Improved city drainage system

Abstract

The invention relates to the technical field of city drainage, in particular to an improved city drainage system. An original drainage system comprises a water inlet, a rainwater strainer A, a drainage pipe and a sewage branch pipe, and a connecting opening, a regulating device, a water storage opening, a water storage pond, a pond base, a water outlet pipe and an outdoor water pump are added by the improved city drainage system. The connecting opening is formed in the bent portion of the drainage pipe and the water inlet, the regulating device is placed in the water inlet, a rubber cover plate is limited in a cover plate groove, the cover plate groove is connected with the water storage pond water inlet, and the water outlet pipe is arranged at the bottom of the water storage pond. The original city drainage system is improved, the original drainage pipe is made full use of, an old pipe does not need to be detached, the road damage range is small, and the improved city drainage systemhas the huge advantage of saving the cost; when the rainfall amount is too large, a water storage function is opened by the water storage pond, the flood drainage capability of an underground pipe isimproved, water resources in the water storage pond can be used as firefighting water or greening water through the outdoor water pump, and the utilization rate of the water resources is increased.

Description

technical field [0001] The invention relates to the technical field of urban drainage, in particular to an improved urban drainage system. Background technique [0002] The drainage system is an important infrastructure of a modern city. In the construction of municipal construction and environmental treatment projects, the drainage system often occupies a large proportion of investment. In recent years, under the influence of global climate change, extreme weather such as heavy rain has had a huge impact on social management, urban operation and the production and life of the people. In order to protect the lives and property of the people, how to transform the urban drainage system to improve the ability to prevent waterlogging , become a technical problem to be solved. [0003] The drainage system in the prior art generally includes a plurality of interconnected drainage pipes buried in the ground, and a gully connected with the drainage pipes for receiving rainwater.

AI Technical Summary

Problems solved by technology

There are at least many technical defects in this solution in the prior art. It is necessary to remove a large area of ​​road surface to dig out the original drainage pipe, which has a great impact on the road surface, long construction period and high cost. After the original drainage pipe is dug out , basically can only be scrapped, and the new drainage pipes also need to spend a higher cost, which further leads to a high cost of renovation
