[0025] The present invention will be described in further detail below with reference to the accompanying drawings.

[0026] As shown in Figure 1 , Figure 2 , a kind of planting roof structure, including drainage plate 1, geotextile layer 2, planting layer 3, drain pipe 4 and air pipe 5.

[0027] As shown in Figure 1 , Figure 2 , drainage plate 1 is laid on roof, and drainage plate 1 includes bottom plate 11 and convex cup 12, convex cup 12 is vertically and uniformly distributed on bottom plate 11, and the lower end of convex cup 12 is provided with opening, and drainage groove 13 is formed between convex cup 12 and the upper surface of bottom plate 11, which is longitudinally and transversely staggered and interconnected.

[0028] As shown in Figure 1 , Figure 2 , geotextile layer 2 is laid on drainage plate 1, and planting layer 3 is arranged on geotextile layer 2 for planting plants.

[0029] As shown in Figure 1 , Figure 2 , drain pipe 4 and air pipe 5 are provided with multiple, and vertically arranged on drainage plate 1, drain pipe 4 and air pipe 5 all penetrate geotextile layer 2 and planting layer 3, the upper end of drain pipe 4 is flush with the upper surface of planting layer 3 or embedded in the inner part of the upper end of planting layer 3, and air pipe 5 extends above planting layer 3.

[0030] When it rains, the seepage water flow that penetrates below planting layer 3 will be discharged along the drainage groove 13 on the drainage plate 1, and the surface water flow on the planting layer 3 will be collected to the drain pipe 4 pipe opening position and discharged to the drainage plate 1, and then discharged along the drainage groove 13 on the drainage plate 1.

[0031] By setting the bottom drainage plate 1 and the drain pipe 4 connected with the drainage plate 1, the timely discharge of seepage water flow can be realized by using the drainage plate 1, and the surface water flow on the planting layer 3 can be timely drained by using the drain pipe 4, which prevents the accumulation of too much rainwater on the roof, guarantees the normal growth of plants and avoids the leakage phenomenon of the roof. At the same time, the whole structure can realize zero carbon emission construction, reduce the pollution to the environment, achieve the effect of energy saving and environmental protection, and be widely used in substation engineering.

[0032] As shown in Figure 2 , Figure 3 , drain pipe 4 includes bottom pipe 41 and top pipe 42, top pipe 42 is vertically and slidingly connected to bottom pipe 41, so that after the construction of drain pipe 4, top pipe 42 can be pulled to the uppermost end, and then the planting layer 3 is backfilled. When backfilling is completed, press down the top pipe 42 to move downward, so that the top pipe 42 is flush with the upper surface of the planting layer 3 or embedded in the inner part of the upper end of the planting layer 3. Therefore, when the planting layer 3 is backfilled, there is no need to lay out lines or set levels, so that the construction process is more convenient.

[0033] At the same time, the telescopic drain pipe 4 can adapt to the planting layer 3 of different thicknesses, improving practicality. At the same time, after the planting layer 3 sinks, the top pipe 42 can be pressed downward to ensure that the surface water flow of the planting layer 3 can be stably discharged into the drain pipe 4.

[0034] like Figure 2 、 Figure 3 As shown, a circle of pressure ring 43 is provided on the outer wall of the upper end of the top pipe 42. Therefore, when the top pipe 42 is pressed down, on the one hand, the top pipe 42 can be supported to prevent the top pipe 42 from retracting into the bottom pipe 41, thereby ensuring the stable discharge of surface water flow. On the other hand, when pressed into the planting layer 3, a step surface can be formed between the pipe mouth position of the top pipe 42 and the planting layer 3. Even if the soil in the planting layer 3 falls, it will fall on the pressure ring 43 and will not directly enter the drain pipe 4, thereby preventing the drain pipe 4 from being blocked.

[0035] like Figure 3 As shown, a filter screen 44 is provided at the upper end of the top pipe 42 to filter the surface water flow and prevent mud from clogging the drain pipe 4, thereby ensuring the stable operation of the drain pipe 4.

[0036] like Figure 3 、 Figure 4 As shown, the lower outer walls of the drain pipe 4 and the vent pipe 5 are both horizontally provided with a mounting plate 6 , and the lower end surface of the mounting plate 6 is provided with a plurality of sleeves 61 with lower ends opened, and the sleeves 61 are used to be sleeved on the convex cup 12 .

[0037] like Figure 3 、 Figure 4 As shown, a hook 62 is provided on the top wall of the sleeve 61 , and a blade 63 is provided at the lower end of the hook 62 . The blade 63 is used to pierce the upper end of the convex cup 12 and make the hook 62 hook tightly to the top wall of the convex cup 12 .

[0038] Therefore, when installing the drain pipe 4 and the vent pipe 5, the mounting plate 6 is laid flat on the drain board 1, and the sleeve 61 is sleeved on the corresponding convex cup 12, and then the mounting plate 6 is pressed to make the mounting plate 6 drive the sleeve 61 to move downward and make the sleeve 61 sleeved on the convex cup 12.

[0039] At the same time, as force is applied to the mounting plate 6, the hook 62 on the sleeve 61 moves downward synchronously. At this time, the blade 63 on the hook 62 pierces the convex cup 12, and the hook 62 passes through the convex cup 12 and hooks the top wall of the convex cup 12 to achieve clamping and fixing, thereby realizing convenient installation of the drainage pipe 4 and the ventilation pipe 5, making the construction process of the green roof more convenient, improving construction efficiency, and also ensuring the stability of the drainage pipe 4 and the ventilation pipe 5 during operation.

[0040] The specific embodiment is only an interpretation of the utility model, and is not a limitation of the utility model. Those skilled in the art can make modifications to the embodiment without creative contribution after reading the specification, but as long as the modifications are within the scope of the claims of the utility model, they are protected by the Patent Law.
