Shield muck curing agent and resource utilization method thereof
The invention provides a shield muck curing agent. The shield muck curing agent comprises cement, calcium oxide, calcium sulfate and sodium polyacrylate in a mass ratio of (8-15): (4-10): (4-10): (1-4). According to the invention, moisture in shield muck is rapidly absorbed by utilizing the characteristic that sodium polyacrylate is high in water absorption, soil particles are aggregated into clusters through viscous substances generated by sodium polyacrylate, the early-strength shield muck curing agent has an obvious effect, the shield muck is converted into a plastic state from a plastic flow state after being treated by the curing agent, transportation is convenient, therefore, the dilemma that a subway project is shut down due to full load of a muck pool is overcome, the mechanical property of the solidified soil after 7 days of maintenance meets the requirements of roadbed filler, and resource utilization of the shield muck is achieved.
本发明提供一种盾构渣土固化剂,其组成成分及质量比例为:水泥:氧化钙:硫酸钙:聚丙烯酸钠==8‑15:4‑10:4‑10:1‑4。本发明利用聚丙烯酸钠吸水性强的特点将盾构渣土中的水分迅速吸收,聚丙烯酸钠生成的粘性物质将土颗粒聚集成团,早强盾构渣土固化剂具有明显的效果,盾构渣土由流塑状态经过固化剂处理后转变为塑性状态,方便运输,从而解决了地铁项目因渣土池满载而停工的困境,而且养护7d后固化土力学性能满足路基填料要求,实现盾构渣土资源化利用。
