摘要: 神木神信热电有限公司发电工程空冷塔创新性地采用双交叉钢管混凝土X斜支柱代替传统钢筋混凝土X斜支柱和
单交叉X斜支柱。针对双交叉钢管混凝土斜支柱高度高、吊装质量大、异形杆件多等特点,对构件制作、焊接、拼装、
现场吊装及混凝土浇筑等施工技术进行了总结分析,为类似项目积累了经验。

Abstract: The air cooling tower of the power generation project of ShenmuShenxin Thermal Power Co., Ltd. innovatively
adopts double cross concrete -filled steel tube X inclined strut to replace the traditional reinforced concrete X inclined
strut and single cross X inclined strut. In view of the characteristics of high height, large hoisting quality and many
special -shaped members of the double cross concrete filled steel tube inclined strut, the construction technologies such
as member fabrication, welding, assembly, on -site hoisting and concrete pouring are summarized and analyzed, which
has accumulated experience for similar projects.
