Preparation method of ecological solidified light soil and ecological solidified light soil
The invention discloses a preparation method of ecological solidified light soil. The preparation method comprises the following steps: crushing residual sludge and a biomass material until the particle size is not more than 10mm, adding water, and stirring until slurry with the density of 1400-1700g/cm < 3 > is obtained; diluting a foaming agent by 50 times and foaming by 30 times to prepare a foam and aerogel mixture; and 2, uniformly mixing and stirring the slurry obtained in step 1 with gypsum, cement, mineral powder and water, heating for a period of time, cooling, adding the mixture obtained in step 3, uniformly stirring to obtain cured light soil, and carrying out casting molding. According to the invention, residual mud and muck dug out or generated in construction of civil engineering, hydraulic engineering and the like are used as raw materials for solidifying light soil, so that waste recycling is effectively realized, environmental pollution is reduced, the use of traditional materials such as soil, gravels, lime, cement and the like is reduced, resources are saved, and the production cost of the solidified light soil is greatly reduced.
本发明公开了一种生态固化轻质土的制备方法，包括步骤：将余泥渣土、生物质材料破细至粒径不大于10mm后加水搅拌至密度为1400‑1700g/cm的浆料；将发泡剂按50倍稀释、30倍发泡制备成泡沫与气凝胶混合物；将步骤1所得的浆料与石膏、水泥、矿粉、水混合搅拌均匀，加热一段时间冷却后，然后再加入步骤3所得的混合物搅拌均匀，得到的固化轻质土，然后进行浇注成型。本发明采用土木、水利工程等施工挖出或产生的余泥渣土为固化轻质土的原料，有效实现废弃物再利用，减少对环境的污染，减少对土、碎石、石灰、水泥等传统材料的使用，节约资源，大幅降低了固化轻质土的生产成本。
