The utility model discloses a highway
subgrade settlement control structure, and belongs to the technical field of
subgrade engineering, the highway
subgrade settlement control structure comprises a subgrade layer, the subgrade layer comprises a filler bottom layer, a filler middle layer is laid at the top end of the filler bottom layer, a filler
surface layer is laid at the top end of the filler middle layer, and a drainage mechanism is arranged in the filler middle layer and comprises a plurality of groups of transverse drainage pipes; the transverse drainage
pipe is fixedly installed at the top of the filler bottom layer, the top end of the transverse drainage
pipe is connected with a plurality of longitudinal drainage pipes, the longitudinal drainage pipes are fixedly installed in the filler middle layer, and a plurality of drainage
layers are arranged in the filler
surface layer and correspond to the longitudinal drainage pipes one to one; the drainage mechanism is simple in structure and good in drainage effect, the problems of roadbed
softening, settlement and the like caused by water accumulation are effectively avoided, meanwhile, the overall strength and stability of the roadbed layer are greatly enhanced through the pre-stressed anchor rods and the grid net, and the
traffic load capacity of the roadbed layer is improved.
