浅谈城市道路雨水口的改进方法

城市道路上的雨水口,虽然上面都设有篦子,可以防止较大的杂物落入雨水口内,但小于篦子孔径的杂物仍然会落入雨水口内,在雨水口和管道内沉积。不但会造成排水不畅,而且落入雨水口内的杂物在雨水浸泡下腐烂发酵,带有异味的气体外逸污染空气,腐烂发酵物体再经过雨水冲至管道后排入水体,对水体造成污染。该文介绍一种对雨水口的改进方法,它不改动雨水口的结构,只在雨水口内安放一个装置,可以防止雨水口异味外逸、杂物落入。该方法可供同行推广应用。

Elementary Discussion on Improvement Method of Urban Road Rainwater Inlet

The rainwater inlet on the urban road can prevent the larger sundries from falling into the rainwater inlet although there is a fine-toothed double-edged comb on it,however the sundries smaller than the comb aperture will still fall into the rainwater inlet.The sediment in the rainwater inlet and pipeline will not only cause the drainage block,is but also putrid and fermented under the waterlogging of rainwater.The gas with smell overflows to pollute the air,and the putrid and fermented sundries are discharged into the water by the rainwater and pollutes the water body.The article introduces a method to improve the rainwater inlet.The structure of rainwater inlet is not changed and a device is only installed within the rainwater inlet,which can prevent the smell of rainwater inlet from overflowing and prevent the sundries from falling into.This method can be widely applied in the similar projects.
