Description

Technical Field

[0001] This utility model relates to the field of underground water storage and purification technology, specifically a permeable concrete underground water storage and purification structure. Background Technology

[0002] With the acceleration of urbanization and the continuous increase in the proportion of paved surfaces, the stormwater runoff coefficient has increased, leading to increasingly prominent problems such as urban flooding, insufficient groundwater recharge, and initial stormwater pollution. In response to the concept of "sponge city" construction, permeable water storage structures have become one of the core technologies for solving these problems, requiring multiple functions such as permeability, purification, water storage, load-bearing capacity, and discharge.

[0003] The existing publicly available technical solution CN217810298U discloses a water-retaining pavement structure, including a clear water tank, a compacted soil base, a plain concrete subbase, a waterproof geotextile, a water-retaining module layer, a long-filament woven geotextile, a graded crushed stone base, a coarse sand leveling layer, and a prefabricated permeable concrete surface layer. This utility model features a water-retaining module layer to store water on the pavement. Excess water can then be transported to the municipal stormwater network via an overflow pipe, preventing rainwater accumulation on the pavement and affecting vehicle traffic. Water from the water-retaining module layer can be transported to the clear water tank via connecting pipes. After filtration and purification, the water is discharged through a rainwater utilization pipe for reuse. This utility model's pavement structure simultaneously considers load-bearing capacity, permeability, water purification, water storage, rainwater reuse, cooling, and noise reduction functions.

[0004] However, the existing technical solution still has some shortcomings in actual implementation. The device simply connects the water storage module and the clear water tank through connecting pipes. During heavy rain, rainwater in the water storage module continuously flows into the clear water tank through the pipes, which can easily cause the clear water tank to overflow. Excess rainwater seepage may also pollute the surrounding soil. This passive connection design results in a serious disconnect between rainwater storage and reuse, and the rainwater reuse efficiency can only be maintained at a low level, which limits the resource utilization value of water resources. Utility Model Content

[0005] Given that the existing technology simply connects the water storage module to the clear water tank via a connecting pipe, during heavy rain, rainwater continuously flows from the water storage module into the clear water tank through the pipe, which can easily cause the clear water tank to overflow. Excess rainwater seepage may also pollute the surrounding soil. This passive connection design results in a serious disconnect between rainwater storage and reuse, and the rainwater reuse efficiency can only be maintained at a low level, which limits the resource utilization value of water resources.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A permeable concrete underground water storage and purification structure includes a purification component; a drainage component for discharging excess rainwater; and a water storage component for storing purified water.

[0008] The purification component includes: a fixing plate; and a mesh plate disposed on the upper end of the fixing plate;

[0009] The drainage assembly includes: a drainage groove formed on the surface of the fixed plate; and an overflow pipe connected to the left end of the drainage groove;

[0010] The water storage assembly includes: a first water storage tank installed at the lower end of the fixed plate; and a connecting pipe connected to the front end of the first water storage tank.

[0011] As a further embodiment of this utility model: the purification component further includes: a coarse sand filter layer and a water-permeable layer; the coarse sand filter layer is disposed at the upper end of the mesh plate; the water-permeable layer is disposed at the upper end of the coarse sand filter layer.

[0012] As a further embodiment of this utility model: the interior of the coarse sand filter layer is filled with quartz sand, the particle size of which is smaller than that of the permeable layer, and an isolation cloth is laid at the bottom of the coarse sand filter layer.

[0013] As a further embodiment of this utility model: the purification component further includes: a filter cartridge; the filter cartridge is detachably installed inside the fixed plate, and the filter cartridge passes through the fixed plate.

[0014] As a further embodiment of this utility model: the drainage assembly further includes: a one-way valve and a municipal drainage pipe; the one-way valve is disposed on the surface of the overflow pipe; the municipal drainage pipe is connected to the end of the overflow pipe, and the municipal drainage pipe is connected to the overflow pipes that are evenly distributed in a dry group.

[0015] As a further embodiment of this utility model: the water storage component further includes: a support column; the support column is fixed inside the first water storage tank, the upper end of the support column is fixed to a fixing plate, and several groups of support columns are evenly distributed inside the first water storage tank.

[0016] As a further embodiment of this utility model: the water storage assembly further includes: a second water storage tank and a submersible pump; the second water storage tank is connected to the end of the connecting pipe; the submersible pump is fixed to the inside of the second water storage tank by external bolts.

