< r.: b br > b br >The construction of garden drainage boards is conducive to improving the urban environment, building a resource-saving, environment-friendly society, and saving Urban greening land can improve the urban heat island phenomenon and save air-conditioning electricity bills for top-floor business buildings and residents. Rooftop garden landscapes and rooftop gardens not only increase urban greening area and green landscapes, allowing citizens to enjoy more colorful garden scenery, but also have significant ecological and environmental effects. Roof gardens are a form of greening on the roof of a building that is isolated from the earth by planting plants and setting up landscapes. Therefore, when water storage and drainage boards are used on building roofs and green landscapes, they should be set up with interlayer structures to solve the technical connection of roof garden landscapes. The problem is that the drainage method on the roof of the building is a scattered water drainage method. When it is discharged into the downpipe, the planted soil and water accumulated in the drainage board and rainy season drainage must be filtered and the muddy water can be discharged into the downpipe, and it must be blocked. Plant roots cannot connect to underground capillary water pipes.

b br >Without the rising effect of groundwater, the water required for plants grown on the roof depends entirely on natural precipitation and irrigation. There must be a layer of storage and drainage structure and a structure to remove accumulated water. Therefore, the water storage Drainage boards came into being. Due to the limitations of the building and roof planting loads, the interlayer structure must have sufficient bearing capacity. The soil layer on the roof for planting is shallow, the capacity of effective soil water is small, and the soil is easy to dry. Light nutrient planting soil must be used, and drainage is stored. The application of plastic drainage boards solves this plastic drainage board problem.
