在热电厂工程中,经常会看到双曲线形冷却塔,支撑上面整个风筒的是人字柱。这些一对对的人字柱都是斜柱,截面常见的有正四边形、圆形和正八边形等。保证这些斜柱的混凝土施工质量非常关键,稍有不慎,就会造成烂根、孔洞、露筋、蜂窝、麻面等质量缺陷。在工程实践中我们采取了以下 In thermal power plant projects, hyperbolic cooling towers are often seen, and the entire fan cylinder is supported by a herringbone column. These paired pairs of columns are all slanted columns. The cross-sections are usually regular quadrilaterals, circles, and regular octagons. To ensure that the quality of the concrete construction of these inclined columns is critical, if there is any carelessness, it will cause quality defects such as rotted roots, holes, exposed tendons, honeycombs, and pits. In engineering practice we have taken the following
