Rain sewage diversion reforming system for old residential area

Abstract

The invention relates to a rain sewage diversion reforming system for an old residential area. An original combined pipe of the old residential area is taken as a rain water pipe, and a sewage pipe is arranged in the original combined pipe to form a pipe-in-pipe structure; a booster pump is arranged additionally to form a low-pressure flow sewage conveying system; one end of the rain water pipe is communicated with a rain water regulating pond, and the other end of the rain water pipe is communicated with an urban rain water pipe network; one end of the sewage pipe is communicated with a septic tank, and the other end of the sewage pipe is communicated with the urban rain water pipe network. By adopting the rain sewage diversion reforming system, the defects such as excavation operation, influence on the normal life of the residential area, high cost, the need of a sufficient construction site and the need of knowing the pipeline distribution situation in the residential area caused by the implementation of rain sewage diversion construction through large-scale diversion system reconstruction and a non-excavation technology are overcome. Rain sewage diversion is realized by using low-pressure flow conveying and pipe-in-pipe technologies, and the rain sewage diversion reforming system has the advantages of avoidance of the occupation of roads in the residential area during construction and avoidance of the influence on the daily life of residents; sewage is conveyed by adopting low-pressure flow, so that the sewage flow speed is increased, sedimentation is reduced, the discharge capacity is increased by over 50-100 percent, and the problem of overflow of rain water in case of storm is solved.

Description

technical field [0001] The invention relates to a rain-sewage diversion system, in particular to a rain-sewage diversion transformation system for an old community. Background technique [0002] There are a large number of old communities with combined drainage systems built in the 1970s and 1980s in our country, and the combined rain and sewage systems of the old communities are far from meeting the requirements of modern environmental protection. According to the Guiding Opinions of the General Office of the State Council on Strengthening the Construction and Management of Urban Underground Pipelines - Guobanfa [2014] No. 27 requires speeding up the construction of rainwater and sewage diversion in old communities and improving the utilization rate of urban rainwater, the transformation trend of rainwater and sewage diversion in old communities It must be done. [0003] Before the present invention was made, the existing reconstruction of the old community was to rebuild ...

AI Technical Summary

Problems solved by technology

[0003] Before the present invention was made, the existing reconstruction of the old community was to rebuild the large-scale diversion system, which required a large number of excavation operations, which not only seriously affected the normal life of the residents of the community, but also cost very high; the use of trenchless technology To implement the rain and sewage diversion construction, it needs enough construction sites and detailed pipeline distribution in the community, and the cost is also very high, and these are difficult to realize during the renovation process, which seriously affects the rain and sewage diversion reconstruction project of the old community. This is the main obstacle for a large number of old communities that have not been renovated
