Foundation construction method capable of eliminating freeze-thaw environment influence
The invention relates to a foundation construction method capable of eliminating freeze-thaw environmental influence. The method comprises the steps that lime soil and NaOH solution with the volume ratio of lime to clay being 20%-30%: 70%-80% are prepared through the engineering quantity of compaction piles and used for backfilling layer by layer, and meanwhile the compaction piles are tamped. Due to the fact that the density of the NaOH solution has little influence on the permeability coefficient of the soil body, the lime soil is gradually hardened along with the increase of the content of the NaOH solution and the improvement of the frost resistance, the strength among soil particles is increased, the bearing capacity of the compaction piles is improved, meanwhile, the cohesive force among the soil particles of the lime soil is improved by the NaOH solution, and the compactness of the backfill soil is further improved; and the method has the advantages of freeze thawing resistance, compact pile body, high bearing capacity, low cost and high practicability.
一种消除冻融环境影响的地基的施工方法，通过挤密桩的工程量，配制石灰与黏土体积比为20％‑30％:70％‑80％的灰土及NaOH溶液，用于逐层回填，同时夯实挤密桩；由于NaOH溶液密度对土体渗透系数影响不大，随着NaOH溶液含量的增加，抗冻性提高，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NaOH溶液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；本发明具有抗冻融、桩身紧实、承载力强、成本低廉及实用性强的优点。
