Ready-mixed fluidized solidified soil is to make full use of the foundation soil, muck and other materials discarded after the excavation of the fertilizer tank and foundation pit, absorb the spoil on the site, add a certain proportion of special cementitious materials (curing agent) and water, and mix evenly through a series of processes and special machinery to form self-leveling, self-compacting, pumpable engineering materials, after pouring or filling, curing, so that it is cured into a new type of geotechnical engineering material with a certain strength, impermeability, and long-term stability.
1) Backfill: atrial core, pipeline, pipe trench, road and bridge, foundation groove seepage prevention and backfill, temporary site hardening, road water stabilized layer.
2) Pile body: composite foundation reinforcement or stiff composite pile, mixing pile, jet grouting pile waterproof curtain, gravity wall support body, continuous wall, long spiral pressure grouting pile, bored pile.
3) Filling: mine goaf, ground collapse cavity, abandoned underground space, karst cave grouting filling.
4) Replacement: soft foundation replacement, pipe foundation replacement, low-lying site replacement, etc.

Fluidized solidified soil house heart backfill - Hubei Jiaotou Tianhe Huafu project
The project is located in Fenghuanggang Avenue, Airport Economic Zone, Xiaogan City, Hubei Province, with a construction area of about 15870,000 m, the main structure has been completed, and the backfill space in the center of the house is limited. Considering the cost and environmental protection, it was decided to take local materials and use the waste muck of the foundation pit as raw materials to prepare fluidized solidified soil for backfilling, which is faster and has good results.
