Large-volume ultra-high-performance concrete thermal curing system and thermal curing process
The invention discloses a large-volume ultra-high performance concrete thermal curing system and a thermal curing process, and belongs to the technical field of bridges and related civil engineering, a thermal insulation shed is arranged on large-volume UHPC concrete and encloses the periphery, and a steam heating device is arranged on the ground around the large-volume UHPC concrete in the thermal insulation shed; a temperature adjusting device is arranged at the bottom of the large-volume UHPC concrete; the system provides a solution for uniformly heating and cooling the large-volume UHPC concrete in a front-back, up-down, left-right all-dimensional controllable temperature difference manner, and the temperature difference between a core part and a surface can be intelligently stabilized between 5 DEG C and 15 DEG C in the curing heating and cooling stages, so that the cracking risk of the large-volume UHPC concrete structure is greatly reduced, and the engineering quality is improved; meanwhile, due to the fact that the absolute temperature rise of the UHPC concrete structure is large generally and the traditional cooling time is long, the system can achieve rapid cooling through gradient constant-temperature water, and it can be ensured that the temperature difference between the inner surface and the outer surface is within a controllable set value. The construction period is shortened, and the project comprehensive cost is effectively reduced.
本发明公开了大体积超高性能混凝土热养护系统及热养护工艺，属于桥梁及相关土建技术领域，所述保温棚设置于大体积UHPC混凝土之上并围蔽四周，蒸汽升温装置布设于保温棚内的大体积UHPC混凝土四周地面，所述大体积UHPC混凝土的底部布设有温度调节装置；本系统提供了大体积UHPC混凝土前、后、上、下、左、右全方位可控温差均匀升温和降温的解决方案，并且可智能化实现芯部与表面温差在养护升温、降温阶段稳定在5‑15度之间，从而极大减少了大体积UHPC混凝土结构开裂风险，提升工程质量；同时，因大体UHPC混凝土结构绝对温升大，传统降温时间长，本系统采用递度恒温水可快速降温且可确保里表温差在可控设定值内。缩短了施工周期，有效降低项目综合成本。
