Description

A rainwater storage device in a landscape garden

technical field

The invention relates to the field of rainwater storage, in particular to a rainwater storage device in landscape gardens.

Background technique

Landscape architecture is a beautiful natural environment and landscape created by transforming the terrain (or further building mountains, stacking stones, and water management), planting trees and flowers, building buildings, and arranging garden roads by using engineering technology and artistic means in a certain area. The recreational area is called a garden. It is unique among traditional Chinese architecture, and it is the classical garden architecture that has made great achievements. An art form in traditional Chinese culture, which is deeply influenced by traditional "ritual and music" culture. Through the terrain, landscape, buildings, flowers and trees, etc. as the carrier, it sets off the spiritual culture of the human subject. Garden has many extended concepts, such as garden community, garden street, garden city (ecological city), national garden county and so on. The modern lifestyle and living environment have urgent functional and artistic requirements for gardens. It plays an increasingly important role in our modern life and the future direction of people's development.

At present, the drainage of landscape gardens mainly adopts ditch drainage. Ditch drainage includes open ditch and hidden ditch. In rainy weather, the water on the surface of the park is collected into the ditch, and then drained from the sewer, or there is a large pond in the garden, and the rainwater is discharged into the pond. The water in the pond can be used to irrigate the vegetation on sunny days. Since the ground in the garden is covered with turf and soil, the water flowing into the ditches or ponds after being washed by rainwater is turbid, and there are impurities such as leaves, branches, grass stems, etc. More, even the water in the ditch is accompanied by gravels, etc. If it is directly discharged into the sewer, the inspection well cover at the mouth of the sewer will be easily blocked, and it will be directly discharged into the pond to cause the pollution of the pond; and rainwater is a rich Fresh water resources, global fresh water resources are very tight, if the rainwater is discharged directly into the sewer, it is also a great waste, therefore, it is necessary to collect the rainwater in the garden and use it for watering trees in sunny days.

Existing rainwater collection devices used in landscape gardens usually include a rainwater storage tank, which is connected to a ditch on the ground, and the bottom of the rainwater storage tank is connected to a water tower through a water pipe, and a rainwater storage tank is installed in the rainwater storage tank. There is a filtering device, so that the rainwater falling into the garden can be filtered and stored in the water tower for use in sunny days.

But there are following defects in the rainwater storage device in the existing landscape gardens:

(1) The rainwater filtration of the existing rainwater collection device is all carried out in the rainwater storage tank, although it can also play a better filtering effect like this, but it is easy to make the water storage pipes for collecting rainwater and the water collection on the ground The ditch is blocked, which makes the rainwater storage effect not good. At the same time, it is difficult to clean the impurities after filtration, which is not conducive to the long-term use of the device;

(2) The existing rainwater collection device usually filters and purifies all the rainwater before reusing it, but for some water that does not require high water quality, such as watering trees, it is not necessary to perform deep purification, otherwise the purification will be increased cost, resulting in a waste of funds;

(3) The existing rainwater harvesting device usually sprays the collected rainwater on the surface when watering the trees, but this will cause a large proportion of the water to evaporate directly and cannot be absorbed by trees and flowers, so that the utilization of water resources is insufficient.
