The plurality of pairs of side grooves 18 are located between every two adjacent grass planting grids 23. A second geotextile 19 is arranged on the inner wall of the side groove 18. A side pipeline 20 is arranged at a position inside the second geotextile 19. The side pipeline 20 is communicated with the main pipeline 16. A plurality of drip irrigation holes 21 are arranged at equal intervals on the surface of the side pipeline 20. Water inlet grooves 22 are formed on the side wall surfaces of the grass planting grids 23 on both sides of the side pipeline 20.
[0026] Combined with Figure 2 , the inside of the outer box 11 above the partition 12 should be filled with a gravel layer. The inside of the grass planting grid 23 can be filled with plain soil or a gravel layer. The lower part of the partition 12 at the bottom is a water seepage layer.
[0027] During heavy rain, external rainwater enters the inside of the outer box 11 through the grass planting grids 23 and the water inlet grooves 22. After double filtration through the gravel layer and the geotextile, it enters the bottom of the outer box 11 to complete the water purification work. Then, the water pump 14 will pump the purified water into the water storage tank 1 for storage, in case of watering during subsequent dry weather. If the water storage tank 1 cannot store the water when the rainfall is too large, the water in the water storage tank 1 can be pumped into the municipal pipe network through the first water diversion pipe 4.
[0028] Example 2
[0029] As Figure 4 shown, different from Example 1, in a grass planting device for sponge city of the present utility model, a plurality of evenly distributed fixing parts 27 are arranged at the bottom of the frame body 6. The bottoms of the fixing parts 27 can be inserted into the gravel layer. By arranging the fixing parts 27, the grass planting component 10 can be stably fixed inside the gravel layer.
[0030] Embodiment 3
[0031] As Figure 1 shown, different from Embodiment 2, in a grass-planting device for sponge city of the present utility model:
[0032] A water storage tank 1 is arranged at a position on one side of the outer box 11. A solar panel 2 is arranged on the top of the water storage tank 1. A battery pack 5 is installed on the surface of one side wall of the water storage tank 1. The solar panel 2 is electrically connected to the battery pack 5. By setting the solar panel 2, the battery pack 5 in the structure can be powered, so as to power the rest of the electrical appliances (such as the water pump 14) in the device, achieving the effect of energy conservation and environmental protection.
[0033] An observation board 3 is vertically arranged on the surface of one side wall of the water storage tank 1. The observation board 3 is made of transparent material. A first water inlet pipe 4 is arranged at a position on one side of the observation board 3. The water quantity inside the water storage tank 1 can be observed by using the observation board 3. The excess water in the water storage tank 1 can be pumped into the municipal pipe network through the first water inlet pipe 4.
[0034] A water outlet pipe 8 and a second water inlet pipe 7 are longitudinally distributed on one side surface of the water storage tank 1.

A plurality of main pipes are all communicated with the fixed pipe 9. Water pumps 14 are installed on the surfaces of the water outlet pipe 8 and the second water inlet pipe 7. When the external weather is dry, the staff can turn on the water pump 14 on the water outlet pipe 8 to pump the water inside the water storage tank 1 into the main pipe 16 on one side of the fixed pipe 9. At this time, the main pipe 16 will transport the water flow into the side pipe 20 between several grass-planting grids 23, and discharge it through the drip irrigation holes 21 on the side pipe 20. The discharged water will penetrate through the second geotextile 19 and enter the water inlet groove 22, realizing the irrigation of the plant roots inside the grass-planting grids 23. This design can accurately wet the soil in each grass-planting grid 23 in the grass-planting assembly 10, with uniform irrigation, and at the same time can save water consumption. Even when the weather is dry and the sun is shining, compared with the traditional spraying method, the amount of water evaporated by the sun heat will be much less.
[0035] Embodiment 4
[0036] Combined Figures 2 to 4 with, different from Embodiment 3, in a grass-planting device for sponge city of the present utility model, a plurality of grass-planting assemblies 10 are installed inside the outer box 11. First clamping blocks 24 and second clamping blocks 25 are respectively arranged at the front and rear positions of the grass-planting assemblies 10. Adjacent two grass-planting assemblies 10 are clamped through the first clamping blocks 24 and the second clamping blocks 25. Through the cooperation of the first clamping blocks 24 and the second clamping blocks 25, adjacent two grass-planting assemblies 10 can be spliced together, and the structural design is convenient for installation.
[0037] The working principle of the grass planting device for sponge city provided by the utility model is as follows:
[0038] Step 1: When the weather outside is dry, the staff can turn on the water pump 14 on the water outlet pipe 8 to extract the water inside the water tank 1 to the main pipe 16 on the side of the fixed pipe 9. At this time, the main pipe 16 will transport the water flow to the side pipe 20 between the grass grids 23, and discharge it through the drip irrigation holes 21 on the side pipe 20. The discharged water will penetrate the second geotextile 19 and enter the water inlet trough 22 to irrigate the plant roots inside the grass grid 23. This design can accurately moisten the soil of each grass grid 23 in the grass component 10, irrigate evenly, and save water. Even when the weather is dry and the sun is exposed, the amount of water evaporated by the sun's heat will be much less than that of the traditional spraying method;
[0039] The second step: on rainy days, external rainwater enters the outer box 11 through the grass grid 23 and the water inlet trough 22, and enters the bottom of the outer box 11 after being filtered through the gravel layer and the double layer of geotextile, completing the water purification work. After that, the water pump 14 will pump the clean water into the water storage tank 1 for storage in preparation for watering in subsequent dry weather. If the rainfall is too heavy and the water storage tank 1 cannot store water, the water in the water storage tank 1 can be pumped into the municipal pipe network through the first water diversion pipe 4. The structural design facilitates the purification and storage of water.
