Buried pipeline backfilling structure and construction method thereof
The buried pipeline backfilling structure comprises a pipe ditch and a pre-buried pipeline, the outer side of the side wall of the pipe ditch and the top of a pipe ditch cover plate are filled with pit slot soil layers, the lower portion of a pipe ditch bottom plate is filled with a pipe ditch cushion layer, and the lower portion of the pipe ditch cushion layer is filled with an undisturbed soil layer or backfill soil. A pipeline top soil layer is filled between the pipe ditch cover plate and the top of the pre-buried pipeline, a pipeline side upper soil layer is filled below the top of the pre-buried pipeline and above the height of a pipeline supporting angle of the pre-buried pipeline, and a pipeline side lower soil layer is filled below the height of the pipeline supporting angle of the pre-buried pipeline and above the bottom of the pre-buried pipeline; and a pipeline bottom soil layer is filled between the bottom of the pre-buried pipeline and the pipe ditch bottom plate. The method accords with the assumption of pipe-soil synergistic effect, is convenient to construct, ensures the backfilling quality of the soil layer, is convenient to overhaul in the use stage, reduces the excavation workload, shortens the operation time, reduces the interference to the surrounding environment, and achieves the goals of rapidness and safety.
本发明公开了一种埋地管道回填结构及其施工方法，包括：管沟和预埋管道，管沟侧壁外侧及管沟盖板顶部填充有坑槽土层，管沟底板下方填充有管沟垫层，管沟垫层下方填充有原状土层或回填土，管沟盖板与预埋管道顶部之间填充有管道顶部土层，预埋管道顶部以下及预埋管道的管道支承角高度以上填充有管道侧上方土层，预埋管道的管道支承角高度以下及预埋管道底部以上填充有管道侧下方土层，预埋管道底部与管沟底板之间填充有管道底部土层。本发明符合管土协同作用假定、方便施工，同时保证土层的回填质量，在使用阶段便于检修，减少开挖工作量，缩短作业时间，降低对周边环境的干扰，达到快速、安全的目标。
