Description

Technical Field

[0001] This invention relates to the field of prefabricated pavement technology, specifically to a dust-free chemical plant prefabricated temporary PC pavement panel and its installation method. Background Technology

[0002] Currently, there is limited research both domestically and internationally on prefabricated temporary sites and construction access roads. Some research focuses primarily on prefabricated concrete pavements, and most of this work remains in the research phase. This is mainly due to issues with prefabrication and transportation of prefabricated pavement panels, resulting in high costs, inconvenient disassembly and transportation, and low reuse rates. Therefore, most construction sites in China still use cast-in-place concrete (or reinforced concrete) as temporary sites or access roads. Cast-in-place sites suffer from drawbacks such as long construction cycles, low efficiency, high costs, and difficult maintenance. Very few existing sites and temporary access roads can be used permanently using a "temporary-permanent combination" approach; most require subsequent demolition, removal, and repaving, severely impacting project progress and hindering cost control. Furthermore, damaged sites frequently occur during use, and reinforced concrete structures are difficult to repair. Summary of the Invention
