[0021] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0022] This utility model provides a rain garden with rapid infiltration efficiency through improvements. The technical solution of this utility model is as follows:

[0023] like Figure 1 As shown, a rain garden with rapid infiltration efficiency includes a base layer 1, a water storage tank 2 on one side of the base layer 1, a pit layer 3 inside the base layer 1, and several water outlet holes 4 on the surface of the pit layer 3. The water outlet holes 4 make it easier for rainwater to penetrate into the soil and improve the infiltration efficiency. An overflow pool 5 is set inside the pit layer 3, and a connecting pipe 6 is set on one side of the overflow pool 5. The connecting pipe 6 is connected to the inner cavity of the water storage tank 2, and the water is transported to the water storage pool for storage through the connecting pipe 6, which effectively utilizes rainwater resources, avoids waste, and provides a backup irrigation water source for the dry season. A spraying device 7 is set on the base layer 1, and a pumping pipe 8 is set on the water storage tank 2, which is connected to the spraying device 7.

[0024] like Figure 2As shown, in one embodiment, the gap between the overflow pool 5 and the foundation pit is filled with a layer of gravel 9, and a layer of planting soil 10 is filled on top of the gravel layer 9. The gravel layer 9 and the planting soil layer 10 themselves, as well as the gap between them, are left to facilitate the rapid infiltration of rainwater into the garden and accelerate the water penetration speed.

[0025] In one embodiment, a filter screen 11 is provided on the top of the overflow pool 5, and a drain plate 12 is provided on the top of the filter screen 11. A plurality of drain holes are provided through the surface of the drain plate 12.

[0026] like Figure 3 and Figure 4 As shown, in one embodiment, the spraying device 7 includes a telescopic rod 71 set on the base layer 1. A water pump 72 is set at the top of the telescopic rod 71, and a rotating nozzle 73 is set at one end of the water pump 72. The water pump 72 and the rotating nozzle 73 are similar to the irrigation nozzles commonly used in irrigation in the prior art, and will not be described in detail here. The telescopic rod 71 includes a bottom sleeve rod 711 set on the base layer 1. An adjusting rod 712 is slidably connected to the inner cavity of the bottom sleeve rod 711. The top tube of the adjusting rod 712 is connected to the water pump 72. The bottom sleeve rod 711 and the adjusting rod 712 can realize the raising and lowering of the water pump 72 and the rotation height, thereby changing the irrigation range.

[0027] In one embodiment, the surface of the bottom sleeve 711 is provided with a plurality of adjustment holes 713, which are equidistantly distributed. The surface of the adjustment rod 712 is provided with a positioning hole 714. A positioning spring 715 is fixedly connected to the inner wall of the positioning hole 714. A positioning block 716 is slidably connected to the inner wall of the positioning hole 714. The size of the positioning block 716 is adapted to the inner diameter of the adjustment hole 713. The positioning block 716 is fixedly connected to one end of the positioning spring 715.

[0028] The specific working method is as follows: When the rain garden with rapid infiltration efficiency is used, the base layer 1 and the water storage tank 2 are set up at the predetermined location. After the base layer 1 is excavated, the foundation pit layer 3 is filled. After the foundation pit layer 3 is filled, the overflow pool 5 is set up, and the overflow pool 5 is connected to the water storage tank 2 using the connecting pipe 6. The gap between the overflow pool 5 and the foundation pit layer 3 is filled with a gravel layer 9 and a planting soil layer 10 respectively. The gravel layer 9 is placed below the planting soil layer 10. Then, the filter screen 11 and the drainage plate 12 are placed on the overflow pool 5 in sequence to complete the installation. In subsequent use, the water inlet and outlet holes of the drainage plate 12 can help rainwater infiltrate quickly in the garden. The rapid water infiltration speed prevents water from stagnating on the surface and causing water accumulation, which helps reduce the occurrence of floods and soil erosion. The filter screen 11 can effectively intercept impurities, silt and other particles in rainwater. The water outlet 4 on the foundation pit allows rainwater to penetrate into the soil more easily, improving infiltration efficiency. The overflow pool 5 can transport the water to the storage tank through the connecting pipe 6, effectively utilizing rainwater resources, avoiding waste, and providing a backup irrigation water source for the dry season. The sprinkler device 7 can spray water quantitatively according to the needs of plants, avoiding water waste and effectively saving water.
