随着劳动力结构的变化,劳动力成本急剧提升,在劳动密集且繁重的土建施工领域尤为突出.因此近几年施工机械化程度也随之不断提高,以减少对劳动力的依赖程度.越来越多的成型模具被运用到工程中,达到了加快进度、提高质量及降低劳动力成本的目标.在火力发电厂的系统工程中,大型自然通风冷却塔是极其具代表性的构筑物之一.其人字柱为一空间双向倾斜圆形支柱,施工过程存在定位、支模困难以及劳动力需求大的特点.文中所提到的现浇钢模体系很好地解决了这一施工难点,其具有质量工厂化控制、程序化施工、低劳动力需求以及高人性化设施的特点.
With the change of labor force structure, the cost of labor has risen sharply, especially in the field of labor-intensive and heavy construction, so the degree of mechanization of construction has also been continuously raised in recent years to reduce the dependence on the labor force. Molding mold is applied to the project, has reached the goal of accelerating progress, improving quality and reducing labor costs in the thermal power plant systems engineering, large natural draft cooling tower is one of the most representative structures. It is a two-way tilted circular pillar in a space, and there are some problems in the construction process, such as the positioning, the difficulty of mold support and the large demand of labor force. The cast-in-situ steel mold system mentioned in the article solves this difficult problem well. , Programmatic construction, low labor requirements and the characteristics of highly humanized facilities.
