Abstract
Description
Technical Field
[0001] This utility model relates to the field of garden rainwater treatment technology, and in particular to a ground rainwater infiltration and collection structure. Background Technology
[0002] Currently, some residential areas, urban green spaces, and parks have landscape systems built within them. These landscapes typically include walkways for pedestrians, with land on both sides for planting various plants (such as grasses, shrubs, and trees). Currently, some landscape designs feature a significant elevation difference between the land and the walkway, with the land being considerably higher than the walkway. These are connected by retaining stones. However, this design, with retaining stones protruding from both sides of the walkway, necessitates the use of highly permeable paving or buried drainage pipes, increasing construction costs.
[0003] In some garden designs, the land and the walkway are basically level, and a ditch is designed in the depression between the land and the walkway. When it rains, the surface water can flow into the ditch for drainage. In this structure, because the walkway is not wide, the water on the walkway can flow into the ditch quickly. The walkway can be paved with ordinary concrete or stone slabs, which reduces the construction cost of the walkway.
[0004] However, based on the above-mentioned plan where the land and the walkway are basically level, when it rains, the water on the land surface will carry silt and sand. This silt and sand will enter the drainage ditch and cause siltation and blockage, which will lead to poor drainage in the long run. Utility Model Content
[0005] The purpose of this invention is to provide a ground rainwater infiltration and collection structure that can reduce the amount of silt entering the ditch and causing poor drainage.
[0006] To achieve the above objectives, a ground rainwater infiltration and collection structure is provided, comprising a land body, a ditch, and a walkway body arranged sequentially. The top surface of the land body is flush with the top surface of the walkway body, and the top surface of the ditch is lower than the top surface of the walkway body. A filter frame is provided on the top of the ditch, and a first gravel layer is laid inside the filter frame. The top surfaces of the filter frame and the first gravel layer are not higher than the top surface of the walkway body. A blind pipe drainage structure is provided within the land body, and the outlet end of the blind pipe drainage structure is connected to the inner wall of the ditch. A water storage structure is also provided within the land body, and the water storage structure is connected to the bottom of the ditch.
[0007] According to the aforementioned ground rainwater infiltration collection structure, the bottom of the filter frame is provided with a positioning part, which is inserted into the water ditch, and the side wall of the filter frame and the bottom of the positioning part are both provided with a first infiltration hole.
[0008] According to the aforementioned ground rainwater infiltration and collection structure, the blind pipe drainage structure includes a blind pipe body, a geotextile layer, and a second gravel layer. The outlet end of the blind pipe body is connected to the inner wall of the ditch. The geotextile layer is covered on the outside of the blind pipe body, and the second gravel layer is covered on the outside of the geotextile layer.
[0009] According to the aforementioned ground rainwater infiltration and collection structure, the water storage structure includes a water storage tank and a drainage pipe. The water storage tank is located within the main body of the land. The inlet end of the drainage pipe is connected to the bottom of the ditch, and the outlet end of the drainage pipe is connected to the side wall of the water storage tank. The inlet end of the drainage pipe is higher than the outlet end.
[0010] According to the aforementioned ground rainwater infiltration and collection structure, the top of the water storage tank is provided with a concrete roof slab, and the concrete roof slab has a stepped inspection port.
[0011] According to the aforementioned ground rainwater infiltration and collection structure, a cover is provided inside the inspection port, the top surface of the cover is not lower than the top surface of the concrete roof slab, and a trash can or road sign is provided on the top of the cover.
[0012] According to the aforementioned ground rainwater infiltration and collection structure, a grating plate is installed inside the inspection port, the top surface of the grating plate is lower than the top surface of the concrete roof slab, and a planting box is installed on the top of the cover. The bottom of the planting box is inserted into the inspection port and is provided with a second seepage hole.
[0013] According to the aforementioned ground rainwater infiltration and collection structure, the filter frames are configured as multiple frames arranged sequentially along the ditch, and the longitudinal projections of the joints of adjacent filter frames are staggered from the longitudinal projections of the inlet end of the drainage pipe and the longitudinal projections of the outlet end of the blind pipe drainage structure.
[0014] Beneficial effects: As described above, the main body of the land and the main body of the walkway are designed to be flush. The filter frame and the first gravel layer can cover the top of the ditch, preventing pedestrians from stepping into the ditch and getting injured. The filter frame and the first gravel layer can also prevent the ditch from being exposed, reducing the breeding of mosquitoes and the backflow of odors. When rain or irrigation causes water to accumulate on the ground, the water can flow to the ditch and be filtered and infiltrated by the first gravel layer, reducing the amount of silt and other impurities entering the ditch and causing blockages, ensuring smooth drainage. When a lot of silt accumulates on the first gravel layer and affects the filtration performance, the filter frame can be directly removed and the silt on the first gravel layer can be cleaned, making it easier to maintain.

[0025] Reference Figure 1-4A ground rainwater infiltration and collection structure includes a land body 10, a ditch 20, and a walkway body 30 arranged sequentially. The top surface of the land body 10 is flush with the top surface of the walkway body 30. The top surface of the ditch 20 is lower than the top surface of the walkway body 30. A filter frame 40 is installed on the top of the ditch 20, and a first gravel layer 41 is laid inside the filter frame 40. The top surfaces of the filter frame 40 and the first gravel layer 41 are not higher than the top surface of the walkway body 30. A blind pipe drainage structure 50 is installed inside the land body 10, and the outlet end of the blind pipe drainage structure 50 is connected to the inner wall of the ditch 20. A water storage structure 60 is also installed inside the land body 10, and the water storage structure 60 is connected to the bottom of the ditch 20.
