Abstract

The invention discloses a prestressed concrete pipe pile curing device which comprises a curing pool, a steam generator, a preheating box and a cooling water tank. A sealing cover is arranged at the upper end of the curing pool, an air outlet of the steam generator is connected with a steam pipe, and the steam pipe communicates with the interior of the curing pool through an annular spraying mechanism. A water inlet of the steam generator is connected with a steam water pumping pipe, the steam water pumping pipe communicates with the interior of the preheating box, and a heat recovery mechanism is arranged in the preheating box. The prestressed concrete pipe pile curing device has the advantages that by arranging a surrounding pipe, hot steam generated by the steam generator is transferred into the surrounding pipe through the steam pipe, then sprayed into the curing pool through steam spraying pipes and rapidly diffused for heat transfer in water flow in the curing pool, so that the temperature in the curing pool is stably increased, the steam and water are combined to transfer heat so that local overheating caused by direct impact of steam can be avoided, heat dispersion is relatively uniform, and curing of a concrete pipe pile can be better achieved.

Description

technical field [0001] The invention relates to the technical field of concrete pipe pile maintenance, in particular to a prestressed concrete pipe pile maintenance device. Background technique [0002] With the improvement of the importance of modern buildings and the continuous increase of building height, the requirements for the bearing capacity of the foundation of the building are gradually increasing. In order to make the natural foundation meet the requirements of the bearing capacity of the upper building, pile drivers are generally used in foundation engineering now. The prestressed concrete pipe pile is pressed into the ground to become a foundation pile, and the building is built on the treated foundation to improve the bearing capacity of the foundation, so the quality of the prestressed concrete pipe pile is extremely critical; [0003] At present, the maintenance of concrete pipe piles usually adopts two curing processes, one is atmospheric pressure steam curi...