[0017] As a further embodiment of this utility model: the water storage component further includes: a float switch and a water supply pipe; the float switch is installed on the inner wall of the second water storage tank; the water supply pipe is connected to the output end of the submersible pump.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This utility model forms a two-stage purification system from primary filtration to deep filtration by using a permeable layer, a coarse sand filter layer, and internally filled quartz sand, filter cartridge, and internal activated carbon in the purification component. The coarse sand filter layer intercepts large particulate impurities, while the filter cartridge adsorbs organic matter and heavy metals. Furthermore, the filter cartridge adopts a detachable design, which facilitates the replacement of the purification medium. This not only significantly improves the rainwater purification effect but also reduces the difficulty and cost of maintenance, solving the problems of poor purification and inconvenient maintenance in existing technologies.

[0020] 2. This utility model uses support columns in the water storage assembly fixed inside the first water storage tank and connected to a fixing plate at the top. Several sets of support columns are evenly distributed to form a stable support structure. This design significantly improves the overall load-bearing capacity and is suitable for vehicle traffic scenarios such as non-motorized vehicle lanes and parking lots, effectively solving the defects of insufficient load-bearing capacity in existing structures.

[0021] 3. This utility model forms a two-stage water storage space by using the first and second water storage tanks of the water storage component.

[0028] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Example 1: Please refer to Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a permeable concrete underground water storage and purification structure, including a purification component 1; a drainage component 2 for discharging excess rainwater; and a water storage component 3 for storing purified water.

[0031] Purification component 1 includes: a fixing plate 101; and a mesh plate 103 disposed on the upper end of the fixing plate 101;

[0032] The drainage assembly 2 includes: a drainage groove 202 formed on the surface of the fixed plate 101; and an overflow pipe 201 connected to the left end of the drainage groove 202;

[0033] The water storage component 3 includes: a first water storage tank 301 installed at the lower end of the fixed plate 101; and a connecting pipe 304 connected to the front end of the first water storage tank 301.

[0034] Specifically, the purification component 1 also includes: a coarse sand filter layer 102 and a water-permeable layer 104; the coarse sand filter layer 102 is disposed at the upper end of the mesh plate 103; the water-permeable layer 104 is disposed at the upper end of the coarse sand filter layer 102.

[0035] Furthermore, rainwater first comes into contact with the permeable layer 104 and seeps down to the coarse sand filter layer 102 below through the permeability of the permeable layer 104.

[0036] Specifically, the interior of the coarse sand filter layer 102 is filled with quartz sand, the particle size of which is smaller than that of the permeable layer 104, and an isolation cloth is laid at the bottom of the coarse sand filter layer 102.

[0037] Furthermore, the quartz sand filled inside the coarse sand filter layer 102 performs preliminary filtration of rainwater, intercepting large particles of impurities. The isolation cloth laid at the bottom prevents the quartz sand from being lost, and the surface of the isolation cloth has small holes so as not to obstruct rainwater.

[0038] Specifically, the purification component 1 also includes a filter cartridge 105; the filter cartridge 105 is detachably installed inside the fixed plate 101 and passes through the fixed plate 101.

[0039] Furthermore, the filter cartridge 105 is filled with activated carbon.

[0040] During use, when it rains, rainwater first comes into contact with the permeable layer 104 and seeps down to the coarse sand filter layer 102 below through the permeability of the permeable layer 104. The quartz sand filled inside the coarse sand filter layer 102 performs preliminary filtration of the rainwater, intercepting large particles of impurities. The isolation cloth laid at the bottom prevents the quartz sand from being lost. The isolation cloth has small holes on its surface, so it does not obstruct the rainwater. Therefore, the rainwater after preliminary filtration enters the fixed plate 101 through the isolation cloth and the perforated plate 103 set at the upper end of the fixed plate 101. The perforated plate 103 can prevent the construction of the coarse sand filter layer 102 from clogging the drainage channel 202 and the filter cartridge 105. At this time, the rainwater enters the filter cartridge 105 that penetrates the fixed plate 101 for deep purification.

[0041] In summary, this utility model forms a two-stage purification system from primary filtration to deep filtration through the permeable layer 104, coarse sand filter layer 102, and the internally filled quartz sand, filter cartridge 105, and internal activated carbon in the purification component 1. The coarse sand filter layer 102 intercepts large particulate impurities, while the filter cartridge 105 adsorbs organic matter and heavy metals. Furthermore, the filter cartridge 105 adopts a detachable design, which facilitates the replacement of the purification medium. This not only significantly improves the purification effect but also reduces the difficulty and cost of maintenance, solving the problems of poor purification and inconvenient maintenance in the existing technology.

