Shield residue soil replacement type shield segment post-grouting environment-friendly slurry
The invention discloses a shield residue soil replacement type shield segment post-grouting environment-friendly slurry, the synchronous grouting slurry is composed of the following raw materials in percentage by mass: 5-25% of 42.5 R ordinary Portland cement, 25-50% of soil, 10-20% of a mixture, and the balance of water, and the mixture is composed of slag and fly ash; compared with traditional shield synchronous grouting, the slurry fluidity and shrinkage resistance are good, stability and consolidation are high, the slurry can be well injected into a stratum through a shield supporting ring and a shield tail inner pipeline system, and meanwhile materials are environmentally friendly and energy-saving. The components of the grouting slurry are all materials used by traditional synchronous grouting slurry, other additives are not needed, and the quality requirement of the synchronous grouting slurry of the water stratum can be met. Compared with other types of water dispersion resistant slurry, the material has the obvious advantage of low construction cost. The preparation method is simple, has outstanding environmental protection performance, can meet the requirements of construction sites, and has good economic benefits and social benefits.
本发明公开了一种盾构渣土替代型盾构管片后注浆的环保浆液，所述同步注浆的浆液由以下质量百分比原料组成：42.5R普通硅酸盐水泥5‑25%、泥土25‑50%、混合料10‑20%，余量为水，其中混合料由矿渣与粉煤灰组成；本发明与传统的盾构同步注浆相比，浆体流动性和抗收缩较好，稳定性和固结性强，可以很好的可以通过盾构支撑环和盾尾内管道系统注入地层内，同时材料环保节能。本发明所用的注浆浆液材料组成均为传统同步注浆浆液所用材料，且无需其他外加剂，即可满足水地层的同步注浆浆液质量要求。材料与其他类型抗水分散浆液相比，本发明具有明显施工成本低廉的优势。本发明所涉及的制备方法简单，环保性能突出，能够满足施工现场的要求，具有良好的经济效益及社会效益。
