[0027] like Figures 1-4As shown, this utility model proposes a landscape cover structure for a secondary sedimentation tank sludge trough, including a cover body 1 and receiving grooves 2 and matching protrusions 3 respectively disposed at both ends of the cover body 1. The receiving grooves 2 and the matching protrusions 3 are fitted together. A cavity is provided at the top of the cover body 1, and a reinforcing layer 11, a separating layer 10, a water storage layer 9 and a planting layer are arranged sequentially from bottom to top in the cavity.

[0028] By creating a cavity in the main body 1 of the cover plate and arranging different functional layers inside the cavity, green plants can grow in the upper space of the sludge tank without affecting the flow of sludge.

[0029] Planting water lilies, which have well-developed root systems and are suitable for growing in moist environments, as surface vegetation in the planting layer can effectively remove nitrogen and phosphorus from the water, and they also have a good ornamental appearance.

[0030] The cover plate body 1 adopts a modular assembly form and is laid on top of the sludge tank. Through the connection between the receiving groove 2 and the matching protrusion 3 between adjacent cover plate bodies 1, the connection stability is ensured while enabling the rapid installation of the cover plate body 1.

[0031] The reinforcing layer 11 supports the partition layer 10, the water storage layer 9, and the planting layer, while also strengthening the bottom of the cover body 1 to prevent it from breaking. The partition layer 10 is used for sealing to prevent excess water from leaking into the upper water storage layer 9 and damaging the structure of the cover body 1. The water storage layer 9 is used to store water. The planting layer contains a substrate, through which plants are grown.

[0032] like Figures 1-3 As shown, this is to achieve planting of plants on the main body 1 of the cover plate. The planting layer includes a support plate 8, a water storage and drainage plate 6 arranged on the support plate 8, and planting cylinders 5 inserted into the water storage and drainage plate 6. The bottom of the water storage and drainage plate 6 is connected to a cylindrical connecting cylinder 7, and the bottom end of the connecting cylinder 7 is provided with an opening. The connecting cylinders 7 are arranged in an array on the water storage and drainage plate 6, and the planting cylinders 5 are inserted into the connecting cylinders 7. Six sets of connecting cylinders 7 are arranged on the water storage and drainage plate 6. The connecting cylinders 7 pass directly through the support plate 8, and the support plate 8 supports the water storage and drainage plate 6. The planting cylinders 5 are directly inserted into the top of the connecting cylinders 7. By planting plants in the planting cylinders 5, the arrangement of the connecting cylinders 7 maintains the spacing between the planted plants. The way the planting cylinders 5 are inserted into the top of the connecting cylinders 7 improves the installation efficiency of the planting cylinders 5.

[0033] like Figure 3 As shown, to improve the installation efficiency of the planting cylinder 5, an annular groove is provided at the top of the connecting cylinder 7, and the bottom end of the planting cylinder 5 is inserted into the annular groove. Both the connecting cylinder 7 and the planting cylinder 5 are filled with substrate. The connecting cylinder 7 has an annular groove at its top; the planting cylinder 5 is directly inserted into the top of the connecting cylinder 7, thus completing the installation of the planting cylinder 5. Then, substrate is poured into the planting cylinder 5 for planting the plants, and water is added.

[0034] like Figure 2 and Figure 4 As shown, to ensure the stable installation of the drainage board 6 and provide sufficient space for plant root growth, the support plate 8 includes a central grid structure and connecting plates fixed at both ends of the grid structure. The support plate 8 has evenly spaced openings for the connecting cylinder 7 to pass through, located within the internal cavity of the grid structure. Extending the connecting cylinder 7 increases its length, providing sufficient space for plant root growth and accommodating adequate substrate and water. Furthermore, the bottom of the extended connecting cylinder 7 is located within the cavity below the support plate 8, providing sufficient water for the plants. The way the connecting cylinder 7 is inserted into the support plate 8 ensures the installation stability of the drainage board 6; the internal structure of the support plate 8 prevents it from bending.

[0035] like Figure 2 As shown. A supporting step is provided in the cavity at the top of the cover plate body 1. The planting layer overlaps on the supporting step, and the water storage layer 9 is arranged in the cavity space below the supporting step. The supporting plate 8 is directly installed on the supporting step to shield the cavity space, which can reduce water evaporation in the cavity space and provide water for stable plant growth on the cover plate body 1; moreover, the supporting plate 8, as a layered structure, serves as the supporting structure at the bottom of the planting layer by setting the supporting step.

[0036] like Figure 2 As shown, to ensure the overall structural strength of the cover plate body 1, a reinforcing layer 11 is arranged at the bottom of the cavity in the cover plate body 1. The reinforcing layer 11 is a grid plate structure, and a pad is provided on the top of the reinforcing layer 11. The sidewall of the pad is attached to the inner sidewall of the cavity, and sealant is applied at the joint. The cavity at the top of the cover plate body 1 affects the overall structural strength of the cover plate body 1. Based on the dimensions of the bottom of the cavity, the reinforcing layer 11 is installed. The outer sidewall of the reinforcing layer 11 is attached to the inner sidewall of the cavity. The reinforcing layer 11 serves as a reinforcing structure inside the cover plate body 1, improving the overall structural strength of the cover plate body 1. The sealant prevents water from seeping in from the top through the joint.

[0037] like Figure 2 As shown, to prevent water leakage from above from corroding the reinforcing layer 11, the partition layer 10 includes a central metal plate and rubber sleeves covering the top and sides of the metal plate. The rubber sleeves fit snugly against the cavity, and are under pressure when the partition layer 10 is fixed. By using the metal plate as a frame, the partition layer 10 is pressed into the cavity during installation, and the edges are sealed using rubber sleeves or rubber strips to prevent moisture from above from entering the reinforcing layer 11.

[0038] like Figure 2 As shown, to slow down the evaporation of internal moisture, the water storage layer 9 is a plate-shaped foam, which is hydrophilic EVA foam. Existing hydrophilic EVA foam has undergone special treatment and has a certain water absorption and water storage capacity. Utilizing its strong corrosion resistance, it is used as a water-retaining buffer material for plant cultivation.

[0039] like Figure 2 As shown in the diagram, the bottom end of the connecting cylinder 7 is located inside the water storage layer 9, and a gap is provided between the support plate 8 and the water storage layer 9. Water permeable holes are evenly distributed on the side wall of the connecting cylinder 7. After the plant is planted, the plant roots are located at the bottom of the connecting cylinder 7. By pressing the bottom end of the connecting cylinder 7 against the inside of the water storage layer 9, the connecting cylinder 7 can replenish water internally through the water permeable holes, providing sufficient moisture for the plant.

[0040] like Figure 1 As shown, to improve the laying efficiency of the cover plate body 1, the adapting protrusion 3 is T-shaped, the receiving groove 2 is U-shaped, and a locking protrusion is provided on the inner side wall. By continuously laying the cover plate bodies 1, the connection between the two cover plate bodies 1 is achieved by locking the adapting protrusion 3 of the next cover plate body 1 into the receiving groove 2 of the previous cover plate body 1.
