[0018] Please see Figure 1 , Figure 1 This is a cross-sectional structural diagram of a modular intelligent control type sunken green space system according to an embodiment of the present invention. The overall structure of the system includes components such as a permeable paving layer 100, a filter and purification layer 200, a water storage layer 300, an impermeable layer 400, and a perforated drainage pipe 500.

[0019] like Figure 1 As shown, the system consists of a permeable pavement layer 100, a filtration and purification layer 200, a water storage layer 300, and an impermeable layer 400, arranged from top to bottom. The permeable pavement layer 100 serves as the surface layer, allowing rainwater to infiltrate rapidly. The permeable pavement layer 100 can be constructed of permeable concrete or grass pavers. When grass pavers are used, a planting soil layer 110 is placed between the grass pavers and the filtration and purification layer 200. The grass pavers are used to plant water-purifying plants, such as reeds and calamus, to enhance the system's ecological function. Furthermore, the permeable pavement layer 100 can be equipped with temperature and humidity sensors 120 to monitor the temperature and humidity of the grass pavers, thereby facilitating the adjustment of the water-purifying plant growth and achieving intelligent control.

[0020] The filter and purification layer 200 is located below the permeable pavement layer 100 and is composed of prefabricated filter and purification modules 210. (See also...) Figure 2 and Figure 3 , Figure 2 This is a schematic diagram of the structure of a filtration and purification module provided in an embodiment of the present invention. Figure 3 For the reason Figure 2 The filtration and purification module forms an assembled structure. The filtration and purification module 210 includes, from top to bottom, a biochar-zeolite mixed layer, a nano-ceramic particle layer, and a coarse sand layer. Each layer is separated by geotextile to achieve step-by-step filtration and purification of rainwater. Specifically, in this embodiment, the thickness of the biochar-zeolite mixed layer can be set to 200 mm, the thickness of the nano-ceramic particle layer to 150 mm, and the thickness of the coarse sand layer to 100 mm. In other embodiments, the thickness of each filtration layer can be set according to actual needs, and no specific limitations are made here.

[0021] The water storage layer 300 is located below the filtration and purification layer 200 and is assembled from prefabricated water storage modules 310. The water storage layer 300 is equipped with a water level sensor 320 for real-time water level monitoring. Please refer to [link / reference]. Figure 4 , Figure 4 This is a schematic diagram of the structure of a water storage module provided in one embodiment of the present invention. The prefabricated water storage module 310 includes a honeycomb-shaped PP plastic water storage module, which includes a plate 311 and four water storage units 312. The plate is provided with water inlet holes (e.g., hexagonal holes) for allowing rainwater to enter and be stored inside the water storage units. The plate is also provided with grooved or protruding structures for connection with other plates to achieve the assembly of multi-layer water storage modules. Please refer to [link / reference]. Figure 5 , Figure 5 For the reason Figure 4 The assembled structure formed by the water storage modules shown demonstrates the overall effect of multiple modules being connected by grooves and protrusions, which facilitates the expansion of water storage capacity.

[0022] An impermeable layer 400 is installed below the water storage layer 300 to prevent water loss through seepage. The impermeable layer 400 may be made of HDPE membrane. The impermeable layer 400 is equipped with a permeation valve 410. When the water level sensor 320 detects that the water level in the water storage layer 300 exceeds a preset threshold, such as 0.8m, the permeation valve 410 opens, allowing the stored water in the water storage layer 300 to enter the perforated drain pipe 500 below.

[0023] In addition, the modular intelligent control sunken green space system provided in this embodiment also includes an overflow outlet 600, which extends vertically and is 50-100mm above the permeable pavement layer 100, for overflowing in case of excessive rainfall. A sewage interception basket 610 can be installed inside the overflow outlet 600 to physically intercept pollutants and impurities washed down during periods of high runoff. The system may also include a rainwater pipe 700 connected to a perforated drainage pipe 500 for further collection and discharge of rainwater.

[0024] In summary, the modular intelligent controllable sunken green space system provided in this embodiment includes a permeable pavement layer 100, a filtration and purification layer 200, a water storage layer 300, an impermeable layer 400, and a perforated drainage pipe 500. The filtration and purification layer 200 is located below the permeable pavement layer 100 and is composed of prefabricated filtration and purification modules 210. The filtration and purification module 210 includes, from top to bottom, a biochar-zeolite mixed layer, a nano-ceramsite layer, and a coarse sand layer, with each layer separated by geotextile. The water storage layer 300 is located below the filtration and purification layer 200 and is composed of prefabricated water storage pipes. The system is composed of modules 310, and the water storage layer 300 is equipped with a water level sensor 320 for real-time monitoring of the water level. The seepage-proof layer 400 is located below the water storage layer 300 and is equipped with a seepage valve 410. The perforated drainage pipe 500 is located below the seepage-proof layer 400. When the water level sensor 320 detects that the water level exceeds a preset threshold, the seepage valve 410 opens, and the stored water in the water storage layer 300 enters the perforated drainage pipe 500, thereby realizing real-time adjustment of the water storage and drainage strategy according to rainfall and avoiding water accumulation or resource waste.
