Gardening intensive water storage and drainage method

Abstract

A gardening intensive water storage and drainage method relates to drainage design method. The gardening intensive water storage and drainage method comprises two steps of, firstly, during residential greening space planning and park greening space planning, selecting low-lying areas and surrounding areas as the central greening space or appropriately reforming existing terrains into an area with a relatively high circumferential level; secondly enabling the circumference of the central greening space to connect with or surround the main roads of a residential district or a park. According to the gardening intensive water storage and drainage method, through terrain reformation, the garden greening space can obtain the functions of water storage and drainage and groundwater replenishing, municipal drainage burden of gardens in rain days can be released, the functionality and the environmental properties of urban gardens can be greatly enhanced, and a large quantity of water resources can be saved.

Description

technical field [0001] The invention relates to a drainage design method, in particular to a garden cohesive storage and drainage method. Background technique [0002] With the continuous development of society, the urbanization process of the city is getting faster and faster, which leads to the natural green land, farmland and ponds around the city being filled into urban construction land, and the urban land is characterized by the extensive use of reinforced concrete Covering the soil surface, in this environment, rainwater cannot penetrate into the ground, and when it rains, it can only be drained through municipal drainage pipes. Although the existing municipal drainage facilities are constantly improving, they still cannot meet the needs of rainstorms and The city’s drainage needs during heavy rains, and it is a huge waste to directly discharge these natural fresh water resources into the sewer without making good use of them. At present, in many cities, the drai...

Problems solved by technology

[0003] The purpose of the present invention is to provide a method for cohesive storage and drainage of gardens, which solves the problem that in many cities, the drainage design of gardens does not take this aspect into consideration. Usually, in order to ensure that the green space does not accumulate water, the elevation of the green space is often designed It is higher than the surrounding roads, allowing the accumulated water in the green space to be discharged into the municipal sewer, which increases the pressure on the municipal drainage system. When the storm water level is high, it will cause serious water accumulation in the city. At the same time, some garden design pond landscapes , At this time, water needs to be taken from the municipal water supply, and the bottom of the landscape has been treated to prevent water from seeping into the ground. question
