[0022] The present application is further described below in conjunction with specific embodiments and drawings.

[0023] refer to Figure 1 As shown, an invisible dispersion structure applied to the exterior wall of a building includes an exterior wall 1, a base 2, a waterproof layer 3, a dispersion composite soil layer and a retaining wall 11. The dispersion composite soil layer includes a water-blocking base layer 4, a gravel soil layer 5, a drainage cushion layer 6, a planting soil layer 7, a covering soil layer 8, vegetation 9 and a drainage pipe 10.

[0024] The outer wall 1 is divided into an indoor area 100 and an outdoor area 200, and the water dispersion structure is located at the outdoor area 200. A waterproof layer 3 is provided at the outer wall root of the outer wall 1, and the waterproof layer 3 prevents rainwater from penetrating the wall and the wall root. A footing 2 is provided at the bottom of the waterproof layer 3, and the footing 2 is made of a flexible sealing material. The footing 2 is also used for water blocking and waterproofing, and forms a structure for preventing accumulated water from flowing out. The waterproof layer 3 can cover the footing 2, or it can be located only above the footing 2.

[0025] A water-dispersing composite soil layer is provided outside the waterproof layer 3, and the water-dispersing composite soil layer forms a structure that is conducive to water dispersion and drainage outside the waterproof layer 3, and can also be used for vegetation planting. A retaining wall 11 is provided outside the water-dispersing composite soil layer, and the retaining wall 11 is used to maintain the entire composite soil layer and maintain the thickness of the soil layer.

[0026] The width (outward span) of the water dispersion composite soil layer is 0.8m to 1.2m, preferably 1m. The water dispersion composite soil layer includes a water blocking base layer 4, a gravel soil layer 5, a drainage cushion layer 6, a planting soil layer 7 and a covering soil layer 8 arranged layer by layer from bottom to top.

[0027] The water-blocking base layer 4 is preferably made of concrete, and has a downward slope outwardly, and the slope of the water-blocking base layer 4 is 3% to 5%, preferably 4%. The water-blocking base layer 4 is used to prevent rainwater from infiltrating and affecting the stability of the foundation, and the slope on it is conducive to the outflow of rainwater and avoids rainwater from gathering there. The height of the plinth 2 is slightly higher than the water-blocking base layer 4.

[0028] The gravel soil layer 5 needs to be compacted to protect the water-blocking base layer 4 and cooperate with the water-blocking base layer 4 to block soil particles and prevent the loss of soil particles in the upper planting soil layer.

[0029] The drainage cushion layer 6 is made of gravel and pebbles, and has a strong drainage effect. The drainage cushion layer 6 is provided with a downward slope outwardly, and the slope of the drainage cushion layer 6 is 2% to 4%, and the preferred slope bottom is 3%, which is conducive to the outflow of rainwater and avoids the rainwater from gathering there.

[0030] A downward guide groove is provided in the drainage cushion layer 6, and the guide groove can be a hollow pipe or can be higher than the cushion layer surface. The guide groove can guide rainwater so that it is convenient for rainwater to flow outward.

[0031] A drainage pipe 10 is provided in the water-dispersing composite soil layer, the upper end of the drainage pipe 10 extends to the planting soil layer 7, and the lower end of the drainage pipe 10 extends to the drainage cushion layer 6. Thus, the drainage pipe 10 can directly drain the rainwater in the planting soil layer 7 to the drainage cushion layer 6 without the need for slow seepage of the soil body, and has a better drainage effect when the rainwater flow is large.

[0032] The drainage pipes 10 are arranged at intervals to ensure uniform drainage. The lower end of the drainage pipe 10 extends to the guide groove of the drainage cushion layer 6, and the drainage effect of the drainage pipe 10 can be further optimized with the help of the guide groove. A permeable net is provided at the upper end of the drainage pipe 10 to prevent planting soil from entering the drainage pipe 10. A drainage hole is provided at the lower end of the drainage pipe 10 to achieve water discharge.

[0033] The planting soil layer 7 is used to absorb rainwater and maintain plant growth. The covering soil layer 8 is located on the upper part of the planting soil to prevent dust from causing soil particle loss. Vegetation 9 is planted on the planting soil layer 7 and the covering soil layer 8. Oligotrophic plants are planted in the soil. Considering the height of the planting soil, the plant root length is selected to be about 20 cm. The height of the waterproof layer 3 is slightly higher than the covering soil layer 8.

[0034] The aforementioned basic examples and their further selected examples can be freely combined to form multiple embodiments, all of which are embodiments that can be adopted and claimed for protection in this application. In the scheme of this application, each selected example can be arbitrarily combined with any other basic examples and selected examples.
