Shield backfill grouting slurry and preparation method thereof
The invention relates to the technical field of shield grouting, in particular to shield backfill grouting slurry and a preparation method thereof. The slurry comprises the following components in percentage by weight: 8-10% of a curing agent, 8-12% of Portland cement and 78-84% of silty clay. The curing agent comprises the following components in percentage by weight: 8 to 12 percent of semi-hydrated gypsum, 40 to 45 percent of calcium aluminate, 30 to 40 percent of silica powder, 5 to 10 percent of alunite and 5 to 10 percent of quick lime. The preparation method comprises the following steps: stirring and mixing the prepared curing agent, the Portland cement and the silty clay with water. Through cooperation of the raw materials, the grouting slurry with high strength, high waterproofness, high temperature resistance and high acid and alkali corrosion resistance can be prepared. The grouting slurry can be prepared by mixing and stirring the raw materials with water, the groutability of the grouting slurry is high, the grouting slurry can be suitable for a common grouting machine, the requirement for grouting equipment is low, and the application range of the grouting slurry is greatly widened.
本发明涉及盾构注浆技术领域，具体涉及一种盾构壁后注浆浆液及其制备方法。浆液包括如下重量百分比的各组分：固化剂8～10％、硅酸盐水泥8～12％和粉质黏土78～84％。所述固化剂中半水石膏、铝酸钙、硅微粉、明矾石和生石灰所占的重量百分比为：半水石膏8～12％、铝酸钙40～45％、硅微粉30～40％、明矾石5～10％、生石灰5～10％。制备方法为将制备好的固化剂与硅酸盐水泥和粉质黏土加水搅拌混合。本发明通过原料间的配合，能够制备强度高、防水性强、耐温性强、耐酸碱腐蚀性强的注浆浆液。本发明通过将原料加水混合搅拌即可制得，注浆的浆液可注性强，普通注浆机即可适用，对注浆设备的要求较低，大大提高了注浆浆液的实用范围。
