Abutment back for preventing high-fill subgrade bridge abutment traffic jump
The invention discloses an abutment back for preventing high-fill subgrade bridge abutment traffic jump. The abutment back is located between a bridge abutment and subgrade and sequentially comprises a supporting plate, a compacting layer, a buffer layer and a fixing layer from bottom to top. The compacting layer is located between the supporting plate and the buffer layer. The buffer layer is located between the compacting layer and the fixing layer. The supporting plate, the compacting layer, the buffer layer and the fixing layer are tightly fixed through longitudinal rebars. The abutment back is further provided with four drainage pipes. The abutment back has the advantages that the abutment back is simple in structure, through effective matching of the supporting plate, the compacting layer, the buffer layer and the fixing layer, the uneven settling phenomenon can be relieved effectively, and the partial breakage phenomenon of the subgrade, the abutment back and the bridge abutment is reduced; the two sides of the abutment back are additionally provided with side wings to form a trapezoidal structure, so that the whole strength, stability and stress tolerance of the abutment back are improved effectively, and the phenomenon of bridge abutment traffic jump is reduced effectively.
