DETAILED DESCRIPTION
[0023] The present invention will be further described below in conjunction with specific embodiments and drawings.
[0024] refer to Figure 1 As shown, a rainwater siphon collection and drainage structure for a planting roof includes a planting top plate 1, a leveling layer 2, a waterproof membrane layer 3, a root-penetration-resistant waterproof membrane layer 4, a special-shaped siphon layer 5, a siphon guide pipe 6, a geotextile filter layer 7, a planting layer 8, a breathable tube 9, a dust cover 10, a sheet adhesive tape 11, an angle adhesive tape 12 and a height difference slope 13.
[0025] The planting top plate 1 is a cast-in-place reinforced concrete structure located inside the planting soil, that is, the top structure of the building, on which the planting operation is carried out. A leveling layer 2 is provided on the planting top plate 1. The leveling layer 2 is made of 5 cm thick fine stone concrete material to achieve the leveling of the working surface. A waterproof roll layer 3 is provided above the leveling layer 2. The waterproof roll layer 3 is made of 1.5 mm thick SBS material to ensure the waterproof effect of the top layer. A root-penetration-resistant waterproof roll layer 4 is provided above the waterproof roll layer 3. The root-penetration-resistant waterproof roll layer 4 is made of self-adhesive material, which is convenient for construction and prevents the penetration of vegetation roots.
[0026] 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 4. 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 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.
[0027] 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 a four-way connection. The four-way connection 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.
[0028] A geotextile filter layer 7 is provided on the siphon layer 5 and the siphon guide pipe 6 to block the planting layer 8. The geotextile filter layer 7 is made of 200g / ㎡ synthetic fiber material and is used to filter the seepage mud and sand to prevent the mud and sand from entering the siphon pipe. The planting layer 8 is a soil layer for planting vegetation.
[0029] refer to Figure 2As shown, the geotextile filter layer 7 is fully spread on the special-shaped siphon layer 5 and the siphon guide pipe 6, and the geotextile filter layers 7 are connected by overlapping stitching or overlapping bonding, with an overlapping width of 30-100mm.
[0030] refer to Figure 3 As shown, the ends of the special-shaped sheet siphon layers 5 are arranged relative to each other, a small gap is left at the ends between two adjacent special-shaped sheet siphon layers 5 to form a flat seam splicing structure, and the ends between the two adjacent special-shaped sheet siphon layers 5 are connected with a sheet-like adhesive tape 11 located below, the sheet-like adhesive tape 11 is located above the root penetration resistant waterproof roll material layer 4, and has a width of 50-100mm, and is used to realize the connection between the two special-shaped sheets.
[0031] refer to Figure 1 As shown, the special-shaped siphon layer 5 or the siphon guide tube 6 is connected to the air permeable tube 9 extending out of the planting layer 8. The air permeable tube 9 is made of PP material and is used for air flow exchange of the water supply trunk line. A dust cover 10 needs to be installed on the top of the air permeable tube. Preferably, the air permeable tube 9 is arranged at the series joint of the siphon guide tube 6.
[0032] The bottom of the air pipe 9 extends to the reserved space between the special-shaped sheet siphon layers 5, that is, the special-shaped sheet siphon layer 5 needs to be interrupted at the position where the air pipe 9 is arranged. Or the bottom of the air pipe 9 extends into the siphon guide pipe 6. The geotextile filter layer 7 is wrapped around the bottom of the air pipe 9 and fixed by bonding.
[0033] refer to Figure 4 and Figure 5 As shown, in the case where there is a height difference step in the planting top plate 1, two methods can be used for transition processing. The first method is that when the height difference is greater than 50 cm, the two layers of waterproof membranes are directly transition-bent according to the shape of the steps, the leveling layer 2 is interrupted at the vertical end surface of the steps, and the two layers of waterproof membranes are laid continuously. The special-shaped sheet siphon layer 5 is also transition-bent according to the shape of the steps, and a corner adhesive tape 12 located below is provided at the height difference positive corner of the special-shaped sheet siphon layer 5 to strengthen the bonding of the siphon layer at the height difference.
[0034] The second type is that the height difference is less than or equal to 50cm, and an additional structure is constructed to make a smooth transition for the height difference steps. A height difference slope 13 is provided between the leveling layer 2 and the waterproof membrane layer 3 at the height difference corner. The inclined surface of the height difference slope 13 is transitionally connected between the lower leveling layer 2 and the higher leveling layer 2, and the waterproof membrane and the special-shaped sheet siphon layer are laid normally on the height difference slope 13.
[0035] 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.
[0036] 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.
