机力冷却塔是石油化工厂应用非常广泛的一种水工构筑物。根据冷却水量的大小可分单列式和双列式两种布置。从结构组成看,一般包括框架梁柱、围护墙板、风筒、顶板、水池、填料六大部分。框架梁柱有现浇整体式和预制装配式两种,以预制装配式结构采用较多。围护墙板有预应力槽瓦、槽瓦、石棉瓦、预应力肋形板、钢筋混凝土槽
Mechanical cooling towers are a wide range of hydraulic structures used in petrochemical plants. According to the size of the cooling water can be divided into two kinds of arrangement of single and double. From the perspective of structural composition, it generally includes six parts: frame beam column, enclosure wall plate, air cylinder, roof plate, pool, and packing. There are two kinds of cast-in-place frame and prefabricated frame beams, and more prefabricated structures are used. The retaining wall panels are prestressed slot tiles, slot tiles, asbestos tiles, prestressed ribbed plates, reinforced concrete channels
