AI Technical Summary

⚠Technical Problem

In existing green prefabricated soil nailing wall slope protection surface layers, the reinforcement layer does not adhere tightly to the soil, resulting in poor structural stability, uneven stress distribution, and a tendency for local voids to occur, thus reducing the protection effect.

⚗Method used

The protective structure consists of a skin layer, a protective material layer, a honeycomb reinforcement layer, and a performance material layer. The honeycomb reinforcement layer has a serrated texture on the inner wall of the honeycomb pores to enhance the embedding-interlocking effect with the soil and improve the bonding strength and deformation resistance.

🎯Benefits of technology

It significantly improves the adhesion between the slope protection surface layer and the soil, evenly distributes soil pressure, enhances structural stability, prevents soil particle loss, and extends service life.

Abstract

The utility model relates to a kind of green assembly type soil nail wall slope protection surface layer structures in slope protection technical field, especially, including skin layer, protective material layer, honeycomb reinforced layer and performance material layer from bottom to top are sequentially arranged, the honeycomb reinforced layer's honeycomb hole inner wall is equipped with zigzag texture.The utility model is by setting honeycomb reinforced layer on the upper portion of protective material layer, the structure of honeycomb reinforced layer is compared with traditional square structure, compared with the contact area of soil body is increased by 30%-50%, porosity is reduced by 40%, the adhesion of slope protection surface layer and soil body is significantly improved;The mechanical distribution of honeycomb grid structure is more uniform, can effectively disperse soil body pressure, reduce local stress concentration, improve deformation resistance;Honeycomb hole inner wall and soil body form "embedded solid-bite" effect, enhance the bonding force of surface layer and soil body, prevent soil particle loss.
