Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present technology will be described in further detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
As shown in the figure, the surface runoff initial rain control structure can be used for collecting initial rain water and comprises an initial rain water collecting tank 1 and an automatic water isolation device, wherein the initial rain water collecting tank comprises a water inlet 11 and a permeable paving structure, and rain water enters the initial rain water collecting tank 1 through the water inlet and can infiltrate into the ground through the permeable paving structure; the primary rain collecting tank is provided with an automatic water isolation device at the water inlet, the automatic water isolation device can be automatically closed in the state that the primary rain collecting tank is full of water, and a continuous small-flow water supplementing channel is arranged in the closed state, so that the water supplementing flow of the water supplementing channel and the water seepage quantity of the primary rain collecting tank can be kept in dynamic balance.
Specifically, the water inlet 11 of the first rain collecting tank 1 is arranged at the downstream of the rain gutter 2 and is communicated with the rain gutter 2, and is further arranged at the bottom of the rain gutter 2, and the automatic water isolation device is a floating plate 3 which is arranged at the water inlet and can rotate up and down. The floating plate 3 is provided with a rotating shaft 31, the profile of the floating plate 31 is consistent with the profile of the water inlet 11, the floating plate 3 keeps naturally drooping when the initial rain collecting tank 1 is free of water, is jacked up to continuously rotate along with the rising of the water level of the initial rain collecting tank 1, and keeps a horizontal state all the time when the water level of the rain gutter 2 is not lower than the lower surface of the floating plate 3; the horizontal float plate 3 covers the water inlet 11 entirely and allows subsequent stormwater from the stormwater drainage ditch 2 to flow downstream from the top of the float plate 3. When the floating plate 3 is in the horizontal position, the effect of well isolating the rain gutter 2 and the primary rain collecting tank 1 is achieved, the situation that the primary rain which is fully collected in the primary rain collecting tank 1 and polluted seriously exchanges with the subsequent low-pollution-degree rainwater in the rain gutter 2 is effectively avoided, secondary pollution to nearby water bodies is avoided, meanwhile, the effect of stabilizing the rainwater in the primary rain collecting tank 1 is achieved, the phenomenon that the rainwater in the rain gutter 2 severely agitates the rainwater in the primary rain collecting tank 1 is avoided, and further the phenomenon that the pollutants which are precipitated in the primary rain collecting tank 1 are turned over again to influence the precipitation effect is avoided.

When the initial rain collecting tank 1 is empty, except for being communicated with air through the water inlet 11, the rest parts are all closed underground structures. In other embodiments, the primary rain collecting tank 1 may extend to the outside of the rain gutters 2, and the extended portion is located entirely below the ground surface, or may be an open structure.
The invention is applicable to obvious catchment ditches and gully areas at two sides of municipal roads and other areas with serious water and soil loss. The structure is arranged in the downstream area of the groove, the excavation depth and the opening size of the primary rain collecting groove 1 are determined according to the primary rain amount and the rainfall amount required to be collected at the setting place, the opening width is determined according to the width of the on-site drainage ditch, the masonry of the primary rain collecting groove 1 is built or poured by adopting a water seepage material, the floating plate 3 is made of PVC (polyvinyl chloride) plates, the rotating shaft 31 of the floating plate 3 is made of a metal material, the rotating shaft 31 enters the first clamping groove 21 from the second clamping groove 22 so as to finish installation, and the clamping groove is prefabricated on the wall of the cement ditch in advance.
The invention has good control effect on surface runoff formed by initial rainwater, the system adopts water seepage materials, the function of on-line infiltration to the underground is added compared with the traditional cement regulating tank, the groove wall and the groove bottom of the initial rainwater collecting groove 1 are sequentially paved with the crushed stone layer 1c, the coarse sand layer 1b and the water permeable brick 1a from the adjacent soil side to the inner side of the groove, the good water permeable infiltration effect can be achieved, and the system has the characteristic of difficult blockage. And because the water inlet 11 top of this structure has the kickboard 3, can self-closing kickboard 3 after just rain collecting vat 1 has collected enough high contaminated just rain, the rainwater of later stage low pollution degree can be along kickboard 3 downstream to can effectively reduce the pollution that the water body of low reaches especially silt suspended solid caused, play the effect of preventing soil erosion and water loss, avoided secondary pollution.
