A greening and anti-scouring system for slope cutting ditch and its construction method

Abstract

The invention provides a slope cut ditch greening and anti-scour system and its construction method. The slope cut ditch greening and anti-scour system includes a slope change arranged on the slope, and a water collection area is set in the change slope. There is a row of sand-blocking shrubs at the front and back ends of the high slope direction. The soil in the catchment area is inserted into the soil body of the catchment area, which is arranged in a polygonal arrangement by connecting fixed ropes. The nutrition bar in the body is composed of a shell with fat outlet holes on the surface and an inner cavity filled with ecological matrix fertilizer. The invention has convenient construction, reasonable unit layout, excellent greening anti-scour ability, and ecological environment restoration function of slope and cut ditch. And it is beneficial to the weakening of the problem of high sediment content in water source areas with high sand content, and is suitable for the control of water and soil loss in variable slopes, cut ditches and ditches.

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...

AI Technical Summary

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
