Light foamed soil for abutment back backfilling and construction method
The invention discloses a light foamed soil for abutment back backfilling. The light foamed soil comprises cement, a mixed material, water, a conditioning agent, a foaming agent, a micro-foam agent, and a waterproof agent. The invention also provides a preparation method of light foamed soil for abutment back backfilling. The micro-foam agent is prepared into foams by a plunger pump and an air compressor, the materials are mixed and stirred by a stirrer, and the slurry extraction speed is controlled by a frequency converter so as to control the volume weight of the finished product. The invention also provides an on-site construction method of light foamed soil applied to abutment back backfilling. The light foamed soil provided by the invention belongs to light materials, has small foundation load after filling, greatly reduces the foundation treatment intensity, and saves the foundation treatment duration. After pouring and before initial setting, light foamed soil has very good fluidity and fill self-compaction, avoids the defect of non-full filling of conventional fillers, has strong constructability, and can effectively solve the phenomenon of bumping at bridge head.
