Problems solved by technology
[0003] The prerequisite for ecological regreening technology is the overall stability of the slope. However, in the existing loess slope treatment methods, there are often such problems: the particles of the loess body are loose, and due to rainfall, the pore water pressure of the soil body in the slope increases and the cohesion decreases. The shear strength is reduced, and at the same time, collapsible deformation may occur, which is very unfavorable to the overall stability of the loess slope
Different schemes are adopted for different regions, rock and soil bodies, and slope slopes, but these technical schemes focus on planting and construction, and do not fully and fully utilize the characteristics of the loess slope itself, ignoring the loess slope itself Ability to discharge water and maintain water and soil balance system

Embodiment Construction
[0023] Such as figure 1 , figure 2 and image 3 Shown, a kind of water transfer and ecological management method of loess slope of the present invention, carry out according to the following steps:
[0024] Step 1. First, excavate and replace the soil at the top of the slope, and use sand, gravel or coarse sand to make the water seepage layer 1. The inclination angle of the bottom surface of the water seepage layer 1 is 8°-12°, and the thickness of the water seepage layer 1 is 27cm-33cm . The function of the water seepage layer 1 is to facilitate the flow of a part of water infiltrated from the top of the slope to the side slope surface through the water seepage layer 1 . Then fill the water blocking layer 2 on the water seepage layer 1, the water blocking layer 2 is compacted from plain soil, and the thickness of the water blocking layer 2 is 27cm-33cm. The soil and water conservation layer 3 is covered on the water blocking layer 2. The soil and water conservation layer...

The invention discloses a moisture transfer and ecological management method for a loess slope. The moisture transfer and ecological management method includes steps of excavating, changing and filling and making a water seepage layer at the top of the slope; filling a water stopping layer on the water seepage layer; covering a water and soil conservation layer on the water stopping layer; uniformly drilling holes on a surface of the slope below the water seepage layer at intervals, burying moisture transfer tubes in the holes, and arranging a gridding reinforced concrete framework along the surface of the slope; and further arranging a plurality of soil layer anchor rods on the slope. One end of each soil layer anchor rod is connected with the reinforced concrete framework while the other end of the soil layer anchor rod is anchored in a soil layer in the slope. Plants are planted in grids of the reinforced concrete framework. The moisture transfer and ecological management method for the loess slope has the advantages that integral stability of the loess slope is good, and ecologically sustainable development is realized.
Description
technical field [0001] The invention belongs to the technical field of slope stability and control, and in particular relates to a water transfer and ecological control method for loess slopes. Background technique [0002] The construction of infrastructure such as roads, railways, and water conservancy in loess areas inevitably forms a large number of exposed slopes. On the one hand, it affects the ecological environment. On the other hand, once it rains, it will cause serious soil erosion and even geological disasters such as landslides. In response to this situation, ecological protection and treatment technologies are often used to improve slope stability and protect the ecological environment at the same time. The technology of slope ecological protection and management is based on certain engineering and construction techniques. On the basis of first ensuring the overall stability of the slope, a certain thickness of nutrient soil layer that is conducive to plant grow...
