Background The energy-saving sleeper beam is used as a key transverse force transmission component in highway bridge engineering and is mainly used for supporting upper structural load and transmitting the upper structural load to a support, the performance of the energy-saving sleeper beam directly influences the bearing capacity and the service life of a highway bridge, along with the deep green manufacturing concept, the energy-saving sleeper beam replaces natural broken stone by mixing large-particle-size energy-saving materials such as recycled coarse aggregate, waste concrete broken aggregate, light aggregate and the like in concrete, so that the ore exploitation energy consumption and the cement consumption are greatly reduced, the recycling utilization of building solid wastes is effectively realized, and the carbon emission and the environmental pollution in the production process are remarkably reduced. However, the existing grouting equipment generally adopts a direct casting process, namely, concrete materials are injected into a mold at one time and then subjected to vibrating treatment, in the process, concrete is in a flowing state after entering the mold, and because the viscosity of slurry is lower, large-particle-size aggregates continuously settle under the action of gravity, internal aggregates are mutually extruded and meshed, and the full dispersion is difficult to realize. When the vibration medium is used, the aggregate is often sunk to form an initial skeleton structure, so that the phenomenon of large aggregate clusters appears in the middle or lower part of the sleeper beam, and the top of the die is in a segregation state of slurry enrichment and poor aggregate. The uncontrollable interlayer separation causes serious uneven distribution of aggregate in the die, excessive enrichment of aggregate in the bottom area and insufficient strength in the top area, finally, the mechanical property and durability of the formed sleeper beam are difficult to reach design standards, and the performance exertion and engineering application of the energy-saving material are restricted.
