Foam light soil composition for abutment back backfilling under high water level condition, preparation device and method
The invention relates to a foam light soil composition for abutment back backfilling under a high water level condition, a preparation device and a method, and the foam light soil composition comprises ground steel slag micro powder, fly ash, desulfurized gypsum, cement and an expanding agent which are used as a layer solid mixture, and fly ash and a surfactant which are used as intermediate slurry, the foaming agent is sprayed on the layer solid mixture and the middle slurry, so that outward foaming treatment between the layer solid mixture and the middle slurry is realized, and the space volume of the abutment back roadbed raw material is increased; the technical problem that the pressure generated on the abutment back roadbed raw material mainly composed of concrete and gravel and the abutment back is increased is solved, meanwhile, the good water stability of the backfill material is guaranteed, and therefore the backfill material is suitable for being used as the abutment back backfill material under the high-water-level condition.
一种用于高水位条件下台背回填泡沫轻质土组合物、制备装置和方法，包含有用于作为层体固体混合物的磨细钢渣微粉、粉煤灰、脱硫石膏、水泥和膨胀剂，用于作为中间浆体的除尘灰和表面活性剂，用于喷洒在层体固体混合物和中间浆体上的发泡剂，实现了在层体固体混合物和中间浆体之间进行向外发泡处理，增大了台背路基原料的空间体积，解决了对以三合土和砂石的主要组成物的台背路基原料并且对桥台台背产生的压力增大的技术问题，同时保证了回填材料良好的水稳定性，因此适合作为高水位条件下台背回填材料使用。
