Shield muck synchronous grouting material and preparation method thereof
The invention relates to the field of tunnel construction materials, and particularly discloses a shield muck synchronous grouting material and a preparation method thereof.The shield muck synchronous grouting material is mainly prepared from, by weight, 1 part of shield muck, 0.5-1.0 part of slag powder, 2.1-2.4 parts of sand, 0.15 part of slaked lime, 0.15 part of anhydrous sodium sulfate and 1.1-1.4 parts of water. The synchronous grouting material prepared by the method is relatively good in various properties. The preparation method of the synchronous grouting material is simple in step, convenient to operate and beneficial to follow-up application and popularization. In addition, the synchronous grouting material is prepared by using the cohesive soil layer shield muck and the geopolymer slag powder as the cementing material, so that the shield muck can be consumed, the carbon emission can be reduced while the resource reutilization of the muck can be realized, and the synchronous grouting material has important significance on environmental protection and conforms to the policy of energy conservation and emission reduction. And the construction cost can be saved for enterprises, and the economic pressure and the social pressure caused by muck treatment of subway construction units can be relieved.
本申请涉及隧道施工材料领域，具体公开了一种盾构渣土同步注浆材料及其制备方法，本申请中同步注浆材料主要包括1重量份的盾构渣土，0.5‑1.0重量份的矿渣粉，2.1‑2.4重量份的砂，0.15重量份的熟石灰，0.15重量份的无水硫酸钠，1.1‑1.4重量份的水，由此制备得到的同步注浆材料的各项性能较好。本申请中同步注浆材料的制备方法步骤简洁且操作便捷，有助于后续推广应用。此外，利用黏性土地层盾构渣土，采用地聚合物矿渣粉作为胶结材料，制备同步注浆材料可以消耗盾构渣土，能够实现渣土资源化再利用的同时减少碳排放量，对环境保护有着重要意义，符合“节能减排”的政策。也能够为企业节省施工成本，有助于缓解地铁施工单位渣土处理所带来的经济压力和社会压力。
