In addition, the first opening and closing plate 20 and the second opening and closing plate 30 are buoyant to automatically close when the internal water level of the first and second excellent soil chamber 21 and the second excellent soil chamber 31 is increased due to the continuous inflow of initial excellent water. It is a structure containing (B) further. This structure is to block the inflow of the initial excellent water when the internal water level of the first excellent soil chamber 21 and the second excellent soil chamber 31 is increased due to the continuous inflow of the initial excellent rain.

In addition, the first excellent soil chamber 21 is connected through the tea house conduit 60 and the first connecting pipe 22 so that the introduced sewage and initial rainwater can be led to the sewage treatment plant.

In addition, the storage tank 40 is in communication with the second excellent soil chamber 31 and temporarily stores the sewage and the initial excellent water to prevent the discharge of the untreated initial rainwater to the stream beyond the maximum treatment capacity of the sewage treatment plant. do.

The storage tank 40 is provided with a strain screen 421 for preventing the inflow of foreign matter at the connection point with the second excellent soil chamber 31 can prevent the entry of contaminants into the storage tank (40). .

In addition, the storage tank 40 includes a first check opening 41 and a second check opening 42 exposed to the ground. Here, the first inspection opening 41 is for cleaning the inside of the storage tank 40 or for maintenance of the third opening and closing plate 43 provided therein, and the second inspection opening 42 is provided on a vertical line of the trap mesh 421. It is provided to remove the filth collected in the strainer 421.

In addition, a third opening and closing plate 43 is installed in the buoyancy chamber 431 formed at one point of the bottom surface of the storage tank 40 to temporarily store or discharge the sewage and initial excellent water stored in the storage tank 40. to be.

In this case, the buoyancy chamber 431 is connected to the collection pipe 60 through the second connecting pipe 432, wherein the bottom surface of the buoyancy chamber 431 is 1/3 to 2/3 of the collection pipe 60 It is formed at the height of is configured to automatically discharge the sewage and initial excellent water to the house conduit 60 by its own weight.

On the other hand, the third opening and closing plate 43 installed in the buoyancy chamber 431 is also configured to further include a buoyancy cylinder (B) on the bottom. This increases the water level in the rain collector conduit 60 in the rainy weather through the second connecting pipe 432 to increase the internal water level of the buoyancy chamber 431, so that the third opening and closing plate 43 is closed by buoyancy. To do so.

Therefore, when the house conduit 60 becomes full, the first opening and closing plate 20 and the third opening and closing plate 43 are closed, and through the second excellent soil chamber 31 through the second opening and closing plate 30, the storage tank ( A structure in which the sewage and the initial rainwater can be stored in the inside of 40) is prepared.

At this time, the water pressure preventing means 50 further includes a water inlet control plate 52 coupled to the opening 511 so as to control the water inflow amount into the cover housing 51.

In addition, the water inlet control plate 52 is coupled to the opening 511 of the cover housing 51 by forming a long groove 521 on both sides so that the coupling height is adjusted.

Therefore, according to the opening degree of the water inlet control plate 52, by controlling the discharge time of the sewage and the initial excellent by the drainage conduit (60) is a structure that can be discharged for a long time below the maximum treatment capacity of the sewage terminal treatment plant Prepared.

Here, it is possible to prevent the problem that the initial rainwater is not purified and discharged to the river due to the excess of the maximum treatment capacity of the sewage terminal treatment plant by reducing the amount of the initial rainwater flowing into the collecting pipe 60.

Referring to the function of the hydraulic pressure preventing means as follows.

As the buoyancy chamber 431 becomes full, the third opening and closing plate 43 installed in the buoyancy chamber 431 is closed by buoyancy. Then, the air accommodated in the lid housing 51 does not escape to the outside and stays on the lid housing 51 (shown in FIGS. 6 and 7).

Thereafter, even if sewage and initial rainwater are stored in the storage tank 40, the inside of the lid housing 51 is stored only as much as the water level of the opening 511.

Therefore, the inside of the lid housing 51 is not affected by the water level of the storage tank 40 by the received air.

After that, when the water level of the buoyancy chamber 431 is lowered, since the third opening and closing plate 43 is not affected by the water pressure of the storage tank 40, it is easily opened by the weight of the weight.

Thus, when the third opening and closing plate 43 is opened, the stored wastewater and the initial excellent water of the storage tank 40 are adjusted according to the coupling height of the water inlet control plate 52 of the lid housing 51, so that the opening area of the opening 511 is adjusted. It is possible to delay discharge of sewage and initial excellent water to the house conduit 60 over a long time.

In addition, since the sewage and initial rainwater do not rapidly enter the inside of the cover housing 51 due to the opening 511, the third opening and closing plate 43 may be prevented from being closed by the amount of the sewage and the initial rainwater flowing in. Will be.
