The stability of slopes is directly related to the safety of infrastructure and residential areas. Although traditional slope reinforcement technologies such as reinforced concrete retaining walls, soil nail walls, and slope protection piles have significant effects, they are costly, complex to construct, and have a significant impact on the environment. Therefore, it is of great significance to develop an economical, environmentally friendly, and efficient slope reinforcement technology. Utility Model Content

[0006] Preferably, a bamboo reinforcement fluidized soil pedestal is provided on the steel pull rod between the anchor and the bamboo reinforcement fluidized soil frame, the rear end of the bamboo reinforcement fluidized soil pedestal is vertically arranged, and the inclination angle of the front end of the bamboo reinforcement fluidized soil pedestal matches the inclination angle of the soil slope.

[0007] Preferably, the bamboo reinforcement fluidized solidified soil T-shaped support anchor plate is provided with a T-shaped support anchor plate bamboo reinforcement skeleton and is cast using fluidized solidified soil.

[0008] Preferably, the bamboo reinforcement skeleton of the T-shaped anchor plate is composed of a plurality of vertical bamboo longitudinal reinforcements and horizontal bamboo longitudinal reinforcements, L-shaped bamboo reinforcements are arranged between the vertical bamboo longitudinal reinforcements and the horizontal bamboo longitudinal reinforcements, and are tied with bamboo hoops and hemp ropes.

[0009] Preferably, the fluidized solidified soil is made by mixing loess, cement, fly ash and water.

[0010] Preferably, the bamboo reinforced fluidized soil frame is a grid-shaped structure composed of a number of bamboo reinforced fluidized soil beams and bamboo reinforced fluidized soil columns, and the squares formed between the bamboo reinforced fluidized soil beams and the bamboo reinforced fluidized soil columns are filled with vegetation soil, and green plants are planted in the vegetation soil.

[0011] Preferably, a steel pad is provided at the installation location of the nut and the bamboo reinforcement fluidized solidified soil T-shaped anchor plate.

[0012] After adopting the above structure, the beneficial effects of the utility model are:

[0013] This structure uses bamboo instead of steel bars and fluidized solidified soil instead of concrete, which greatly saves non-renewable resources, reduces costs, and reduces carbon emissions, which is highly consistent with the dual carbon strategy and green and low-carbon construction concepts.

[0014] Planting plants in the frame of this structure can not only beautify the environment and regulate the ecology, but also the roots of the plants can enhance the shear strength of the shallow layer of the slope to a certain extent.

[0015] This structure uses bamboo reinforced fluidized solidified soil frame prestressed T-shaped anchor plates to reinforce the soil fill slope in the early stage. After the fill slope consolidates and settles under the action of self-weight stress, it relies on the soil's own strength to maintain the stability of the slope. The bamboo reinforcement slowly decays and decomposes, and merges with the fluidized solidified soil and fill, which has a positive effect on the surrounding environment and ecology.
