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 existing expansive soil slopes with less vegetation in the rainy season, the present invention provides a soil layer anchoring structure for ecological protection of expansive soil slopes and its use. method, by digging conical holes on the expansive soil slope and setting anchor structures in each conical hole, the anchor structure can anchor and improve the soil near the conical holes to form anchor nodes to prevent shallow For layered landslides, plants with developed root systems are planted in the anchorage structure, and their roots are used to prevent soil erosion, thereby protecting the ecological environment and system of expansive soil slopes

Embodiment 1

[0032] Such as figure 1 and 2As shown, a soil layer anchoring structure for ecological protection of expansive soil slope, the anchoring structure is set in the pre-dug tapered hole on the slope of expansive soil slope, including two symmetrically arranged arc-shaped anchoring bases 1 and Two fixed anchoring rods 5, wherein the two arc-shaped anchoring bases 1 are on the same conical contour, thereby forming a planting cavity 2 for planting plants with developed root systems between them, distributed on the surface of the two arc-shaped anchoring bases 1 There are holes 102 for plant roots to pass through; there is no contact between the two side edges of the two arc-shaped anchoring bases 1, thereby forming two stress buffer zones 3, and the two side edges of each arc-shaped anchoring base 1 are along its generatrix There are arc-shaped support pieces 4 distributed in the length direction, and there is a gap between two adjacent support pieces 4 on the same side, and the sup...

Embodiment 2

[0043] This embodiment is an improvement made on the basis of embodiment 1, and its main structure is the same as that of embodiment 1. The shaped anchoring base 1 is on the same conical contour.

Embodiment 3

[0045] This embodiment is another improvement made on the basis of embodiment 1. Its main structure is the same as that of embodiment 1. The improvement is that: the two arc-shaped anchoring bases 1 are located in the conical contour, the The apex angle of the cone is 20-40°; the height of the two arc-shaped anchoring bases 1 is 30-80cm.

[0046] Of course, this embodiment can also be improved on the basis of Embodiment 2, and the improvement content is the same.

Abstract

A soil layer anchoring structure for ecological protection of expansive soil slopes and its use method. The anchoring structure is arranged in a pre-dug conical hole on the slope of expansive soil slopes, including two symmetrically arranged arc-shaped anchoring bases and two Fix the anchor rod, the planting cavity for planting plants with developed root system is formed between the two arc-shaped anchor bases, and there is no contact between the edges on both sides to form a stress buffer zone; the two fixed anchor rods are distributed in a cross, and the upper end of each fixed anchor rod An arc-shaped anchoring base is passed through, and the lower end passes through the planting cavity and another arc-shaped anchoring base in sequence, and then inserted into the soil on the side wall of the tapered hole. The present invention digs conical holes on the expansive soil slope, and sets an anchoring structure in each conical hole. The anchoring structure can anchor and improve the soil near the conical hole to form an anchoring node, preventing shallow For layered landslides, plants with developed root systems are planted in the anchorage structure, and their roots are used to prevent soil erosion.

Description

technical field [0001] The invention relates to the field of ecological environment management and protection, in particular to a soil layer anchoring structure for ecological protection of expansive soil slopes and a use method. 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 ...
