[0021] Figure 4 This is a schematic diagram of the structure of the water storage layer of this utility model. Detailed Implementation

[0022] Figure 1Figure 4 is a schematic diagram of the structure of this utility model. As shown in the figure, the vegetation tray for the roof system in this embodiment includes a tray body. The tray body contains, from top to bottom, layers of vegetation 1, substrate 2, filter 3, water storage 4, and drainage 5. The tray body is composed of several groups, arranged along a predetermined path, and the drainage layers 5 of these groups are interconnected. Through the modular splicing of the tray bodies, compared with existing technologies, this method can be used for green vegetation roof construction in complex situations and where material transportation is difficult, ensuring high efficiency in green vegetation roof construction, saving manpower, materials, and other resources, and reducing costs. In this solution, the tray bodies are connected horizontally and vertically to form a roof with a large coverage area. In practical applications, they can be arranged to form numbers, letters, or predetermined shapes for the coverage structure, which will not be elaborated further here.

[0023] In this embodiment, adjacent tray bodies are detachably connected. This allows for diverse and flexible design of the vegetation trays used in roofing systems, enabling quick installation, safe construction, and simple and convenient construction; they are also easy to transport, install, and disassemble. This utility model has a simple structure, is manufactured in a production workshop, and assembled on-site without additional fixing. It does not affect other construction procedures or completed construction projects, and can be quickly disassembled and replaced later, saving manpower and financial resources.

[0024] In this embodiment, the drainage layer 5 has an outwardly extending outer connecting portion 52, which has an outer flow channel connecting the external environment and the drainage layer 5; the drainage layer 5 also has an inwardly recessed inner connecting portion 51, which has an inner flow channel connecting the external environment and the drainage layer 5; after adjacent tray bodies are connected, the outer connecting portion 52 is embedded into the inner connecting portion 51, and the inner flow channel and the outer flow channel are correspondingly connected, thus connecting the drainage layers 5 of adjacent tray bodies. The structure is simple and reliable. The inner connecting portion 51 and the outer connecting portion 52 serve as positioning and assembly components, improving assembly efficiency and connection reliability. They possess anti-slip and anti-pull-out capabilities, exhibiting good overall consistency. Furthermore, they connect adjacent drainage layers 5, enabling integrated drainage of the entire roof covering system and improving the quality of the finished product.

[0025] In this embodiment, the outer connecting part 52 and the inner connecting part 51 form a set of water-passing bridges communicating with the drainage layer 5, and each tray body has at least two sets of water-passing bridges. This allows the overall roof system to have a multi-branched water-passing area connected horizontally and vertically, reducing the concentration of water areas, while improving the uniformity and consistency of water source distribution, enhancing the survival rate of green vegetation, and facilitating maintenance.

[0026] In this embodiment, the outer connecting part 52 and the inner connecting part 51 of a set of water-passing bridges are opposite each other. The water-passing efficiency is higher. This solution sets the tray body to be a rectangular cube, and the two sets of opposite water-passing bridges are distributed on the circumferential surface of the rectangular cube, so that the connecting line of the two sets of water-passing bridges is perpendicular. The structure is simple and reliable, and the installation and disassembly are more convenient, improving construction efficiency; the structural connection stability is also better.

[0027] In this embodiment, after adjacent tray bodies are connected, the outer connecting part 52 and the inner connecting part 51 are connected by mortise and tenon joints. The mortise and tenon structure design, resembling a jigsaw puzzle, allows the tray bodies to be assembled like a jigsaw puzzle. Figure 1 The components are connected in this way to reinforce the stability of the drainage layer 5 and prevent it from being affected by lateral forces. Specifically, the outer connecting part 52 has a tenon structure with a smaller inner end and a larger outer end. The bottom surface of the outer connecting part 52 is coplanar with the bottom surface of the tray body. The outer flow channel is T-shaped and recessed in the outer connecting part 52 from top to bottom. The bottom of the T-shape connects inward to the drainage layer 5, and the top of the T-shape passes through both sides of the outer connecting part 52 to connect with the external environment. The inner connecting part 51 and the outer connecting part 52 have the same shape and are formed by the concave bottom of the tray body. A through hole is opened in the inner connecting part 51 at the through position corresponding to the top of the T-shape of the outer connecting part, so that after the outer connecting part 52 and the inner connecting part 51 are connected by mortise and tenon, the outer connecting part 52 and the inner connecting part 51 form a water bridge that connects with the drainage layer 5.

[0028] In this embodiment, the filter layer 3 has a plurality of water-filtering holes 31 running from top to bottom. This serves two purposes: ensuring structural support and filtering water, preventing debris from falling, protecting the water storage layer 4 and drainage layer 5, enhancing protective functions, and improving water flow capacity. It effectively controls and maintains the roof substrate layer 2, preventing particles and nutrients in the substrate from being lost with rainwater, and blocking impurities such as leaves and dust from entering the drainage system, thereby keeping the drainage system unobstructed.

[0029] In this embodiment, a siphon pipe 41 is provided inside the water storage layer 4. The inlet of the siphon pipe 41 is located inside the water storage layer 4 and at a set distance from the bottom of the water storage layer 4. The outlet of the siphon pipe 41 is connected to the drainage layer 5. A baffle 42 is provided inside the siphon pipe 41. When the water level rises to the set distance, a water-retaining layer is formed. When the water level continues to rise, it is further blocked by the built-in baffle 42, and the water-retaining layer thickens. Within a preset controllable range, when the water level exceeds the baffle 42, the siphon pipe 41 will siphon the water in the water storage layer 4. The structure of the water storage layer 4 has a certain water storage capacity, which can collect rainwater and reduce irrigation. When the water volume is too large, the water storage layer 4 can be discharged in time to prevent water accumulation and improve the survival rate of green vegetation.

[0030] In this embodiment, the tray body is manufactured as a single piece. The bottom of the integrally manufactured tray body forms a water storage layer 4 and a drainage layer 5 connected by a siphon pipe 41. The integrally manufactured tray body also includes a filter layer 3 located on top of the water storage layer 4. The tray body is made of polypropylene copolymer to ensure high temperature resistance, acid and alkali resistance, and durability. Filter holes 31 are reserved on the filter layer.

[0031] In this embodiment, the vegetation layer 1 and the substrate layer 2 are laid on top of the filter layer 3 from top to bottom. The substrate layer 2 can use a lightweight growth medium, selected based on the growth characteristics of the planted plants, such as rice husks, vermiculite, expanded clay, peat moss, synthetic foam or rock wool, or polyacrylonitrile fiber flocculent material. This substrate is thin, has a light load, and offers better durability and water retention. The special substrate layer 2 requires no management, allowing the green plants to grow healthily under natural climatic conditions. The plant layer can be planted with shallow-rooted plants such as sedum, grasses, and small shrubs, improving survival rates and facilitating maintenance.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
