Method for treating slope slide through modified reinforcement soil blind grids

Abstract

The invention provides an effective measure for radically curing landslides of road cutting side slopes. The method is to excavate grid trenches vertically and horizontally on the slope that has slipped or is likely to slide, and lay wooden piles at a certain interval at the bottom of the trench. Then fill the modified reinforced soil in the ditch, and form the modified reinforced soil blind grid after full compaction. The preparation of the modified reinforced soil is: first, the original soil is blended into lime soil according to a certain amount of ash, and then sprayed with an aqueous solution of expansive soil ecological modifier according to a certain proportion. Relevant dimensions of modified reinforced soil blind fence design must be calculated by slope stability. After the construction of the modified reinforced soil blind grid is completed, the slope soil modification construction is carried out according to the method of modifying the expansive soil with the expansive soil ecological modifier. The modified reinforced soil blind grid grid is connected with the modified soil on the slope to form a whole, which enhances the anti-sliding ability of the slope soil. The invention is suitable for controlling and protecting side slopes caused by special soils such as expansive soil in roads, railways, water conservancy, industrial and civil construction and other projects, as well as water and soil loss.

Description

technical field [0001] The invention relates to side slope protection engineering, and relates to a method for controlling side slope landslides. Background technique [0002] With the rapid development of highways and railways in my country, water damage and landslides have occurred in different degrees on the cutting slopes of highways that have been opened to traffic. For example, the Xiangshi Expressway in Hubei Province was completed and opened to traffic in 2003. After a rainy season, severe landslides, longitudinal cracks and landslides occurred on the expansive soil cutting slopes of stake numbers K6+780-K378+800. There have been as many as ten landslides. According to observations, the slope soil is loose and full of cracks. The crack width is about 1-2 cm and the depth is about 30-50 cm. There is a tendency of serious landslides, which seriously threatens the smooth flow and safety of the road. A similar situation also occurred on th...

AI Technical Summary

Problems solved by technology

Therefore, traditional slope protection schemes such as slope slowing down, mortar block stones, concrete blocks and other traditional protection methods are not useful due to limited conditions

Usually the landslide disposal method is to take an emergency measure to remove the collapsed earthwork, this method cannot fundamentally solve the problem

Irregular soil pits left after clearing cannot meet the requirements for smooth and beautiful slopes

At the same time, it also causes rainwater retention, which further aggravates the occurrence of landslides.

[0004] According to the data, there is no effective way to control the landslides of the expressways that have been opened to traffic.
