Problems solved by technology

[0004] In order to solve the ecological damage problems such as water and soil loss and even shallow landslides caused by the erosion of the expansive soil slope with less vegetation in the rainy season, the present invention provides an ecological protection method for the expansive soil slope. Drilling and excavating tapered holes, and then filling the boreholes with collapsible loess and construction waste to form a modified anchor column for the improvement of the surrounding expansive soil. At the same time, an anchoring structure is set in each tapered hole to anchor The structure can anchor and improve the soil near the tapered hole to form an anchor node to prevent shallow landslides. Plants with well-developed root systems are planted in the anchor structure, and their roots are used to prevent soil erosion, thereby protecting expansive soil slopes. The role of ecological environment and system

Embodiment 1

[0043] Such as Figure 1-3 As shown, a method for ecological protection of expansive soil slopes, a number of modified anchor columns 2 and a number of plant planting anchor units 3 are distributed on the slope surface 1 of the expansive soil slope, wherein the plant planting anchor units 3 are planted with root systems Developed plants use their roots to anchor and protect the soil of the expansive soil slope. The modified anchor column 2 includes an anchor pipe 201 arranged in a borehole on the slope surface 1. The upper and lower ends of the anchor pipe 201 are open, and the surface of the anchor pipe 201 is Penetration holes with a diameter of 2 mm are densely covered, and the anchor pipe 201 is filled with collapsible loess, thereby forming a loess area 203 in the anchor pipe 201, and the upper part of the loess area 203 in the anchor pipe 201 is filled with construction waste formed. Garbage filter layer 204 , the top of the construction waste filter layer 204 is flush w...

Embodiment 2

[0047] This embodiment is an improvement made on the basis of embodiment 1. Its main structure is the same as that of embodiment 1. The improvement is that the construction waste filter layer 204 is filled with crushed construction waste. It is formed in the anchor pipe 201, and is divided into upper layer, middle layer and lower layer from top to bottom, wherein, the thickness of the upper layer is 20cm, which is made of large particles of construction waste with a particle size of 35-55mm; the thickness of the middle layer is 14cm, It is paved with medium-grained construction waste with a particle size of 20-40mm; the thickness of the lower layer is 6cm, and it is paved with fine-grained construction waste with a particle size of no more than 10mm.

Embodiment 3

[0049] This embodiment is another improvement made on the basis of embodiment 1, its main structure is the same as that of embodiment 1, and the improvements are as follows: image 3 As shown, the center of the anchor pipe 201 is provided with a steel anchor rod 202. The bottom end of the steel anchor rod 202 exceeds the bottom of the anchor pipe 201 and is inserted into the expansive soil slope, and the top end protrudes from the top of the anchor pipe 201.

[0050] In this embodiment, the bottom end of the steel anchor rod 202 is generally 20-50 cm beyond the bottom of the anchor pipe 201, and the top end is 10 cm beyond the top.

Abstract

An ecological protection method for expansive soil slopes. Several modified anchor columns and several plant planting anchor units are distributed on the slope surface of expansive soil slopes. Plants with developed root systems are planted in the plant plant anchor units. The modified anchor columns include densely covered The anchor pipe with a diameter of 2mm permeable hole is filled with collapsible loess and construction waste filter layer from bottom to top in the anchor pipe. The present invention drills and excavates conical holes on the expansive soil slope, and then fills the boreholes with collapsible loess and construction waste to form a modified anchor column for the improvement of the surrounding expansive soil. An anchoring structure is set in the shaped hole. The anchoring structure can anchor and improve the soil near the tapered hole to form an anchoring node to prevent shallow landslides. Plant a plant with a well-developed root system in the anchoring structure and use its root system to prevent soil erosion. , thus playing a role in protecting the ecological environment and system of expansive soil slopes.

Description

technical field [0001] The invention relates to the field of ecological environment management and protection, in particular to a method for ecological protection of expansive soil slopes. Background technique [0002] Expansive soils are widely distributed in my country, such as Guangxi, Yunnan, Henan, Hubei, Sichuan, Shaanxi, Hebei, Anhui, Jiangsu and other places. Water immersion bearing capacity attenuation, drying shrinkage crack development and other characteristics. [0003] In the hilly areas with less precipitation in my country, such as the western and southern regions of Henan, the overall precipitation is less throughout the year, and it is mostly concentrated in summer and autumn. The gentle slope vegetation composed of expansive soil is already very fragile. Loss, even shallow landslides of topsoil, eventually lead to the complete destruction of ecological vegetation on expansive soil slopes. Contents of the invention [0004] In order to solve the ecological...
