Rainwater garden using structural beams for carrying out rainwater storage and retention and automatic irrigation

Abstract

The invention relates to the technical field of municipal engineering, and discloses a rainwater garden using structural beams for carrying out rainwater storage and retention and automatic irrigation. The rainwater garden includes a planting filtration layer, a structural seepage and storage layer, an automatic rainwater irrigation system and a rainwater storage and retention automatic regulatingsystem. According to the rainwater garden using the structural beams for carrying out the rainwater storage and retention and the automatic irrigation, a top-plate structural system of a building isadopted, large earth-covered garden green land is arranged on the surface of the planting filtration layer, no terrain limit exists, landscape effects are well built, adequate rainwater seepage and retention area is provided, and the sponge effect is better; the structural seepage and storage layer has the function of a large-capacity water storage pool, water does not easily evaporate, and the effective utilization rate of rainwater is high; the green land is irrigated through a submerged pump and a rainwater irrigation pipe net system, rainwater recycling is achieved, and the management costis saved; the planting filtration layer is good at permeability and does not generate ponding so that growth of green plants and building of landscape diversity can be promoted; the ponding is not generated, therefore, breeding of mosquitoes and other insects is avoided, sanitary environment is ensured, and management is easy to carry out.

Description

technical field [0001] The invention relates to the technical field of municipal engineering, in particular to a rainwater garden that utilizes structural beams and slabs for rainwater storage and automatic watering. Background technique [0002] Sponge city is an urban construction goal that my country has vigorously promoted after green buildings to strengthen water conservation and intensive use, protect and improve the urban ecological environment, and promote the construction of ecological civilization. Sponge city is a new generation of urban stormwater management concept, which means that the city has good "elasticity" in adapting to environmental changes and responding to natural disasters caused by rainwater. It can also be called "water elastic city", that is, through the maximum Make maximum use of natural environments such as grasslands, forests, and lakes to absorb a large amount of rainwater, and adopt artificial technical measures such as water seepage, stagna...

AI Technical Summary

Problems solved by technology

[0006] (1) The amount of retained rainwater in the subsidence section is extremely limited, and waterlogging is prone to occur, which not only affects the growth of green plants, but also affects the landscape effect;

[0007] (2) The occurrence of stagnant water will easily lead to the breeding of mosquitoes and affect the environmental sanitation;

[0008] (3) It is difficult to manage the use period, and it is even difficult to continue;

[0009] (4) Due to terrain constraints, the area and scale of the rain garden is extremely limited, and it is difficult to set up the form of depressions;

[0010] (5) The vertical supports on both sides of the shallow groove affect the appearance;

[0011] (6) The sunken garden has poor visual effects, especially in small areas, it is easy to be blocked
