The utility model is characterized in that a water inlet, a well, a branch pipe, a drainage hole and a cover plate are characterized in that the top cover plate of the rainwater nozzle is a permeable concrete material, the upper part of the water flow can penetrate into the well through the permeable concrete, and the pipe is provided with a strip drainage hole on the branch pipe and the upper part of the upper part of the branch pipe is structured. The material is ordinary concrete and the lower part of the structure is made of water permeable concrete with equal strength. The shape of the branch pipe is straight wall arch and the inner tube wall is round. The water flowing into the pipe part can penetrate into the underground through the drainage hole and the permeable concrete. Compared with the conventional stone masonry and concrete material, it is simple in construction and short in construction period. It has the advantages of high carrying capacity and high utilization coefficient of channels, which can ensure that the soil particles can be prevented from entering the branch pipe while the rain is flowing into the soil, and the partial gully rain water nozzle has the ability to strengthen the water collecting capacity of the rain water outlet, increase the water content of the soil under the unpermeable ground in the city, slow down the ground settlement and prevent the rainstorm from flooding the pavement. And the effect of reducing the surface temperature of the ground.

偏沟式雨水口
本专利技术涉及不透水地面排水渗水系统,具体涉及偏沟式雨水口。
技术介绍
雨水口是雨水进入城市地下的入口,收集地面雨水的重要设施。道路、广场草地,甚至一些建筑的屋面雨水首先通过箅子汇入雨水口。作为城市排水管系汇集雨水径流的瓶颈,又是城市非点源污染物进入水环境的首要通道,它既为城市道路排涝,又为城市水体补水。在城市排水管网设计中,雨污排水管网是分离的,生活污水通过专用污水管道被送到污水处理厂,而雨水口则只负责雨水收集防洪防涝排放。随着中国工业化、城市化的不断发展,城市生活越来越方便,但随之而来的,不透水材料的铺设使用,使得城市土壤硬化严重。不透水地面的增加,使得暴雨来临时,路面雨水排解困难,单纯的不透水雨水口盖板和支管已经不能满足城市的排水量,给城市的交通造成了很大压力。本技术,正截面设置为直墙拱形,增加了水管承载能力,便于周边密实的铺设,利用了排水孔及透水混凝土的透水作用,极大的增加了雨水管的透水性能以及雨水口的集水能力,使得雨水口中流经支管的雨水渗入到不透水路面下的土壤中,旨在提高区域整体的蓄水量,并减轻降雨对城市防洪、防灾的压力,是一个值得推广的创 ...
