The rainwater left on the surface of the high-pressure drainage anisotropic sheet can be easily absorbed by the soil, so that the remaining rainwater can be used for vegetation growth. At the same time, the cross drainage groove can divide the vegetation layer on the upper surface into four areas, so that the rainwater in the four areas can quickly pass through the geotextile and enter the cross drainage groove through the multiple water inlet holes above the cross drainage groove for discharge, which solves the problem that rainwater is discharged into the rainwater drainage pipe through the perforated drainage pipe, but the rainwater stored in the rainwater drainage pipe is inconvenient to provide the required water to the plants.

Drainage pipes are installed at the four outermost corners where the cross drainage grooves are connected, and these drainage pipes will eventually converge into the water storage barrel for storage. Because the water storage barrel is arranged below the cross drainage groove, rainwater can quickly enter the water storage barrel through the water pressure to complete rapid drainage, and can be stored for subsequent use. In addition, the water outlet pipe installed at the upper end of the water storage barrel will discharge the rainwater in the water storage barrel into the river through the water outlet pipe after the water storage barrel reaches the water level line. The one-way valve outside the water outlet pipe ensures that only the rainwater in the water storage barrel can be discharged into the river without backflow. The water outlet pipe ensures that the water storage barrel can be continuously drained without overflowing and being unable to drain. This solves the problem that the rainwater can only be drained under the action of gravity by the inclined setting of the rainwater drainage pipe, but the drainage effect is slow when there is a lot of rain.

DETAILED DESCRIPTION
[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Specific embodiment 1

The lower side wall of the waterproof layer 102 is fitted and connected with a substrate 103. The substrate 103 facilitates the installation of the drainage system. A water storage component 2 is installed on the lower side wall of the soil layer 101. The water storage component 2 can play the role of drainage and water storage, effectively providing moisture to the vegetation layer 1, and solving the problem that the existing rainwater cannot be effectively stored for the vegetation layer 1.
[0031] Specifically, the lower side wall of the soil layer 101 is fitted and connected to the geotextile 201, which protects the equipment below to prevent soil from falling. The lower side wall of the geotextile 201 is fitted and connected to the high-pressure-resistant drainage special-shaped sheet 202, which is convenient for better protection of the high-pressure-resistant drainage special-shaped sheet 202. The lower side wall of the high-pressure-resistant drainage special-shaped sheet 202 is fitted and connected to the protective layer 204, and the protective layer 204 protects the cross drainage groove 203.

[0032] Furthermore, the high pressure-resistant drainage special-shaped sheet 202 is arranged in a double layer, so that the high pressure-resistant drainage special-shaped sheet 202 has the functions of water storage and drainage. The lower side wall of the protective layer 204 is fitted and connected to the waterproof layer 102. At the same time, a plurality of water inlet holes 203a are opened on the upper surface of the cross drainage groove 203 to facilitate rainwater to quickly enter the cross drainage groove 203.
[0033] The operation process of this embodiment is as follows: after rainwater falls, it passes through the vegetation layer 1 and the soil layer 101 and then the geotextile 201 and falls on the high pressure-resistant drainage anisotropic sheet 202. The geotextile 201 can filter the silt and impurities in the soil to prevent the silt from falling and causing the cross drainage groove 203 to be blocked. Because the high pressure-resistant drainage anisotropic sheet 202 is arranged in two layers, it can drain and store water more effectively. The rainwater left on the surface of the high pressure-resistant drainage anisotropic sheet 202 can be easily absorbed by the soil layer 101, so that the remaining rainwater can be used for the growth of the vegetation layer 1. At the same time, the cross drainage groove 203 can divide the vegetation layer 1 on the upper surface into four areas, so that the rainwater in the four areas can quickly pass through the geotextile 201 and enter the cross drainage groove 203 through the multiple water inlet holes 203a in the upper part of the cross drainage groove 203 to be discharged. Specific embodiment 2

The water outlet end of the drain pipe 303 is sealed and connected to the water storage barrel 301, so that rainwater can be discharged into the water storage barrel 301 through the drain pipe 303. A water outlet pipe 307 is installed at the water outlet of the water storage barrel 301. At the same time, the water outlet pipe 307 is set at the safe water level position of the water storage barrel 301, and the water outlet end of the water outlet pipe 307 is connected to the river flow. A one-way valve 307a is installed on the outer wall of the water outlet pipe 307, and the one-way valve 307a can prevent the backflow of the river flow.
[0037] Furthermore, a mounting frame 302a is installed on the upper side wall of the water storage barrel 301, and the mounting frame 302a is convenient for the installation of the micro water pump 302. The water storage barrel 301 is bolted to the micro water pump 302 through the mounting frame 302a, and the micro water pump 302 is fixed to facilitate pumping water. The input end of the micro water pump 302 is electrically connected to the output end of the controller to facilitate the control of the start of the micro water pump 302. The water inlet end of the micro water pump 302 is sealed and connected to the water inlet pipe 304, and the inlet The water inlet end of the water pipe 304 is arranged in the water storage barrel 301, which is convenient for extracting rainwater from the water storage barrel 301 for spraying. The water outlet end of the micro water pump 302 is installed with a transport pipe 305. The transport pipe 305 is convenient for transporting rainwater to the shower head 306 for spraying.

Drainage pipes 303 are installed at the four outermost corners where the cross drainage grooves 203 are connected, and these drainage pipes 303 will eventually converge into the water storage barrel 301 for storage. Because the water storage barrel 301 is arranged below the cross drainage grooves 203, rainwater will quickly enter the water storage barrel 301 through the effect of water pressure, complete rapid drainage, and store it for subsequent use. In addition, the water outlet pipe 307 installed at the upper end of the water storage barrel 301 will make the water storage barrel 301 reach this water level after the water storage barrel 301 reaches this water level.
