Problems solved by technology

[0003] Aiming at the defects of poor rainwater treatment ability, single landscape and poor biodiversity in the prior art, the present invention discloses a rain garden and its construction method which is beneficial to improve biodiversity. The species of insects provide a habitat with excellent environment to build a complete small ecosystem, which not only improves the ornamental value of the rain garden, but also has a good rainwater storage capacity, which can effectively adjust the speed of rainwater into the municipal official network in rainy seasons , thereby improving the ability to deal with rain and floods, and helping to alleviate urban waterlogging

Embodiment approach 1

[0031] This embodiment, as the basic embodiment of the present invention, discloses a rain garden that is beneficial to improving biodiversity, and its specific structure is as follows: figure 1 and figure 2 As shown, including the foundation pit, there are 4 layers of steps in it, and in order from top to bottom, the steps of all levels shrink toward the central area, so that the cross section of the foundation pit is set in a bowl shape; the foundation pit The bottom is fixed with a drainage pipe 4, and the surface of the drainage pipe 4 is uniformly provided with a plurality of water inlet holes 5. At the same time, one end of the drainage pipe 4 is connected with the municipal rainwater pipe network, and the other end is sealed; at the same time, a water guide pipe is also arranged at the bottom of the foundation pit 6. The other end of the water guide pipe 6 communicates with the sump 7 fixed under the eaves, and the corresponding interface is treated with anti-leakage; ...

Embodiment approach 2

[0036] This embodiment, as the basic embodiment of the present invention, discloses a method for constructing a rain garden that is conducive to improving biodiversity, which includes the following steps:

[0037] S1. According to the construction plan, install the sump on the front and rear eaves of the building at the designated location. The specifications of the sump can be flexibly selected according to actual needs. The two ends of the sump are 10cm longer than the eaves. After installation, the sump is treated with anti-seepage;

[0038] S2. A galvanized steel pipe with a diameter of 5 cm is installed at the lower end of the sump installed in step S1 as a diversion pipe, and the connection between the upper end and the sump needs to be treated with anti-seepage;

[0039]S3. According to the actual situation, select the construction location of the green space around the building, and set the line for excavation at the construction location. It is better to choose a low-l...

Abstract

The invention discloses a rainwater garden beneficial to improvement of biological diversity and a construction method thereof. The rainwater garden comprises a foundation pit, wherein the foundation pit is sequentially filled with a planting soil layer, a gravel layer and a pebble layer, a water drainage pipe and a water guide pipe are buried in the pebble layer, the water drainage pipe is communicated with a municipal pipe network, and a plurality of water inlet holes are formed in the water drainage pipe; the water guide pipe is connected with a water collection tank located under an eave; and the planting soil layer is used for planting various ornamental plants, the gravel layer and the pebble layer are used for filtering rainwater, the rainwater is accumulated while the redundant rainwater is guided to be drained to the municipal pipe network, and normal growth of the ornamental plants is guaranteed. According to the rainwater garden, a small ecological circulation system is formed through reasonable arrangement of a plurality of functional layers, a place for the small animals such as insects to live is provided, and meanwhile the ornamental value of the garden can be improved; and the flow speed of the rainwater entering the municipal pipe network can be adjusted, urban waterlogging is relieved, the rainwater is recycled, and the water consumption of the garden is reduced.

Description

technical field [0001] The invention relates to the technical field of landscaping, in particular to a rain garden and a construction method thereof which are beneficial to improving biological diversity. Background technique [0002] As a kind of artificial landscape, green space plays an important role in urban greening, but in the prior art, green space is generally only composed of a single plant, and its biodiversity is limited; due to the continuous convergence of urban landscape, its ornamental value is also limited. To improve the ornamental value of green spaces, people usually add landscapes such as squares, fountains or artificial ponds, rivers, etc., but the above landscapes do not have any ecological functions, and at the same time encroach on the habitat of small urban animals. And the smooth surface intensifies the speed of surface runoff convergence, and eventually causes urban waterlogging to affect the environment around the green space, and its flood contr...
