Slope surface dissected valley greening scour preventing system and construction method thereof

Abstract

The invention provides a slope surface dissected valley greening scour preventing system and a construction method thereof. The slope surface dissected valley greening scour preventing system comprises a varying slope arranged on a ramp. The varying slope is internally provided with a water gathering area. The front end and the rear end of the water gathering area in the gradient direction from low to high are each provided with a row of sand intercepting shrubs. Saliz matsudana wood piles arranged in a polygon manner and twisted and connected through connecting fixing ropes are inserted in asoil body of the water gathering area. Nutrient bars embedded in the soil body are arranged at the centers of the saliz matsudana wood piles, and each nutrient bar is composed of an outer shell with the surface provided with fertilizer outlet holes and an inner cavity filled with ecological matrix fertilizer. According to the slope surface dissected valley greening scour preventing system and theconstruction method thereof, construction is convenient, the unit layout is reasonable, the excellent greening scour preventing capability is achieved, the ecological environment protection slope surface and dissected valley ecological environment recovering function is achieved, long-term usage can be achieved under the situation that manual intervention is not needed, benefits are durably brought into play, solving of the problem about the high sand content of the water source in the high-sand-content water source area is facilitated, and the slope surface dissected valley greening scour preventing system and the construction method thereof are suitable for varying slope, dissected valley and channel interior water and soil loss treatment.

Description

technical field [0001] The invention belongs to the technical field of water and soil conservation, and in particular relates to a slope cutting ditch greening anti-scouring system and a construction method thereof. Background technique [0002] At present, the downcutting of channel erosion in the Loess Plateau area of ​​my country is intense, and the downcutting of gully erosion on slopes and channels not only has a great impact on the instability of slopes and channels, but also causes serious water and soil loss on slopes and channels. The resulting high-sediment flow flows into the river, causing the sediment content in the river to increase. Slope cut ditch treatment is an important part of ditch treatment and ditch bed fixation. Through slope cut ditch treatment, the generation and confluence of slope cut gullies can be reduced, the downcutting at the bottom of the ditch can be prevented, and the erosion base point can be stabilized, thereby greatly reducing gully eros...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a slope cut ditch greening anti-scour system and its construction method for the above-mentioned deficiencies in the prior art. While having excellent greening anti-scour ability, it also has the function of restoring the ecological environment of slopes and gullies that are ecologically friendly. It can be used for a long time without manual intervention, and it will be beneficial for a long time, and it is beneficial to the sediment content of water sources in areas with high sand content. The weakening of the problem of height is suitable for the control of water and soil loss in variable slopes, cut ditches and ditches
