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 node structure of a rainwater siphon collection and drainage system for a planting roof includes a planting top plate 1, a leveling layer 2, a waterproof membrane layer 3, a root-piercing resistant waterproof membrane layer 4, a special-shaped sheet siphon layer 5, a geotextile filter layer 6, a planting layer 7, a high-span protruding structure 8, a low-span protruding structure 9, a through-plate pipe 10, an adhesive tape 11, a sealing mortar 12, a through-wall pipe 13, a geotextile wrap 14, a sealing paste 15 and a wall 16.

[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 is arranged above the root-penetration-resistant waterproofing membrane layer 4, and the special-shaped sheet siphon layer 5 is fully spread above 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.

[0027] A geotextile filter layer 6 is provided on the siphon layer 5 of the special-shaped sheet to block the planting layer 7. The geotextile filter layer 6 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 special-shaped sheet. The planting layer 7 is a soil layer for planting vegetation.

[0028] refer to Figure 2As shown, it is a node of the inner corner of a high-span protruding structure. The waterproof membrane layer 3, the root-penetration-resistant waterproof membrane layer 4, the special-shaped sheet siphon layer 5 and the geotextile filter layer 6 are turned up at the inner corner to the high-span protruding structure 8. The end of the geotextile filter layer 6 extends relatively out of the waterproof membrane layer 3, the root-penetration-resistant waterproof membrane layer 4 and the special-shaped sheet siphon layer 5. The end of the geotextile filter layer 6 is fixedly connected to the high-span protruding structure 8 by brushing adhesive.

[0029] At the high-span protruding structure 8 (such as ventilation shaft, light well, civil air defense entrance and exit, and lifting plate position), the siphon layer 5 of the special-shaped sheet needs to be turned up, and the turning height is about 1200mm. The two layers of waterproof membrane and geotextile are turned up together with the polymer special-shaped sheet at this position. The turning height of the waterproof membrane is the same as that of the polymer special-shaped sheet, and the turning height of the geotextile is 100mm higher than that of the polymer special-shaped sheet. Since the height of the high-span protruding structure 8 is higher than the planting layer 7, it is only necessary to perform a certain degree of treatment on the inner corner to ensure the waterproof, root puncture resistance, drainage and sediment filtration functions of the inner corner, and finally use the geotextile for edge sealing.

[0030] refer to Figure 3 As shown, it is a positive corner node of a low-span protruding structure, and a leveling layer 2, a waterproof roll material layer 3, a root-penetration-resistant waterproof roll material layer 4, a special-shaped sheet siphon layer 5, a geotextile filter layer 6 and a planting layer 7 are arranged on the low-span protruding structure 9 from the inside to the outside. Since the height of the low-span protruding structure 9 is lower than the planting layer 7, the entire low-span protruding structure needs to be processed to ensure that the entire action surface below the planting layer 7 has the functions of waterproofing, root-penetration resistance, water storage and drainage, and sediment filtration.

[0031] For the special-shaped sheet siphon layer 5 at the protruding structure, the special-shaped sheet siphon layer 5 on the planting top plate 1 is pressed below by the special-shaped sheet siphon layer 5 on the protruding structure, so as to realize the connection and fixation of the special-shaped sheet siphon layer 5 in two arrangement directions. Alternatively, the special-shaped sheet siphon layer 5 on the planting top plate 1 is spliced ​​and connected with the special-shaped sheet siphon layer 5 on the protruding structure, and the bottom of the splicing seam is sealed with an adhesive tape.

[0032] refer to Figure 4 As shown, it is a through-plate pipe node, the waterproof roll material layer 3, the root puncture resistant waterproof roll material layer 4 and the geotextile filter layer 6 are turned up to the through-plate pipe 10 at the corner to ensure the waterproof, root puncture resistant and sediment filtration functions at the corner. Due to the arc shape and small area of ​​the pipe wall, the special-shaped sheet siphon layer 5 does not need to be turned up. An adhesive tape 11 located at the corner is provided below the special-shaped sheet siphon layer 5 to reinforce the special-shaped sheet at the corner.

[0033] A sealing mortar 12 is provided between the waterproof membrane layer 3 and the through-plate pipe 10, and the end of the geotextile filter layer 6 is fixedly connected to the end of the root-penetration-resistant waterproof membrane layer 4 by adhesive, thereby achieving sealing at the through-plate pipe 10 and achieving protective shielding of the seal.

[0034] refer to Figure 5 As shown, it is a through-wall pipe node. The through-wall pipe 13 also passes through the leveling layer 2, waterproof roll material layer 3, root puncture-resistant waterproof roll material layer 4, special-shaped sheet siphon layer 5 and geotextile filter layer 6 arranged on the wall 16 from the inside to the outside. Since the through-wall pipe is arranged horizontally, the waterproof hidden danger faced is small, so a sealing paste 15 is provided on the outside of the through-wall pipe 13 for simple sealing. At the same time, a geotextile wrapping sleeve 14 located between the planting layer 7 and the geotextile filter layer is provided on the through-wall pipe 13 to prevent mud and sand from entering the gap of the pipe. An adhesive tape 11 is provided at the interruption below the special-shaped sheet siphon layer 5 to reinforce the special-shaped sheet at the interruption.

[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.
