Problems solved by technology

[0004] However, the side of the landslide already has a sliding tendency and is unstable. However, in the above treatment methods, the operation steps such as arranging pile positions, drilling grouting holes, and grouting are all carried out on the side of the landslide, and it is easy to cause landslides during the implementation process. This not only exacerbates the severity of the landslide, but is also detrimental to the personal safety of operators.

Embodiment Construction

[0036] The present invention will be described in further detail below in conjunction with accompanying drawing, and the words " front ", " rear ", " left ", " right ", " upper " and " lower " used in the following description refer to the direction in the accompanying drawing, word "Bottom" and "top", "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

[0037] Such as figure 1 As shown, in this embodiment, the location of the landslide 11 to be controlled occurs on one side of the side slope 1 and is located near the top of the side slope 1 .

[0038] The road slope landslide control method includes the following steps:

[0039] S1, such as figure 2 As shown, the protective net 2 is covered on the top surface of the landslide 11, and the edge of the protective net 2 extends to the side slope 1 where the landslide 11 does not appear and is fixed, so that the earth and rocks on the top surface of the la...

Abstract

The invention discloses a road slope landslide treatment method, and belongs to the technical field of landslide treatment. According to the key points of the technical scheme, the road slope landslide treatment method comprises the following steps that the top face of a landslide is covered with a protective net, and the edge of the protective net extends to the place at which no landslide occuron the slope and is fixed; a plurality of pile positions are arranged on the top surface of the protective net, and a plurality of pile columns used for connecting the protective net, the landslide and the interior of a slope are formed by grouting; grouting holes are drilled on the pile columns, the grouting holes penetrate through the pile columns to the side, on which no landslide occurs, of the slope, and grouting pipes are arranged in the grouting holes to form tension piles by grouting into the grouting pipes; and plant seeds are planted in meshes of the protective net, the stability ofthe landslide treatment process is improved, and the effect of the landslide treatment is improved.

Description

technical field [0001] The invention relates to the technical field of landslide treatment, in particular to a road side slope landslide treatment method. Background technique [0002] Landslide is the process and phenomenon in which the local stability of the slope is destroyed. Under the action of gravity, the rock mass or other debris slides downward along one or more fractured sliding surfaces as a whole, which brings hidden dangers to road safety. There are many factors that induce landslides. The geological structure and physical and mechanical properties of slope rock and soil are the internal factors that determine its stability. Rainfall, groundwater level changes, and human engineering activities are external factors that affect slope stability. The formation of landslides The process is often the result of the interaction of internal and external factors. [0003] Grouting to form piles connecting landslides and slopes is a commonly used landslide control method....
