Construction process of freeze-thaw-resistant, anti-seepage and anti-crack concrete
The invention discloses a construction process of freeze-thaw-resistant, anti-seepage and anti-crack concrete, and relates to the technical field of concrete construction. The method comprises the steps that a steel pipe body is vertically installed in a foundation pit, and the steel pipe body is sleeved with a formwork pile casing; a vibrating mechanism is placed between the first pouring cavity and the second pouring cavity, and upward movement of the vibrating mechanism is achieved through a lifting rope; when pouring starts, the lifting rope is in a straightened state, and when the vibrating mechanism is jacked by concrete grout, the lifting rope is loosened, so that a pressure signal on the pressure sensor disappears; after feeding is paused, the first vibrator and the second vibrator are started at the same time to start vibrating operation; and after vibration is completed, the vibration mechanism is lifted to the next pouring layer to continue pouring and vibration. By means of the construction mode of layered pouring and vibrating, the concrete vibrating effect is greatly improved, and then the construction quality of the whole concrete-filled steel tubular column is guaranteed.
本发明公开了一种抗冻融抗渗抗裂混凝土的施工工艺，涉及混凝土施工技术领域。本发明包括将钢管本体竖立安装在基坑中，并将模板护筒套设在钢管本体外侧；将振捣机构放置到第一浇筑腔和第二浇筑腔之间，并通过提升绳索实现振捣机构的上移运动；浇筑开始时提升绳索处于绷直状态，振捣机构受到混凝土浆上顶时提升绳索松弛使得压力传感器上的压力信号消失；暂停进料后，第一振捣器和第二振捣器同时启动开始振捣作业；振捣完成后振捣机构上提至下一浇筑层继续浇筑振捣。本发明通过分层浇筑和振捣的施工方式大大增加了混凝土的振捣效果，进而保证整个钢管混凝土柱的施工质量。
