Description

Technical Field

[0001] The present invention belongs to the technical field of steam curing of pipe piles, and particularly relates to an assembled ground pipe pile steam curing table. Background Art

[0002] PHC pipe piles, namely prestressed high-strength concrete pipe piles, are made by the pre-tensioned centrifugal forming process and steam cured at about 10 atmospheres (about 1.0 Mpa) and about 180 °C to form a hollow cylindrical concrete precast member. The standard section length is 10 m, the diameter ranges from 300 mm to 800 mm, and the concrete strength grade is ≥C80. In addition to the pipe piles with the standard section length, there are also non-standard pipe piles with different lengths, thicknesses, and shapes. The steam curing of pipe piles is mainly carried out in steam curing ponds. At the beginning of the factory building design, a certain number of steam curing ponds are excavated on the ground. After the pipe piles are lifted into the steam curing ponds by a crane, the steam curing pond covers are covered. The steam curing ponds are connected to a steam supply system to fill in steam at a certain temperature, and a certain steam pressure is maintained in the steam curing ponds. After steaming and curing for a certain period according to the installation design requirements, the steam curing steps of the pipe piles are completed. Traditional steam curing ponds need to be excavated on the ground in advance. The production of pipe piles is generally scheduled according to the order quantity. When it comes to peak demand seasons or enterprise scale expansion, the situation of pipe piles queuing for steam curing often occurs. The insufficient number of steam curing ponds seriously affects the production demand of pipe piles. Different from other equipment, the existing steam curing ponds cannot expand production capacity in time by purchasing equipment. Therefore, it is necessary to design an emergency use equipment for pipe pile steam curing that can be temporarily and quickly assembled as needed and meet the steam curing requirements of different types of pipe piles.
