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...

[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...

Abstract

The invention belongs to the technical field of slope greening, and in particular relates to rapid greening protection slope for an oligotrophic soil slope as well as a construction method thereof. The existing slope protection technology has the defect that the stability is low because a vegetation root system and the oligotrophic soil slope form a whole body difficultly. According to the technical scheme of the invention, the rapid greening protection slope for the oligotrophic soil slope comprises a three-dimensional geonet, nutritional soil columns, spiral steel piles and a base material layer; the nutritional soil columns and the spiral steel piles are arranged in soil below the three-dimensional geonet in a drilling way; the base material layer is arranged on the three-dimensional geonet; and the base material layer comprises a nutritional soil layer and a grass seed layer. The spiral steel piles are blade type spiral steel piles. The nutritional soil columns and the base material layer provide nutrition for the growth of vegetations on the oligotrophic soil slope and can promote rapid development of the slope vegetation root system. After the vegetations grow up, the root system, the vegetations, the three-dimensional geonet, the spiral steel piles and the slope form a whole body. The rapid greening protection slope for the oligotrophic soil slope is suitable for greening and slope protection under the oligotrophic soil environment.

Description

technical field [0001] The invention belongs to the technical field of slope greening, and in particular relates to a rapid greening slope protection for barren soil slopes and a construction method thereof. Background technique [0002] With the expansion and improvement of the transportation network, there will be situations where high-speed railways or expressways pass through barren land areas. For barren soil areas, it is difficult for vegetation to grow. In order to ensure the growth of vegetation, the existing greening technology constructs a certain thickness of humus soil layer on the slope. Similar greening technologies have the problem of long time for the roots of the vegetation to penetrate into the slope, and the workload of later maintenance. At the same time, because the root system of the vegetation layer is mainly in the humus layer, it cannot form a whole with the existing slope, and the stability is poor. Therefore, there is an urgent need for a rapid gr...
