Description

Technical Field

[0001] The invention relates to the technical field of pouring equipment, in particular to equipment for rapidly and continuously pouring fast-hardening concrete. Background Art

[0002] Over the course of long-term use, airport runways inevitably experience broken and falling slabs, necessitating repairs or even complete replacements. Currently, repairs and replacements at airports often rely on a human-intensive approach, with large-scale machinery used for demolition, mixers for rapid-hardening concrete mixing, and manual pouring. This process presents challenges such as long mixing times, inconsistent mixing results, high labor requirements, material accumulation, and chaotic management, placing high demands on on-site management. Even the slightest inattention can lead to hardened material in the mixer. Therefore, specialized machinery for pouring rapid concrete is highly desirable to ensure swift completion of slab replacement and repair tasks.

[0003] Military airports also need to be repaired quickly after being damaged, and a special fast concrete pouring equipment is urgently needed to ensure the rapid recovery of the airport.

[0004] The strength and hardening time of commercial concrete cannot meet the requirements of on-site construction. Airport construction requires that the air traffic conditions be met 2 hours after the concrete is poured. This requires that the concrete setting time and strength must meet the requirements. It can only be mixed and constructed on-site.

[0005] Therefore, the present application provides a rapid and continuous pouring of fast-hardening concrete equipment to meet the needs. Summary of the Invention
