Pre-buried pipeline suitable for pavement shallow layers
The invention relates to a pre-buried pipeline suitable for pavement shallow layers. The pre-buried pipeline comprises a pavement pre-buried groove, wherein a foundation layer is arranged in the pavement pre-buried groove. The pre-buried pipeline is characterized in that a pipeline strengthening assembly is arranged on the foundation layer; supporting channels are distributed in the pipeline strengthening assembly; auxiliary supporting rods are arranged in each of the supporting channels; besides, partition assemblies are distributed at the periphery of each of the supporting channels; a filling layer is arranged between the partition assemblies and the periphery of each of the supporting channels; a back-filling layer is distributed in the pavement pre-buried groove, and a blocking layer is distributed on the back-filling layer. Therefore, the laying requirement of multiple pipelines is met, and besides, the pre-buried pipeline can effectively bear external stress, so that an internal pipeline can be protected from being stricken, and underground water can be prevented from permeating into the pipeline and eroding the pipeline; in addition, the pipeline can bear downward longitudinal stress from the ground, so that the longitudinal extrusion for a subsequent pipeline is avoided.
