Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of slope treatment, specifically to a retaining wall structure for slope treatment. BACKGROUND

[0002] Slope refers to the slope surface with a certain slope made on both sides of the roadbed to ensure the stability of the roadbed. Retaining wall refers to the structure supporting the roadbed fill or the soil body of the hillside to prevent the deformation and instability of the fill or the soil body. In the cross section of the retaining wall, the part in direct contact with the supported soil body is called the wall back; the part opposite to the wall back and in the air is called the wall surface; the part in direct contact with the foundation is called the base; the top surface of the wall opposite to the base is called the wall top; the front end of the base is called the wall toe; and the rear end of the base is called the wall heel.

[0003] According to the utility model CN221218883U, a frost heaving prevention and drainage retaining wall for a water-rich slope, a layer of gravel is arranged on the outer side of the wall back side of the retaining wall body, the lower side of the bottom, and the outer side of the part below the slope bottom ground. The arrangement of the gravel layer allows the underground water on the wall back side of the retaining wall to pass through the retaining wall from below to the front of the wall surface side and be discharged outside before the underground water freezes in winter, effectively reducing the water accumulation on the wall back side of the retaining wall. When the soil body freezes in winter, the frost heaving effect of the soil body adjacent to the side of the retaining wall can be greatly inhibited due to the presence of the gravel layer, the harm of soil frost heaving to the wall body is avoided to the greatest extent, the structural stability is better, and the reliability is higher.

[0004] However, the existing slope retaining wall is provided with various drainage holes and drainage pipes on the wall body to facilitate the penetration and outflow of rainwater, or uses the gravel in the above-mentioned comparative document for penetration. Although the above-mentioned measures ensure the rainwater penetration, the strength of the wall body is greatly affected, so a new retaining wall structure is proposed to combine with the slope treatment.
