Abstract:
1. A high temperature high pressure underwater curing apparatus for concrete molding products in high temperature high pressure curing water sealed in a pressure resistant vessel comprising a plurality of openable/closable pressure resistant vessels for containing concrete molding products, each of the pressure resistance vessels comprising: a curing water supply device for supplying water or warmed water as curing water to the inside of the vessel; a pressurized air supply device for supplying pressurized air to the inside of the vessel thereby pressurizing the inside curing water; a heater for heating the curing water supplied to the inside of the vessel and maintaining the same at a predetermined temperature; and a deaeration valve disposed to an upper portion of the vessel for opening the inside to atmospheric air, wherein a transfer pipe is disposed to a lower portion of each vessel being connected to an optional portion of other pressure resistant vessel for delivering curing water in communication with other pressure resistant vessel by way of an ON/OFF valve, a transfer pipe is disposed to the optional portion of each vessel being connected to the lower portion of other pressure resistant vessel and receiving curing water in communication with the other pressure resistant vessel by way of an ON/OFF valve, and the respective pressure resistant vessels are connected by the two transfer pipes so as to form a circulation channel to each other.
