Problems solved by technology

The current maintenance process has the following defects: a. The residual steam of the autoclave and the discharged condensed water cannot be recycled, and the heat loss is large
The amount of condensed water discharged from each autoclave is about 10 tons each time, which wastes a lot of water resources and cannot be reused; b. After the steam culture pool is opened in summer, a large amount of hot air cannot be discharged, causing workshop work The ambient temperature is high, which affects the normal work and health of workers; c. The maintenance cost of pipe piles increases
The defects in the current maintenance process greatly affect the benefits of the enterprise. The economic benefits of the enterprise can be improved through the improvement of the maintenance process, which is consistent with the environmental protection production and energy-saving production process advocated by the state.

Abstract

The invention relates to a pipe pile water curing method. In the method, a water storage tank is arranged, and condensate water and residual steam in a still kettle are guided into the water storage tank; a pipe pile is placed in a steaming and curing pool, the condensate water in the water storage tank is guided into the steaming and curing pool, and the residual steam in water storage tank is guided into the steaming and curing pool; and steaming and curing the pipe pile in the steaming pool for 4-5 hours at 80-90 DEG C. The curing device comprises the steaming and curing pool, the water storage tank and the still kettle, wherein the steaming and curing pool is provided with a water-steam port; the water storage tank is provided with a residual steam outlet, a residual steam inlet, a condensate water outlet and a condensate water inlet; and the still kettle is provided with a steam inlet and a steam outlet. A condensate channel is arranged between the water-steam port of the steaming pool and the condensate water outlet of the water storage tank, and a steam channel is arranged between the water-steam port of the steaming pool and the residual steam outlet of the water storage tank. The condensate water inlet of the water storage tank is communicated with the condensate water outlet of the still kettle through a third electric control valve and a pipeline, and the steam inlet of the water storage tank is communicated with the steam outlet of the still kettle through a second steam valve and a pipeline.

Description

technical field [0001] The invention relates to a maintenance technology for concrete foundation pile engineering in the production process according to production requirements in the construction field, in particular to a water maintenance method and a water maintenance device for pretensioned prestressed concrete pipe piles after centrifugation. Background technique [0002] With the increasing importance of modern buildings and the continuous increase in building height. Higher requirements are put forward for the bearing capacity of the foundation. The natural foundation can no longer bear the load from the upper building, so the natural foundation is used, and there is a way to deal with it, that is, to use reinforced concrete as the foundation of the foundation Pile, the pile is pressed into the ground with a pile driver to become a foundation pile, and the upper part of the foundation pile bears the building. my country has stipulated corresponding standards for the ...
