The invention discloses a soft soil foundation indoor terrace settlement grouting material. The grouting material comprises blast furnace ferronickel slag powder, an admixture, machine-made sand waste stone powder, sodium silicate, borax, sodium polyphosphate, citric acid, sodium carbonate and water. The water-to-material ratio of the grouting material to the water is determined. The invention further provides a reinforcement method adopting the grouting material for settlement of the indoor terrace of the soft soil foundation. The invention has the following technical effects: 1, a novel grouting material is developed from wastes, which is beneficial to recycling of wastes and is low-carbon and environment-friendly; 2, the reinforcement method is simple and feasible, and the optimal mix proportion of the grouting material is obtained; 3, the strength of the grouting material can reach 30-60 MPA, and the original bearing capacity can be improved by more than 200% after grouting reinforcement; and 4, a grouting reinforcement and settlement control method for pot bottom type settlement of the indoor foundation of the industrial factory building in the coastal area is provided, so that the settlement speed can be controlled within a standard range, the use requirements of owners are met, and soil disturbance and ground settlement increase caused by excavation are avoided.
本发明公开软土地基室内地坪沉降注浆材料所述注浆材料包括高炉镍铁矿渣粉、掺合料、机制砂废石粉、硅酸钠、硼砂、多聚磷酸钠、柠檬酸、碳酸钠和水。所述注浆材料与水的水料比。本发明还提供采用软土地基室内地坪沉降注浆材料所述注浆材料的加固发方法。技术效果如下：1、利用废弃物开发出新型的注浆材料，有利于废弃物的循环利用、低碳环保；2、加固方法，简单可行获得了注浆材料的最佳配合比；3、注浆材料的强度可达到30‑60MPA，注浆加固后可提高原有承载力200％以上；4、提出了沿海地区工业厂房室内地基锅底式下沉的注浆加固和控制沉降的方法，可将沉降速度可控在规范以内，满足了业主的使用要求，避免开挖导致的土体扰动，加大地面的沉降。
