Sewer filter

Abstract

The invention belongs to the technical field of road facilities and particularly relates to a sewer filter. The sewer filter is characterized by comprising a well cover, an upper box and a lower box, a plurality of through holes 3-5 cm are uniformly formed in the wall of each of the boxes, the well cover is arranged at the upper end of the upper box embedded in the lower box, a pressure sensor is arranged on one side of the lower end of the upper box, and warning lights are arranged on street lamps near the well cover. The sewer filter is simple in structure and convenient to use; by the secondary filter method integrating the upper box and the lower box, the sewers are prevented from blocking, in this way, even in rainy days, water on the road of the urban flows smoothly; production cost is lowered so as to facilitate promotion and application.

Description

(1) Technical field [0001] The invention relates to a sewer filter, which belongs to the technical field of road facilities. (2) Background technology [0002] The urban road rainwater drainage system is a complete set of engineering facilities composed of sewer outlets, rainwater pipes, inspection wells, water outlets and other structures. Its function is to quickly remove the rain and snow on the ground to ensure the normal traffic of vehicles and pedestrians. , improve the sanitary conditions of the city, and avoid damage to the pavement structure due to water immersion. The sewer outlets in the urban road rainwater drainage system are usually located at intersections, the lowest point of the road surface and at certain distances from the curb edge of the road. [0003] At present, the sewer wellheads of urban road rainwater drainage systems in China are not equipped with filtration systems. When the rainy season comes, soil, sand, stones, leaves, garbage, etc. on th...

AI Technical Summary

Problems solved by technology

[0003] At present, the sewer wellheads of urban road rainwater drainage systems in China are not equipped with filtration systems. When the rainy season comes, soil, sand, stones, leaves, garbage, etc. on the ground may enter the sewer along with the rainwater, which will cause sewer blockage in the long run and reduce The drainage capacity of the sewer is affected, which affects the normal operation of the urban drainage system, causing urban waterlogging and environmental pollution. Even when the rainstorm comes, the blocked sewer is easy to lift the manhole cover, which poses a great threat to the safety of pedestrians.
