1. A synchronous single-liquid grouting slurry for large diameter shield engineering under water-rich, high-pressure and weak soil strata conditions, comprising the following weights of raw materials: 1050-1200 parts of gold tailing, 420-480 parts of silicate cement clinker, 220-240 parts of fly ash, 45-120 parts of waste clay brick, 65-95 parts of slag, 25-45 parts of limestone tailing, 70-80 parts of steel slag, 30-45 parts of silica fume, 15-22 parts of desulfurized gypsum, and 9-15 parts of quick-setting and early-strength composite additive,
wherein the quick-setting and early-strength composite additive comprises the following weight percents of raw materials: 30-35% of calcium formate, 30-35% of triethanolamine, 15-20% of sodium aluminate, 10-15% of calcium nitrite; wherein the gold tailing comprises a gold tailing I with a maximum particle size dmax of particles less than 120 μm, and a gold tailing II with a particle size between 120-600 μm, and a volume fraction of the gold tailing II is about 40-60% in the total volume of the slurry.
