However, most cities are clear in four seasons, the rainfall difference of each season is large, a large amount of rainfall occurs in a short time in summer and autumn, and the rainfall is little in spring and winter. This leads to the problem that rainfall cannot be discharged smoothly in summer and autumn if the size of the urban drainage pipe is insufficient, which causes urban waterlogging. If the size of the drain pipe is enough, in spring and winter, the water collecting tank on the ground and the underground pipeline form a passage because the rainfall is less, and the drain pipe in most cities has the function of pollution discharge, so that a large amount of peculiar smell is diffused through the water collecting tank and becomes a place for breeding bacteria and mosquitoes and flies.
At present, some urban water pipe systems exist, independent collection and treatment of urban rainwater can be achieved, and the urban rainwater can be reused or the existing problems of the existing urban water pipe systems can be solved by arranging the baffle plates at the sewage discharge pipe openings. However, the inventor finds that the collected rainwater can carry a large amount of pollutants such as heavy metals or organic pollutants after passing through the ground of the city, and the direct recycling obviously does not meet the requirements of sanitary cities, green cities or healthy cities, but obviously does not bring disadvantages such as increasingly serious shortage of fresh water resources if the rainwater is not recycled. Furthermore, the cost of recycling rainfall in all the existing urban water pipe systems for sponge cities is high.

The first embodiment is as follows:
the present invention is described in detail below with reference to fig. 1 to 4, and specifically, the structure is as follows:
the embodiment provides a water pipe system of a sponge city, as shown in fig. 1, which comprises a pipe well 2, a rainwater recovery tank 5, a drainage pipe ditch 1 and a plurality of water storage tanks, wherein the rainwater recovery tank 5 is connected with the pipe well 2 through a rainwater pipe 6; and a barrier is arranged on the rainwater recovery tank 5. The plurality of water storage pools are respectively connected to different height positions of the pipe shaft 2 through pipelines, and the water storage pools are arranged at intervals on the same side of the pipe shaft 2 and are sequentially connected; wherein, the water storage tank closest to the pipe shaft is connected with the drainage pipe ditch 1 through a pipeline.
In this embodiment, two water storage tanks, namely a first water storage tank 3 and a second water storage tank 4 are provided, the first water storage tank 3 and the second water storage tank 4 are connected to different height positions of the pipe shaft 2, and the first water storage tank 3 is connected with the second water storage tank 4 through a pipeline. The first water storage tank 3 is connected with the drain pipe ditch 1, and a control valve is arranged on a pipeline between the first water storage tank and the drain pipe ditch 1. It will be appreciated that in other embodiments, three or more than three reservoirs may be provided, selected in particular according to the actual rainwater treatment requirements.
The drain 1 mainly refers to a sewer piping system of a city, and in a conventional city, the drain 1 is used for both sewage discharge and rainwater drainage. Since the drain pipe 1 is responsible for rainwater drainage, since rainwater is mixed with sewage, it is necessary to perform drainage or recycling after sewage treatment for environmental protection, and the cost of sewage treatment is high. In this embodiment, the rainwater collection tank 5 is not communicated with the drain pipe 1, and therefore, there is no problem that the drain pipe 1 returns the smell through the rainwater collection tank 2.
When in use, the drainage pipe ditch 1 is arranged below the rammed earth layer 71 of the permeable pavement by taking the road as a reference, and the upstream of the drainage pipe ditch 1 is used for receiving and draining water. The upper layer of the rammed vegetarian soil layer 71 is a waterproof isolation layer 72, a drainage ditch 73 is formed on the waterproof isolation layer 72, and the drainage ditch 73 is connected with the pipe well 2. The drainage ditch 73 is a drainage pipe made of a material having water seepage capability.
As shown in fig. 2, a rainwater receiving opening 23 and a plurality of water discharge openings are formed in the side wall of the piping shaft 2, and the rainwater receiving opening 23 is communicated with the rainwater piping 6. In this embodiment, two drainage openings are provided on the side wall of the pipe shaft 2, a first drainage opening 25 is provided near the bottom of the pipe shaft 2, and a second drainage opening 24 is provided at a set height of the first drainage opening 25. The first water outlet 25 is connected with the first water storage tank 3 through a pipeline, and the second water outlet 24 is connected with the second water storage tank 4 through a pipeline.
In the present embodiment, the pipe shaft 2 has a cylindrical structure. The wellhead below of piping shaft 2 sets up filter frame 26, and filter frame 26 is located rainwater receiving port 23 below for filter the water that comes of rainwater pipeline 6. An outer sleeve 21 is fixed on the outer side of the pipe well 2; the outer sleeve 21 corresponds to the outside of the second drain opening 24. The outer sleeve 21 is integrally cylindrical, a cavity is formed in the outer sleeve, and the cavity and the outer wall of the pipe well 2 form a water receiving groove 22. The water receiving tank 22 is communicated with the drainage ditch 73, and the rainwater pipeline 6 is not communicated with the water receiving tank 22.
