Problems solved by technology

[0004] Aiming at the defects and problems existing in the existing ecological slope protection, the present invention provides a composite ecological slope protection with plant organic combination and its construction method. The ecological bag of the flora, the ecological slope protection can reduce the area of ​​the ecological bag affected by the water flow, prolong the service life of the ecological bag, and the ecological slope protection has the function of protecting the plant seeds, preventing the plant seeds from being taken away by the water flow, so that the plants are stable growth, and the ecological slope protection laying method is simple and convenient, with a wide range of applications, and requires low terrain conditions

Embodiment 1

[0025] River bank slope protection is an amphibious ecosystem between land and water. It is often affected by the fluctuation of water level. The erosion is particularly serious in the transitional stage of water and land. It has caused large-scale soil erosion for a long time, and it is more difficult for vegetation to take root. The ecosystem has been severely damaged. Especially in the middle and upper reaches of rivers with turbulent water flow and many deposited sand and pebbles, the plant seeds in the water level fluctuation zone are easily washed and lost by the water flow, so that the plants cannot survive in large areas, and the vegetation cannot be effectively artificially restored. The water that plays a key role in the ecosystem - The transition zone of land connection is destroyed and cannot exist stably for a long time.

[0026] Existing slope protection such as geocell slope protection has good greening effect, increased drainage performance, fast construction, ...

Embodiment 2

[0036] The present embodiment provides a kind of construction method of plant organic combination complex ecological slope protection, such as Figure 5 As shown, firstly, the river channel that needs to be laid with ecological slope protection is intercepted, and then based on the inclined bank slope 1 on both sides of the river channel, formwork 9 is laid at intervals along the inclined surface of bank slope 1, and the distance between every two adjacent formworks is 4m. A pouring area 10 is formed between the two formworks, and then according to the area of ​​the pouring area, the water-cement ratio is 1.0-1.4, and the amount of cement is 50kg-70kg / m 3 , The amount of fly ash is 60% to 70% of the amount of cement, and the cemented sand and gravel material with a porosity of not less than 15% is stirred. After the stirring is completed, it is poured from bottom to top in the pouring area and manually vibrated and leveled to form a gel. Sand and gravel layer 2, the laying met...

Abstract

The invention discloses a plant organic combination compound ecological protection slope and a construction method. The plant organic combination compound ecological protection slope comprises a gelatinized sand gravel layer which takes riverbed sand gravel, cement and coal ashes as main raw materials, the gelatinized sand gravel layer has a safe and stable structure and is high in high water flowwashing resistance; during laying, a formwork is used for carrying out pouring layer by layer from bottom to top, so that construction is convenient, requirements on a laying terrain are low, in addition, plants can take roots in the pore of the gelatinized sand gravel layer, and in addition, a complicated pore structure of the gelatinized sand gravel can prevent plant seeds from being taken awayby water flows. The invention provides the plant organic combination compound ecological protection slope and the construction method. The ecological protection slope has an obvious surface greeningeffect, has a safe and stable structure and is high in erosion resistibility. In addition, the ecological protection slope is provided with an ecological bag containing ETS (ecological treatment system) ecological florae, the ecological protection slope can reduce an area, which is impacted by water flows, of the ecological bag, and the service life of the ecological bag is prolonged. In addition,an ecological protection slope laying method is convenient and simple, has a wide applicable range and has a low requirement condition for terrains.

Description

technical field [0001] The invention belongs to the technical field of water conservancy engineering, and in particular relates to a compound ecological slope protection of an organic combination of plants and a construction method thereof. Background technique [0002] River bank slope protection is an amphibious ecosystem between land and water. It is often affected by the fluctuation of water level. The erosion is particularly serious in the transitional stage of water and land. It has caused large-scale soil erosion for a long time, and it is more difficult for vegetation to take root. The ecosystem has been severely damaged. Especially in the middle and upper reaches of rivers with turbulent water flow and many deposited sand and pebbles, the plant seeds in the water level fluctuation zone are easily washed and lost by the water flow, so that the plants cannot survive in large areas, and the vegetation cannot be effectively artificially restored. The water that plays a ...
