AI Technical Summary

Technical Problem

Existing frame vibratory beam pavers struggle to handle uneven material distribution and localized material accumulation during construction, and cannot automatically smooth out corner areas, resulting in low construction efficiency, reliance on manual experience for flatness, and a tendency for insufficient strength or surface defects.

Method used

It adopts an integrated mechanical scraper and servo drive system, combined with an arc-shaped baffle design, to achieve automated closed-loop adjustment of the concrete surface. The servo motor precisely controls the scraper lifting and lowering and the multi-stage telescopic cover auxiliary components, and works with cleaning fluid and electromagnet structure for automatic cleaning.

Benefits of technology

It achieves automated flatness adjustment of concrete surface, avoids water-cement ratio loss caused by manual backfilling, improves construction efficiency and automation level, ensures uniformity of paving layer and equipment durability, and significantly improves cleaning efficiency and equipment reliability.