Further, outer tube 21 and tube well 2 integrated into one piece, outer tube 21 can adopt the material that has the permeability, and the rainwater of infiltration layer infiltration can infiltrate in receiving groove 22, gets into second tank 4 through the pipeline, improves retrieval and utilization efficiency.
When in use, the pipe shaft 2 is arranged underground, and the top of the pipe shaft is flush with the road surface. And a well cover or a steel barrier is arranged at the well mouth of the pipe well 2 and used for protecting. The recovered rainfall firstly enters the first water storage tank 3 through the first water outlet 25, and when the rainfall is large, after a large amount of water is stored in the pipe shaft 2, the liquid level in the pipe shaft 2 rises; when reaching the second water outlet 24, the water is discharged into the second water storage tank 4 through a pipeline. At this time, the water in the pipe shaft 2 at the second water discharge port 24 is simply relatively static, so that partial precipitation is performed, and particularly, after the initial stage of rainfall, the pollutants on the ground are taken away by the initial rainwater, and the quality of the rainwater at this time is better than that of the rainwater entering the first water storage tank 3.
As shown in fig. 3, a top cover is installed on the top of the first water storage tank 3, a first partition plate 32 is installed in the first water storage tank 3 along the vertical direction, and the first water storage tank 3 is divided into two spaces with different sizes by the first partition plate 32, wherein the larger space is the first sedimentation tank 31, and the smaller space is the first water storage tank 33. The height of the first partition 32 is less than the height of the side wall of the first storage tank 3. The first water discharge port 25 of the piping shaft 2 is connected to the first sedimentation tank 31, and the first water storage tank 33 is connected to the lift pump through a pipeline.
All the incoming water enters the first sedimentation tank 31 of the first water storage tank 3 through a pipeline for sedimentation, and then enters the first water storage tank 33 close to the upper part through the liquid level difference. The water in the first water storage tank 33 can be recycled by a lift pump, or can enter the second water storage tank 4 for retreatment by self-pressure through a pipeline for utilization.
When the water quality does not meet the requirement, the water is pressed into the drainage pipe ditch 1 by self pressure after the control valve is opened through a pipeline between the water and the drainage pipe ditch 1, and then the water enters the sewage treatment device for treatment. When the rainfall is large or the liquid level in the drain 1 is high, the water in the first reservoir 3 may be pumped into the second reservoir 4 by a lift pump connected to the first reservoir 33. Sludge and the like at the bottom of the first sedimentation tank 31 can be treated by a sludge scraper or the like and then pumped out for treatment in a municipal sludge treatment manner.
As shown in fig. 4, a top cover is installed on the top of the second water storage tank 4, a second partition plate 41 is installed in the second water storage tank 4 along the vertical direction, and the second water storage tank 4 is divided into two spaces with different sizes by the second partition plate 41, wherein the larger space is a second sedimentation tank 42, and the smaller space is a second water storage tank 43. The height of the second partition plate 41 is less than the height of the side wall of the second storage tank 4. The second water discharge 24 of the pipe shaft 2 is connected to the second sedimentation tank 42. The second reservoir 43 is connected to a lift pump via a line for extracting water from the second reservoir 4.
The quality of water of storing in the second tank 4 is high for the quality of water in the first tank 3, because carry out the rainwater in the second tank 4 and carry out preliminary treatment through first tank 3, perhaps through the rainwater that the infiltration got into, consequently, can directly utilize.
The working principle of the embodiment is as follows:
the water pipe system of the present embodiment is generally applied to a road and sidewalks on both sides, and since the outer layer of the road is conventionally paved with asphalt, the asphalt pavement is characterized by water impermeability, and thus, if a certain amount of rainfall is present, the rainwater is collected into the rainwater recovery tank 5. However, when the rainfall is small or in the early stage of rainfall, the rainwater washes the road surface, and pollutants enter the rainwater recovery tank 5 along with the rainwater and enter the first water storage tank 3 through the first water discharge port 25 below the pipe shaft 2. Through detecting the back, if pollutant concentration is too high, can enter into the drain pipe ditch 1 through the autogenous pressure through the elevator pump or open and the drain pipe ditch 1 between the control valve on the pipeline, join with sewage and enter into sewage treatment plant after and handle, but this moment, the total amount of rainwater is less, and it is limited to increase the treatment cost. When rainfall is frequent, even if the rainfall is small, the pollutant concentration in the rainwater is low, and the rainwater can be recycled by pumping water through the lifting pump according with direct recycling.
On the sidewalk, in order to prevent skidding or the like, a technology of laying antiskid bricks is generally adopted, and the antiskid bricks can penetrate into a water seepage layer downwards when the rainfall is small. And then collected in the water receiving tank 22 of the pipe well 2 through the drainage ditch 73 after the waterproof isolation layers 72 are collected. Because the rainwater at this moment has passed through two or more layers of filtration, the quality of the rainwater that permeates into escape canal 73 is higher than the rainwater quality of retrieving through rainwater accumulator 5 relatively, consequently, this partial rainwater is direct to be linked together with second tank 4, directly enters into in the second tank 4 and carries out recycle.
The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
