Embodiment Construction
[0024] The present invention will be further described below with reference to the accompanying drawings.
[0025] The construction method for the diversion of rainwater and sewage at the source of the built-up area of the present invention includes the construction of a community with a rainwater and sewage system, the construction of a community with only a combined pipeline system, the construction of a community with only a combined pipeline system and no new rainwater riser can be established, and For the construction of rainwater pipeline districts that only have a combined pipeline system and cannot build new districts.
[0026] The community with rainwater and sewage system includes the municipal rainwater pipe network 5, the municipal sewage pipe network 9, the confluence riser 7 set up on the outer wall of the building, the district confluence pipeline 8 set up underground, and the district set underground and connected to the municipal rainwater pipe network Rainw...

The invention discloses a construction method for rainwater and sewage diversion of a built-up area source. Comprising the steps of construction of a community with a rainwater and sewage system, construction of a community only with a confluence pipeline system, construction of a community only with a confluence pipeline system and incapable of building a new rainwater vertical pipe, and construction of a community only with a confluence pipeline system and incapable of building a new community rainwater pipeline. The construction method for the community with the rainwater and sewage system comprises the steps that a new rainwater vertical pipe is arranged on an outer wall of a building, the top of the new rainwater vertical pipe is connected with a rainwater hopper at the top of the building, the lower end of the new rainwater vertical pipe is connected into a community rainwater pipeline, then the top of a converging vertical pipe is blocked, and then the community converging pipeline is regarded as a community sewage pipeline. According to the construction method for rainwater and sewage diversion of the built-up area source, rainwater and sewage diversion is achieved from the source, rainwater and sewage mixed flow can be effectively prevented, river pollution and overload of a sewage treatment plant can be prevented, and waste of corresponding construction resources can be avoided.
Description
technical field [0001] The invention relates to an urban drainage system, in particular to a construction method for diverting rain and sewage at the source of a built-up area. Background technique [0002] In the past, due to the lack of segregation of drainage pipes according to the source of water in urban infrastructure construction, especially in highly built-up areas, rainwater and sewage are combined into a combined riser, that is, a combined rainwater and sewage drainage system. As a result, part of the source sewage flows into the river channel through the confluence riser through the rainwater pipeline, causing black and odor pollution, and part of the rainwater enters the sewage pipeline through the confluence riser, which greatly affects the treatment efficiency of the sewage treatment plant. [0003] With the development of the economy and the enhancement of environmental awareness, coupled with the increasingly precious water resources, in order to make better ...
