Description
Technical Field
[0001] This utility model relates to the field of overflow wells, specifically to a sunken green space overflow well structure. Background Technology
[0002] With the intensification of global climate change, urban flooding and water shortages are becoming increasingly severe. Sponge city construction, as an effective way to alleviate urban water ecological dilemmas, has become an important direction for sustainable urban development worldwide. Sunken green spaces, with their advantages of low construction and maintenance costs and wide applicability, are widely used in urban buildings, residential areas, roads, green spaces, and plazas. Through rainwater infiltration and purification, they not only effectively replenish groundwater but also reduce peak rainfall flow and control runoff pollution, playing a crucial role in improving urban resilience and ecological environment quality.
[0003] Overflow wells, as core facilities for efficient rainwater transport and drainage in sunken green spaces, currently generally adopt a surface-mounted storage well design. During rainfall, this structure collects surface runoff and directs rainwater into the soil or distant drainage systems via infiltration or pipelines. However, in extreme weather events such as heavy or continuous rainfall, the drainage capacity of existing overflow well structures is severely insufficient. Due to limitations in parameters such as the diameter of the transmission channel and the drainage slope, they cannot quickly divert large amounts of rainwater, causing rainwater to accumulate rapidly and overflow. This not only weakens the rainwater storage and purification functions of sunken green spaces but may also cause waterlogging in surrounding areas, exacerbating the risk of urban flooding, while increasing the operational pressure on downstream drainage systems, resulting in water waste and increased ecological governance costs. Therefore, there is an urgent need for technological innovation in existing overflow well structures to meet the practical needs of efficient drainage and ecological governance in sponge cities. Summary of the Invention
[0004] To address the problems of existing technologies, this utility model provides a sunken green space overflow well structure.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A sunken green space overflow well structure includes an overflow well body, and a flow guiding component is provided on the outside of the overflow well body. The flow guiding component includes thirty-six flow guiding pipes fixedly connected to the outside of the overflow well body. The thirty-six flow guiding pipes are divided into four groups, and the four groups of flow guiding pipes are set at different heights. The inside of the flow guiding pipes is connected to the inside of the overflow well body. Radial holes are opened on the outside of the flow guiding pipes, and the flow guiding pipes are arranged radially.
[0007] The above technical solution involves installing a guide pipe on the outside of the overflow well, allowing water to flow into the soil along the pipe. The radial holes inside the guide pipe continuously disperse the water flow into the surrounding soil, thus diverting the water flow to different locations and reducing the rate of soil saturation increase. This allows the soil to absorb more water, increasing the amount of water discharged and reducing the likelihood of the overflow well overflowing. Consequently, the overflow well can function for a longer period.
[0008] The overflow well body is equipped with a sinking component, which includes a flow channel opened inside the overflow well body. A baffle plate is fixedly connected inside the overflow well body, and the height of the baffle plate is half the height of the flow channel.
[0009] The above technical solution allows water to be discharged into the soil at the bottom of the overflow well via the downflow channel, while the baffle plate can block the soil at the bottom of the overflow well, reducing the possibility of soil entering the overflow well.
[0010] The top of the overflow well is provided with a first filter assembly, which includes a barrier cover slidably connected to the inside of the overflow well, and the barrier cover has a water inlet groove inside.
[0011] The above technical solution allows water to enter the overflow well by opening a water inlet channel inside the barrier cover, while stones and branches that come with the water flow are blocked.
[0012] The overflow well body is provided with a second filter assembly, which includes a filter cylinder that is slidably connected to the inside of the overflow well body, and the filter cylinder has filter holes inside.
[0013] Through the above technical solution, water can flow into the overflow well through the filter holes opened inside the filter cylinder, while small impurities such as leaves that come with the water flow will be blocked.
[0014] The overflow well body is equipped with a stabilizing component, which includes a limiting block fixedly connected to the inside of the overflow well body. The height of the limiting block is higher than the height of the guide pipe.
[0015] The above technical solution allows the position of the filter cylinder to be restricted by the limiting block. By placing the limiting block above the guide pipe, a large space is provided below, allowing water to flow smoothly into the overflow well body, and the limiting block will not obstruct the transmission of water flow through the guide pipe.
[0016] A support assembly is provided on the outside of the barrier cover. The support assembly includes a fastening ring fixedly connected to the outside of the barrier cover. The bottom of the fastening ring abuts against the top of the filter cylinder, and the outside of the fastening ring is slidably connected to the inside of the overflow well body.
[0017] The above technical solution uses fastening rings to reinforce the barrier cover, thereby ensuring its service life.
[0018] The barrier cover is configured as two layers. The first layer of the barrier cover is smaller than the second layer of the barrier cover. The first layer of the barrier cover is slidably connected to the inside of the overflow well body. The bottom of the second layer of the barrier cover abuts against the top of the overflow well body. The outer side of the first layer of the barrier cover is fixedly connected to the inside of the fastening ring.
[0019] The above technical solution involves setting the barrier cover in two layers. This allows the first layer of barrier cover to enter the overflow well body, enabling the water flow to enter the overflow well body completely. The second layer of barrier cover can also restrict the position of the barrier cover.
[0020] The radial holes are positioned downwards, and the end of the guide pipe furthest from the overflow well body is angled slightly downwards.
[0021] By setting the radial holes downwards, the soil above cannot enter the diversion pipe, thus ensuring the smooth use of the diversion pipe. Furthermore, the downward-facing end of the diversion pipe can increase the speed of water flow, thereby increasing the speed at which the water is absorbed by the soil.