[0026] As described above, the land body 10 and the walkway body 30 are designed to be flush. The filter frame 40 and the first gravel layer 41 can cover the top of the ditch 20, preventing pedestrians from stepping into the ditch 20 and getting injured. The filter frame 40 and the first gravel layer 41 also prevent the ditch 20 from being exposed, reducing the breeding of mosquitoes and the backflow of odors. When rain or irrigation causes water to accumulate on the ground, the water can flow to the ditch 20 and be filtered by the first gravel layer 41 before seeping to the bottom of the ditch 20, reducing the entry of silt and other impurities into the ditch 20 and ensuring smooth drainage. When a lot of silt accumulates on the first gravel layer 41 and affects the filtration performance, the filter frame 40 can be directly removed and the silt on the first gravel layer 41 can be washed off, making it easier to maintain. In addition, no drainage structure is required in the walkway body 30, which simplifies the structure of the walkway body 30 and reduces its construction cost.
[0027] In this design, a positioning part 42 protrudes from the bottom of the filter frame 40 and is inserted into the water ditch 20. First seepage holes 43 are provided on both the side wall of the filter frame 40 and the bottom of the positioning part 42. This structure facilitates the positioning of the filter frame 40 and allows water to seep into the water ditch 20.
[0028] In this scheme, the blind pipe drainage structure 50 includes a blind pipe body 51, a geotextile layer 52, and a second gravel layer 53. The blind pipe body 51 is inserted into one side of the ditch 20, and the outlet end of the blind pipe body 51 is connected to the inner wall of the ditch 20. The geotextile layer 52 is covered on the outside of the blind pipe body 51, and the second gravel layer 53 is covered on the outside of the geotextile layer 52. This structure allows excess water stored in the soil body 10 to seep out, preventing root rot and other problems for plants.
[0029] In this design, the water storage structure 60 includes a water storage tank 61 and a drainage pipe 62. The water storage tank 61 is located within the main land structure 10. The inlet end of the drainage pipe 62 is connected to the bottom of the ditch 20, and the outlet end of the drainage pipe 62 is connected to the side wall of the water storage tank 61. The inlet end of the drainage pipe 62 is higher than the outlet end. Water flowing into the ditch 20 can flow into the water storage tank 61 through the drainage pipe 62 for irrigation when plants are short of water, thus reducing the consumption of municipal water.
[0030] In this design, a concrete roof slab 63 is provided on the top of the water storage tank 61, and the concrete roof slab 63 has a stepped access port 631. Tools can be inserted into the water storage tank 61 through the access port 631, or personnel can enter the water storage tank 61 to carry out maintenance and cleaning.
[0031] If soil is covered on top of the concrete roof slab 63 and plants are planted, the plants on top will grow significantly worse than those in other locations due to the thinness of the soil covering the concrete roof slab 63, resulting in a poor aesthetic appearance of the garden landscape. Therefore, this utility model provides the following two design structures.
[0032] Reference Figure 3 In some embodiments, a cover 64 is provided inside the access port 631, the top surface of the cover 64 being no lower than the top surface of the concrete roof slab 63, and a trash can 65 is provided on the top of the cover 64. The trash can 65 facilitates the collection of garbage, and the cover 64 completely seals the access port 631, preventing debris from falling into the water storage tank 61. Furthermore, structures such as road signs can also be installed on the top of the cover 64.
[0033] Reference Figure 4 In some embodiments, a grating plate 66 is provided inside the inspection port 631, the top surface of the grating plate 66 being lower than the top surface of the concrete roof slab 63, and a planting box 67 is provided on the top of the cover 64. The bottom of the planting box 67 is inserted into the inspection port 631 and is provided with a second drainage hole. Landscape plants can be planted in the planting box 67. Excess water in the planting box 67 can flow into the water storage tank 61 through the second drainage hole and the grating plate 66; and the moisture in the water storage tank 61 can rise to the bottom surface of the planting box 67, which can promote the downward root growth of the landscape plants and improve their drought resistance and growth.
[0034] As shown above, the top surface of the concrete roof slab 63 is flush with the top surface of the walkway body 30, providing a functional platform that does not require direct soil covering for planting. This avoids the problem of inconsistent plant growth and also improves the overall aesthetics of the design.
[0035] In the above scheme, multiple filter frames 40 are arranged sequentially along the ditch 20. The longitudinal projection of the joint of adjacent filter frames 40 is staggered from the longitudinal projection of the inlet end of the drain pipe 62 and the longitudinal projection of the outlet end of the blind pipe drainage structure 50, so that the inlet end of the drain pipe 62 and the outlet end of the blind pipe drainage structure 50 are offset from the direct bottom of the joint of adjacent filter frames 40. This can avoid the following situation: when there is a gap between adjacent filter frames 40, mud, sand and other debris will directly pass through the gap and fall into the ditch 20, and then directly enter the blind pipe body 51 or the drain pipe 62.
[0036] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
