Because the plain soil tamped layer does not contain impurities basically and has high soil layer density, microorganisms and plants cannot survive in the soil layer, so that the action of the microorganisms or the damage of root systems of the plants to the plain soil tamped layer can be effectively avoided, and the plain soil tamped layer can be kept intact all the time and is not easy to collapse.

In this kind of roadbed structure, the base member plays the effect of skeleton, and for the roadbed of piling up by stone or earth completely, the roadbed that adopts the reinforced concrete base member resists the flood impact ability stronger.

The layer is tamped by the plain soil instead of stones, so that the exploitation amount of stones can be effectively reduced, and the damage to the environment is reduced.

Optionally, the earth's surface is provided with a groove, and the rubble layer is located in the groove.

Optionally, one end of the embedded column is bullet-shaped.

The embedded column is bullet-shaped so as to reduce the resistance applied when the embedded column is driven into the soil layer.

Optionally, the base is a reinforced concrete base, and the embedded column is a reinforced concrete embedded column.

Specifically, after the embedded column is driven into the soil layer, a matrix is poured on the basis of the embedded column.

Optionally, a sandstone layer is arranged above the base body, and the rammed vegetarian soil layer is located below the sandstone layer.

The gravel layer is used for supporting the asphalt pavement above, and the gravel layer is arranged above the base body and the plain soil tamping layer, so that accumulated water on the asphalt pavement above is conveniently discharged.

Optionally, the sand layer encloses a retainer ring, and the sand and stone layer is located in the retainer ring.

Optionally, the particle size of the sand in the sand layer is smaller than the particle size of the crushed stone in the crushed stone layer.

Optionally, the thickness of the gravel layer is smaller than that of the gravel layer.

The utility model has the beneficial effects that: the isosceles trapezoid-shaped base body, the plain soil compaction layer and the sand layer form a dam-like structure, the dam-like structure can effectively resist flood impact, and the base body, the plain soil compaction layer and the sand layer are not easily washed down by flood.
