Description

A multifunctional landscape flower bed based on rainwater regulation and storage

technical field

The utility model relates to the fields of water supply and drainage and gardening, in particular to a multifunctional landscape flower bed based on rainwater regulation and storage.

Background technique

In order to build an ecological city and a livable city, more and more cities pay attention to the construction of the ecological environment, especially the urban greening construction, such as street greening, community greening, parks, wetlands, etc., which are not only beautiful but also purify the urban air. These street greening, community greening, parks, wetlands, etc. are usually embodied by planted flowers and trees. Some are directly planted on the land, and some are further beautified by using cultivation containers. Landscape flower beds are one of the cultivation containers. It is not only beautiful, but also protects the growth of flowers and trees and creates a suitable growing environment for them. The existing landscape flower beds are usually irrigated by rainwater in the rainy season, but in the non-rainy season, the garden department needs to be irrigated by special personnel using fire water or sprinklers, which wastes manpower and material resources.

In addition, in the process of urbanization in my country, problems such as contradiction between supply and demand of water resources, flood disasters and water environment pollution occur frequently. Traditional stormwater drainage systems are unable to cope with the ever-increasing demands for flood control and water environmental protection. In order to solve such problems, drawing on the low-impact development (LID) model, my country proposes and promotes the concept of sponge city construction, in which rainwater storage and utilization has become an important means to alleviate the problem. As an available and suitable water resource, the collection, storage and utilization of initial rainwater is also a practical interpretation of the concept of sponge city. At present, cities and towns mostly use indirect utilization for rainwater collection and utilization, mainly including dispersed infiltration and centralized recharge. When these two technologies encounter large precipitation, the area of permeable bricks is limited, which will cause rainwater to infiltrate in time, poor drainage system, high energy consumption, poor initial purification effect, and evaporation of water on the urban ground. It is too large to realize the defects such as full utilization of water storage and water recycling.
