Embodiment Construction
[0032] The present invention will be described in detail below in conjunction with the accompanying drawings, so that those of ordinary skill in the art can implement it after referring to this specification.
[0033] Such as Figure 1-6 Shown, a kind of subgrade earthwork reinforcement method of expressway engineering, comprises the following steps:
[0034] Step 1: First lay the earth-rock mixed material evenly on the upper end of the subgrade platform. After the earth-rock laying is completed, cover the upper end of the laid earth-rock with clay, and then continue to lay the clay on both sides of the earth-rock laying position to form a reinforced earth-rock oblique wave structure;
[0035] Step 2: Use an accurate angle measuring instrument to form the ramp angle of the clay pavement into a 45-degree bevel, then pour concrete at the beginning and end of the ramp structure, and then install the grounding laterally on the outside of the ramp Pile, pre-excavate the pre-burie...
