Problems solved by technology

However, the use of sprinkler irrigation has disadvantages such as high transportation costs, limited spraying height, and waste of water resources.
[0003] However, the existing slope restoration technologies focus more on the planting and cultivation techniques of vegetation, but often ignore the full use of precipitation resources and the scientific and reasonable allocation of precipitation resources in time and space to enhance the slope vegetation restoration system against extreme drought events. The ability to reduce the cost of management and maintenance of slope vegetation restoration system and improve the survival rate of vegetation

Embodiment 1

[0025] Such as figure 1 As shown, Embodiment 1 of the present invention provides a planting system for slope ecological restoration, including: a water storage tank 2 embedded in the inclined section of the slope soil 1, and a water storage tank 2 along the inclined section of the slope soil 1 A plurality of implants 3 evenly distributed in the soil body 1 above the water storage tank 2, the implants 3 include: a planting groove made of concrete, the lower part of which is embedded in the soil body 1, and the bottom of which passes through the pipeline 1 and the water storage tank 2 Connected; the pipeline II entrance at the bottom of the planting tank is provided with a water-permeable retaining layer for preventing the loss of plant seeds in the sand; in order to enhance the survival rate of the plants, the planting tank is provided with a mesh bag 33 woven by perishable plant rhizomes, and the mesh bag 33 The soil is filled inside; it also includes an irrigation structure, ...

Embodiment 2

[0029] On the basis of Example 1, further, it also includes a sediment treatment structure, including a silt pump 7, which is arranged on the top of the soil body 1 along the slope, and is located on one side of the diversion channel 5, and the inlet end of the silt pump 7 is connected with a pass through The pipeline II9 communicates with the bottom of the water storage tank 2, and the outlet end of the sludge pump 7 is located above the drainage channel 5.

[0030] Further, the permeable soil retaining layer includes a baffle 31 arranged at the bottom of the planting tank, the baffle 31 is arched, and its concave surface is set upward, and the baffle 31 is provided with dense water seepage holes.

[0031] Furthermore, in order to further prevent sediment from entering the reservoir 2 , a geotextile layer 32 is provided on the baffle 31 .

[0032] Further, in order to enhance the survival rate of the plants and provide certain nutrients to the plants, plant straws 34 are laid...

Abstract

The invention relates to a vegetation system for slope ecological restoration. The system comprises: a water storage tank buried in an inclined section of a slope soil body; and a plurality of planting bodies which are uniformly distributed in the soil body above the water storage tank along the inclined section of the side slope soil body. The planting bodies comprise: planting grooves which aremade of concrete, wherein the lower parts of the planting grooves are buried in the soil body, and the bottoms of the planting grooves are communicated with the water storage tank through pipelines; apermeable soil retaining layer which is arranged at a pipeline inlet in the bottom of each planting groove and used for preventing seeds in the sandy soil from running off; a mesh bag which is formedby weaving rhizomes of perishable plants, is arranged in the planting groove and is used for filling the soil body; and an irrigation structure, wherein an inlet of the irrigation structure is formedin the water storage tank, and an outlet of the irrigation structure is formed above the implant and used for supplying water to the planting grooves. According to the device, plants planted on the side slope are irrigated during drought, rainwater is collected and stored when the rainwater is too much, the whole system forms a complete cycle, and therefore ecological restoration of the side slope is further assisted, and ecological stability of the side slope is guaranteed.

Description

technical field [0001] The invention relates to the technical field of slope restoration, in particular to a vegetation system for ecological restoration of slopes. Background technique [0002] Slope vegetation restoration can protect the slope surface from weathering, erosion, and rain erosion under natural conditions, and ensure the stability of the slope. It is an important part of the slope prevention and control project. For slopes in areas with insufficient precipitation, water shortage is the most important limiting factor for slope vegetation restoration. However, the use of sprinkler irrigation has disadvantages such as high transportation costs, limited spraying height, and waste of water resources. [0003] However, the existing slope restoration technologies focus more on the planting and cultivation techniques of vegetation, but often ignore the full use of precipitation resources and the scientific and reasonable allocation of precipitation resources in time ...
