Such systems often only focus on collection, purification and discharge. Even if the collected wetland water resources are used, they are limited to greening irrigation. During the irrigation process, water resources infiltrate into groundwater, which will gradually cause a shortage of surface water resources and is therefore not sustainable.

[0017] The technical scheme in the embodiment of the present invention will be described below in conjunction with the accompanying drawings in the embodiment of the present invention:
[0018] As shown in the figure, the utility model proposes a sponge-type ecological parking lot suitable for a wetland park. There are a plurality of neatly arranged parking spaces 4 in the parking lot 3, each parking space 4 is a collection and purification module, and a purification layer 42 of the purification module is in the middle of the parking space 4. The cross section of the purification layer 42 is rectangular, and the top layer of the purification layer 42 is surrounded by a water-impermeable cement concrete structure 41. Below the cement concrete structure 41 is an ordinary original soil layer 6. The end of the cement concrete structure 41 away from the center of the parking space 4 is higher than the end close to the center of the parking space 4, forming a slope of the cement concrete structure 41 toward the center of the purification layer 42, and the slope is 2%-3%. The upper surface of the purification layer 42 is not higher than the lowest point of the surface layer of the cement concrete structure 41, ensuring that rainwater can flow from the parking lot 3 to the purification layer 42 in the middle of the parking space 4. The purification layer 42 is composed of a plant layer 411, a planting soil layer 412, a permeable non-woven fabric 413, a gravel layer 414, and a permeable Non-woven fabric 413, volcanic rock layer 415, water-permeable non-woven fabric 413, stone layer 416, waterproof fabric 7 is set at the bottom and side of purification layer 42, so that the water of purification layer 42 will not spread to the surrounding ordinary original soil layer 6, and a water resource collection pipe 31 is set through the stone layer 416 of the lowest layer of purification layer 42. There is an opening 311 at the position where the water resource collection pipe 31 overlaps with the stone layer 416, and there is no opening in the area where the water resource collection pipe 31 overlaps with the ordinary original soil layer 6, ensuring Water can be discharged into the ditch 1 only after being purified by the purification layer 42; the water resource collection pipe 31 can be a perforated HDPE pipe, the opening 311 is a plum blossom-shaped annular staggered hole, the hole diameter is 5mm-10mm, the hole spacing is 10cm-15cm, the diameter of the collection pipe 31 is 50cm (SDR value is 13.6 or 11), and a medium-coarse sand layer 32 is arranged around the collection pipe 31. The collection pipe 31 runs through the parking spaces 4 in the same row, and the water outlet end of the collection pipe 31 is connected to the bottom of the ditch 1. The outer edge of the cement concrete structure 41 is the outer edge of the parking space 4. Rainwater flows from the outer edge of the cement concrete structure 41 along the slope of the cement concrete structure 41 to the purification layer 42, first passes through the plant layer 411 layer by layer to reach the stone layer 416. Since the side and bottom of the purification layer 42 are isolated by waterproof cloth 7, the rainwater enters the collection pipe 31 after passing through the stone layer 416 and is discharged into the ditch 1. The end section of the ditch 1 is connected to the landscape water body 2 through the outlet pipe 13, and the water purified by the parking lot is discharged to the landscape water body 2.
[0019] The plant layer 411 is mixed with warm-season grass species (such as 1-3 species of buffalo grass, zoysia grass, and bermudagrass) and cool-season grass species (such as 1-3 species of bluegrass, tall fescue, and ryegrass). The planting soil layer 412 is a mixture of garden soil, peat soil, perlite, and organic fertilizer in a ratio of 50:35:10:5. The particle size of the gravel layer 414 is controlled at 1cm-3cm, the particle size of the volcanic rock layer is controlled at 3cm-5cm, and the particle size of the block stone layer 416 is controlled at 5cm-8cm. After the rainwater or flushing water is filtered and purified by the above-mentioned purification module layer by layer, it enters the collection pipe 31 through the opening 311 of the collection pipe 31 and is finally discharged into the closed ditch 1, hereinafter referred to as ditch 1. The ditch 1 is concave to ensure that the purification layer 42 The collected water resources can flow into the ditch 1 by gravity. The top of the ditch 1 is a permeable concrete pavement layer 12, and the bottom and the surrounding sides are impermeable cement concrete structures 11. Above the permeable concrete pavement layer 12 is a slope protection vegetation layer 14. The slope protection vegetation layer 14 is mainly composed of herbaceous plants, which are perennial herbaceous plants (2-4 species are selected according to the local climate). A stone pile 15 is also arranged in the slope protection vegetation layer 14 on one side, and a permeable retaining wall 9 is arranged between the slope protection vegetation layer 14 and the road 8 on the other side. The permeable retaining wall 9 is made of permeable bricks and is arranged on the side close to the driving road 8. A PVC drainage pipe 91 is arranged in the middle of the retaining wall, and a drainage hole is opened on the PVC drainage pipe 91. The diameter of the drainage hole is 2cm-3cm. On the one hand, this ditch 1 collects water resources filtered and purified by the purification layer 42. When the purification module cannot be normally consumed in a short period of time, the water resources will flow directly from the surface to the ditch 1, and in the process, it will flow through the stone pile 15, the slope protection vegetation layer 14, and the permeable concrete pavement layer 12. On the other hand, an impermeable ditch 81 is provided between one side of the road 8 and the permeable retaining wall 9. During the rainy season, rainwater on the road 8 will pass through the impermeable ditch 81 for preliminary sedimentation. After reaching a certain liquid level, it will seep out through the permeable retaining wall 9. As the liquid level gradually rises, it will eventually be discharged through the PVC drainage pipe 91. The infiltrated or discharged rainwater enters the slope protection vegetation layer 14, and finally enters the ditch 1 through the permeable concrete layer 17. All collected water resources will enter the landscape water body 2 inside the wetland park through the outlet pipe 13. The outlet pipe port 131 is set upstream of the landscape water body 2. The outlet pipe 13 is made of HDPE corrugated pipe with a diameter greater than 60 cm. The landscape water body 2 can be purified by the water ecosystem 21 , which includes aquatic plants, aquatic animals, and aquatic microorganisms, so that the landscape water body 2 can meet the quality requirements of the water body under the deep purification of the water ecosystem 21 .
[0020] Furthermore, a single-phase flow negative pressure pumping system is arranged in the underground of the parking lot 3, including an inlet pipe 51, a negative pressure device 5, a distribution branch pipe 52, and a vehicle washing device 53. When a vehicle needs to be washed, the system uses the negative pressure device 5 to draw water resources in the downstream landscape water body 2 through the inlet pipe 51 into the negative pressure device 5, and distributes it to a specific parking space through the distribution branch pipe 52. The water resources after washing the vehicle by the vehicle washing device 53 will infiltrate into the purification module again for collection, thereby finally forming a closed-loop parking lot water resource recycling system.
[0021] The above embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
