Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown below in Figure 1, the sewage and rainwater drainage system according to the present invention is a sewage flow path (a) and rainwater flow path (b, c) formed so that the sewage (arrow A) and rain (arrow B) flows separately, respectively. And a sewage flow path closing portion (d) formed to close the sewage flow path (a), and divide the storm flow paths (b, c) into an initial storm flow path (b) and a continuous storm flow path (c) A drain passage 10 having a storm flow passage partition e formed such that storm water (arrow B) having a predetermined level or more in the storm flow passage b flows into the continuous storm flow passage c; A sewage inlet 20 formed in the drainage path 10 so that sewage (arrow A) flows through the sewage flow path a; It is configured to include; rainwater (arrow B); rainwater inlet 30 formed in the drainage path 10 so that the rainwater (b) can be introduced into the initial rainwater flow path (b).

That is, instead of forming a sewage (arrow A) pipe and an excellent (arrow B) pipe as in the related art, one drainage path 10 is formed at a buried position secured by one excavation operation, but excellent in this. Both the flow paths b and c and the waste water flow path a are included. In particular, since the sewage (arrow A) of the sewage flow path (a) should not be mixed with the rainwater (arrow B), the sewage flow path closing part (d) so that all the top, bottom, left and right sides of the sewage flow path (a) are closed (only the front and rear sides are opened). It is formed.

In addition, in order to separate the initial storm (arrow B) and the continuous storm (arrow B), the storm channel (b, c) includes the initial storm channel (b) and the storm storm channel (c). In other words, rainwater (arrow B) is used for non-point pollution sources (e.g., pollutants accumulated on the top of roads and bridges, fine dust such as vehicle exhaust gas and tires, and roads and agricultural land). With the accumulated pollutants, etc.). Since most of these nonpoint sources are washed by rain within a certain time from the start of the rainfall, that is, the initial storm (arrow B), the initial storm (arrow B) should be treated with contaminated water, such as water purification. The relatively clean non-contaminated water in arrow B) is meaningless to water treatment.

Therefore, the following effects can be obtained.

First, since a plurality of excavation operations are not required for the sewage (arrow A) pipe and the rainwater (arrow B) pipe as in the related art, labor and cost required for construction can be reduced.

Second, in consideration of the characteristic that a certain amount of sewage (arrow A) flows always in the sewage (arrow A) pipeline and rainwater (arrow B) flows only in the rainwater (arrow B) pipeline, the overall drainage path 10 Larger sizes are formed (conventionally, two pipelines are combined), and a sewage flow path (a) having a size necessary for only a part of the area is formed, so that an excellent rainfall path (b, c) of sufficient size can be secured, and heavy rain Reduces damage from flooding of city storms (arrow B).

Third, the rainwater passages b and c can freely enter and exit unlike the conventional sewage pipes, and enter the rainwater passages b and c to facilitate the maintenance work of the wastewater passage a.

Fourth, since only the initial rainwater (arrow B) needs to be treated with water, it is possible to prevent overload during water treatment. That is, when the rainfall starts, the load of rainwater (arrow B) is not large at first. If it persists, superior (arrow B), ie, sustained superiority (arrow B) flows into the continuous superior flow path (c) and flows directly into the continuous superior flow path (c), thereby separating the initial excellent (arrow B) and the sustained excellent (arrow B) simply and reliably. Thus, only the initial rainwater (arrow B) can be treated with water.

The drainage passage 10 may form the sewage flow passage closing part d in any configuration, but a plurality of precast boxes 10a having a front and rear opening are mutually connected in the front and rear directions. As an example, an embodiment of the present invention will be described.

The sewage flow passage (a), the initial storm flow channel (b), and the continuous storm flow channel (c) may be arranged in various structures. However, the sewage flow path (a) is formed on at least one edge of the left and right sides of the drainage path (10), and the sewage flow path (a) and the continuous rainwater flow path (c) are formed side by side, and the sewage flow path (a) An initial rain channel (b) may be formed on the upper side.

