Shield synchronous grouting material and preparation method thereof
The invention relates to the technical field of tunnel construction materials, in particular to a shield synchronous grouting material and a preparation method thereof. The shield synchronous grouting material comprises the following components in parts by weight: 100 parts of mud cake, 8-20 parts of fly ash, 1-4 parts of sodium silicate, 4-16 parts of silicon powder, 20 parts of cement and the balance of water, the water-solid ratio is 1: (0.8-0.95). The preparation method comprises the following steps: weighing a mud cake, crushing, adding water, and stirring to form slurry; weighing the fly ash, the sodium silicate, the silicon powder and the cement according to the mass ratio, adding into the slurry, uniformly mixing, and stirring for 5-10 minutes; the method comprises the following steps: adding an admixture according to actual requirements on site before construction, and fully mixing and stirring, wherein the addition amount of the admixture is 0.15-0.3% of the mass of the cement. The method has the advantages that the mud cake is used as a main material, and a small amount of cement, fly ash, mineral powder and the like are used as cementing materials, so that the shield construction cost is greatly reduced, and low carbonization of subway construction is promoted to a certain extent.
本发明涉及隧道施工材料技术领域，尤其涉及一种盾构同步注浆材料及其制备方法。一种盾构同步注浆材料，按重量计包括如下组分：泥饼100份、粉煤灰8～20份、硅酸钠1～4份、硅粉4～16份、水泥20份，余量为水；水固比为1：0.8～0.95。制备方法包括：称取泥饼，进行破碎，加水搅拌形成浆液；按质量比例称取粉煤灰、硅酸钠、硅粉、水泥，加入至浆液中混合均匀，搅拌5～10分钟；在临近施工前根据现场实际需求加入外加剂，添加量为所述水泥质量的0.15～0.3％，充分混合搅拌。优点在于：采用泥饼作为主要材料，以少量水泥及粉煤灰、矿粉等作为胶凝材料，极大降低盾构施工成本，也在一定程度上推动地铁施工的低碳化。
