In-situ treatment technology for high-water-content engineering residue soil

The invention provides an in-situ treatment method for high-water-content muck, which can be used for treating engineering muck with the water content higher than 60%, and specifically comprises the following steps: through compound use of uncalcined gypsum and calcined gypsum, a large amount of water in the engineering muck is absorbed, and meanwhile, furnace bottom ash is used for reducing the influence of the water in the high-water-content muck on a curing material. The types of the gypsum used in the invention relate to titanium gypsum, phosphogypsum and desulfurized gypsum, the related gypsum types are wide, the raw materials are all industrial products, the utilization rate of solid waste materials in the curing material reaches 65%-100%, the emission of solid wastes in industrial production is reduced, and the material has the advantage of environmental friendliness and is a green building material; meanwhile, the muck treated by using the engineering muck in-situ treatment technology provided by the
