[0002] In recent years, with the acceleration of urbanization, many "urban diseases" have become increasingly prominent. Large-scale greenhouse gas emissions have led to frequent flooding and rapid shifts between drought and flood. The construction of sponge cities follows principles such as ecological priority, combining natural methods with artificial measures to maximize rainwater retention in urban areas while ensuring urban drainage and flood control safety. Green roofs, in particular, have emerged based on the design concept of sponge cities.

[0003] Green roofs, also known as planted roofs or rooftop greening, are roof modules with functions such as infiltration, storage, pollution interception and purification, photovoltaic power generation, and intelligent control terminals. Conventional green roofs are typically installed on the existing roof of a building, forming a single, integrated structure. Their construction process is relatively complex and requires a high level of quality from the existing roof. Furthermore, the large size and weight of the integrated roof structure make transportation difficult. In some traditional buildings, the original roof has weakened load-bearing capacity and waterproofing capabilities due to aging, making it difficult to achieve safe and satisfactory results using existing green roofs.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Example 1: This embodiment provides a green and environmentally friendly prefabricated roof structure, specifically as follows: Figures 1-6 As shown, it includes: A modular pool is used for cultivating green plants or installing photovoltaic modules. The modular pool comprises multiple interconnected modular pool units 10. Each modular pool unit 10 includes a base 100 (size: 2m × 2m × 2m), made of recycled polypropylene and glass fiber composite material (wall thickness 8mm, compressive strength ≥15MPa). In this embodiment, the specific ratio of polypropylene to glass fiber is 7:3. The base 100 has a splicing structure for combining the bases. The base 100 has connecting holes 106 for connecting the assembled bases. Each base 100 has a drainage hole 105 at its bottom. Water-storing and purifying filler is placed in the combined pool to collect and purify rainwater.

[0025] During rooftop installation, multiple modular pool units 10 are first hoisted onto the roof surface. Then, a certain number of modular pool units 10 are assembled into a modular pool using a splicing structure. The number of modular pool units 10 is adjusted according to the roof area. Based on customer needs, photovoltaic modules are installed on some of the modular pool units 10. The photovoltaic modules generate electricity to supply the customer's daily needs (the number of photovoltaic modules is determined by ensuring sufficient power generation without excessive redundancy, reducing the customer's installation costs). Greenery is planted on the remaining modular pool units 10, which helps purify rainwater and reduces roof heat.

[0026] During rainfall, the combined pool collects rainwater, and the water-purifying filler can purify the rainwater. At the same time, the collected rainwater can ensure the normal growth of green plants. Excess water is connected to the customer's home through the drain hole 105 and controlled by a valve. It can be used for purposes such as flushing toilets and watering flowers.

[0027] Example 2: This embodiment further extends the above embodiment, specifically as follows: Figures 1-4 As shown, the splicing structure includes a raised trapezoidal groove 101 and a recessed trapezoidal groove 102. The raised trapezoidal groove 101 and the recessed trapezoidal groove 102 are disposed on the side of the base 100. The raised trapezoidal groove 101 and the recessed trapezoidal groove 102 disposed on different bases 100 form a fit. At the cross-section of the trapezoidal groove, the upper base is 5cm long, the lower base is 8cm long, and the inclination angle is 30°. The number of raised trapezoidal grooves 101 and recessed trapezoidal grooves 102 are A and B, respectively, 0≤A≤4, 0≤B≤4, 1≤A+B≤4, where A and B are both natural numbers.

[0028] exist Figure 3 The number of A+B is 2 or 3. Figure 3 The number of A+B units is 2, 3, or 4, and the specific installation method is mainly customized by the customer. During assembly, the raised trapezoidal groove 101 is slidably inserted into the recessed trapezoidal groove 102 to connect the combined pool unit 10. After connection, the two connecting holes 106 are automatically connected, and a sealing gasket is provided at the connecting hole 106 to prevent rainwater leakage.

[0029] Both the raised trapezoidal groove 101 and the recessed trapezoidal groove 102 are provided with mounting grooves 109, and permanent magnets 110 are installed on the mounting grooves 109. The permanent magnets 110 on the raised trapezoidal groove 101 will attract each other with the permanent magnets 110 on the recessed trapezoidal groove 102.

[0030] During assembly, the relative positions of the raised trapezoidal groove 101 and the recessed trapezoidal groove 102 are adjusted by the mutual attraction of the two permanent magnets 110, which helps the raised trapezoidal groove 101 to be inserted into the recessed trapezoidal groove 102, reducing alignment work. After assembly, the two permanent magnets 110 are in complete contact, the attraction force is increased, and rainwater will not leak at the connecting hole 106.

[0031] The combined pool unit 10 also includes reinforcing ribs 104 and casters 103. The base 100 is provided with reinforcing ribs 104 and casters 103 at its bottom. The reinforcing ribs 104 are used to improve the structural strength of the base 100 (stiffness increased by 40%). The casters 103 are heavy-duty polyurethane casters (single wheel load ≥200kg) and are equipped with hydraulic self-locking devices. A shock-absorbing spring layer (thickness 50mm) is added to reduce the impact of vibration in windy and rainy weather.

[0032] Both the raised trapezoidal groove 101 and the recessed trapezoidal groove 102 are provided with first pre-embedded holes 107, which are used for the pre-embedded laying of cables for photovoltaic modules.
