Technical Field
The utility model belongs to the technical field of the rainwater garden, more specifically says, in particular to formula of sinking rainwater garden of abrupt slope structure.
Background
The rainwater garden is a naturally formed or artificially excavated shallow-recessed green land, and is used for gathering and absorbing rainwater from a roof or the ground, purifying the rainwater through the combined action of plants and sand, gradually infiltrating the rainwater into soil, conserving underground water, or supplementing urban water such as landscape water and toilet water. The rain flood control and rain water utilization facility is ecologically sustainable, and a conventional sunken rain water garden or a sunken green land can be made into a gentle slope form if the green land area is large.
Based on the above, the present inventors found that the following problems exist in use: when the existing sunken rainwater garden is arranged in a sponge city, the downward concave depth side slope is steep due to the limitation of the area of the city region, and the landslide phenomenon easily occurs on the original soil leveling layer, so that the attractiveness of the rainwater garden is influenced.
Therefore, in view of the above, research and improvement are made on the existing structure and defects, and a sunken rainwater garden with a steep slope structure is provided, so as to achieve the purpose of higher practical value.
SUMMERY OF THE UTILITY MODEL
