Through such a structure, road surface water accumulation can be reduced, rainwater can be drained and urban surface source pollution can be controlled. At the same time, the outer wall is made of concrete, which has the characteristics of high strength, anti-seepage and strong bearing capacity.
[0007] Preferably, a dirt interception basket is installed in the middle of the inner side of the outer wall. With such a structure, the problem of water accumulation caused by larger impurities clogging the PC pipe can be reduced. At the same time, it is only necessary to clean the dirt interception basket regularly during use.
[0008] Preferably, a filtering inner cylinder is provided at the bottom of the sewage interception basket. With such a structure, mud, sand and other debris can be easily cleaned, thereby fundamentally solving the problem of polluted water areas discharged from rainwater outlets and integrating into the landscape.

Through such a structure, the sediment in rainwater and road sewage can be filtered out, and the tiny bacteria carried in the rainwater and road sewage can be killed.
[0011] Preferably, the cover plate is smaller than the length of the outer wall and is used in conjunction with the outer wall, the sewage interception basket is above the filter inner cylinder, and the first through holes are symmetrically arranged. Through such a structure, it is easy to clean mud and sand, fundamentally solving the problem of rainwater outlets discharging polluted waters and integrating into the landscape.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0023] like Figures 1 to 5 As shown, a sponge city environmentally friendly overflow well described in an embodiment of the utility model includes an outer wall 1; a cover plate 12 is installed on the top of the outer wall 1, and a group of symmetrical first through holes 14 are opened on the side wall of the outer wall 1; a PC pipe 13 is fixedly connected to the middle of the first through hole 14. During operation, rainwater and road sewage will pass through the cover plate 12 into the interior of the outer wall 1. The material of the outer wall 1 is concrete. After a series of filtration, it will pass through the PC pipe 13 and flow into the municipal rainwater pipe. Through such a structure, road surface water can be reduced, rainwater can be discharged and urban surface source pollution can be controlled. At the same time, the outer wall 1 is made of concrete, which has the characteristics of high strength, anti-seepage and strong bearing capacity.
[0024] like Figure 3 As shown, a sewage interception basket 2 is installed in the middle of the inner side of the outer wall 1. When working, rainwater and road sewage will pass through the sewage interception basket 2, and relatively large impurity particles will be filtered by the sewage interception basket 2. Through such a structure, the problem of water accumulation caused by larger impurities clogging the PC pipe 13 can be reduced. At the same time, it only needs to clean the sewage interception basket 2 regularly during use.
[0025] like Figure 4 As shown, a filtering inner cylinder 3 is provided at the bottom of the sewage intercepting basket 2. When working, the initial rainwater enters the filtering inner cylinder 3 in sequence after passing through the sewage intercepting basket 2, is gradually purified, and is finally discharged into the municipal rainwater pipe. Through such a structure, mud and sand are easy to clean, which fundamentally solves the problem of rainwater outlets discharging polluted waters and integrates into the landscape.
[0026] like Figure 3 to Figure 4 As shown, a filter bag 4 is fixedly connected to the bottom of the filter inner cylinder 3. During operation, the later rainwater passes through the upper part of the middle filter material, overflows to the inner layer, and is directly discharged. The filter bag 4 has special filter material, which has the characteristics of filtering, deodorization, mosquito prevention, anti-clogging, anti-leakage, anti-backflow, and anti-overflow. Through such a structure, the water flow can be purified, and only the filter bag needs to be replaced regularly during use.
[0027] like Figure 4 As shown, a second through hole 41 is opened in the middle of the filter bag 4; the filter inner cylinder 3 extends to the interior of the filter bag 4 through the second through hole 41. When working, the refined sewage will flow through the filter inner cylinder 3 to the PC pipe 13, and finally discharged into the municipal rainwater pipe. The filter material has a biodegradable function and is easy to clean mud and sand. Through such a structure, the mud and sand in rainwater and road sewage can be filtered out, and the tiny bacteria carried in the rainwater and road sewage can be killed.
[0028] like Figures 1 to 5As shown, the cover plate 12 is smaller than the length of the outer wall 1 and is used in conjunction with the outer wall 1. The sewage intercepting basket 2 is above the filter inner cylinder 3. The first through holes 14 are symmetrically arranged. When working, the cover plate 12 can be pulled open. The sewage intercepting basket 2 and the filter inner cylinder 3 are both made of detachable and replaceable materials. When they are used for a long time or are blocked by some larger impurities, they can be opened and replaced in turn. Through such a structure, it is easy to clean up mud and sand, fundamentally solve the problem of rainwater outlets discharging polluted waters, and integrate into the landscape.
[0029] like Figure 1 As shown, a handle 5 is fixedly connected to the top of the cover plate 12; the handle 5 is symmetrically arranged. During operation, when it is necessary to replace or repair other objects inside the outer wall 1, the cover plate 12 needs to be pulled open. At this time, two handles 5 can be installed on the top of the outer wall 1. Through such a structure, the cover plate 12 can be pulled up more conveniently, saving the time of pulling up the cover plate 12, and achieving the purpose of replacing and repairing the objects inside the outer wall 1 more timely.
[0030] During operation, rainwater and road sewage will pass through the cover plate 12 and enter the interior of the outer wall 1. The material of the outer wall 1 is concrete. After a series of filtration, they will flow into the municipal rainwater pipe through the PC pipe 13. The rainwater and road sewage will pass through the sewage interception basket 2, and the relatively large impurity particles will be filtered by the sewage interception basket 2. The initial rainwater will enter the filter inner cylinder 3 in turn after passing through the sewage interception basket 2, and will be gradually purified and finally discharged into the municipal rainwater pipe. The later rainwater will pass through the upper part of the middle filter material, overflow to the inner layer, and be directly discharged. The filter material bag 4 has special filter material, which has the characteristics of filtering, deodorization, mosquito prevention, anti-blocking, anti-leakage, anti-backflow, and anti-overflow. The refined sewage will pass through the filter inner cylinder 3 to the PC pipe 13, and finally be discharged into the municipal rainwater pipe. The filter material has biodegradability and is easy to clean mud and sand. The cover plate 12 can be pulled open. The sewage interception basket 2 and the filter inner cylinder 3 are both detachable and replaceable. When they are used for a long time or are blocked by some larger impurities, they can be opened and replaced in turn.
