overflows, the water is discharged to the storm drainage section 60 through the drain pipe 61 installed in the storage section 50 do.

The stormwater that has flowed into the stor- age stor- age and drainage section 60 can be temporarily stored and then drained to a river or the like without being temporarily stored.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined by the appended claims. It is obvious that you can do it.
