Problems solved by technology

Common slope protection plants planted on slopes are very drought-resistant, but the problem is that such slope protection plants are not resistant to waterlogging. Therefore, in the event of river flooding, the water flow will submerge the slope protection plants on the slope. Slope protection plants that are not resistant to waterlogging are difficult to survive. In addition, rising water levels will affect the stability of the slope soil layer, resulting in soil erosion and protection failure. Therefore, planting waterlogging-tolerant plants on the slope can prevent plants from being damaged by water Long-term submersion will cause water and soil erosion, but this kind of waterlogging-tolerant plants will also have the problem of drought tolerance, and long-term water shortage will also affect the survival of this type of slope protection plants
[0003] In the current situation, in order to ensure the growth of waterlogging-tolerant plants on the slope, it is necessary to ensure the timely water supply for this type of plants. When using the traditional way of diverting water to the top of the slope, the pressure of the water flow increases with the length of the pipeline. The extension gradually decreases, so it is difficult to achieve the effect of evenly distributing the water flow
In addition, the traditional protective grille is a solid structure of cast-in-place concrete. With this design, when the slope surface is uneven, the water flow will flow toward the lower place. Therefore, for the slope protection plants on the high slope surface It is difficult to achieve the effect of watering, which is not conducive to achieving uniform distribution of water flow and uniform watering of slope protection plants

Embodiment 1

[0049] like Figure 1-Figure 10 As shown, the present embodiment provides a slope ecological protection device, including a plurality of slope protection units 2 installed on the slope 1, the slope protection unit 2 includes a water diversion mechanism and a protective grille 3, and the river channel 9 is provided with The water feeding mechanism that supplies water to the water diversion mechanism. The water diversion mechanism includes a water delivery pipe 6 and a water distribution pipe 7. The water delivery mechanism is installed at the water inlet end of the water delivery pipe 6. The water delivery pipe 6 is inclined upward along the side slope 1 until it reaches the bottom of the protective grille 3. After the top, it is connected with the water distribution pipe 7. The water distribution pipe 7 is a flexible plastic water pipe. The water distribution pipe 7 is inclined downward toward its extension direction. The water distribution pipe 7 is provided with a plurality o...

Embodiment 2

[0057] This embodiment is optimized on the basis of the above-mentioned embodiment 1.

[0058] In order to achieve a better slope protection effect, the protective grille 3 is a stepped protective grille from top to bottom. This design can improve the stability of ecological slope protection, and can also prevent soil erosion and improve ecological protection. The role of the landscape, the stepped protective grille 3 intercepts step by step to reduce the risk of soil erosion and pollutants flowing into the river.

Embodiment 3

[0060] This embodiment is optimized on the basis of the above-mentioned embodiment 2.

[0061] In order to achieve a better water flow distribution effect and realize the watering of slope protection plants in each grid groove, the stepped protective grid 3 includes a plurality of support walls 3.1 from top to bottom, and the length direction of the support walls 3.1 is aligned with the side slope. The length direction of 1 is the same, the grid groove 10 is formed between the supporting walls 3.1, the grid groove 10 is filled with soil and slope protection plants are planted, each supporting wall 3.1 is a hollow structure, and the water flow distribution channel is formed in the supporting wall In 3.1, the retaining wall 3.1 is evenly provided with a plurality of distribution holes 11 in communication with the water distribution channel along the length direction of the retaining wall 3.1.

Abstract

The invention relates to the technical field of slope protection, and discloses a slope ecological protection device, which includes a plurality of slope protection units installed on the slope. The slope protection units include a water diversion mechanism and a protective grille. The water supply mechanism for water supply by the water diversion mechanism. The water diversion mechanism includes a water delivery pipe and a water distribution pipe. The water supply mechanism is installed at the water inlet end of the water delivery pipe. The water distribution pipe is a flexible plastic water pipe, and the water distribution pipe is inclined downward toward its extension direction. There are multiple water outlet slits along the length direction of the water distribution pipe on the water distribution pipe, and the water outlet seams are facing the protective grille located under the water distribution pipe; The slope ecological protection device provided by the present invention can transport the water flow in the river to the top of the slope through the pipeline, and can better take care of the watering of slope protection plants in a larger area on the slope, ensuring that the slope protection plants growth needs, so as to achieve better slope protection effect.

Description

technical field [0001] The invention relates to the technical field of slope protection, in particular to a slope ecological protection device. Background technique [0002] Ecological slope protection is a kind of hydrophilic project that demonstrates the harmonious coexistence between man and river nature. It can fully reflect the characteristics of aquatic biodiversity and localization. Its core is to comprehensively consider the overall environment, safety and water resources around the river. For the selection of slope protection plants on the river slope, the plants with developed root system and strong soil-fixing ability should be selected to prevent the river from scouring the slope for a long time and accelerate the soil erosion of the edge. Common slope protection plants planted on slopes are very drought-resistant, but the problem is that such slope protection plants are not resistant to waterlogging. Therefore, in the event of river flooding, the water flow will...