Accordingly, both the sewage inlet 20 and the rainwater inlet 30 may be formed on the left and right sides of the drainage path 10, respectively, so that the sewage inlet 20 and the rainwater inlet 30 are not complicated. Can be formed. In addition, as the initial storm channel (b) is disposed above the wastewater channel (a), the continuous storm channel (c) may be formed deeper than the initial storm channel (b) by the depth of the drain channel (a). It is possible for stormwater (arrow B) to overflow from the initial storm channel (b) to the sustained storm channel (c), but if there is not too much rainfall, such as during a flood, without further action, Overflow can be prevented by the initial rain runoff (b).

In the case of the flow path arrangement structure as shown in the figure, the rainwater flow path partition part d simply consists of the partition wall 200 protruding above the sewage flow path closing part d. The flow path b and the sustained storm path c can be separated.

Further, the partition wall 200 may be formed with a rainwater inlet hole 202 so that the rainwater (arrow B) can be introduced into the continuous rainwater flow path (c) from the initial rainwater flow path (b). In particular, the rainwater inlet 202 may be equipped with a filter 210 to filter the initial rainwater (arrow B) by filtering the nonpoint source contained in the initial rainwater (arrow B).

In addition, when the rainfall continues and the water level rises so that the partition wall 200 does not overload the filter 210, the rainwater (arrow B) flows over the partition wall 200 so that the rainwater flow path lasts in the initial rainwater flow passage b. It may be formed at a predetermined height to have a predetermined distance (G) and the upper surface of the drainage path 10 so that it can be introduced directly to (c).

The sewage flow path closing part (d) is preferably in view of convenience of construction so that a plurality of sewage flow path closing members 100 are interconnected in the front and rear directions.

Specifically, the sewage flow path closing member 100 includes a side closure part 110 having a lower end coupled to a bottom surface of the drainage path 10 so as to close the side of the sewage flow path a; And an upper closure part 120 extending laterally from an upper end of the side closure part 110 so as to close the upper side of the sewage flow path a, and having a side end coupled to an inner side surface of the drainage path 10. The sewage flow path closing part d is formed by the side closure part 110, the upper closure part 120, and the bottom and the inner side surface of the drainage path 10. It is preferable at the point which can be formed.

The sewage passage closing member 100 may have a structure formed to be bent or curved.

When the rainwater inlet hole 121 is formed through the upper closure portion 120 of the wastewater passage closing member 100, a part of the rainwater (arrow B) blown during a heavy rain flows through the stormwater inlet hole 121. It may be introduced into a), in which case the introduced rainwater (arrow B) will naturally clean the sewage flow path (a), which is preferable in terms of maintenance.

However, in order to prevent large contaminants due to heavy rain from flowing into the sewage flow path (a), it is preferable that the filter inlet hole 121 is equipped with a filter 121a.

The drainage system according to the present invention may be implemented by a new installation, but may also be implemented by a method (repair) of installing a sewage flow path closing member 100 in an existing rainwater pipe.

A coupling protrusion 122 is formed upward at a side end of the upper closure portion 120 of the sewage passage closing member 100, and the coupling protrusion 122 is formed in the drainage path 10 by a coupling mechanism such as an anchor. It may take a configuration to engage the side.

In addition, a coupling protrusion 112 is formed at the lower end of the side closure portion 110 of the sewage passage closing member 100, and the coupling protrusion 112 is connected to the bottom surface of the drainage passage 10 by a coupling mechanism. It may take a configuration to combine.

This coupling structure is suitable for implementing the drainage system according to the present invention by the latter method (repair) because it is a structure that can install the sewage flow path closing member 100 with respect to the existing drainage path (10).

The sewage flow path closing member 100 may be formed of a precast concrete material, but may be sufficiently implemented by other materials such as synthetic resin and (waveform) steel sheet.

In the former case, the plurality of sewage passage closing members 100 may be coupled to each other by a method of fixing the PS strand through the fixing unit 101.

In the latter case, the coupling wing portion (not shown) for engaging with the other sewage flow path closing member 100 coupled adjacent to the front and rear ends of the sewage flow path closing member 100 is formed to protrude outward, The sewage flow path closing portion d can be formed by mutual coupling of the dragon blades.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention.
