Background
Organized drainage refers to a drainage mode in which rainwater is guided to the ground or underground pipe ditches through drainage devices such as gutter channels and rainwater pipes, and is a related technology for treating waterlogging with the shortest treatment period. At present, most of urban rainwater drainage systems are incomplete organized drainage systems, and only the drainage paths are organized, namely the urban rainwater drainage systems are drained into river channels through pipelines. Fully organized drainage is not only organized in the drainage path, but also organized in time and space.
Most cities in China have the problem of road water accumulation with different degrees caused by rainfall. According to the concept of an incomplete drainage system, most of the existing schemes for treating road accumulated water are to replace a drain pipe with a larger diameter, enlarge the drainage section of a ditch, increase the drainage capacity of a drainage pump and the like. Wherein, the replacement of the drain pipe needs to dig the road, which affects the traffic and has large investment.
At present, when heavy rainfall appears in the city, there is a large amount of water pumps to drain at the ponding point of difference, because rainfall often is greater than the design standard of rainwater pipeline, the displacement in the pipeline has been saturated, the water of water pump suction drain pipe can not be discharged smoothly, often form the circulating water, though a large amount of water pumps are in the operation like this, but do not really play the drainage effect, this will cost a large amount of manpowers, material resources and electric power etc. only treat that rainfall is little, drainage pipeline's drainage pressure has alleviateed, water pump suction ponding just really has the effect, ponding just can be discharged.
