Manufacturing method of high-strength cement-soil mortar pile
The invention discloses a manufacturing method of a high-strength cement-soil mortar pile, and relates to the field of civil engineering materials, and the manufacturing method comprises the following steps: performing in-situ drilling and soil taking on a muddy soft soil foundation; mixing and stirring the soil, the dispersing agent, the air entraining agent, the curing material and the water blocking agent in sequence to obtain the flow-state cured soil slurry; the prepared flow-state solidified soil slurry is conveyed into an in-situ hole through a special construction technology, and a complete pile body is formed. Wherein a certain amount of fine aggregate and an air entraining agent are added into the curing material, so that the fluidity required by infusion is met, the strength of a pile body reaches 8MPa or above within 28d, and the problems of low strength, non-uniformity of the pile body and the like of a traditional cement mixing pile are solved.
本发明公开了一种高强度水泥土胶砂桩的制作方法，涉及到土木工程材料领域，包含以下步骤：对淤泥质软土地基进行原位钻孔、取土；将土和分散剂、引气剂、固化料、阻水剂依次混合搅拌流态固化土浆液；利用特殊施工工艺将制备好的流态固化土浆液输送至原位孔中，形成完整的桩体。其中所述的固化料中添加了一定量的细骨料和引气剂，既满足了灌输要求的流动度同时又实现桩身强度28d达到8MPa以上，解决了传统水泥搅拌桩强度低和桩身不均匀等问题。
