Technical scheme of the present invention is, a kind of environment-friendly type roads rain inlet, comprise the inner space under rain grate and the road surface, described rain grate had pan, described inner space is divided into small one and large one two parts, large space wherein is between damming, and little space is between overflow, and the volume between damming should be able to satisfy interception and store designed initial stage run-off; Be positioned at the pan bottom between described damming, and be positioned at the rear portion between damming between overflow, boundary is provided with overflow weir between damming and between overflow, and the overflow weir front is provided with baffle plate, on the top board between baffle plate is installed in and dams, with the about 30cm of the horizontal range of overflow weir; The bottom of the wall of close curb one side and the bottom partition wall of overflow weir are permeable wall between damming; Be concrete floor between damming and bottom between overflow, the concrete floor that is positioned at curb one side stretches out the outer 15cm of permeable wall; Outlet pipe is arranged on the bottom between overflow, and the rainwater between overflow is entered the downstream line system.
This technical scheme both had been suitable for the ground rainwater mouth of sub-district, also was suitable for the inlet for stom water of urban road.Can tackle the pollutant more than 80%, significantly reduce the rainwater pollution of area source and enter downstream river course.
Further, for the initial stage runoff of being tackled can be in 24 hours by infiltrating the soil emptying, thereby do not influence the interception of runoff of following rainfall initial stage.
The present invention changes the way of traditional direct-discharging inlet for stom water, grid filtration, initial stage runoff interception and automatic reject, floating thing interception are combined, both tackled the most of pollutant in the surface runoff, guarantee the smooth collection and the discharging of rainwater again, had significant environmental ecological benefit and economic and social benefits.
