Embodiment Construction
[0008] Below in conjunction with accompanying drawing and specific construction method, the present invention will be further described.
[0009] see figure 1 , carry out construction according to the following steps:
[0010] (1) After the embankment is filled to the top of the designed next-level embankment slope 11, when the new filling starts to the design wrapping width at the bottom of the embankment slope of this level (the wrapping width is not less than 4 m), the embankment wrapping In the border area, sprinkle the spare soil material to a soft and plastic state, and evenly sprinkle the cement on the watered soil material according to the weight ratio of cement to wet soil at a ratio of 8%, and use an excavator to carry out road mixing construction, and the road mixing is completed. The cement-modified soil is in a hard plastic state;
[0011] (2) Lay the road-mixed cement-modified soil on the bottom of the embankment slope excavation area at this level. The virtual...
