In addition, the screen unit 1 includes a sediment separation unit 1111 . The sediment separation part 1111 forms a space for sedimentation separation in the lower part of the hollow part 111 . The sedimentation separator 1111 may induce solid materials with a large specific gravity such as sand and gravel having a large particle size among the rainwater introduced through the rainwater inlet pipe 2 to be precipitated (separated from the inflow rainwater).

That is, according to the screen unit 1 of the present application, the solid material having a large specific gravity of rainwater introduced into the body 11 through the rainwater inlet pipe 2 may be precipitated and accumulated in the sedimentation separation unit 1111, and the specific gravity is At least a portion of the rainwater from which the large solid material is separated may be moved to the storage unit 2 to be described later through the rainwater inlet pipe 3 .

For reference, for example, the body 11 may be provided in a precast concrete (PC) structure, and since the precast concrete (PC) structure is pre-fabricated in a factory, it is possible to shorten the construction period compared to the in-situ method. Since it is not affected by the external environment, it has the advantage that construction can be carried out even in the rainy season or winter season. However, the manufacturing method of the body 11 is not limited thereto, and may be manufactured (constructed) by various manufacturing methods in consideration of construction conditions and the like.

In addition, the filtration unit 121 may be provided so that rainwater flows into the filtration unit 121 through the plurality of filtration holes 1211 .

The plurality of filtration holes 1211 may be formed to have a size to separate (remove) at least some of the foreign substances introduced together with the introduced rainwater. For example, the size of the filtration hole 1211 is determined by the level of inflow rainwater (inflow rainwater, the amount of rainwater to be treated through the system of the present application, and the type and size of foreign substances included in the inflow rainwater), as described above. It may be set in consideration of the size of the particles to be separated by the sedimentation separation unit 1111, and the like. Illustratively, the hole size of the filtering hole 1211 may be about 5 mm, but is not limited thereto.

Rainwater filtered with foreign substances may be introduced into the permeation-type reservoir 4 through the rainwater outlet pipe 3, and at least a portion of the rainwater moved into the permeation-type reservoir 4 is temporarily stored and then gradually penetrates underground. and some may be moved to the auxiliary reservoir 5 through the rainwater transfer pipe 6 . For example, when the rainfall is large, the amount of rainwater flowing into the infiltration reservoir 4 may be greater than the amount of rainwater infiltrating underground from the infiltration reservoir 4, and in this case, the infiltration reservoir 4 The amount of rainwater stored therein increases (the water level increases), and some of the rainwater in the infiltration type storage 4 may be moved to the auxiliary storage 5 through the rainwater transfer pipe 6 .

Rainwater introduced into the auxiliary storage unit 5 may penetrate underground or be discharged to the outside to be used separately.

For example, if rainwater to the auxiliary reservoir 5 continues due to a large amount of rainfall, the amount of rainwater in the auxiliary housing 52 of the auxiliary storage 5 increases (water level increases), and the load (self-weight) of the auxiliary housing 52 increases. may increase, and accordingly, elastic compression of the elastic portion 55 occurs and the auxiliary housing 52 may descend with respect to the main housing 51 , and the auxiliary housing 52 may descend above a predetermined height (elastic portion). When (55) is compressed by more than a preset compression amount), the communication between the first rainwater penetration hole 512 and the second rainwater penetration hole 511 is made, and the penetration of rainwater into the ground can be made. In this way, the auxiliary storage unit 5 serves to infiltrate additional underground rainwater when the rainfall is large (eg, rainy season, etc.), thereby increasing the rainwater penetration (rainwater digestibility) of this infiltration type rainwater storage tank. have. For reference, as described above, since the penetration sheet portion is provided on the lower outer surface of the side surface of the main housing 51 , when the first rainwater penetration hole 512 and the second rainwater penetration hole 511 communicate with each other Rainwater retention (temporary storage) is made and rainwater can penetrate into the ground.

Existing rainwater storage and penetration systems are mostly systems capable of small-scale (small-capacity) treatment, and have limitations in large-capacity rainwater treatment. Accordingly, when a large amount of rain falls for a short period of time such as torrential rain or heavy rain, a rainwater storage and penetration system focusing on disaster prevention purposes such as flood prevention that can effectively store/infiltrate large-capacity rainwater that overflows within a short time ( The development and improvement of the rainwater permeation type storage system) was required. In this infiltration type rainwater storage tank, when large-capacity rainwater overflowing in a short time occurs, rainwater can be penetrated by the auxiliary storage unit 5, so it can effectively store/infiltrate even large-capacity rainwater that overflows in a short time. .

In addition, when the amount of rainwater flowing into the auxiliary housing 52 is such that the elastic part 55 is not compressed more than a preset compression amount, the rainwater introduced into the auxiliary housing 52 is accommodated in the auxiliary housing 52 , It may be stored for separate use, and if necessary, at least a portion of the stored rainwater may be discharged to the outside through the rainwater discharge pipe 54 by the power of the pump 53 .

In addition, a portion of the rainwater discharge pipe 54 inserted into the main housing 51 may be vertically extended. Considering this point, the auxiliary storage unit 5 may be located at a lower height than the permeation type storage unit 4 .

Also, referring to FIG. 4 , a portion located in the second inlet hole 511 of the rainwater transfer pipe 52 may be fixed to the second inlet hole 511 , and the outer surface of the rainwater transfer pipe 52 and the second inlet A sealing may be formed between the holes 511 . In addition, the portion located in the third inlet hole 521 of the rainwater transfer pipe 52 may be fixed to the third inlet hole 521 , and between the outer surface of the rainwater transfer pipe 52 and the third inlet hole 521 . Sealing may take place. In this case, at least a portion of the portion located between the second inlet hole 511 and the third inlet hole 51 of the rainwater moving pipe 52 is a corrugated pipe so that it can be extended or contracted according to the vertical movement of the auxiliary housing 52 . can be formed. Accordingly, referring to FIGS. 4 and 5 together, when the auxiliary housing 52 is lowered, the portion positioned between the second inlet hole 511 and the third inlet hole 521 of the rainwater moving pipe 52 is folded. These can be stretched and stretched, and when the auxiliary housing 52 is raised and lowered, the unfolded portion of the portion positioned between the second inlet hole 511 and the third inlet hole 521 of the rainwater moving pipe 52 is folded. and can be reduced.

In addition, referring to FIG. 4 , the portion located in the second outlet hole 513 of the rainwater discharge pipe 54 may be fixed to the second outlet hole 513 , and the outer surface of the rainwater outlet pipe 54 and the second outlet A sealing may be formed between the holes 513 . In addition, the portion located in the third outlet hole 523 of the rainwater outlet pipe 54 may be fixed to the third outlet hole 523, and between the outer surface of the rainwater outlet pipe 54 and the third outlet hole 523 Sealing may take place. In this case, at least a portion of the portion located between the second outlet hole 513 and the third outlet hole 523 of the rainwater discharge pipe 54 is a corrugated pipe so as to be expandable or contracted according to the vertical movement of the auxiliary housing 52 . can be formed. Accordingly, referring to FIGS. 4 and 5 together, when the auxiliary housing 52 is lowered, the portion positioned between the second outlet hole 513 and the third outlet hole 523 of the rainwater discharge pipe 54 is folded. It can be stretched and stretched, and when the auxiliary housing 52 is raised and lowered, the unfolded portion of the portion located between the second outlet hole 513 and the third outlet hole 523 of the rainwater discharge pipe 54 is folded. and can be reduced.
