Problems solved by technology

Due to the erosion of rainwater on the side slope of the expressway, the rock and soil strength of the side slope is reduced, resulting in a decrease in anti-sliding force, reducing the quality of side slope protection, and increasing maintenance costs in the later period
At the same time, a large amount of capital needs to be invested in the construction and protection of highways that need to be rebuilt and expanded, the structure is relatively complex, and the protection effect is poor

Abstract

The invention discloses a side slope protection system for a renovation and extension expressway, and belongs to the technical field of side slope protection. A side slope of the system is sequentially provided with geotechnical grid cloth, filling bags, a honeycomb frame, a rubble layer, a coconut net layer and a filler layer from the bottom layer to the top layer. The filling bags are stacked layer by layer along the gradient of the side slope and arranged on the geotechnical grid cloth, fixing rods are arranged between the filling bags and the side slope, anchor rods are arranged between the honeycomb frame and the filling bags, downward water leakage holes are formed in each honeycomb hole of the honeycomb frame, the honeycomb frame is filled with rubbles on the rubble layer, the filler layer comprises modified soil and plant seeds, and a drainage ditch is formed in the slope bottom of the side slope. The side slope protection system for the renovation and extension expressway is simple in structure and easy to construct, the construction cost can be reduced, the construction progress is quickened, rock weathering and water and soil loss of the side slope are effectively prevented, and the protection time is long.

Description

technical field [0001] The invention relates to the technical field of side slope protection, in particular to a side slope protection system for reconstruction and expansion of expressways. Background technique [0002] With the continuous increase of highway mileage in my country, people's demand for transportation is increasing, and the number of highways that need to be renovated and expanded is also increasing. The slope of the expressway is eroded by rainwater, which reduces the strength of the rock and soil of the slope, resulting in a decrease in the anti-sliding force, reducing the quality of the slope protection, and increasing the maintenance cost in the later period. At the same time, the construction and protection of the expressway that needs to be renovated and expanded requires a lot of investment, the structure is more complex, and the protection effect is poor. [0003] Therefore, it is of great practical value to design a slope protection system for the r...
