Problems solved by technology

[0007] In order to overcome the serious pollution of the combined overflow water in the above-mentioned intercepting combined drainage system and the great impact on the operation of the sewage plant, the high cost of the pipeline network of the separated drainage system, the large underground space occupation, the large impact on traffic during maintenance, and the prominent initial rainwater runoff pollution , and the problems of building overflow water storage tanks and initial rain runoff storage tanks are expensive and occupy valuable urban land. Based on the idea of ​​intercepting small flow initial ground runoff on the same line, the present invention proposes a double-layer rain-sewage composite drainage inspection Drainage systems for towns and communities based on wells or further combined with the same line split double-deck drainage pipes and canals

Embodiment 1

[0043] Example 1, see figure 1 , figure 2 as well as image 3 :

[0044] In the figure, this is a non-intercepted co-line split double-layer drainage system, which is mainly composed of upstream and downstream drainage pipes 12, 14 and rain and sewage composite double-layer drainage inspection well 13. The rain and sewage composite double-layer drainage inspection well is mainly composed of The well cover 1, the well body 2, the vent pipe 3, the well neck 4, the human ladder 5, the intermediate movable interlayer 6, the movable opening and closing cover plate 7 and so on. The well body 2 can be designed to be round or rectangular according to needs. The well body is provided with an openable and closable middle movable interlayer 6, which divides the inspection well into upper and lower layers. The lower layer is connected to the sewage pipe and the upper layer is connected to the rainwater pipe and is on the interlayer. A vent pipe 3 is provided to connect the upper and lower l...

Embodiment 2

[0047] Example 2, see Figure 4 , Figure 5 as well as Image 6 :

[0048] This is a cut-off and same-line split double-layer drainage system, which is mainly composed of upstream and downstream drainage pipes 12 and 14 and rain and sewage composite double-layer drainage inspection well 13. The rain and sewage composite double-layer drainage inspection well is mainly composed of manhole cover 1, well The body 2, the vent pipe 3, the well neck 4, the man ladder 5, the middle movable interlayer 6, the movable part of the middle movable interlayer 7, the intercepting hole (slit) 8 and so on. The difference from the structure of Example 1 is that there are cut-off holes / slits 8 in the middle movable interlayer 6, which are round or strip-shaped holes / slits with a fixed opening size, allowing small flow of rainfall runoff or road sprinkling runoff By intercepting to the lower layer and connecting to the sewage pipe, an intercepting double-layer rain and sewage composite drainage inspe...

Embodiment 3

[0049] Example 3, see Figure 7 , Figure 8 as well as Picture 9 :

[0050] This is a cut-off and same-line split double-layer drainage system, which is mainly composed of upstream and downstream drainage pipes 12 and 14 and rain and sewage composite double-layer drainage inspection well 13. The rain and sewage composite double-layer drainage inspection well is mainly composed of manhole cover 1, Well body 2, vent pipe 3, well neck 4, human ladder 5, middle movable interlayer 6, movable opening and closing cover 7, interception hole / slit 8, interception hole cover 9, spring 10, and loose leaf 11. The difference from the structure of Example 1 is that the intercepting structure provided on the intermediate movable interlayer 6 is adjustable. The intercepting structure is specifically composed of intercepting holes / slits 8, intercepting hole cover plates 9, springs 10, and loose leaves 11. The interceptor cover 9 is installed on the interceptor / slot 8 through the loose leaf 11 and...

Abstract

The invention requests to protect a drainage system used in cities, towns and communities, which is formed by connecting at least a co-line divided-flow dual-layer drainage pipe and channel or a common drainage pipe and channel with a rainwater-sewage compound dual-layer manhole. An intercepting rainwater-sewage compound dual-layer drainage manhole can be arranged on the drainage system accordingto the requirement so as to realize that the initial surface runoff is intercepted into a sewage pipe and channel and is delivered to a sewage treatment plant to be treated, and a non-intercepting rainwater-sewage compound dual-layer drainage manhole can be arranged according to the requirements of direction change, gradient change, connector change, pipe and channel intersection, examination andrepair of linear pipes and channels every certain distance and other special purposes. The drainage system can realize individual delivery and drainage of the rainwater and sewage by layers on the same pipeline and has the characteristics of simple pipelines, few manholes, low investment, operation and maintenance cost, capability of reducing the pollution effects of first rain runoff in an economic and effective manner, and no rainwater-sewage interflow and overflow water pollution, etc.

Description

Technical field [0001] The invention belongs to the technical field of urban drainage systems and environmental protection, and specifically relates to a drainage system. Background technique [0002] At present, there are mainly two systems in the field of urban drainage: combined system and split system. The former transports and discharges rainwater and urban sewage in the same pipe and canal, and the latter transports rainwater and urban sewage in two pipe canal systems separately. And emissions. At present, they all have certain defects and shortcomings respectively. [0003] For the intercepted combined drainage system, the main problems are: (1) There is rain and sewage combined overflow water in the rainy season, which contains a large amount of organic matter, suspended matter (SS) and pathogenic microorganisms, and it is directly discharged into the water body without treatment. The pollution effect is great; (2) When the drainage pipeline is far away from the receiving...
