[0021] refer to Figure 1 and Figure 2As shown, a rainwater siphon collection and drainage system for a planting roof includes a planting layer 1, a rainwater well 2, an inspection well 3, a planting top plate 4, a special-shaped siphon layer 5, a siphon guide pipe 6, a geotextile filter layer 7, a first drainage pipe 8, a second drainage pipe 9, a breather pipe 10, a plain soil ramming layer 11, a plain concrete layer 12, a reinforced concrete layer 13, a concrete protection port 14, a fine stone concrete bottom layer 15, a brick-built load-bearing ring 16, a fine stone concrete upper port 17, a well cover 18, a leveling layer 19, a waterproof membrane layer 20, a root-penetration-resistant waterproof membrane layer 21 and a four-way 22.

[0022] The planting layer 1 is a soil layer for planting vegetation, and most of the components of the system are located in the planting layer 1. A rainwater well 2 is provided in the planting layer 1, and the upper wellhead of the rainwater well 2 is flush with the upper surface of the planting layer 1. The rainwater well 2 is used to connect to the municipal rainwater pipeline to achieve drainage. An inspection well 3 is provided in the planting layer 1, and the upper wellhead of the inspection well 3 is flush with the upper surface of the planting layer 1. The inspection well 3 is close to the building and is used for temporary storage and drainage of rainwater.

[0023] The bottom of the inspection well 3 is inserted into the concrete protection opening 14. The concrete protection opening 14 is a ring structure made of C20 concrete, which can ensure the stability of the bottom of the inspection well 3. A reinforced concrete layer 13 is provided below the concrete protection opening 14. The reinforced concrete layer 13 is made of C30 concrete with double-sided bidirectional steel bars, which is used to support the protection opening and the inspection well 3. A plain concrete layer 12 is provided below the reinforced concrete layer 13. A plain soil ramming layer 11 is provided below the plain concrete layer 12. The plain concrete layer 12 is made of C20 concrete. The plain soil ramming layer 11 is a soil body with a density of 95%. The two together support the upper part.

[0024] The top of the inspection well 3 is inserted into the brick-built load-bearing ring 16, and the brick-built load-bearing ring 16 is used to limit the top of the inspection well 3. A fine stone concrete bottom layer 15 is provided below the brick-built load-bearing ring 16. The fine stone concrete bottom layer 15 is cast with C25 concrete and is used to provide a foundation for bricklaying and to support the load-bearing ring later. A fine stone concrete upper opening 17 is provided above the brick-built load-bearing ring 16. The fine stone concrete upper opening 17 is cast with C25 concrete and is used to provide a foundation for the placement of a manhole cover 18. A manhole cover 18 is provided on the fine stone concrete upper opening 17 to shield the inspection well 3, and the manhole cover 18 is used to shield and protect the wellhead.

[0025] A planting top plate 4 is provided in the planting layer 1. The planting top plate 4 is a cast-in-place reinforced concrete structure located inside the planting soil, that is, the top structure of the building, and the planting operation is carried out based on this.

[0026] A leveling layer 19 is provided on the planting top plate 4. The leveling layer 19 is made of 5 cm thick fine stone concrete material to achieve leveling of the working surface. A waterproof roll layer 20 is provided above the leveling layer 19. The waterproof roll layer 20 is made of 1.5 mm thick SBS material to ensure the waterproof effect of the top layer. A root puncture resistant waterproof roll layer 21 is provided above the waterproof roll layer 20. The root puncture resistant waterproof roll layer 21 is made of self-adhesive material, which is convenient for construction and prevents the penetration of vegetation roots.

[0027] A special-shaped sheet siphon layer 5 and a siphon guide tube 6 are arranged side by side above the root-penetration-resistant waterproof membrane layer 21. The special-shaped sheet siphon layer 5 is fully spread on the top plate and fixed by splicing or bonding. The special-shaped sheet siphon layer 5 is made of PVC polymer material and is used for distributed regional rainwater collection and small-scale water delivery and drainage. At the same time, the special-shaped sheet siphon layer 5 is an anti-collapse structure, which satisfies the flow of water on the anti-collapse structure, reduces the pressure of the drainage layer, and ensures that the waterproof layer will not be damaged during the backfilling, playing a role of soft protection. The polymer special-shaped sheet adopts a structural anti-collapse design with the function of preventing geotextile collapse, and sufficient drainage space can be guaranteed without bonding the geotextile to the drainage board.

[0028] The siphon guide pipe 6 is made of PE material. The siphon guide pipe (permeate water collection pipe) and the pipe are connected in series to form a network, which is used to connect the distributed regional trunk water supply and drainage. The water seeping / overflowing from the geotextile or special-shaped sheet is gathered in the guide pipe, and then the excess water is discharged. The siphon guide pipes 6 are connected in series through the four-way 22. The four-way and the plug are used to connect the siphon guide pipes of each distributed area in series. The siphon guide pipe and the pipe are connected by a clamping method.

[0029] A geotextile filter layer 7 is provided on the special-shaped sheet siphon layer 5 and the siphon guide tube 6 to block the planting layer 1. The geotextile filter layer 7 is made of 200g / ㎡ synthetic fiber material and is used for filtering seepage mud and sand to prevent mud and sand from entering the special-shaped sheet and the siphon tube.

[0030] The siphon guide pipe 6 is connected to the inspection well 3 in the planting layer 1 through the second drainage pipe 9, and the inspection well 3 is connected to the rainwater well 2 in the planting layer 1 through the first drainage pipe 8. The overflowing water gathers in the inspection well and is then discharged into the municipal pipe network through the inspection well to avoid excessive water accumulation in the planting layer 1.

[0031] The shaped sheet siphon layer 5 or the siphon guide pipe 6 is connected to the air permeable pipe 10 extending out of the planting layer 1. The air permeable pipe 10 is made of PP material and is used for air flow exchange of the water supply trunk line. A dust cover needs to be installed on the top of the air permeable pipe. Preferably, the air permeable pipe 10 is arranged at the series joint of the siphon guide pipe 6. Special glue / adhesive is used for assembling single PVC polymer shaped sheets into sheets and splicing PE material siphon guide pipes and air permeable pipes into a net.

[0032] The above basic examples and further optional examples of the utility model can be freely combined to form multiple embodiments, which are all embodiments that can be adopted and claimed for protection by the utility model. In the scheme of the utility model, each optional example can be arbitrarily combined with any other basic examples and optional examples.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
