Shield muck deposition area surface soft soil curing agent, modified soil material and preparation method of modified soil material
The invention discloses a shield muck deposition area surface layer soft soil curing agent, a modified soil material and a preparation method of the shield muck deposition area surface layer soft soil curing agent and the modified soil material. 4-6 parts by weight of quick lime; 0.15 to 0.3 part by weight of polyacrylamide; 0.4 to 0.7 part by weight of anhydrous sodium metasilicate; and 0.25 to 0.55 part by weight of sodium alginate. The curing agent disclosed by the invention is simple in composition, low in cost and convenient in construction operation, effectively realizes control on the content of heavy metals in shield muck solidified soil leachate, prevents secondary pollution caused by solidified soil, effectively improves the structural form of surface soft soil in a shield muck silting area, and has a better application prospect.
本发明公开了盾构渣土淤积区表层软土固化剂、改性土材料及其制备方法，其中固化剂，包括，以重量份数计：普通硅酸盐水泥9‑12重量份；生石灰4‑6重量份；聚丙烯酰胺0.15‑0.3重量份；无水偏硅酸钠0.4‑0.7重量份；海藻酸钠0.25‑0.55重量份。本发明的固化剂，组成简单，成本低廉，施工作业操作便利，有效地实现了对盾构渣土固化土浸出液中重金属含量的控制，防止固化土带来二次污染，有效改善了盾构渣土淤积区表层软土的结构形态，具有更好的应用前景。
