[0026] Example 1, a fast consolidation method suitable for soft foundation of silt, the steps are as follows: in the in-situ of the shallow dredging sludge to be treated, adding alkali-making waste, carbon slag and non-ionic to the dredging sludge Surfactant, stirring, react at natural temperature; the added amount of soda slag is 8% of the weight of the filling sludge, and the added amount of non-ionic surfactant is 3‰ of the soda slag; The added amount is 3% of the weight of the dredging sludge, and the reinforcement depth of the dredging sludge is 1-2 meters; after the reaction is completed, a vacuum jet pump is used to vacuum water to complete the rapid consolidation of the silt soft foundation. After the soil is consolidated The site is used as a working cushion; the soda-making waste residue refers to the waste residue from the production of soda ash, which contains Ca ions. When the vacuum jet pump is used for vacuum suction, the suction flow of the jet pump is 10 m 3 / h...
