Bridge and culvert abutment back hanging plate retaining type foam light soil backfill construction method
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.
本申请涉及一种桥涵台背挂板支档式泡沫轻质土回填施工工法，其包括S1：施工准备；预制挂板，泡沫轻质土拌合设备调试，试验配合比验证；S2：台背处理并检测承载力，测试放样，确定回填区域；S3：挂板施工；使用挂板围绕回填区域设置，阻挡回填区域的回填物外流；S4：拌合泡沫轻质土，并在回填区域一层浇筑泡沫轻质土；S5：养生；S6：重复S3~S5，转入下一层挂板施工并继续进行回填，直至达到回填高度；本申请具有减少台背回填工程中的不均匀沉降的效果。
