The present invention relates to stormwater sewage of combined sewage, and more particularly, to uniformly control the flow rate collected to the sewage treatment plant during rainfall, to prevent orifice occlusion and sedimentation of stormwater in the drainage connection pipe, The present invention relates to stormwater silos that can filter out suspended solids and reduce pollution loads into discharged waters.

In general, sewage or wastewater or rainwater generated in homes and factories is collected by a drainage facility through an indoor pipe as shown in FIG. 1 and connected to a combined public sewer (10), and the contaminated sewage (10) is (20) is installed between the tea house (30) is a certain amount or more during the rainfall is discharged to the river, etc., the tea house (30) is connected to the sewage end treatment plant (40) from the storm water chamber (20) connecting pipe ( 21) is sent to the sewage treatment plant 40, the sewage introduced into the sewage treatment plant 40, the treated water is discharged to the stream and the like.

Here, the rainwater soil refers to a facility for collecting a certain amount of sewage in rainy weather at the confluence of sewage and transporting it to a sewage treatment plant and discharging the remaining sewage into water such as rivers. In other words, in the combined sewer, all the sewage is collected in Cheongcheon, but when a large amount of rainwater flows in, such as rainy weather, a large amount of rainwater is collected and sent to the sewage treatment plant, which increases the construction and maintenance costs of the treatment plant. It is uneconomical due to large diameter conduit. Therefore, if the amount of sewage planned for each discharge area reaches the planned amount of sewage (3 times the maximum maximum amount of time) during rainy weather, more rainwater is required to be installed so that it can flow to the discharge stream. Such a structure is called storm silt.

The combined sewage pipe is a conduit that transfers rainwater and sewage together to the sewage treatment plant. In general, it is preferable to treat all the sewage that has been transferred. However, since there is a large amount of surface runoff during rainfall, It is uneconomical to build, so it is designed to house only a few.

Thus, rainwater sediment is installed at the front end of the collecting pipe so that more than a certain amount of water is controlled so as not to flow into the collecting pipe.

To this end, the stormwater inlet is connected to the sewage inlet and the stormwater inlet, and at one side of the drainage pipe, a connection pipe is connected to the sewer pipe, and a monthly wearware is installed on the bottom surface, so that the sewage corresponding to the amount of tea is drained. The rainwater collected after collecting through the ware and entering through the conduit through the connecting pipe and overflowing the overflowware is immediately discharged to the river.

As such, rainwater toss converts only the drainage capacity of the drainage to the treatment plant and overflows the amount of drainage in the rainy season. Due to problems such as the accumulation of sediments, it was frequently overflowed into the discharge area during rainfall, and in the dry season, there were frequent cases of overflowing from some stormwater due to the blockage of the orifice in the conduit.

In addition, if the flow rate gradually increases during the rainfall and exceeds the water flow capacity of the collection pipe transported to the sewage treatment plant, the uncollected flow rate overflows into the discharge water through the storm drain. Since the combined sewer overflows include basin sewage as well as rainfall runoff, it contains various contaminants such as soil, hair, wrapping paper, food waste, and wood chips.

Therefore, it is possible to prevent sedimentation and orifice blockage of stormwater, and to control the fluctuation of the inflow flow that seriously affects the performance of the sewage treatment plant during rainfall, to ensure stable operation of the sewage treatment plant, and to There is an urgent need to develop technologies that can effectively control pollutants.

Still another object of the present invention is to provide an excellent soil chamber capable of filtering foreign matters such as soil, contaminants, and floating substances contained in the overflowed water of the combined sewage pipe.

Still another object of the present invention is to provide an excellent soil silo to prevent clogging of the screen by easily removing the contaminants on the screen.

In order to achieve the object as described above, the present invention has a structure in which a buoyant sluice part is installed to control the degree of opening of the connection pipe as the flow rate increases in the connection pipe connecting the rainwater soil and the collecting pipe.

To this end, the buoyancy gate portion is the frame structure installed in the connecting pipe, the orifice installed on the frame structure, the blocking plate which is rotatably installed in the front of the frame structure to adjust the opening amount of the orifice according to the degree of rotation, It is installed on one side of the blocking plate and includes a support body to support the water.

Accordingly, when the amount of sewage flowing into the rainwater chamber is increased, the float is floated on the water, and the blocking plate installed with the float is rotated to block the orifice to adjust the cross-sectional area of the orifice, and accordingly, the flow rate of sewage collected through the connecting pipe is fixed. I can keep it.

In this case, the buoyancy gate portion may be further provided with a stopper member to be caught by the side of the blocking plate on the front of the frame structure to control the angle of rotation of the blocking plate.

In addition, in the form of the said blocking plate, if it is a structure which cuts off an orifice so that the collection flow volume at the time of rotation according to an increase in flow volume may be maintained, it will not specifically limit in the form.

On the other hand, the present invention may further include a flow control unit is installed in the front end of the flotation sluice to increase the flow rate of the sewage flow into the rainwater chamber.

The flow control part may be formed on an inner side surface of the rainwater toil and may be formed of an inner wall for reducing the cross-sectional area of the rainwater tosoil.

The inner wall may be formed on one side of the inner both sides of the urethane soil or toward the center on both sides.

A portion of 61 is blocked to reduce the cross-sectional area of orifice 61.

As the cross-sectional area of the orifice 61 is reduced in this way, the amount of sewage flowing through the orifice 61 is reduced, so that only the planned collection amount can be collected regardless of the amount of sewage flowing into the storm drain 20. .

On the other hand, when the flow rate increases due to the rainfall exceeds the water flow capacity of the collecting conduit 30, the sewage is discharged beyond the overflow wear 22 in the storm water chamber (20).

In this process, the overflow water over the overflow wear 22 passes through the screen for treating the overflow water installed on the overflow wear 22, and the sewage, contaminants or floating foreign matters contained in the overflow flow are filtered out. Will reduce the load of contamination.

In addition, the overflow water treatment screen 70 is continuously cleaned by the rake 86 to prevent the screen from being blocked.

Looking at the screen cleaning process in more detail, the overflow water flowing over the overflowware 22 falls from the overflowware 22 and hit the wings 91 of the windmill 90 installed behind the overflowware 22 windmill ( 90) is rotated.

As the windmill 90 is rotated, the drive sprocket wheel 92 installed on the shaft of the windmill 90 rotates, and the driven sprocket wheel 93 connected to the drive sprocket wheel 92 via a chain 94 acts as a power source. It receives and rotates.

Here, the driven sprocket wheel 93 is installed at the tip of the lower rotation shaft 81 so that the rotational force of the windmill 90 is finally transmitted to the lower rotation shaft to rotate the lower rotation shaft 81.

As the lower rotation shaft 81 is rotated, the chain 84 spanning the sprocket wheels 82 and 83 provided at the front end of the lower rotation shaft and the upper rotation shaft 80 rotates in the vertical direction of the screen 70.

Therefore, the connecting bar 85 provided between the chain 84 is moved in accordance with the rotation of the chain 84 to pass through the screen 70 in the vertical direction.

Here, the connecting bar 85 is provided with a rake 86 passing through the diaphragm 71 of the screen 70 so that the connecting bar 85 passes through the screen 70 in the vertical direction. Rake 86 installed in the (85) is to go through the diaphragm 71 of the screen 70 is to remove the foreign matter caught between the diaphragm (71).
