a sewer interception

Abstract

The invention discloses a pollutant-intercepting gutter inlet which comprises a gutter inlet (5) and a rainwater strainer (2) mounted on the gutter inlet (5), and is characterized in that an intercepting weir (3) is arranged on a slope section at the periphery of the gutter inlet (5); and the intercepting weir (3) winds around the periphery of the gutter inlet (5). The pollutant-intercepting gutter inlet has the advantages that the bias of a pollutant-intercepting technology in the gutter inlet is overcome, small particle solid pollutants and large pollutants are intercepted outside the gutter inlet, the quantity of pollutants entering the gutter inlet is reduced, the blockage of an urban rainwater pipe network system is reduced, the pipeline dredge frequency is reduced, and the gutter inlet is conveniently maintained and managed.

Description

technical field [0001] The invention belongs to urban drainage systems, and in particular relates to a sewage intercepting rainwater outlet. Background technique [0002] The rainwater outlet, also known as the rainwater collection well, discharges rainwater into the main pipe through the water collection branch pipe. It is an auxiliary structure of the urban drainage system and an important part of urban road drainage. The rainwater outlet is composed of water inlet grate, well body and branch pipes. According to its form, it is divided into flat grate type, vertical grate type, partial groove type and combined type. Rainwater outlets are usually set at a certain distance in blocks, squares, street intersections and street gutters to collect rainwater on the ground and on the street surface, so as to prevent rainwater from flooding the road and causing water accumulation in the road or low-lying areas to hinder traffic or damage the road. The rainwater outlets can be div...

AI Technical Summary

Problems solved by technology

[0004] 1. The accumulated water will form splashes under the action of driving, which will affect the sight of subsequent vehicles;

[0005] 2. When the water accumulates to a certain thickness, it will form "water floating" when driving, causing the wheels to slip;

[0006] 3. Long-term immersion in water of asphalt mixture is easy to form peeling off, reducing the strength of road surface;

[0007] 4. Severe road accumulation of water washes side ditches and road surfaces, reduces the efficiency of municipal roads, and even destroys bridges and road surfaces, blocking normal traffic

Its disadvantage is that a large amount of pollutants in the rainwater enter the sewage intercepting hanging basket with the rainwater, and when the pollutants in the sewage intercepting hanging basket accumulate too much, the pollutants in the rainwater cannot be effectively removed

[0010] The above patented technologies belong to the sewage interception in the rainwater outlet. The sewage interception device installed at the lower part of the rainwater grate needs to be cleaned after the rain. It is troublesome to disassemble and install, and the maintenance management remains unchanged.
