Method for improving stability of high soil slope

Abstract

The invention relates to a method for improving the stability of a high soil slope, in particular to a method for improving the high soil slope stability and being applied to the construction field. The method provided by the invention has the advantages that the excavation volume can be greatly reduced, the construction is convenient, the safety is high, the operation is simple, and the circumstance that the high soil slope is easily unstable in the working condition of a rainstorm or an earthquake can be effectively prevented. The method comprises the following steps: a, performing slope cutting treatment on a soil body, additionally arranging porous water drainage steel pipes, and stuffing water drainage hoses in the steel pipes; and b, additionally arranging a concrete retaining wall at the slope toe, pouring pure cement paste into a gabion or stone ballast till the pure cement paste overflows, and ensuring that the gabion or the stone ballast is formed as a hole. By adoption of the method provided by the invention, the upper part of the high soil slope is subjected to the proper slope cutting treatment; the concrete retaining wall and the reinforced gabion are additionally arranged; gaps are backfilled with the stone ballast; the excavation volume is low; the construction is convenient; the safety is high; the operation is simple; the treatment cost is low; the resistance of the slope toe can be increased; and the stability of the high soil slope can be remarkably improved.

Description

technical field [0001] The invention relates to a method for increasing the stability of a high-soil slope, in particular to a method for increasing the stability of a high-soil slope applied in the construction field. Background technique [0002] The high soil slope structure refers to the slope structure with a soil thickness greater than 25 meters. When the soil thickness is greater than 25 meters, its height is large, and there is a rock foundation in the lower part of the soil, which is prone to slope failure under heavy rain and earthquake conditions. When it is stable and has a major impact on buildings and engineering. In the existing technology, in order to ensure the stability of the soil slope with a large height, it is generally adopted to reduce the slope (generally slower than 1:2.5) or excavate a large number of slopes and increase slope support measures. method. But among several solutions in the prior art, it is unfavorable to project investment, has infl...

Problems solved by technology

However, among the several solutions in the prior art, they are unfavorable to project investment, affect the construction period, and are not conducive to construction.

Therefore, there is no one in the prior art that can greatly reduce the amount of excavation, is convenient for construction, has high safety, is simple to operate, and can effectively prevent the increase of soil quality that is prone to slope instability in high-soil slopes under heavy rain and earthquake conditions.
