Description

Technical Field

[0001] The present invention relates to the technical field of permeable parking systems, and particularly to an outdoor permeable parking space for improving river water environment and a construction method thereof. Background Art

[0002] Cities can be like sponges, having good "elasticity" in adapting to environmental changes and coping with natural disasters. The international general term is "construction of low-impact development rainwater systems". When it rains, they absorb, store, infiltrate, and purify rainwater. When needed, the stored water is released and utilized to achieve the free migration of rainwater in the city. Permeable parking spaces are a relatively commonly used low-impact development technology. Permeable parking spaces use permeable materials to replace concrete, asphalt, floor tiles, etc. used in traditional parking lots, enabling rainwater to infiltrate in situ, reducing the runoff coefficient of the underlying surface, and conforming to the development trend of sponge cities.

[0003] After retrieval, a Chinese patent discloses an outdoor parking space system based on the concept of sponge city (publication number CN106917522B). When it rains, rainwater enters the first water storage layer through the permeable holes of the parking platform for regulation; then, the rainwater slowly flows downward through the purification and filtration layer into the second water storage layer. Under the filtration of the purification and filtration layer, the water quality entering the second water storage layer is greatly improved. The rainwater further infiltrates from the second water storage layer into the underground soil layer and finally converges into the groundwater. However, the existing structure has poor water accumulation discharge effect and is prone to form rain floods due to water accumulation when the rainfall is large. Therefore, the technical personnel in this field provide an outdoor permeable parking space and a construction method based on sponge city to solve the problems raised in the above background art.

[0053] During the implementation process, the upper part of the support plate 306 is used for vehicle parking. Rainwater can pass through the support plate 306 and enter the second planting layer 304 to water the planted plants. At the same time, the excess rainwater seeps downward into the interior of the second gravel layer 3217. And the rainwater can directly drip into the first planting layer 2 to water the plants, effectively utilizing the rainwater resources and effectively preventing the situation of rain floods, meeting the development needs of sponge cities.

[0061] Embodiment 2

[0062] In the present invention, preferably, the permeation assembly 31 includes a water permeable pipe 3101 provided on the inner wall of the first gravel layer 303.

[0063] In the present invention, preferably, the surface of the water guide pipe 3103 is provided with evenly distributed through holes 3105. A soil retaining cloth 3104 is sleeved on the surface of the water guide pipe 3103, and the soil retaining cloth 3104 blocks the through holes 3105.

[0064] During the implementation process, the water permeable pipe 3101 can absorb the rainwater permeated in the first gravel layer 303, so that the rainwater is collected inside the water permeable pipe 3101 and guided to the first planting layer 2 for irrigation. The coaxial arrangement of the water permeable pipe 3101 and the guide pipe 3204 with the guide pipe 3204 located inside the water permeable pipe 3101 can prevent the leakage of rainwater inside the guide pipe 3204. The leaked rainwater can be intercepted inside the water permeable pipe 3101 and exported together, ensuring a good flood discharge effect;

[0065] The setting of the soil retaining cloth 3104 is used to prevent the soil inside the first planting layer 2 from passing through the through holes 3105 and entering the inside of the water guide pipe 3103, and the water inside the water guide pipe 3103 can penetrate through the through holes 3105 to the deep part of the first planting layer 2, improving the water storage effect of the first planting layer 2.

[0066] The present invention also discloses a construction method for an outdoor permeable parking space based on a sponge city, including the following steps:

[0067] S1. During construction, first bury the drainage pipe 101 in the base layer 1, and then install two groups of partition plates 202, and then lay the first anti-filter geotextile 201 between the two groups of partition plates 202;

[0068] S2. Lay the second anti-filter geotextile 203, and install and connect the corresponding pipes of the permeation assembly 31 and the anti-internal waterlogging assembly 32;

[0069] S3. Lay the first gravel layer 303 and the second gravel layer 3217 in sequence, and fill the first planting layer 2 above the two groups of partition plates 202;

[0070] S4. Install the partition block 301 and the support block 305 above the second gravel layer 3217, then fill the second planting layer 304, and finally install the support plate 306 and the grille 307.

[0071] The working principle of the present invention: During construction, first bury the drainage pipe 101, and then install the partition board 202 and lay the first anti-filter geotextile 201. After installing the partition board 202, lay the second anti-filter geotextile 203. After installing the corresponding pipes of the permeation component 31 and the anti-internal waterlogging component 32, lay the first gravel layer 303 and the second gravel layer 3217 in sequence. Fill the first planting layer 2 above the two partition boards 202. Install the support block 305 and the partition block 301 above the second gravel layer 3217, then fill the second planting layer 304, and finally install the support plate 306.

[0072] The upper part of the support plate 306 is used for vehicle parking. Rainwater can pass through the support plate 306 and enter the second planting layer 304 to irrigate the planted plants. At the same time, the excess rainwater seeps downward into the interior of the second gravel layer 3217, and the rainwater can directly drip into the interior of the first planting layer 2 to irrigate the plants, effectively utilizing the rainwater resources and effectively preventing the situation of rain floods, meeting the development needs of sponge cities. With the mutual cooperation of the anti-internal waterlogging component 32 and the permeation component 31, the rainwater can be effectively adsorbed and collected. The first planting layer 2, the second planting layer 304, the first gravel layer 303 and the second gravel layer 3217 can be used for water storage to improve the flood resistance effect. At the same time, the excess rainwater can be timely introduced into the interior of the drainage pipe 101 through the anti-internal waterlogging component 32 and discharged. The filtration through the first planting layer 2, the second planting layer 304, the first gravel layer 303 and the second gravel layer 3217 can prevent the discharged rainwater from containing a large amount of impurities and causing blockage, ensuring the smoothness of the flood discharge pipe.

[0073] The above has described a detailed implementation example of the present invention, but the content described is only the preferred implementation example of the present invention and cannot be considered as limiting the implementation scope of the present invention. All equivalent changes and improvements made according to the application scope of the present invention should still fall within the patent coverage scope of the present invention.
