A curbstone with drainage and sewage interception functions

Abstract

The invention relates to the technical field of urban road rainwater treatment, in particular to a kerb with the drainage function and the pollutant intercepting function in an urban road rainwater treatment system. The kerb comprises a water inlet, an overflow port, a drainage channel, an overflow channel and a rainwater grating. The rainwater grating is arranged at the water inlet, the included angles between grating bars of the rainwater grating and the inflow direction of the rainwater runoff ranges from 108 degrees t 135 degrees, and the drainage channel is arranged at the bottom of the overflow channel and communicated with a catch basin. The kerb has certain drainage capacity, can make excessive rainwater flow into the greenbelt so as to effectively delay occurrence of the peak value, and can effectively improve the overall drainage capacity of an urban road and reduce the occurrence frequency of urban inland inundation. The kerb further achieves hierarchical control over rainwater runoff pollutants, effectively improves the quality of discharged rainwater and reduces rainwater runoff pollution loads. The kerb can be produced through a modular unit and thus is convenient to construct, install, clean and maintain.

Description

technical field [0001] The invention relates to the technical field of urban road rainwater treatment, in particular to a curb in an urban road rainwater treatment system, in particular to a curb with drainage and sewage interception functions. Background technique [0002] my country is in a critical period of building a well-off society in an all-round way, with unprecedented speed and scale. Roads play a pivotal role in urban planning and construction. Under the background of rapid urbanization, the impermeable surface area of ​​roads continues to increase, and rainwater cannot infiltrate, resulting in increased surface rainwater runoff. At present, the proportion of my country's urban roads to construction land is generally 10-15%, and some foreign cities even exceed 30-40%. Therefore, in order to coordinate the contradiction between people and the environment in urban development, how to grasp the increasing relationship between roads and the urban environment, and pro...
