The utility model relates to the technical field of expressways, in particular to an expressway roadbed structure capable of preventing roadbed
softening, which comprises a roadbed layer, the top end of the roadbed layer is fixedly connected with a connecting
pipe, the top end of the connecting
pipe is fixedly connected with a rectangular ring, the bottom end of the connecting
pipe is fixedly connected with a drainage pipe, and the outer surface of the connecting pipe is provided with a plurality of slotted holes. Through the arrangement of the connecting pipe, the rectangular ring, the drainage pipe and the water absorption stone, during use, the rectangular ring is fixed to the top end of the connecting pipe, and the interior of the rectangular ring is arranged in a big-end-up mode, so that water on the
road surface can be collected and drained conveniently; the drainage pipe is used for draining rainwater collected by the connecting pipe and can guide a
route to be drained outwards, finally, through installation of the water absorption stone, the water absorption stone can absorb internal
water vapor, internal
moisture is prevented from forming a
water source and causing the internal structure to be soft, the pavement can be prevented from being soft and deformed after the water is drained, and therefore the effect of preventing the roadbed from being softened is achieved.
