Description
Technical Field
The utility model belongs to the field of bridge concrete structure reinforcement and repair. More particularly, the utility model relates to an intelligent high-temperature moisturizing curing device applied to a concrete structure.
Background
After the bridge concrete pier column is impacted and damaged or has rust, cracking and cracking diseases, repairing and reinforcing the bridge concrete pier column are needed, the damaged part of the structure is usually chiseled out in the repairing and reinforcing process, and then concrete is poured or cement mortar is smeared on the concrete pier column. The conventional concrete or cement mortar repairing material has the problems of low strength, easiness in cracking, weaker repairing and poor durability, and the ultra-high performance concrete (UHPC) has the characteristics of high strength, high toughness and high durability, so that the repairing material is an ideal repairing and reinforcing material for a concrete structure. The acquisition of the excellent performance of UHPC is directly related to the high-standard curing condition, and the UHPC is prepared by mixing a mineral fine admixture and a high-efficiency water reducing agent with a low water-gel ratio and a sufficient amount, but the UHPC is easy to cause shrinkage cracking due to self-drying, and strict moisture-preserving curing is required after pouring molding; in order to accelerate the hydration reaction of the active admixture in UHPC and improve the internal microstructure, maintenance is required by heating to manufacture a high-temperature environment. From the article of the ultra-high performance concrete research review, we also know that the high-temperature and pressure curing system is an important means for obtaining high performance by UHPC, the higher the temperature and the longer the time, the more silica fume is reacted, the more compact the internal structure is, and compared with the heat curing at 90 ℃, the UHPC test block under the standard curing condition at 20 ℃, the compression strength is reduced by 20%, the bending strength is reduced by 10% and the breaking energy is reduced by 15%. Comparative experiments are carried out on 4 curing modes of steam curing, delayed steam curing and cooling steam curing and conventional curing, and the results show that the steam curing has the greatest influence on the wood quality, and the delayed steam curing and cooling steam curing have smaller influence on the wood quality. However, steam or autoclaved curing brings difficulty to construction and also increases the preparation cost. Thus, the harsh maintenance conditions required for UHPC limit its application in reinforced solid engineering. When the bridge pier concrete structure is repaired, reinforced and cured by adopting conventional concrete, the requirement on temperature is low, and the bridge pier concrete structure is subjected to moisture maintenance at 20-40 ℃, if the bridge pier concrete structure is repaired and reinforced by adopting UHPC material, the bridge pier concrete structure is required to be cured at the high temperature of 90 ℃ and moisture maintenance, otherwise, the excellent performance of UHPC is not fully realized. In the disclosed patent CN215926816U concrete structure intelligent moisture curing device, only curing humidity in the range of 80% -95% can be provided for newly poured repair concrete, and high-temperature curing cannot be provided. In addition, for the winter reinforcement construction of concrete structure, the maintenance measure of heat preservation and moisture preservation is especially important. Therefore, in order to solve the maintenance difficulty in repairing and reinforcing the pier concrete structure by adopting UHPC, and meet the high-standard maintenance condition requirement, a device capable of providing humidifying and heating maintenance conditions for repairing and reinforcing the pier concrete structure is needed.
