[0017] like Figure 1-4The construction process of this application is: base cleaning → laying out → cushion pouring → foundation masonry → stone stacking → bamboo reinforcement anchoring → hanging wire mesh 4 → surface covering with soil → compacting and maintenance.
[0018] The specific construction process is as follows:
[0019] 1) Base treatment: The original soil in this project area is relatively loose and has a high sand content. The loose base soil in the test area is cleaned to a hard base, and the floating dust on the surface is removed with a brush. According to the actual situation, the base is irregular in shape after cleaning.
[0020] 2) Laying out the lines: Laying out the lines along the bottom of the original trench wall and taking soil to the hard base layer, with a height laying out slope of 3% to form a reinforcement area 7.
[0021] 3) Pouring of cushion layer: The wet water of reinforcement area 7 is used to lay the mortar layer, and the natural stone is laid on the mortar layer with a width of 500mm.
[0022] 4) Foundation masonry: natural stone masonry height 300mm.
[0023] 5) Stone masonry: Natural stones are laid according to the shape of the site to form a retaining wall2.
