The present invention discloses a block chain-based sleeve grouting quality traceability method and system, and a collection terminal. The method comprises: step S1: establishing a unified quality traceability standard and a data collection method; step S2: based on a grouting event, collecting associated traceability information in a batch manner through the collection terminal, and forming a data fingerprint of the event to ensure the integrity and non-repudiation of the uplink data; step S3: performing block chain distributed accounting on the sleeve grouting traceability information and the spot check result; and step S4: tracking the sleeve grouting quality based on a unified traceability interface and a security access strategy. The system comprises a traceability standard module 1,a traceability information collection terminal 2, a quality traceability BIM module 3, a traceability information block chain accounting module 4, and a query traceability module 5. According to the method disclosed by the present invention, one of the bottlenecks of the standards, methods, tools, efficiency, safety, supervision and the like for tracking the sleeve grouting quality which restrictthe scale development of the industry in the new building industrialization process can be effectively solved.
