As shown in the drawing, the storm drain device 100 includes a manhole 110 having a plurality of holes and a water collecting device 120 and a hole of the manhole 110 provided at one side of the manhole 110. It consists of a plurality of pipes connected to.

The manhole 110 is a place where the thickness or direction of a pipe is usually changed, a starting point or an intersection point, a middle of a long straight part, etc., and a place where the rainwater can be temporarily stored. The material is usually concrete, and the shape is circular, Square and elliptical.

The rainwater inlet hole 111, which is a passageway through which rainwater enters at the lower end of one side of the manhole 110, and the rainwater outlet hole 112, which is a passageway through which rainwater flows out, are provided.

The rainwater inlet hole 111 refers to the rainwater guide portion entering the manhole 110 from the rainwater inlet pipe 111a in the underground pipe, and the rainwater outlet hole 112 is the next pipe from the manhole 110 in the underground pipe. It says the guide part of the rain-drain pipe | tube 112a.

When the rainwater coming from the rainwater inlet pipe 111a is a proper amount, the rainwater coming from the rainwater inlet pipe 111a fills the bottom of the manhole 110 and fills up to the height of the rainwater outlet hole 112. It is to be discharged to the outside through the 112 and the storm drain pipe (112a).

However, if the rainfall from the storm inlet pipe 111a exceeds an appropriate amount, such as in case of heavy rain, flooding, or rainy season, the rainwater coming from the storm inflow pipe 111a will go out through the storm drain pipe 112a. The flooding of rainwater in the lower regions of the country is feared.

Therefore, the flow rate control device 115 is installed at the inlet of the rainwater outlet hole 112 to adjust the amount of rainwater that goes out to the rainwater outlet pipe 112a. The flow rate control device 115 is a device for controlling the amount of rainwater flowing into the pipe, etc., a member such as an orifice or a vortex valve may be used.

Vortex valve refers to a member for controlling the flow rate is discharged by forming an air column in the center of the fluid when the flow rate exceeds the predetermined flow rate.

The amount of rainwater flowing out through the rainwater discharge pipe 112a by the vortex valve to the outside is maintained below a certain amount, and thus the amount of rainwater flowing into the pipe connected to the manhole 110 can be adjusted to prevent disasters caused by rainwater. It will have a preventable effect.

The flow control vortex valve is a well-known technique by the Republic of Korea registered utility model (registration number: 20-0302157, name of the invention: vortex control valve for flow control), so the detailed description thereof will be omitted.

The flow control device 115 shown in FIG. 5B is a different form from that shown in FIG. 5A, and when the flow control device 115 is used as described above, the inlet of the flow control device is fixed to the bottom of the manhole 110. Even rain accumulated on the bottom of the bottom) can be discharged to the outside of the manhole 110 by the swirl structure formed inside the device.

However, the rainwater that is not leaked to the outside of the manhole 110 by the role of the flow control device 115 is inevitably filled in the manhole 110, and the volume of the manhole 110 is insufficient to store the rainwater. Therefore, a space for temporarily storing the rainwater is needed, and a water collecting device 120 which is the rainwater storage space is provided.

The water collecting device 120 is provided on the side of the manhole 110 to refer to a space for temporary storage by moving the rainwater filled in the manhole 110 to the water collecting device 120 during abnormal weather, such as a heavy rain. The size of the device 120 may be sized according to the amount of rainwater coming in from the storm inlet pipe 111a and the need for abnormal weather signs in the area.

The connection between the manhole 110 and the collecting device 120 is connected through two tubes as shown in Figure 3, the manhole side upper hole 113 provided on the upper part of the manhole 110 is the manhole side upper pipe 123 Is connected to, the manhole side lower hole 114 provided at the bottom of the manhole 110 is connected to the manhole side lower pipe 124, respectively, is connected to the water collecting device.

When the amount of rainwater entering through the rainwater inlet pipe 111a is greater than or equal to a certain amount, only the predetermined amount is discharged through the rainwater outlet pipe provided with the drifting control device 115, and the rainwater is still filled in the manhole 110. The rainwater filled in the interior is moved to the water collecting device 120 through the manhole side upper hole 113 formed on the upper side of the manhole, and the rainwater is continuously collected in the water collecting device 120.

If the amount of rainwater coming from the rainwater inlet pipe 111a decreases, the amount of rainwater in the manhole 110 continues to decrease, and the water in the water collecting device 120 passes through the manhole side lower hole 114 formed below the manhole side. It comes inside.

