With the rapid development of the traffic industry in China, the highway construction gradually extends to mountainous and hilly areas and is limited by terrain conditions, and the highway construction in the areas often needs to cross deep ditches, so that the construction of high pier bridges is increased day by day. In order to ensure sufficient support strength and longer service life, the pier is generally formed by pouring concrete, so that corrosion, permeation and deformation can be effectively prevented, and the safety of the bridge is guaranteed; however, maintenance is required for a certain period of time after the construction of the concrete structure is completed, and generally, the maintenance is required to be started 12 to 18 hours after the concrete of the pier is poured, and the maintenance time lasts about 3 to 4 weeks to ensure normal hardening and strength increase of the pier.
The maintenance method not only covers the pier which is constructed and molded with water, but also needs to carry out heating maintenance, constant temperature maintenance, cooling water spraying and the like under a wet state, and has the disadvantages of complicated process and long time consumption. The existing bridge pier concrete curing method usually adopts a spraying and sprinkling mode or a film covering mode to keep the bridge pier concrete moist, but because the absorption speed of the concrete to water is limited, the spraying and sprinkling mode is difficult to uniformly spray, so that not only is the water resource wasted, but also the impact force on the surface of the bridge pier is large, and the stripping and dissolving loss of surface slurry are easily caused; the film covering can save water consumption, has good water locking and moisturizing effects, but the film exposed outdoors is easily damaged, and the completeness and effectiveness of the covering are difficult to ensure.
The two methods can not realize adjustment and control of the curing temperature, can not perform steam curing on the poured concrete in time during high pier construction, and are not beneficial to effective hardening of the bridge high pier concrete in preset time.
