Preparation method of muck fluidized composite backfill material
The invention relates to the technical field of municipal engineering construction, and discloses a preparation method of a muck fluidized composite backfill material. The preparation method comprises the following steps: S01, removing impurities from muck; S02, firstly adding the impurity-removed muck into preparation equipment of the muck fluidized composite backfill material, then adding cement, lime and an expanding agent separately, and stirring to form powder; S03, adding a certain amount of water into the powder to make the powder in a half-flow state to form a muck mixture and preparing slurry, specifically, the water adding amount accounts for 60%-80% of the total water amount, and a water reducing agent, a curing agent and a proper amount of water are mixed uniformly to form slurry; and S04, stirring the prepared slurry and the premixed muck mixture to be uniform to form the muck fluidized composite backfill material. Compared with similar products, the muck fluidized composite backfill material has the advantages of being free of compaction, high in flowability, controllable in strength and curing time, free of contractility or micro-expansibility, good in stability, not prone to segregation, high in applicability, capable of consuming engineering residue soil, simple and convenient to produce, and low in cost.
本发明涉及市政工程建设的技术领域，公开了渣土流动化复合回填材料的制备方法，包括以下步骤：S01：渣土去杂；S02：在渣土流动化复合回填材料的制备设备中先加入去杂渣土，然后再分别加入水泥、石灰和膨胀剂，进行搅拌形成粉料；S03：向粉料中加入一定量的水，加水量为总用水量的60％～80％，使粉料呈半流动态，形成渣土混合料；浆液配制：将减水剂、固化剂与适量水均匀混合形成浆液；S04：将配制好的浆液与预拌好的渣土混合料搅拌至均匀，形成渣土流动化复合回填材料。相较于同类产品的优势是：免压实，流动性高；强度可控、固化时间可控；无收缩性或微膨胀性；稳定性好不易离析；适用性强可消耗工程渣土；生产简便、造价不高。
