Preparation process method of premixed flow-state filling material
The invention discloses a preparation process method of a premixed flow-state filling material, which comprises the following steps: carrying out mud decomposition on sand-washing filter-pressing filter mud which is a solid or semi-solid soil sample, putting the mud-decomposed material into a pulping machine for pulping treatment, carrying out mud decomposition on river sludge, wet soil and/or harmless waterworks tail mud, and carrying out mud decomposition on the mud-decomposed material to obtain the premixed flow-state filling material. The preparation process comprises the following steps: adding mud into a pulping machine for pulping, mixing the materials for preparing the pulp, screening by a screening machine, homogenizing in a pre-homogenizing tank, stirring and homogenizing in the pre-homogenizing tank, stirring and homogenizing in a stirrer, and discharging after stirring. Pasty mucky soil with high moisture content and large change and filter pressing filter mud are prepared into slurry in a designed density range, so that the stability of raw materials is controlled, the influence of fluctuation of the moisture content of the raw materials is eliminated, the curing time is greatly shortened, the hardening degree is improved, the long-term stability is greatly improved, and the cost is saved.
本发明公开了一种预拌流态填筑料制备工艺方法，将洗砂压滤滤泥，其为固体或半固体土样，进行解泥，解泥后的物料投入制浆机进行制浆处理，将河道淤泥、潮湿土壤和/或无害的自来水厂尾泥进行解泥，解泥后的物料投入制浆机进行制浆处理，将上述制备制浆的物料混合，经筛分机筛分，进入预均化池均化处理，预均化池搅拌均化处理后进入搅拌机进行搅拌，均匀化，搅拌后出料，本发明的预制浆制备工艺，通过将含水率较高且变化较大的膏状淤泥质土及压滤滤泥制备成设计密度范围的浆体，来控制原材料的稳定性，排除原材料含水率波动的影响，大幅降低了固化时间，提高了硬化度，极大地增加了长期稳定性，节约了成本。
