Problems solved by technology

However, a survey in July 2008 found that because the reinforcement depth of plant roots sprayed with foreign soil is best in the range of 0.2-0.3m, new spalling has occurred
[0009] 3. Geocell, this method has a better effect on treating the peeling of the surface and middle layers of loess slopes, but the effect on thick layer peeling is not ideal, and the cost is higher

Embodiment Construction

[0035] Such as figure 1 Shown, the method for treating loess slope spalling disease of the present invention, comprises the following steps:

[0036] Step 1. Select the grass species and determine the density and structural size of the planting holes on the loess slope to be treated according to the conventional hole method, and then determine the number of seedlings required. The selected grass species is suitable for the geographical environment of the construction road section. Grass species that grow and have well-developed root systems, and the loess slope to be treated is the loess slope that will have peeling of the surface crust or peeling of the middle layer as determined by geological survey. In addition, it should be noted that it is also necessary to check whether there are ditches at the top of the slope to be treated and whether the ditches are blocked to ensure that the ditches at the top of the slope are unobstructed to prevent direct erosion of the slope by ra...

Abstract

The invention discloses a method of processing peeling disease of loess slope, comprising the steps of: selecting seeds and determining the density and structure size of the planting holes required to be planted on the loess slope to be processed; raising seedings: preparing nutrient soil, mixing the nutrient soil evenly, compacting and placing tightly for 2-4 days in a seeding container and seeding and raising the seeds till the length of the root system of the young seedlings is 2-4 mm; processing planting cellar holes on the loess slope, to be processed; hill spacing; transplanting the young seedlings with the nutrient soil to the planted cellar hole; covering a metal net on the loess slope to be processed of the seeds; laying a non-woven fabrics on the metal net; performing routine care on the herb. The invention is simple in operation, low in cost and good in harnesing process, which effectively solves the problems of disease peeling of a surface layer and a middle layer.

Description

technical field [0001] The invention relates to the technical field of slope engineering, in particular to a method for treating loess slope spalling disease. Background technique [0002] In reality, the spalling diseases of loess slopes can be divided into three categories according to the thickness of spalled layers: surface crust peeling, middle layer spalling and thick layer slumping spalling. [0003] Among them, the main characteristics of the exfoliation of the surface crust are: the thickness is generally between 3-5cm, and the exfoliation crust is in the form of flakes, nearly round, and trapezoidal, which often occurs in old loess. Caused by erosion and other reasons. [0004] The main characteristics of the middle layer exfoliation are: the thickness of the middle layer exfoliation is 10-40cm, the appearance of the exfoliation is generally arc-shaped or rectangular, and the scale is generally (1.0-1.5m)×(2.0-4.0m); Wedge-shaped, thicker at the top and thinner a...
