Subway shield waste mud modification treatment and cyclic utilization construction method
The invention relates to the technical field of recycling of waste slurry, in particular to a modification treatment and recycling construction method for subway shield waste slurry. The method comprises the steps that subway shield waste mud is obtained; the mass fraction of montmorillonite in a solid-phase component obtained after the subway shield waste slurry is dried is 30% or above; the subway shield waste slurry is screened, and pretreated waste slurry is obtained; the sand content of the pretreated waste slurry is lower than a set sand content; measuring an original state index of the pretreated waste slurry; determining a modification formula; and modifying the pretreated waste slurry according to the modification formula, and then carrying out field construction application. By adopting the method disclosed by the invention, the subway shield waste mud can be converted into resource cyclic utilization from existing discarding and transporting treatment, so that the discharge of the subway shield waste mud is reduced, the resource utilization of construction wastes is promoted, and the ecological environment is protected.
本发明涉及废弃泥浆回收利用技术领域，具体而言，涉及一种地铁盾构废弃泥浆改性处理循环利用施工方法；该方法包括：获取地铁盾构废弃泥浆；所述地铁盾构废弃泥浆烘干后所得的固相成分中蒙脱石的质量分数为30％以上；将所述地铁盾构废弃泥浆进行筛分处理，得到预处理废弃泥浆；所述预处理废弃泥浆的含砂率低于设定含砂率；测定所述预处理废弃泥浆的原始状态指标；确定改性配方；根据所述改性配方对得到的所述预处理废弃泥浆改性后，进行现场施工应用。采用本发明的方法，可使地铁盾构废弃泥浆从现有的弃运处置，转变为资源化循环利用，减少了地铁盾构废弃泥浆排放，推进建筑垃圾资源化利用，保护了生态环境。
