Embodiment 1
[0026] This embodiment provides an efficient layered backfill construction method for earth and rock, including the following steps:
[0027] (1) Substrate treatment: Before construction, the surveyors will release the dividing line according to the design drawings, and remove the vegetation and construction waste on the surface. For local areas with unfavorable geological conditions, their specific positions must be determined and marked according to the design drawings and on-site survey;
[0028] (2) Filling in layers: fill in layers according to the full width of the section in the bottom soil treatment, fill from the lowest point, and the thickness of loose paving before filling is not more than 25cm and not less than 12cm;
[0029] (3) Paving and leveling: the earth and rocks are transported from the excavation area to the filling area by dump truck, and the unloaded soil is leveled by the bulldozer;
[0030] (4) Watering and drying: According to the water content of the...
