Preparation method of grouting material formed by shield muck
The invention relates to the technical field of shield muck, and discloses a preparation method of a grouting material formed by shield muck, the grouting material comprises a main material, a grouting agent and an additive according to the mass ratio of the main material to the grouting agent to the additive of (60-90): (10-30): (0.05-0.3); the main material comprises slurry formed by shield muck and a sand material, the grouting agent comprises Portland cement, sulphoaluminate cement, mineral powder, gypsum, fly ash and stone powder, and the additive comprises a water reducing agent and a retarder; the preparation method comprises the following steps: firstly stirring and mixing slurry and sand to form a main material, then adding a grouting agent and an additive into the main material, and uniformly stirring and mixing the main material, the grouting agent and the additive to form the grouting material. Thus, the grouting material can be poured into the pipe wall interval between the pipe piece and the soil body to generate a solid structure with certain strength, the bonding force and stability of the pipe piece and the surrounding soil body are improved, the stability of a tunnel structure is enhanced, water permeation is prevented, and the problem of absorption of shield muck can be solved.
本发明涉及盾构渣土的技术领域，公开了盾构渣土形成注浆材料的制备方法，包括主料、注浆剂以及外加剂，按照组分质量比例，主料、注浆剂以及外加剂的比例为(60～90)∶(10～30)∶(0.05～0.3)；主料包括盾构渣土形成的泥浆以及砂料，注浆剂包括硅酸盐水泥、硫铝酸盐水泥、矿粉、石膏、粉煤灰以及石粉，外加剂包括减水剂和缓凝剂；将泥浆与砂料先进行搅拌混合后，形成主料，再在主料中加入注浆剂以及外加剂，并将主料、注浆剂以及外加剂搅拌混合均匀，形成注浆材料。这样，注浆材料可灌注到管片与土体之间的管壁间隔中，生成一定强度的固体结构，提高管片与周围土体的粘结力和稳定性，增强隧道结构的稳定性，并防止水的渗入，还可以解决盾构渣土的消纳问题。
