Road reconstruction excavated slope reinforcing structure and method

Abstract

The invention relates to the technical field of road reinforcement, in particular to a road reconstruction excavated slope reinforcing structure. The road reconstruction excavated slope reinforcing structure comprises an original slope protection structure, an expanded slope protection structure and a reinforcing structure connected with the original slope protection structure and the expanded slope protection structure. The original slope protection structure is arranged under an expanded road surface and buried. The expanded slope protection structure comprises a gabion belt arranged in thedirection of the road, and the gabion belt is arranged upwards in a step shape in multiple layers along the slope face of slope protection. The reinforcing structure comprises a connection net. One side of the connection net is connected to the inner side of the original slope protection structure, and the other side of the connection net is connected to the outer side of the gabion belt. A fill sandstone layer is arranged between the original slope protection structure and the expanded slope protection structure. By means of the road reconstruction excavated slope reinforcement structure andmethod, the slope protection structure has high slope protection capacity and strength, the slope protection width can be reduced, and the occupied area of the expanded road is reduced.

Description

technical field [0001] The invention relates to the technical field of road reinforcement, in particular to a road reconstruction digging slope reinforcement structure and a reinforcement method. Background technique [0002] Expressways belong to high-grade highways, and expressways refer to "highways that can adapt to the annual average day and night passenger car traffic volume of more than 25,000 vehicles, are exclusively used for high-speed driving in separate lanes, and all access and exit are controlled." Although countries have different names for expressways, they all refer to highways with more than four lanes (including), two-way separation, complete control of entrances and exits, and all interchanges. [0003] When designing the road, the road width will be designed with reference to the expected traffic volume in the area. However, with the development of the local economy, the popularity of private vehicles and the increasing number of freight vehicles, the or...

Problems solved by technology

[0003] When designing the road, the road width will be designed with reference to the expected traffic volume in the area. However, with the development of the local economy, the popularity of private vehicles and the increasing number of freight vehicles, the originally designed road width can no longer meet the traffic demand of the area. The road needs to be expanded

In the plain area, the road surface of the expressway is relatively high. The expansion of the expressway will not only extend the roadbed to both sides, but also extend the side slope to both sides. The overall width of the expressway will increase, which will also lead to an increase in the area occupied by the road. , will occupy more agricultural land or forestry land on both sides of the road, which will lead to an increase in economic cost and time cost
