Anti-blocking drainage pipeline for municipal bridge and working method of anti-blocking drainage pipeline

Abstract

The invention discloses an anti-blocking drainage pipeline for a municipal bridge and a working method of the anti-blocking drainage pipeline. The upper end and the lower end of a filter box communicate with a water inlet pipe and a water outlet pipe correspondingly, a filter plate is arranged in the filter box, and the two sides of the filter box are connected with collecting devices. The pipeline is simple in structure, accumulated water falling into a collecting box from the water inlet pipe can be filtered through the inverted-V-shaped filter plate, impurities in the accumulated water can be reduced, blockage of the bridge drainage pipe is reduced, the filtered impurities can enter the collecting box through the discharging opening and fall into the collecting box through gaps between the material guiding plates, the material guiding plates are connected with the inner wall of the collecting box through springs, reverse flowing of impurities is avoided, the backflow preventing effect is achieved, meanwhile, the material pushing device can press large impurities between the material guiding plates, blockage and impurity retention are avoided, the bridge drainage pipe can normally drain water, accumulated water on the surface of a bridge is reduced, and the labor intensity of workers is reduced.

Description

technical field [0001] The invention belongs to the field of sewage treatment, in particular to an anti-clogging drainage pipe used for municipal bridges and a working method thereof. Background technique [0002] With the continuous construction of urban modernization, there are more and more drainage pipes used in cities, and bridge drainage is also one of them. [0003] In order to avoid the water on the bridge, the drainage of the bridge deck is usually through the installation of drainage pipes, through which the accumulated water on the bridge deck is discharged into the urban sewage pipes to keep the bridge deck dry, but the accumulated water on the bridge deck is wrapped Sewage with impurities such as sediment and dead leaves is often prone to blockage of the drain pipe when it is discharged, resulting in poor drainage and serious water accumulation on the bridge. It is often necessary to manually clean the drain outlet, which increases the number of staff Labor int...

Problems solved by technology

The trash rack designed at the drain can isolate and block large-scale debris such as plastic bags and branches in the sewage, so as to ensure that the drainage pipe will not be blocked by these large-scale debris; the motor drives the stirring shaft to rotate, so that the stirring blades It can always stir the water body at the outlet, avoid the accumulation of sediment at the outlet, and prevent the blockage of the drainage pipe; the filter box can filter the sediment in the water, and the pyramid-shaped filter screen on the bottom plate can filter The silt that has passed through is discharged to both sides, so as not to block the nozzle of the second drainage pipe, so as to ensure smooth drainage. However, this patent simply isolates large-volume sundries such as plastic bags and branches, and cannot achieve effective drainage. Separation treatment, affecting the discharge of water flow when there is a lot of garbage accumulation
