The invention discloses CRTS III type plate self-compacting concrete pouring construction equipment which comprises a compartment, a cab and a lorry-mounted crane, wherein the compartment comprises a first compartment and a second compartment; the first compartment is hinged with the second compartment; the cab is arranged at the front end of the compartment; the lorry-mounted crane is arranged at the tail end of the compartment; a power system, a hydraulic system and a material storage space are arranged in the second compartment; a dry material tonnage-loading small crane is arranged at the top of the material storage space; a dry material storage hopper is arranged at a position, close to the first compartment, in the material storage space; an auxiliary material box, a dry material metering hopper, a second conveyer, a stirring system, a finished product material transferring hopper and a finished product material storage box are arranged in the first compartment. The CRTS III type plate self-compacting concrete pouring construction equipment integrates material feeding, stirring, pouring and other functions; due to the adoption of self-compacting concrete for on-site production, good procedure connection is realized, the on-site civilized construction figure is good, and the construction efficiency and the construction quality of the self-compacting concrete pouring construction are improved; the number of assorted equipment for self-compacting concrete pouring construction is greatly reduced, and the engineering construction cost is reduced.
