Rapid preparation method of high-strength uniform-flow-state solidified filled soil
The invention discloses a rapid preparation method of high-strength uniform-flow-state solidified filled soil, a certain amount of agglomeration water separating agent is doped into a special curing agent, under the action of the agglomeration water separating agent, the double-electrode layer thickness of soil particles is compressed, clay particles are agglomerated, and the permeability of a soil body is increased, so that pore water in the soil is more easily separated out, the flowability of the mixture, namely the flow-state solidified soil, is not influenced; after filling, a vibrator and a vacuum water suction device are matched for use to suck separated free water, so that the water content of the mixture is reduced; the product has good fluidity during filling, and can form a high-strength filling material after absorbing a certain amount of water. According to the invention, the uniformity of the fluid solidified soil is effectively improved, redundant pore water is absorbed and removed, the excavated waste soft soil can be quickly converted into a backfill material with better fluidity, the backfill material has higher strength after maintenance, the backfill material can be used for foundation trench backfill, excavated road backfill and the like, and the resource utilization of the excavated waste soft soil is realized.
本发明公开了一种高强度均匀流态固化填充土的快速制备方法，在专用固化剂中掺入一定量的团聚析水剂，在团聚析水剂的作用下，土颗粒双电层厚度压缩、粘土颗粒团聚、土体渗透性增加，从而促使土中的孔隙水更容易析出，但并不影响混合物即流态固化土的流动性；填筑后用振捣器和真空吸水装置配合使用，吸除析出的自由水，使混合物的含水率下降；达到既能在填充时具有较好的流动性，又能在吸除一定量水分后形成高强度填充材料的目的。本发明有效改善流态固化土的均匀性，吸除多余的孔隙水，既能够将开挖废弃软土快速转化为具有较好的流动性的回填料，又能在养护后具有较高强度，可用于基槽回填、开挖道路回填等，实现开挖废弃软土的资源化利用。
