| description | The invention relates to a bridge and culvert abutment back hanging plate retaining type foam light soil backfill construction method. The method comprises the steps that S1, construction preparation is conducted; debugging a prefabricated hanging plate and foam light soil mixing device, and verifying a test mix proportion; s2, an abutment back is processed, the bearing capacity is detected, test lofting is conducted, and a backfill area is determined; s3, hanging plate construction; hanging plates are arranged around the backfill area to prevent backfill materials in the backfill area from flowing out; s4, foam light soil is mixed, and the foam light soil is poured on the first layer of the backfill area; s5, preserving; s6, the steps S3-S5 are repeated, the next layer of hanging plate construction is conducted, and backfilling continues to be conducted till the backfilling height is reached; the method has the effect of reducing differential settlement in abutment back backfilling engineering.
