Pipe ditch earthwork backfilling method
The invention belongs to the technical field of earthwork backfilling, and particularly relates to a pipe ditch earthwork backfilling method which comprises the following steps: S4, backfilling inspection: ensuring that no water is accumulated in a ditch during backfilling, and ensuring that the bottom layer of the pipe ditch is an original soil layer and is flat and smooth in gradient; s5, earthwork backfilling is conducted, specifically, when backfilling is conducted on the pipe trench, backfilling is conducted with excavated soil within 200 mm of the upper portion of the pipe top or within 300 mm of the periphery of the cable; s6, backfilling and compacting: simultaneously and symmetrically backfilling from two sides of structures such as a pipeline and an inspection well during groove backfilling, performing layered compacting to ensure that the pipeline does not generate displacement, and taking a limiting measure if necessary; s7, executing strictly according to the requirements in the soil backfilling process so as to ensure that the pipeline is not damaged in the pipe ditch backfilling project; the backfilling is carried out through the steps, it can be guaranteed that the pipe ditch is compacted thoroughly and firmly in the backfilling process, the bearing capacity of the pipe ditch is increased, and the backfilling quality of the pipe ditch is improved.
本发明属于土方回填技术领域，具体的说是一种管沟土方回填方法，包括以下步骤：S4、回填检查：回填时保证沟槽无积水，在管沟的底层应是原土层，且应平整，坡度顺畅；S5、土方回填：管沟回填土时，管顶上部200mm以内或电缆周围300mm以内用挖方好土回填；S6、回填压实：沟槽回填时应从管道、检查井等构筑物两侧同时对称回填，分层压实，确保管道不产生位移，必要时可采取限位措施；S7、在回填土过程中严格按照上述要求执行，以确保在管沟回填工程中管道不受损坏；通过上述步骤进行回填，能够保证管沟在回填过程中，压实彻底，牢固，使得管沟的承载力变高，提高管沟回填的质量。