[0042] Example 2: Please refer to Figures 1-5 This is the second embodiment of the present utility model.

[0043] Specifically, the drainage component 2 also includes: a one-way valve 204 and a municipal drainage pipe 203; the one-way valve 204 is disposed on the surface of the overflow pipe 201; the municipal drainage pipe 203 is connected to the end of the overflow pipe 201, and the municipal drainage pipe 203 is connected to several groups of evenly distributed overflow pipes 201.

[0044] Furthermore, excessive rainwater will flow into the drainage channel 202 opened on the surface of the fixed plate 101 and be discharged through the overflow pipe 201 connected to the left end of the drainage channel 202. The one-way valve 204 provided on the surface of the overflow pipe 201 can effectively prevent rainwater from flowing back.

[0045] Specifically, the water storage component 3 also includes: a support column 303; the support column 303 is fixed inside the first water storage tank 301, the upper end of the support column 303 is fixed to the fixing plate 101, and several groups of support columns 303 are evenly distributed inside the first water storage tank 301.

[0046] Furthermore, several sets of support columns 303 evenly distributed inside the first water storage tank 301 provide stable support for the fixed plate 101, thereby enhancing the load-bearing capacity of the permeable layer 104 to cope with vehicle traffic loads.

[0047] Specifically, the water storage component 3 also includes: a second water storage tank 302 and a submersible pump 305; the second water storage tank 302 is connected to the end of the connecting pipe 304; the submersible pump 305 is fixed to the inside of the second water storage tank 302 by external bolts.

[0048] Furthermore, the submersible pump 305 delivers the purified rainwater to the outside for reuse through the water delivery pipe 307 connected to its output end.

[0049] Specifically, the water storage component 3 also includes: a float switch 306 and a water supply pipe 307; the float switch 306 is installed on the inner wall of the second water storage tank 302; the water supply pipe 307 is connected to the output end of the submersible pump 305.

[0050] Furthermore, the float switch 306 is connected to the submersible pump 305 via a wire. When the water level reaches the set reuse height of the float switch 306, the float switch 306 triggers the submersible pump 305 to start.

[0051] In use, the deeply purified rainwater falls into the first water storage tank 301. Several sets of evenly distributed support columns 303 inside the first water storage tank 301 provide stable support for the fixed plate 101, thereby enhancing the load-bearing capacity of the permeable layer 104 to cope with vehicle traffic loads. When the rainwater stored in the first water storage tank 301 reaches a certain water level, it is transported through the connecting pipe 304 at its front end to the second water storage tank 302 at the end of the connecting pipe 304 for secondary storage. A float switch 306 installed on the inner wall of the second water storage tank 302 is connected to the submersible pump 305 via a wire. When the water level reaches the set reuse height of the float switch 306, the float switch 306... When the submersible pump 305 is triggered to start, the submersible pump 305 delivers the purified rainwater to the outside for reuse through the water pipe 307 connected to the output end. If there is excessive rainwater due to heavy rain or other situations, exceeding the processing capacity of the purification component 1 and the storage capacity of the water storage component 3, some rainwater will flow into the drainage channel 202 opened on the surface of the fixed plate 101 and be discharged through the overflow pipe 201 connected to the left end of the drainage channel 202. The one-way valve 204 set on the surface of the overflow pipe 201 can effectively prevent rainwater backflow. Finally, the rainwater is discharged into the municipal rainwater system through the municipal drainage pipe 203 connected to the end of the overflow pipe 201, thereby completing the entire process of water permeation, purification, water storage and excessive rainwater discharge.

[0052] In summary, this utility model uses support columns 303 in the water storage component 3 fixed inside the first water storage tank 301 and connected to the upper end of the fixing plate 101. Several sets of support columns 303 are evenly distributed to form a stable support structure. This design significantly improves the overall load-bearing capacity and can be adapted to vehicle traffic scenarios such as non-motorized vehicle lanes and parking lots, effectively solving the defects of insufficient load-bearing capacity in existing structures. This utility model forms a two-stage water storage space through the first water storage tank 301 and the second water storage tank 302 in the water storage component 3. With the help of the drainage trough 202, overflow pipe 201 and one-way valve 204 in the drainage component 2, it realizes the logic of priority storage and excess discharge. At the same time, the float switch 306 in the second water storage tank 302 is linked with the submersible pump 305 to automatically control rainwater reuse, which not only improves the water resource utilization rate, but also avoids flooding during rainstorms, solving the problem of disconnect between water storage and reuse in existing technologies.

Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.
