[0002] The core role of paving the grid during the construction of the reinforced earth retaining wall is to improve the structural stability through the interaction of the geosynthetic material and the fill; after the grid is laid horizontally, its high tensile property can effectively disperse the lateral pressure of the soil body and convert the local stress into overall stress; the frictional engagement of the grid and the soil particles forms a composite body, which significantly enhances the shear strength and prevents the deformation of the soil body.

[0003] Currently, there are still the following problems in paving the grid during the construction of the reinforced earth retaining wall: 1. Generally, there is a lack of corresponding grid paving tools, which makes the paving of the grid inconvenient and reduces the paving efficiency of the grid; 2. It is inconvenient for the staff to tighten the paved grid, which causes the paved grid to be prone to loosening; 3. When the paved grid is tightened, the already tightened grid cannot be automatically fixed, which affects the paving quality of the grid. SUMMARY
