Impermeable shield inert synchronous grouting material and preparation method thereof
The invention discloses an impervious shield inert synchronous grouting material and a preparation method thereof. The impervious shield inert synchronous grouting material is prepared from the following raw materials in percentage by mass: 19%-28% of an inert cementing material, 45%-50% of river sand, 7%-10% of sodium bentonite, 4%-8% of a reinforcing-impervious complexing agent, 11.8%-15.7% of water and 0.1%-1% of a water reducing agent, and the total content of the raw materials is 100%. Wherein the inert cementing material is a mixture of superfine slag powder, fly ash and silica fume, and the mass ratio of the superfine slag powder to the fly ash to the silica fume is (14-18): (3-5): (2-5). The preparation method is based on solid waste resource recycling, the prepared shield inert synchronous grouting material is good in workability, good in pumpability and excellent in waterproof and anti-seepage performance, and durability and structural stability of tunnel prefabricated segments are guaranteed.
本发明公开了一种抗渗型盾构惰性同步注浆材料及其制备方法，由以下质量百分含量的原料组成：惰性胶凝材料：19％～28％，河砂45％～50％，钠基膨润土7％～10％，增强‑抗渗复合剂4％～8％，水11.8％～15.7％，减水剂0.1～1％，上述原料总含量为100％；其中：惰性胶凝材料为矿渣微粉、粉煤灰、硅灰的混合物，所述矿渣微粉、粉煤灰和硅灰的质量比为(14～18)：(3～5)：(2～5)。该制备方法基于固废资源回用，制备出的盾构惰性同步注浆材料了和易性良好、泵送性好，且防水抗渗性能优良，保证了隧道预制管片耐久性和结构稳定性。
