Description

Technical Field

[0001] The utility model relates to a high-steep slope suspended greening ecological device, belonging to the technical field of ecological restoration of high-steep slopes. Background Art

[0002] Due to engineering construction or mining development, the mountain is excavated, destroying the original vegetation of the mountain. The mountain is damaged to form exposed slopes, making it difficult for plants to survive and the ecosystem to recover. Especially the steep slopes have become barren land. With the country and the people paying more attention to ecological restoration, the greening of slopes has become a key research topic in engineering construction. At present, the existing slope greening methods mainly include soil covering greening of steps after slope cutting, soil covering greening of gentle slopes, greening of fish scale pits on gentle slopes, greening of stacked vegetation bags on gentle slopes, spraying of imported soil, spraying of vegetation concrete, planting of green by drilling, active net + vegetation bag greening and other technical methods. Compared with high and steep slopes (above 70°) that cannot be cut due to limited conditions (such as buildings on the top of the slope, the slope is close to the ecological red line, etc.), greening technical methods such as soil covering greening of gentle slopes, greening of fish scale pits on gentle slopes, and stacked vegetation bags on gentle slopes cannot be implemented. Greening methods such as spraying of imported soil and spraying of vegetation concrete have very poor effects. Technical methods such as drilling planting and active net + vegetation bag greening have relatively good effects, but the cost is very high and the construction is very difficult. Utility Model Content

[0003] In view of the above problems existing in the prior art, the purpose of the utility model is to provide a construction process for greening high and steep slopes which is simple in process, durable and stable, low in cost and effective, and can be applied to solve the problems raised in the above background technology.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A high and steep slope hanging greening ecological device, including a longevity bag body, a longevity bag fixing anchor rod, an active net, an active net fixing anchor rod, a support platform sandwich panel (or other weather-resistant panels), a water storage dish, insulation cotton, and a steel strand. The steel anchor rod is pre-rust-proofed, electroplated or painted. The active net is installed on a relatively flat slope surface (a part with a length of 1 meter and a height of 0.5 meters with a local protrusion or depression of no more than 10 centimeters) through the active net fixing anchor rod. The anchoring depth is 30 cm and the exposed 10 cm. The support The sandwich panel is placed horizontally in the active network, with one end close to the slope, forming an L-shaped greening platform with the slope. The water storage dish is placed horizontally on the greening platform. The longevity bag body is composed of three longevity bag units, with built-in nutrient soil, tightly placed side by side in the water storage dish, and close to the rock wall. The placed longevity bag body is wrapped with the insulation cotton. There are four longevity bag fixing anchor rods, two on each of the left and right sides of the longevity bag body. The steel strands are used to connect the longevity bag fixing anchor rods, and the insulation cotton is tightened and fixed in a Z shape. Climbing plants such as kudzu and creepers are planted or planted at the mouth of the longevity bag body. The above structure is installed on the high and steep slope at a certain horizontal and vertical spacing, and the biological characteristics of the plant, such as strong vitality, fast growth, developed rhizomes, and stem node tillering and regeneration roots, are used to control the irrigation water volume according to the seasonal temperature to achieve the purpose of quickly improving the slope greening rate.

[0006] Preferably, the longevity bag fixing anchor rods and the active net fixing anchor rods are steel bar anchor rods.

[0007] Preferably, the active mesh is a steel mesh or a wire mesh.

[0008] Preferably, a few small holes are pierced on the longevity bag at the position where the longevity bag body fits against the rock wall, so as to facilitate the roots of plants planted later to invade the cracks in the rock layer and take root and grow.

[0009] Compared with the existing technology, the utility model has the following advantages: using the support platform sandwich panel and active net to build a greening platform to carry the longevity bag to avoid the risk of the longevity bag falling, and using steel strands to fix the insulation cotton outside the longevity bag body to improve the cold and heat resistance effect; the above structure is installed on the high and steep slopes at a certain horizontal and vertical spacing, and the biological characteristics of plants such as strong vitality, fast growth rate, developed rhizomes, and stem node tillering and regeneration roots are used to achieve rapid greening of the slope. The ecological restoration structure in this scheme can be applied to high and steep slopes with steep slopes, stratification or cracks, providing a new ecological restoration structure for the greening work of high and steep slopes, and promoting the development of high and steep slope work.

The steel anchor rods 2 and 4 are pre-rust-proofed, electroplated or painted to form a protective film on the surface of the anchor rods, thereby preventing the anchor rods from being corroded by water and oxygen and rusting. The active net 3 is installed on a relatively flat slope surface (a part with a length of 1 meter and a height of 0.5 meters where the local protrusion or depression does not exceed 10 centimeters) through the active net fixed anchor rod 4, and the anchoring depth is 30 cm , 10cm exposed, the support platform sandwich panel 5 is horizontally placed in the active net 3, one end is close to the slope, and an L-shaped greening platform is formed with the slope. The water accumulation dish 6 is horizontally placed on the greening platform. The longevity bag body 1 is composed of three longevity bag units, with built-in nutrient soil, laid in layers, which can provide nutrients for plant growth. The longevity bag units are tightly placed side by side in the water accumulation dish 6 and close to the rock wall. The placed longevity bag body 1 is wrapped with insulation cotton 7. On the one hand, it plays a certain insulation role for plant growth and reduces the loss of water in the nutrient soil. On the other hand, it can also maintain heat when the temperature is low, which is beneficial to protect the plant root system. There are four longevity bag fixing anchor rods 2, two on each side of the longevity bag body, and the steel strand 8 is used to connect the longevity bag fixing anchor rods 2, and the insulation cotton 7 is tightened and fixed in a Z shape.
