Fluidized solidified soil pile body soft foundation reinforcement construction method
The invention discloses a construction method for reinforcing a soft foundation of a fluid solidified soil pile body, which meets the requirement that a precast pile, a cement pile and a CFG pile with the same strength are replaced under the working condition that the pile body strength is 0.1-10MPa, the formed pile body is uniform in soil texture, a curing agent is configured according to soil texture characteristics, the material metering is accurate, the mixing proportion and the stirring process are controllable, the overall strength fall of the pile body is small, and the bearing performance is better. Meanwhile, the drilled soil is premixed and then is used for preparing the flow-state solidified soil, so that the soil can be utilized on site without outward transportation or small-amount outward transportation, the method is green and environment-friendly, the working procedures of on-site storage, filter-pressing cake forming, outward transportation and the like of slurry discharged during cement mixing pile construction and the process of outward transportation of soil discharged by a long spiral drill of a CFG pile and the cost generated in the processes are avoided, and the cost is reduced.
本发明公开了一种流态固化土桩体软基加固施工方法，满足在桩体强度0.1‑10MPa的工况代替相同强度的预制桩，水泥桩和CFG桩，成型的桩体土质均一，固化剂按照土质特性配置，材料计量精准，配合比、搅拌过程可控，桩体整体强度落差小，承载性能更优，同时钻取土壤预混后进行流态固化土制备，能够将土壤就地利用无需外运或少量外运，绿色环保，本发明避免了水泥搅拌桩施工排出泥浆现场储存、压滤成饼、外运等工序和CFG桩长螺旋钻排出土壤外运过程及以上过程产生的费用，降低成本。