At this time, the manhole side lower hole 114 is provided with a non-return valve 114a to move rainwater from the water collecting device 120 to the manhole 110, but from the manhole 110 toward the water collecting device 120 It is possible to prevent rainwater from moving. In addition, the non-return valve 114a may be opened when the water pressure received from the water collecting device 120 is higher than the water pressure inside the manhole 110.

Here, the non-return valve refers to a check valve, and means that the fluid flows in only one direction by pressure or the like.

In addition, the inner bottom surface of the water collecting device 120 may be formed to have a gradient so that rainwater is well lowered toward the manhole 110.

Thus, when rainwater enters from the manhole side upper hole 113 and rainwater exits to the manhole 110 into the manhole side lower hole 114, various floats or sludge that may be included in the rainwater are collected in the collecting device 120. Being filtered by the grid pattern provided there is an effect that can prevent the holes (113, 114) blocked by the float or sludge.

The water collecting device 120 is provided in the form of a rectangular parallelepiped in the basement and is configured in a shape surrounding the water collecting block 122 with the water-repellent film 121. The catchment block 122 is configured in the form of a polypropylene rectangular parallelepiped, and the size of the catchment block 122 is preferably provided in the same shape and the same size. The convenience of using a plurality of the catchment blocks 122 is provided. To do this.

First, the excavation of a predetermined area and a predetermined depth is made on the side of the manhole 110, and then the water barrier film 121 is installed at the lower side and the side surface of the excavated area, and the collecting block 122 is disposed on the upper portion of the water barrier film 121. Position it.

However, if the rainwater entering from the manhole 110 as well as the drainage of rainwater transmitted from the top of the water collecting device 120 is required according to the characteristics of the place where the rainwater collecting device 100 is provided, the upper portion of the water blocking film 121 is required. It is also possible to be provided with the material of the permeable material.

And when the rainwater that enters the water collecting device 120, the characteristics of the place where the rainwater collecting device 100 is provided does not necessarily need to move to the pipe through the rainwater outlet pipe (112a) after passing through the manhole (110). It is also possible to be provided with a water-permeable material on the side and bottom of the water-repellent film 121.

A collecting block 122 is provided inside the order film 121. The collecting block 122 should be provided with a support structure sufficient to withstand the pressure from the upper or side portion at the same time to enable a large amount of water collection therein. Therefore, the collecting block 122 is provided in a rectangular parallelepiped structure, but the outside of the collecting block 122 has a lattice structure 122a or a shape 122a having a diagonal shape in the lattice structure, but the catchment volume is 95% or more of the total volume. This is preferred. Here, the total volume refers to the volume of the collecting block 122 that is wrapped by the order film 121.

The collecting block 122 is in the form of a rectangular parallelepiped, each side of which is provided in the form of a small hole having a diagonal shape in the lattice or lattice as described above, but the inside is provided in a mostly empty state. However, if all of the interior is provided in an empty state is weak from the pressure from the top can form a plurality of pillars connecting the upper and lower portions of the block 122 can be added to the robustness. By the above method it can withstand a load of about 33.67 tons / m ^{2 at} the top.

However, when the lattice pattern and the like are formed on each side of the collecting block 122, it is difficult to smoothly exchange the rainwater through the pipe that is the connection part with the manhole, so that two opposite sides of the block 122 are opposite. The central portion of the manhole side upper pipe 123 connected from the manhole side upper hole 113 provided on top of the manhole 110 is preferably provided in an open form without a grid pattern or the like. In order to be connected to the opening (122b) of the rainwater to move smoothly to the water collecting device (120).

The opening part 122b is divided into an upper end and a lower end. As the upper end of the opening part 122b is configured to be opened for the same reason as above, the reason why the lower part of the opening part 122b is configured as an opening part is a catchment. The rainwater collected in the device 120 to move smoothly into the manhole 110 through the manhole side lower pipe 124 and the manhole side lower hole 114 of the manhole 110 from the water collecting device 120 For sake.

At this time, the manhole side upper hole 113 may be connected to the upper end of the opening of the water collecting device, and the manhole side lower hole 114 may be connected to the lower end of the opening of the water collecting device.

And the manhole side lower hole 114 is not provided with a non-return valve as shown in FIG. 3 when the rainwater coming from the rainwater inlet pipe 111 is a certain amount or more, the predetermined amount of rainwater flows out through the rainwater outlet pipe 112 to the outside It is possible, but a certain amount or more of the rain can be moved to the water collecting device through the manhole side lower hole 114.

At this time, the manhole side upper hole 113 can serve as a movement passage of air for smooth movement between the rainwater manhole and the water collecting device. That is, it is possible to smoothly move the rainwater to the manhole 110 and the collecting device 120 by supplying air to the manhole 110 and the collecting device 120 through the hole of the manhole connected to the upper manhole. .
