[0065] Furthermore, the planted roof system further includes a vegetation layer planted on the planting soil layer 90.

[0066] The construction process of the planted roof system of the present invention will be described below.

[0067] Step 1: Detailed design. According to the structure form and characteristics of the sloping roof, the anti - slip planted roof system is deeply designed to determine the specifications and embedded spacing of the embedded parts 11, the layout spacing of the fixing plates 12, the layout direction and spacing of the baffle plates 71.

[0068] Step 2: Reservation and embedding. When constructing the sloping roof structural slab 10, use a total station to measure and position the embedded parts 11 for embedding. After the sloping roof structural slab 10 is poured and cured to reach the required strength, the next step of construction can be carried out.

[0069] Step 3: Subgrade construction. After the casting of the sloping roof structural slab 10 is completed and cured to reach the required strength, the sloping roof structural slab 10 is polished and repaired to be flat, and then the waterproof coiled material is constructed. When constructing the waterproof coiled material, since the embedded parts 11 reserved on the sloping roof structural slab 10 will damage the waterproof coiled material, waterproof strengthening treatment needs to be carried out at the positions of the embedded parts 11. Polyurethane coating can be used. After the construction of the waterproof coiled material is completed, the upper extruded polystyrene insulation board is laid. If there is no insulation requirement for the space below the sloping roof structural slab 10, the extruded polystyrene insulation board can be not laid and directly proceed to the next layer of construction; after the laying of the extruded polystyrene insulation board is completed, the second protective layer 40 is constructed. The second protective layer 40 needs to be plastered and polished. The thickness of the rigid protective layer is preferably 40 mm and is internally provided with a single-layer bidirectional steel mesh. The specific thickness and the specifications of the steel mesh can be determined according to the actual situation. After the second protective layer 40 reaches the required strength, the SBS root-resistant waterproof coiled material is laid on the second protective layer 40. After the construction of the SBS root-resistant waterproof coiled material is completed, the first protective layer 60 is constructed. After the first protective layer 60 reaches the required strength, the next step of construction is carried out;

[0070] Step 4: Physical anti-slip layer construction. After the first protective layer 60 reaches the required strength, the fixing plate 12 is firmly welded to the embedded parts 11 reserved on the sloping roof structural slab 10 by welding. Subsequently, the retaining plate is fixed on the fixing plate 12. After the installation of the baffle 71 is completed, the water storage plate 80 is laid. After the laying of the water storage plate 80 is completed, a layer of non-woven fabric filter layer 81 is laid above it, and then the corrugated plate 72 is installed.

[0071] Step 5: Backfill the planting soil and plant vegetation simultaneously.

[0072] The present invention also provides a construction method of a planting roof system as described above, including the following steps:

[0073] When constructing the roof structural slab 10, a plurality of rows of the embedded parts 11 are embedded on the roof structural slab 10, so that a part of the embedded parts 11 protrudes outside the roof structural slab 10;

[0074] The first waterproof layer 50 is laid on the roof structural slab 10, so that the top ends of the embedded parts 11 are exposed outside the first waterproof layer 50;

[0075] The grid structure 70 is laid on the first waterproof layer 50, so that the grid structure 70 is fixedly connected to the top ends of the embedded parts 11;

[0076] The planting soil is filled and covered on the grid structure 70 to form a planting soil layer 90.

[0077] In a specific embodiment, when constructing the first waterproof layer 50, the second waterproof layer 20 is laid on the roof structural slab 10, the thermal insulation layer 30 is laid on the second waterproof layer 20, the second protective layer 40 is laid on the thermal insulation layer 30, and the first waterproof layer 50 is laid on the second protective layer 40. The embedded part 11 penetrates through the second waterproof layer 20, the thermal insulation layer 30, and the second protective layer 40.

[0078] Furthermore, when constructing the grid structure 70, the first protective layer 60 is laid on the first waterproof layer 50, the fixing plate 12 is fixed to the top of each row of the embedded parts 11 along the arrangement direction of each row of the embedded parts 11, several baffles 71 are installed on several of the fixing plates 12, the water storage plate 80 is laid on the first protective layer 60, so that the water storage plate 80 is located between two adjacent baffles 71 and abuts against the corresponding baffle 71, the non-woven fabric filter layer 81 is laid on the water storage plate 80, and the corrugated plate 72 is installed between two adjacent baffles 71 and is located above the non-woven fabric filter layer 81.

[0079] By adopting the above technical solutions, the present invention has the following beneficial effects:

[0080] In the present invention, the downward sliding force of the soil is gradually transmitted to the roof structural slab 10 through the embedded part 11, the fixing plate 12, the baffle 71, and the corrugated plate 72, having a good anti-slip function. Through the arrangement of the waterproof coiled material, the SBS root-resistant puncture waterproof coiled material, the water storage plate 80, and the non-woven fabric filter layer 81, in addition to meeting the plant growth requirements, it also has good waterproof and drainage functions.
