Description

A kind of urban road drainage system and method

technical field

The invention relates to the technical field of urban road drainage, in particular to an urban road drainage system and method.

Background technique

Due to the rapid development of urban expansion and urbanization, there are certain defects in the drainage system of large and medium-sized cities in my country. Existing road drainage system is provided with sewer cover or drainage rain grate usually on drainage well. The manhole cover and the drainage rain grate are provided with drainage holes, although the drainage holes have a certain filtering effect on large-volume sundries such as leaves, their main function is still drainage, rather than filtering sundries. In addition, it is not advisable to set too many drainage holes, otherwise it will affect the bearing capacity of the manhole cover or the drainage grate, and there is a safety factor.

Based on the above reasons, the existing road drainage system usually sets a filter screen or a filter basket in the drainage well to filter large-volume sundries such as fallen leaves. The inventor believes that: the filter screen or the filter basket is installed in the drainage well, and long-term filtration will lead to the accumulation of too much sundries, which will affect the drainage performance. Therefore, sanitation personnel need to clean it regularly, and each time cleaning needs to open the well cover or drain the rainwater. The grate is very inconvenient.

Therefore, the inventor has proposed a kind of urban road drainage system.

After the drainage is completed, the block blocks the drain again and stores a certain amount of accumulated water in the drainage well;

Step 2: Open the shut-off valve and control the direction of the accumulated water flow through the reversing valve, so as to control one of the two nozzles to start spraying water. The water pressure acts on the water wheel to drive the water wheel to rotate clockwise; the water wheel drives the coaxial The belt pulley rotates, and then drives the belt to rotate, and the belt rotates to drive the drive horizontal bar and the drive vertical bar to move horizontally, and then pull the filter screen plate from the drainage well to the impurity removal well. The guide column on the top enters the linear buffer track of the reversing sleeve; continues to move horizontally, the guide column enters the helical reversing track to realize rotation, and then drives the filter screen plate to turn over, and pours the debris filtered on the filter screen plate into the miscellaneous removal well;

Step 3: Use the reversing valve to change the direction of the accumulated water, and control the other nozzle to spray water to drive the water wheel to rotate counterclockwise and drive the filter screen to reset.

When the urban road drainage system of the present invention is actually used, the drainage well is arranged on the side of the motorway, the miscellaneous well is arranged on the side of the green belt or the drainage well is arranged on the non-motor vehicle side, and the miscellaneous well is arranged on the sidewalk side. The process is relatively safe and will not hinder traffic.

3. Beneficial effects:

(1) The urban road drainage system of the present invention is equipped with a filter screen to filter large-volume sundries such as fallen leaves, which can prevent sundries from entering the drainage main pipe with accumulated water.
