摘要 国内外传统混凝土筒仓减压锥通常为整体浇筑设计,现场通过搭设高大模支承体系现浇混凝土施工。为节省搭设脚手架及其他方面的成本,本工程两个生料库减压锥采用现场支模整体现浇施工与现场分片预制施工及吊装两种施工方法。对于预制施工,通过总结以往减压锥的施工经验,突破预制减压锥施工技术难点,从合理布置场地、绑扎浇筑、养护、选用机械、吊装就位等方面制定施工方案。结合预制锥体受力特性、现场吊装特点及浇筑特点,完成该施工工艺的技术突破及创新过程。最后通过对比两种减压锥施工方法,得出结论。

Abstract: Overall design, building formwork and cast-in-situ construction on site are adopted usually for traditional concrete silo decompression cone at home and abroad. In order to research saving the cost of formwork and other, two construction ways are adopted for decompression cone of the two raw meal silos of this project: cast-in-situ construction on site; precast concrete on site and lifting and installation. For precast construction, through summarizing the construction experience of previous decompression cone, breaking through the technical difficulties of decompression cone construction, we make construction plan from the follow sides: reasonable arrangement of the site, rebar tying, casting, maintenance, selection of machinery, hosting, etc. In combination with the characteristics of precast element, hosting and casting, the technical breakthrough and innovation process of the construction process are completed. At last, through two construction ways, we get the conclusion.
Key words:  decompression cone construction    prefabricated cone    lifting and installation    cost of construction
