Method for repairing geocells and side slopes

Abstract

The invention relates to a method for repairing geocells and side slopes. Each geocell comprises at least two bent earth stripes which stick to each other, wherein at least two rows of through holes are formed in the middle part of each soil stripe; joints of the soil stripes stick to one another to form a fixed hole perpendicular to the ground; an anchor rod nailed into the soil is arranged in the fixed hole; binding holes perpendicular to the soil stripes are formed in the soil stripes on two sides of the anchor rod; solder wires used for foxing the soil strips and the anchor are formed in the binding holes. By virtue of the geocells, root systems of plants can be effectively communicated with one another among the geocells; all independent geocells are combined to be a whole body by the root systems, so that a good reinforcing function is achieved; furthermore, the connection manner of the soil strips is changed, so that the geocells are fixed by the anchor rod; by virtue of the cooperation of the geocells and an improved construction method, the problem of side slopes formed due to soil wind erosion caused by insufficient vegetation coverage or dry grass periods can be solved.

Description

technical field [0001] The invention relates to the field of ecological restoration, in particular to a geocell and a slope restoration method, and is especially suitable for the restoration and protection of exposed slopes. Background technique [0002] In ecological restoration engineering, slope restoration is one of the most important fields, and among the methods of slope restoration, geocell restoration is a commonly used engineering method. However, there are still many problems in the existing geocells, such as: a geocell invented by the patent 200920178348.4, each cell is a single body, the plants can only grow in a single hole, and the water and nutrients between the cells cannot be effectively distributed. The movement of the geocell; and a kind of geocell invented by the patent 200920178350.1, there is a font air hole distributed on the ground strip.

However, there are still many problems in the existing geocells, such as: a geocell invented by the patent 200920178348.4, each cell is a single body, the plants can only grow in a single hole, and the water and nutrients between the cells cannot be effectively distributed. The movement of the geocell; and a kind of geocell invented by the patent 200920178350.1, there is a font air hole distributed on the ground strip. Located in the surface soil, the plant root system penetrates deep into the subsoil from the surface soil in the later stage, so the setting of the in-line ventilation hole still fails to solve the effective migration of water and nutrients between the plant root system and each compartment

In particular, there is no solution proposed for fixing the geocell and the slope, and the anchor rod is often fixed on one side of the ground strip, and then fixed and bundled with a drill wire. As a result, the ground strip is damaged and the installation process is cumbersome. It is not strong after a long time of use

[0003] Furthermore, when using geocells for slope protection, the common method is to fix the geocells on the slope, mix the plant seeds with the soil filled in the geocells, and then artificially cover the geocells with soil, but due to uneven sowing or The incomplete consistency of slope protection and greening will always show patchy phenomena on the slope and be exposed on the surface

Especially in the dry grass period in winter, the herbaceous plants are withered, the shrubs are deciduous, and the surface lacking vegetation coverage will easily lead to wind erosion of the surface soil, the outline of the geocell is exposed, and the human traces are large, which not only fails to achieve the slope protection effect, but also affects the ecological landscape.
