Description

Technical Field

[0001] The utility model relates to the technical field of slope anti-slip, in particular to a slope anti-slip structure. Background Art

[0002] Landslide is a geological phenomenon in which the rock and soil of a slope slides along a continuous shear failure surface under the action of the slope top load and the slope's own weight. The mechanism of landslide is that the shear stress on a certain sliding surface exceeds the shear strength of the surface. In engineering, in order to reduce the hazards of landslides, protective structures are set up on the slope.

[0003] Slope anti-slip structures play a vital role in geological engineering and civil engineering. Their main function is to enhance the stability of the slope and prevent disasters such as slope sliding and collapse caused by various natural factors or human activities. By adopting structures such as anti-slip piles, anchor rods, retaining walls, etc., the anti-slip structure can effectively disperse the internal stress of the slope and improve the overall strength of the slope. In addition, the anti-slip structure can also reduce the scouring of the slope by rainwater, prevent soil erosion, and further protect the integrity of the slope. In practical applications, the slope anti-slip structure not only ensures the safety of infrastructure such as roads and bridges, but also maintains the safety of people's lives and property.

[0004] In conventional gravity retaining walls, the wall cross-section is large and consumes a lot of materials. If it is built on a soft foundation, it is often limited by the bearing capacity. The wall height should not be too high and the economic effect is not obvious. In view of this, we proposed a slope anti-slip structure. Utility Model Content
