The prevention plate 122 prevents rainwater and earth and sand from flowing directly into the rainwater tosoil 170 so as to be led to the earth and sand deposit 140. The earth and sand depositing unit 140 has an inclined surface 142 disposed in a direction opposite to the prevention plate 122 to deposit only the earth and sand among the rainwater and the earth and sand introduced. And the soil depositing portion 140 is provided with a barrier film 144, to reverse the flow of rainwater introduced by the preventive plate 122 to smoothly flow into the rainwater soil chamber 170.

Therefore, the rainwater inflow and earth and sand separation apparatus 100 according to the present embodiment is effective in that the earth and sand flow into the rainwater soil chamber 170 by a simple structure including the prevention plate 122, the inclined surface 142 and the barrier film 144. It can prevent the inflow and smooth the inflow of rainwater.

The soil inflow prevention part 120 includes a prevention plate 122, a height adjusting support member 124, and an inflow screen 126.

The prevention plate 122 is a plate disposed with a constant inclination angle (first inclination angle) with respect to the inflow direction of the rainwater and the earth and sand, and is located on the upper portion of the rainwater discharge chamber 170. As can be seen in Figure 2, one end of the prevention plate 122 is coupled by the upper end and the hinge coupling 123 of the rainwater toil 170, the other end is supported by the support member 124 is a constant height It is deployed with Therefore, the rainwater and earth and sand flowing in the rainwater soil chamber 170 flows in the direction of the earth and sand deposit portion 140 while passing through the prevention plate 122 without being directly introduced into the rainwater soil chamber 170 by the prevention plate 122. I will go.

One end of the prevention plate 122 may be rotatably coupled to the upper end of the rainstorm chamber 170 or a different bottom surface from the rainstorm chamber 170 by the hinge coupling 123. And the height of the support member 124 which supports the other end of the prevention plate 122 can be changed, and the 1st inclination angle of the prevention plate 122 can be changed as needed.

The prevention plate 122 has a rectangular shape corresponding to the inlet shape of the rainwater tosoil 170, and may be formed of a material having high rigidity such as stainless steel. In addition, the prevention plate 122 may be configured as one to cover the entire width direction of the inlet to rainwater chamber 170 or a plurality may be arranged in parallel.

The inclination angle and the like of the prevention plate 122 may be adjusted to smoothly flow in the rain of 3Q during rain.

The support member 124 has a constant height so that the other end of the prevention plate 122 has a constant height. Therefore, the prevention plate 122 is inclined by the support member 124 with the first inclination angle. 3 and 4, a plurality of support members 124 may be disposed along the length of the prevention plate 122, and may be formed of a high rigidity material such as stainless steel such as the prevention plate 122.

The inclined surface 142 corresponds to a portion disposed at one side of the upper inlet of the rainwater discharge chamber 170 having a second inclination angle opposite to the first inclination angle of the prevention plate 122. Therefore, since the inclined surface 142 is disposed to be inclined downward from one side (left side in FIG. 2) of the storm soil 170, among rainwater and earth and sand not directly introduced into the storm soil 170 by the prevention plate 122, As a result, it plays a role of depositing heavy soil.

The inclined surface 142 is formed with a blocking film 144 having a constant height. The blocking film 144 prevents rainwater and soil from flowing through the prevention plate 122 from leaking to the outside, and changes the flow of rainwater to flow into the rainwater soil chamber 170.

The inclined surface 142 may be formed by a separate plate, such as the prevention plate 122, or may be implemented by inclining the bottom surface of the rainwater inflow passage. If the second inclination angle of the inclined surface 142 is made too small so that the inclined surface 142 becomes horizontal, the amount of soil deposited in front of the barrier layer 144 decreases and the amount of soil introduced into the storm soil 170 increases. Done. In addition, when the second inclination angle of the inclined surface 142 is made too large so that the inclined surface 142 is close to the vertical, the inflow of the rainwater into the stormy soil 170 is not smooth. Therefore, the second inclination angle of the inclined surface 142 may be determined in consideration of the amount of rainwater flowing in.

The blocking film 144 corresponds to a film disposed at a predetermined height on the inclined surface 142. Rainfall and earth and sand have passed through the blocking plate 122 to the blocking film 144, due to which the flow of rainwater is changed in the opposite direction, the soil is deposited on the inclined surface 142. And the blocking film 144 also serves to prevent the rainwater and earth and sand that has passed through the prevention plate 122 to the outside.

The blocking film 144 includes a fixed film 146 and a detachable film 148 detachably coupled to the center of the fixed film 146. The fixed membrane 146 is a portion fixed to the inclined surface 142 is provided with a left and right pair. The detachable membrane 148 is detachably coupled to the center of the fixed membrane 146 and may be removed if necessary. The detachable film 148 of the blocking film 144 may be removed to remove soil, rainwater, and the like remaining on the inclined surface 142.

One end of the cleaning cleaning pipe 152 is connected to the inclined surface 142, and the other end of the cleaning cleaning pipe 152 is connected to the rainwater soil chamber 170. One end of the cleaning pipe 152 may be opened or closed by a lid 154. In order to clean the inclined surface 142 and the barrier layer 144 with water or to remove the residues (cold matter) remaining on the inclined surface 142, the lid 154 may be opened to discharge the water into the rain furnace chamber.

Rainwater or wastewater and the like introduced into the stormwater chamber 170 is introduced into the sewage pipe (not shown) via the wear portion 174.

3 and 5, in front of the stormwater chamber 170, a screen 172 including a plurality of rods is provided. The screen 172 has a structure in which a plurality of rods are arranged at regular intervals, and serves to filter foreign matter contained in rainwater or wastewater.
