Curing agent for curing bentonite slurry and construction method thereof

The invention relates to the technical field of pile foundation construction, and discloses a curing agent for curing bentonite slurry and a construction method thereof, and the curing agent comprises the following main cost components: cement clinker 10-30:quick lime 8-15:superfine slag powder 25-35:fly ash 12-25:desulfurized gypsum 5-15:sodium bicarbonate 0.8-1.5:lignosulfonate 1-2:an accelerator 1-5. The curing agent with the raw material component ratio is low in mixing amount in practical application when being mixed with bentonite slurry, the mixing amount is 15-25% of the weight of the bentonite slurry, the using amount of the curing agent is saved, and the compressive strength is 0.8 Mpa or above. The construction method adopted according to the raw material ratio comprises the following steps: S1, stirring the powdery curing agent according to the parameter conditions of the pile hole and the bentonite slurry; S2, connecting and debugging the air compressor and the injection machine; S3, adding a pow
