First, as illustrated in FIG. 5, rainwater of the road surface is introduced into the rainwater inflow path 140 through the inflow hole 112 formed in the cover 110 of the filter channel 100. The introduced rainwater is filled from the sedimentation tank 210 and the bottom surface 150, and the relatively large specific gravity and volume of the foreign matter 400 included in the initial rainwater are stacked on the bottom surface 150.

When the inflow of rainwater is increased, as shown, the rainwater is introduced into the inlet 250 through the filter screen 120, at this time, the foreign matter 400 that did not pass through the filter screen 120 is also the Filtered by the filter screen 120 is laminated on the bottom surface (150).

On the other hand, as shown in Figure 6, when the rainwater inflow is further increased, the water level is gradually increased to the top of the overflow portion 230.

Subsequently, as the stormwater inflow increases, the stormwater barrier 220 flows over the stormwater flow channel 240 as shown in FIG. 7. At this time, the fine foreign matter 400 passing through the filter screen 120 is stacked on the bottom surface of the overflow portion 230, in particular concentrated on the inclined surface connecting the inlet 250 and the settling tank 210.

In addition, the rainwater flowing into the flow channel 240 moves to the destination along the flow channel 240.

On the other hand, the inflow of rainwater is stopped, the state in which only the foreign matter 400 is deposited after the rainwater in the rainwater culvert structure is all drained is shown in FIG. As shown in the drawing, the foreign matter 400 is mostly stacked on the bottom surface 150 according to size and specific gravity, and the remaining part is also deposited on the bottom of the overflow portion 230.
