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, this embodiment provides a side slope ecological protection device, which includes a plurality of side slope protection units 2 installed on the side slope 1, the side slope protection unit 2 includes a water diversion mechanism and a protective grille 3, and a river channel 9 is provided with The water supply mechanism for the water supply mechanism of the water supply mechanism, the water supply mechanism includes a water delivery pipe 6 and a water distribution pipe 7, the water supply mechanism is installed at the water inlet end of the water delivery pipe 6, and the water delivery pipe 6 is inclined upward along the side slope 1 until it reaches the protective grille 3. The upper part is then connected to 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 extending direction. The water outlet slot 16 is facing the protective g...

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 that is stepped from top to bottom. This design can improve the stability of the ecological slope protection, and can also prevent soil erosion and improve the ecological environment. 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 irrigation of the slope protection plants in each grid slot, the stepped protection grid 3 includes a plurality of supporting walls 3.1 from top to bottom. The length direction of the supporting wall 3.1 is related to the slope. The length direction of 1 is the same. A grid groove 10 is formed between the supporting walls 3.1. The grid groove 10 is filled with soil and planted with slope protection plants. 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 supporting wall 3.1 is uniformly provided with a plurality of diverting holes 11 which communicate with the water flow distribution channel along the length direction of the supporting wall 3.1.

Abstract

The invention relates to the technical field of slope protection, and discloses a slope ecological protection device which comprises a plurality of slope protection units arranged on a slope. The slope protection units comprise water diversion mechanisms and protection grids, water feeding mechanisms for supplying water to the water diversion mechanisms are arranged in a river channel, each waterdiversion mechanism comprises a water delivery pipe and a water distribution pipe, and the water feeding mechanisms are arranged at the water inlet ends of the water delivery pipes, each water delivery pipe is connected with the corresponding water distribution pipe after being inclined upwards along a side slope until reaching the upper part of the corresponding protection grid, the water distribution pipes are flexible plastic water pipes, the water distribution pipes are inclined downwards towards the extending direction of the water distribution pipes, a plurality of water outlet slits areformed in the water distribution pipes in the length direction of the water distribution pipes, and the water outlet slits are aligned to the protection grids below the water distribution pipes. According to the slope ecological protection device provided by the invention, the water flow in the river channel can be conveyed to the upper part of the slope through a pipeline, watering for slope protection plants on a larger area on the slope can be better cared, the growth requirement of the slope protection plants is guaranteed, and thus a better slope protection effect is achieved.

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 highlights the harmonious coexistence between humans and rivers. It can fully reflect the characteristics of water biodiversity and localization. Its core is to comprehensively consider the overall environment, safety and water resources around the river. , The slope protection plants on the river slope should choose plants with developed roots and strong soil-fixing ability, so as to prevent the river from scouring the slope for a long time and accelerating the soil erosion of the edge. The common slope protection plants planted on the side slopes have strong drought resistance, but the problem is that such slope protection plants are not waterlogging-tolerant. Slope protection plants that are not waterlogging-tolerant are difficult to s...
