Zusammenfassung:The invention relates to the technical field of concrete spraying, in particular to a construction method for low-resilience sprayed concrete. Comprising the following steps: S1, selecting shotcrete raw materials, and preparing shotcrete; s2, designing a concrete mix proportion; s3, concrete stirring, wherein a full-automatic metering forced stirrer is adopted for wet spraying concrete stirring; s4, concrete transportation; s5, preparation before spraying: checking the size of an excavated section, removing floating slag, and cleaning a sprayed surface; s6, concrete spraying operation is carried out; s7, curing operation, wherein after the sprayed concrete is finally set for 2 hours, curing is conducted; s8, quality inspection; and S9, detecting the rebound rate. The strength of the concrete constructed through the construction method is guaranteed, the spraying homogeneity is good, the production rate is high, dust is avoided during construction, the rebound rate is low, bleeding of the sprayed concrete is r
