在现代工业建筑安装工程中,大型吊装机械显示了无法类比的优越性。特别对于大型钢筋混凝土预制构件的安装,更是一般起重机械所望尘莫及的,然而,对于体积小、宜量轻、数量多的小型钢筋混凝土预制构件的安装,一般机械土法综合吊装法,仍具有其优越性。我们在沁阳电厂冷却塔安装工程中,创造了一套技术经济上合理的土法综合吊装法,成功地完成了淋水支柱、小梁及配水槽的安装。一、工程概况沁阳电厂二期扩建工程冷却塔为两座600平方米自然通风双曲线冷却塔。塔身最大半径16.4米,塔顶自然标高42米。淋水装置系存于风筒内部的装配式钢筋混凝土结构,包括淋水支柱、配水槽及小梁等。以钢筋混凝土预制构件作骨架,安设网格板、喷嘴
In modern industrial building installation engineering, large hoisting machinery shows the superiority that cannot be compared. Especially for the installation of large-scale reinforced concrete prefabricated components, it is far more difficult than ordinary lifting machinery. However, for the installation of small-scale, light-weight, large-quantitative small-scale reinforced concrete prefabricated components, general mechanical soil method is still Has its advantages. During the installation of the cooling towers in the Leiyang Power Plant, we created a technically and economically reasonable method for the overall lifting of the soil and successfully completed the installation of the shower pillars, trabecules and distribution tanks. I. Project Overview The cooling tower of Phase II expansion project of Puyang Power Plant consists of two 600 m2 naturally ventilated hyperbolic cooling towers. The maximum radius of the tower body is 16.4 meters, and the top of the tower is 42 meters above sea level. The watering device is a prefabricated reinforced concrete structure stored inside a fan cylinder, including a shower pillar, a gutter, and a trabecular beam. Using reinforced concrete prefabricated components as skeletons, installing grid plates and nozzles
