Embodiment Construction
[0019] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.
[0020] like Figure 1-2 As shown, a block stone layer slope protection subgrade with sunshade and ventilation and cooling functions is composed of embankment 1, block stone layer 2, geotextile 3, clay 4, and natural foundation 5. Fill the embankment 1 on the compacted natural foundation 5, the height of the embankment is 2.0-4.0m, the top width of the embankment 1 is 12.0m, the side slope of the embankment is 1:1.5, and the block stone layer 2 and the geotextile 3 are laid in turn on the side slope of the embankment and rammed clay 4; the particle size of the block stone layer 2 is controlled between 12-30cm, the horizontal thickness is 120cm, and the vertical thickness is 80cm, randomly thrown and squeezed to keep the slope smooth. In order to make full use of the different cooling effects of the open and clay-closed structures of the block ...
