Description

Technical Field

[0001] This utility model relates to the field of precast pipe pile maintenance technology, specifically a maintenance device for producing precast pipe piles. Background Technology

[0002] Pipe piles are classified into post-tensioned prestressed pipe piles and pre-tensioned prestressed pipe piles, prestressed concrete pipe piles (PC pipe piles), prestressed concrete thin-walled pipe piles (PTC pipe piles), and high-strength prestressed concrete pipe piles (PHC pipe piles). Pre-tensioned prestressed pipe piles are hollow cylindrical slender precast concrete components made using pre-tensioning prestressing technology and centrifugal molding. They are mainly composed of a cylindrical pile body, end plates, and steel sleeves.

[0003] Concrete pipe piles require curing after production, typically for two days. During this period, it is important to avoid subjecting the pipe piles to drastic temperature changes or impacts, as these can affect the curing effect. Existing curing devices are designed as integrated units, which waste space and steam energy when used for shorter pipe piles, and are difficult to accommodate for longer pipe piles, thus affecting the practicality of the curing device.
