混凝土立柱自动水雾化喷雾养护研究及应用

Research and Application of Automatic Water Atomization Spray Curing for Concrete Columns

摘要: 针对目前混凝土立柱自然养护和加热养护存在的不足，设计开发了一种模块组合式设计的自动水雾化喷雾养护装置。基于水泥水化热产生导致的混凝土温度梯度发生规律，计算了系统的用水量。以佛山地铁2号线林岳车辆段TOD综合开发项目中的混凝土立柱为作业对象，详细介绍了该新型装备的结构构造、施工组织过程和应用特点，试验对比测试显示自动水雾化喷雾封闭养护能缩短养护周期。此新型装备的成功研制与应用，有效改善了混凝土立柱养护的施工速度和工艺水平，降低了施工病害的发生。

Abstract: In view of the shortcomings of natural maintenance and heating maintenance of concrete columns at present, a modular combined automatic spray atomization maintenance device is designed and developed. Based on the law of concrete temperature gradient caused by cement hydration heat, the water consumption of the system is calculated. Taking the concrete column in TOD comprehensive development project of Linyue depot of Foshan Metro Line 2 as the operation object, the structure, construction organization process and application characteristics of the new equipment are introduced in detail. The comparison test shows that the automatic water atomization spray curing can shorten the curing period. The successful development and application of this new equipment effectively improves the construction speed and technology level of concrete column maintenance, and reduces the occurrence of construction diseases.
