Construction method of lime soil compaction pile added with glutinous rice slurry
The invention provides a construction method of a lime soil compaction pile added with glutinous rice slurry. According to the construction method of the lime soil compaction pile added with the glutinous rice slurry, lime soil and the glutinous rice slurry are prepared for layer-by-layer backfilling according to the work amount of the compaction pile, and meanwhile the compaction pile is tamped; because the density of the glutinous rice slurry has little influence on the permeability coefficient of a soil body, the permeability coefficient is gradually reduced along with the increase of the content of the glutinous rice slurry, the lime soil is gradually hardened, the strength among soil particles is increased, the bearing capacity of the compaction pile is improved, meanwhile, the glutinous rice slurry improves the cohesive force among the soil particles of the lime soil, and the compactness of backfill soil is further improved; and the method has the advantages that a pile body is compact, the bearing capacity is high, the cost is low, and the practicability is high.
一种添加糯米浆的灰土挤密桩的施工方法，通过挤密桩的工程量，配制灰土及糯米浆用于逐层回填，同时夯实挤密桩；由于糯米浆密度对土体渗透系数影响不大，随着糯米浆含量的增加，渗透系数逐渐减小，使得灰土逐渐硬化，增加了土壤颗粒间的强度，提升了挤密桩的承载力，同时糯米浆提高了灰土的土颗粒间的粘聚力，进而提高回填土的密实度；本发明具有桩身紧实、承载力强、成本低廉及实用性强的优点。