[0022] Compared with the prior art, the beneficial effects of the utility model are: by setting a guide pipe on the outside of the overflow well, water can flow into the soil through the guide pipe, and the radial holes opened inside the guide pipe can continuously disperse the water flow into the surrounding soil, so that the water is discharged at different locations, thereby reducing the rate of increase in soil saturation, allowing the soil to absorb more water, thereby increasing the amount of water discharged, thus reducing the overflow well from overflowing, and thus ensuring that the overflow well can function for a longer period of time;
[0023] Furthermore, by setting the radial holes downwards, the soil above cannot enter the diversion pipe, thus ensuring the smooth use of the diversion pipe. The downward-facing end of the diversion pipe can increase the speed of water flow, thereby increasing the speed at which water is absorbed by the soil. Attached Figure Description

[0032] The present invention will be further described in detail below through embodiments. The embodiments are only used to illustrate the present invention and do not limit the scope of the present invention.
[0033] A sunken green space overflow well structure includes an overflow well body 1. A flow guiding component is provided on the outside of the overflow well body 1. The flow guiding component includes thirty-six flow guiding pipes 2 fixedly connected to the outside of the overflow well body 1. The thirty-six flow guiding pipes 2 are divided into four groups. The four groups of flow guiding pipes 2 are set at different heights. The inside of the flow guiding pipes 2 is connected to the inside of the overflow well body 1. Radial holes 3 are opened on the outside of the flow guiding pipes 2. The flow guiding pipes 2 are arranged radially.
[0034] By installing a guide pipe 2 on the outside of the overflow well body 1, water can flow into the soil through the guide pipe 2. The radial holes 3 inside the guide pipe 2 can continuously disperse the water flow into the surrounding soil, thereby changing the location of water discharge and reducing the rate of increase in soil saturation. This allows the soil to absorb more water, increasing the amount of water discharged and reducing the possibility of overflowing the overflow well body 1. This ensures that the overflow well body 1 can function for a longer period of time.
[0035] The overflow well body 1 is equipped with a sinking component, which includes a downflow channel 4 opened inside the overflow well body 1. A baffle plate 5 is fixedly connected inside the overflow well body 1, and the height of the baffle plate 5 is half the height of the downflow channel 4.
[0036] The water can be discharged into the soil at the bottom of the overflow well body 1 through the downflow channel 4, while the baffle plate 5 can block the soil at the bottom of the overflow well body 1, reducing the possibility of soil entering the overflow well body 1.
[0037] The overflow well body 1 is provided with a first filter assembly at the top. The first filter assembly includes a barrier cover 6 that is slidably connected to the inside of the overflow well body 1. A water inlet groove 7 is provided inside the barrier cover 6.
[0038] By opening a water inlet trough 7 inside the barrier cover 6, water can enter the overflow well body 1, while stones and branches flowing with the water will be blocked.
[0039] The overflow well body 1 is equipped with a second filter assembly, which includes a filter cylinder 9 that is slidably connected to the inside of the overflow well body 1, and the filter cylinder 9 has filter holes 10 inside.
[0040] Water can flow into the overflow well body 1 through the filter holes 10 inside the filter cylinder 9, while small impurities such as leaves that come with the water flow will be blocked.
[0041] The overflow well body 1 is equipped with a stabilizing component, which includes a limiting block 11 fixedly connected to the inside of the overflow well body 1. The limiting block 11 protrudes from the inner wall of the overflow well body 1, and the height of the limiting block 11 is higher than the height of the guide pipe 2.
[0042] The position of the filter cylinder 9 can be restricted by the limiting block 11. The bottom of the filter cylinder 9 contacts the top of the limiting block 11, and a gap is formed between the outer periphery of the filter cylinder 9 and the inner wall of the overflow well body 1. The limiting block 11 is set above the guide pipe 2, so that there is a large space below, allowing water to flow smoothly into the overflow well body 1, and the limiting block 11 will not block the transmission of water flow by the guide pipe 2.
[0043] The barrier cover 6 is provided with a support component on its outer side. The support component includes a fastening ring 8 fixedly connected to the outer side of the barrier cover 6. The bottom of the fastening ring 8 abuts against the top of the filter cylinder 9, and the outer side of the fastening ring 8 is slidably connected to the inside of the overflow well body 1.
[0044] The barrier cover 6 can be reinforced by the fastening ring 8, thereby ensuring the service life of the barrier cover 6.
[0045] The barrier cover 6 is configured as two layers. The size of the first barrier cover 6 is smaller than that of the second barrier cover 6. The first barrier cover 6 is slidably connected to the inside of the overflow well body 1. The bottom of the second barrier cover 6 abuts against the top of the overflow well body 1. The outer side of the first barrier cover 6 is fixedly connected to the inside of the fastening ring 8.
[0046] By setting the barrier cover 6 in two layers, the first layer barrier cover 6 can enter the overflow well body 1, so that the water flow can completely enter the overflow well body 1, and the second layer barrier cover 6 can restrict the position of the barrier cover 6.
[0047] By preventing the first layer of barrier cover 6 from entering the overflow well body, the position of barrier cover 6 will not be deflected. The setting of the retaining ring 8 can increase the stability of barrier cover 6, thereby ensuring the service life of barrier cover 6. The sliding connection between retaining ring 8 and the inside of overflow well body 1 allows retaining ring 8 to enter the inside of overflow well body 1, thereby restricting the position of barrier cover 6. Thus, barrier cover 6 can completely block the opening of overflow well body 1, thereby blocking impurities such as branches.
[0048] Among them, the radial hole 3 is positioned downwards, and the end of the guide pipe 2 away from the overflow well body 1 is angled slightly downwards.
[0049] By setting the radial hole 3 downwards, the soil above will not enter the interior of the diversion pipe 2, thus ensuring the smooth use of the diversion pipe 2. The downward orientation of the end of the diversion pipe 2 can increase the speed of water flow, thereby increasing the speed at which the water is absorbed by the soil.
