Embodiment 1
[0036] A rapid greening slope protection for barren soil slopes, including a three-dimensional geonet, a nutrient soil column 1, a spiral steel pile 2 and a base material layer 3, and the nutrient soil column 1 and the spiral steel pile 2 are drilled under the three-dimensional geonet In the soil, the substrate layer 3 is set on the three-dimensional geonet. The three-dimensional geonet is connected to the spiral steel pile 2 by hooking, and the joint is protected by a concrete pile head, and the three-dimensional geonet is embedded in the lower part of the concrete pile head. The spiral steel pile 2 is a blade-type spiral steel pile. The outer diameter of the spiral steel pile 2 is 50mm, the wall thickness is 0.1 times of the outer diameter, and the blade diameter is 2.5 times of the outer diameter. The surface of the spiral steel pile 2 has a zinc coating. The nutrient soil columns 1 are evenly distributed in the form of vertical and horizontal rows, the distance between th...
Embodiment 2
[0039]A rapid greening slope protection for barren soil slopes, including a three-dimensional geonet, a nutrient soil column 1, a spiral steel pile 2 and a base material layer 3, and the nutrient soil column 1 and the spiral steel pile 2 are drilled under the three-dimensional geonet In the soil, the substrate layer 3 is set on the three-dimensional geonet. The three-dimensional geonet is connected to the spiral steel pile 2 by hooking, and the joint is protected by a concrete pile head, and the three-dimensional geonet is embedded in the lower part of the concrete pile head. The spiral steel pile 2 is a blade-type spiral steel pile. The outer diameter of the spiral steel pile 2 is 80mm, the wall thickness is 0.1 times of the outer diameter, and the blade diameter is 3.0 times of the outer diameter. The surface of the spiral steel pile 2 has a zinc coating. The nutrient soil columns 1 are evenly distributed in the form of vertical and horizontal rows, the distance between the...
Embodiment 1 and Embodiment 2
[0041] Both embodiment 1 and embodiment 2 are constructed by the following method:
[0042] [1] Carry out geological survey to determine the setting depth of the nutrient soil column 1, and the setting of the depth of the nutrient soil column 1 needs to be able to provide water and nutrients that can satisfy the survival of the grown vegetation;
[0043] [2] Clean up the slope to make the surface of the slope smooth, so as to facilitate the subsequent laying of the three-dimensional geonet and the construction of the substrate layer 3;
[0044] [3] The spiral steel pile 2 is drilled. When the slope has a potential sliding surface, the spiral steel pile 2 needs to pass through the potential sliding surface;
[0045] [4] Nutrient soil column 1 is drilled;
[0046] [5] Use the three-dimensional geonet to lay the entire surface of the slope, and connect the spiral steel pile 2 with the three-dimensional geonet;
[0047] [6] Carry out base material layer 3 construction, use the m...
