Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0036] Please refer to Figures 1-6 , this embodiment provides a technical solution:

[0037] An upper cover type greening fill planting structure for reducing load, including a housing 1. Inside the housing 1, a drainage board 4, a filling assembly and a soil wrapping cloth 2 are successively arranged from bottom to top. A soil layer 3 is arranged in the middle of the soil wrapping cloth 2. The width of the outer wall of the soil wrapping cloth 2 is adapted to the width of the inner wall of the housing 1. The bottom of the soil wrapping cloth 2 is closely attached to the top of the upper extruded polystyrene board 5, and the side walls of the soil wrapping cloth 2 are respectively closely attached to the inner wall of the top of the housing 1.

[0038] In the present invention, the soil wrapping cloth 2 is a water-permeable geosynthetic material made of synthetic fibers by needling or weaving. The soil wrapping cloth 2 is arranged to protect the upper soil layer 3, reduce the influence of the loss of planting soil, and the soil wrapping cloth 2 has water transmission property, which helps with bottom drainage cooperation.

[0039] Furthermore, the bottom of the soil layer 3 is closely attached to the upper surface of the soil wrapping cloth 2.

[0040] In the present invention, the soil layer 3 is made of lightweight planting soil and is filled above the soil wrapping cloth 2 for easy planting use.

[0041] It should be noted that a plurality of convex blocks 40 are arranged on the upper surface of the drainage board 4. A plurality of water guide grooves 41 are also opened on the upper surface of the drainage board 4. Both ends of the water guide grooves 41 are provided with conduits 42. A drain pipe 10 corresponding to the conduit 42 is provided at a position near the bottom on the front end face of the housing 1. The width of the outer wall of the drainage board 4 is adapted to the width of the inner wall of the housing 1. The convex blocks 40 are distributed in a matrix, and the convex blocks 40 and the drainage board 4 are of an integrally formed structure.

[0042] In the present invention, with the cooperation of a plurality of convex blocks 40, it helps to support the upper extruded polystyrene board 5. A gap is left between the extruded polystyrene board 5 and the drainage board 4, which helps with drainage cooperation.

[0043] Furthermore, the water guide grooves 41 are located in the gaps between the convex blocks 40, and the water guide grooves 41 are equally spaced. The interiors of the conduits 42 are all interconnected with the interiors of the water guide grooves 41. The front ends of the conduits 42 extend to the front end of the drainage board 4, and water outlets 420 are opened at the front ends of the conduits 42.

[0044] In the present utility model, with the cooperation of a plurality of water guide grooves 41, it is helpful to guide and discharge the aqueous solution on the drainage plate 4, and with the cooperation of the conduit 42, the water is stably guided and easily discharged from the front end.

[0045] Specifically, the drain pipe 10 is adhesively fixed to the outer shell 1, and the inside of the drain pipe 10 is communicated with the water outlet 420.

[0046] In the present utility model, the arrangement of the drain pipe 10 helps to correspond to the water outlet 420 on the conduit 42, and then guides the aqueous solution in the water guide groove 41 to be quickly discharged and collected.

[0047] It is worth adding that the filling component is composed of a plurality of extruded plastic plates 5. A number of trapezoidal grooves 50 are formed at one end of the extruded plastic plate 5, and a number of trapezoidal blocks 51 are provided at the other end of the extruded plastic plate 5.

[0048] Secondly, the extruded plastic plates 5 are arranged at equal intervals, and the adjacent two extruded plastic plates 5 on the horizontal plane are inserted and matched through the trapezoidal blocks 51 and the trapezoidal grooves 50. The length of the outer wall side of the extruded plastic plate 5 is adapted to the width of the inner wall of the outer shell 1.

[0049] In the present utility model, the extruded plastic plate 5 is made of a polystyrene heat insulation cushion plate, which has a light self-weight, high compressibility, and good structural stability. A plurality of extruded plastic plates 5 are combined into a filling component together. The width of the outer wall of the trapezoidal block 51 is adapted to the width of the inner wall of the trapezoidal groove 50. The trapezoidal block 51 on one of the extruded plastic plates 5 is inserted and matched with the trapezoidal groove 50 on the adjacent extruded plastic plate 5 to realize the stable assembly and cooperation between the adjacent extruded plastic plates 5.

[0050] When the upper cover type greening fill planting structure for reducing load of this embodiment is in use, the user first lays the drainage system, spreads the drainage plate 4 with bumps 40 and water guide grooves 41 at the bottom of the outer shell 1, then aligns the drain pipe 10 on the outer shell 1 with the water outlet 420 at the end of the conduit 42, and then lays the filling component to make full use of the space at the bottom of the outer shell 1, which can reduce the amount of backfill soil and reduce the self-weight of the top plate. The adjacent two extruded plastic plates 5 are tightly inserted and matched, and the trapezoidal block 51 on one of the extruded plastic plates 5 is inserted and matched with the trapezoidal groove 50 on the other extruded plastic plate 5 to increase the stability of the assembly. Then, the soil wrapping cloth 2 is placed above the filling component, the bottom of the soil wrapping cloth 2 is closely attached to the upper extruded plastic plate 5, and the side walls around the soil wrapping cloth 2 are all closely attached to the inner wall of the outer shell 1. Finally, the soil layer 3 of the backfill soil to be filled is filled into the soil wrapping cloth 2.

[0051] When planting is required, corresponding vegetation is planted in the soil layer 3. When watering, the excess water is filtered and intercepted by the soil wrapping cloth 2, reducing the impact of backfill soil loss. Moreover, the excess water enters the drainage board 4 and is centrally discharged through the drain pipe 10 under the guiding cooperation of the conduit 42. With the cooperation of multiple extruded plastic boards 5, the amount of backfill soil is reduced, the self-weight of the top plate is lightened, thereby realizing the reduction of the top plate load and the top pressure, and the overall combined installation is convenient and fast.
