The corrugated steel culvert is replaced slab culvert, and high quality of highway bridge construction. The structure of metal corrugated culvert is reasonable, the load distribution is uniform, and has a certain resistance to deformation.
1, the structure is rammed with the machine nearby, and the sand at the lower part of the pipe bottom is vibrated with a watertight method.
2, both sides should be symmetrical construction of culvert backfill, the thickness of each layer is 20cm, the compaction degree is not less than 93%.
3, above the culvert when the backfill thickness is less than 50cm by manual vibrating road roller compaction or by small.
