And various sundries.Filler has to comply with design requirement, bankets and horizontal slice paving is answered to fill out, compaction in layers, and should be layered measurement pressure
Filling's dry density after reality can just fill upper layer after its compacting factor and compacting range meet design requirement on inspection.Backfill mistake
Cheng Zhong should must not be backfilled without ponding with water in slot.The structures two sides such as trench backfill Ying Xiancong pipeline, catch-basin symmetrically backfill
Ensure that pipeline and structures do not generate displacement.After pipeline laying, tube top 0.5m or more, should be by until in roadbase bottom range
Design requirement uses respective material, and is layered flat layered compacting to reach design and code requirement.
During backfill, it should must not be backfilled with water without ponding in slot.The structures such as trench backfill Ying Xiancong pipeline, inspection shaft
Building object two sides and symmetrically backfilling ensures that pipeline and structures do not generate displacement.After pipeline laying, pipeline two sides and the above 0.5m of tube top
Using the backfill of artificial graded gravel (using medium coarse sand around HDPE pipe) backfill, artificial graded gravel match ratio is gravel for part
(0.5~4cm of partial size): medium coarse sand=6:4(volume ratio).Because my segment pipe is predominantly located under road, returned according to design requirement groove
