Beschreibung
Zusammenfassung:	The invention provides a rapid curing agent for pipe-jacking construction slurry and a rapid curing method, the rapid curing agent for pipe-jacking construction slurry is prepared by mixing a component A and a component B. The component A is a main material and comprises CaCO3, CaO, a ground gypsum composition and rapid hardening Portland cement, the total weight of CaCO3, CaO and the ground gypsum composition accounts for 60-80% of the total weight of the rapid curing agent, and the total weight of the rapid hardening Portland cement accounts for 60-80% of the total weight of the rapid curing agent. The weight of the rapid hardening Portland cement accounts for 5-25% of the total weight of the rapid curing agent; the component B is an auxiliary material and comprises water glass, macromolecular polyacrylamide and SBR latex, the weight of the water glass accounts for 0-15% of the total weight of the rapid curing agent, and the sum of the weight of the macromolecular polyacrylamide and the weight of the SBR la
