Description

Technical Field

[0001] The utility model relates to the field of river channel reinforcement, in particular to a river channel slope reinforcement structure used for overpass bridges. Background Art

[0002] In the fields of road, water conservancy, construction, etc., ordinary soil slopes are often ensured by slope reduction, support or a combination of the two. Soil slopes exist in large numbers in road projects, especially on both sides of rivers. During the construction of excavated soil slopes, the influence of rainfall and slope toe stress must be considered, so reinforcement measures are usually required.

[0003] However, the prior art has the following defects:

[0004] However, existing slope reinforcement structures usually use anchor rods to fix the fixed structure on the slope. The anchor rods are easy to loosen, causing the fixed structure to slip, resulting in the problem of slope sliding and collapse. In addition, the sliding and collapse of the river slope with an overpass can cause the bridge to collapse and be damaged, posing a great safety hazard. Utility Model Content
