Description

A curing means for concrete product

Technical Field

The utility model relates to a concrete construction technical field, in particular to a curing means for concrete product.

Background

The prestressed concrete pipe pile is widely applied to civil engineering such as building structures, bridge structures and the like due to the advantages of high single-pile bearing capacity, convenience in construction and the like, and can be divided into post-tensioning prestressed pipe piles and pre-tensioning prestressed pipe piles. The pre-tensioning prestressed pipe pile is a hollow cylindrical elongated concrete prefabricated member made up by adopting pre-tensioning prestressed process and centrifugal forming method, mainly formed from cylindrical pile body, end plate and steel ferrule. The post-tensioning method prestressed pipe pile is characterized in that prestressing force is applied through holes reserved in the pipe pile after concrete in the pipe pile is initially set.

During the production process of the tubular pile, a lower die of the tubular pile is fixed, then concrete is poured, then the lower die is hoisted and installed on the tubular pile and fixed and sealed by bolts, then the whole tubular pile is rotated at a high speed by a centrifugal machine, the concrete is centrifugally formed in the tubular pile and then becomes a hollow tubular cylinder, and then heating maintenance is carried out. The heating maintenance is a very important production process link, and the quality of the effect not only directly affects the demolding strength of the tubular pile concrete, but also affects the final strength of the tubular pile concrete. The best effect of curing the tubular pile is that high-temperature and high-pressure water directly acts on concrete pouring, the action of water becomes active in a high-pressure and high-temperature environment, and the hydrothermal action further promotes the hydration reaction of cement and the recombination and maturation of crystal morphology, so that the concrete can be promoted to be rapidly condensed, and the strength can be improved. The steam curing process generally comprises four stages of standing still, heating, constant temperature and cooling, such as: standing for 30 minutes, heating to 8-10 ℃ 30min before the heating stage, heating to 16-22 ℃ every half hour, pressurizing and heating to 90-95 ℃, heating for 1.5 hours totally, keeping the temperature for 2 hours and 45 minutes, and keeping the whole steam curing time for 4 hours and 45 minutes.

The heating maintenance process adopted in the market at present is to place the whole centrifugally formed pipe piles into a maintenance pool, place 5-8 pipe piles in one maintenance pool, then cover a concrete cover plate, and finally spray high-temperature steam through spray pipes around the maintenance pool, so that steam pressure maintenance can be carried out, and the steam is supplied by a large-scale boiler in a unified manner. The heating maintenance process mainly has the following problems:

1) the maintenance pool adopts a large boiler to supply steam uniformly, once the equipment is started, a large amount of energy needs to be consumed continuously, and steam meeting the temperature and pressure requirements can be produced;

2) the maintenance pool is only used for simply spraying high-temperature steam through the surrounding spray pipes to heat the steel mould on the outer layer of the tubular pile, then transferring heat to the concrete tubular pile inside the steel mould for maintenance, most of the steam is emitted into the air, so that heat loss and waste are caused, and the temperature and the pressure acting on the tubular pile cannot be accurately controlled;

3) due to the obstruction of the steel mould, steam and water sprayed out of a spray pipe of the curing pool cannot directly act on the concrete pipe pile, and the effects of pressurization and water curing cannot be generated;

4) in addition, the concrete pipe pile has the defects of too long maintenance time, cracks of the pipe pile and the like seriously due to fast temperature rise at the outer part, slow temperature rise at the inner part and uneven heating of the pipe pile.

The defects exist not only in the manufacturing and curing process of the concrete pipe pile, but also in the manufacturing and curing process of other concrete products.
