Spiral wet type gas holder double-upside-down construction method
The invention relates to a double-upside-down construction method for a spiral wet-type gas holder. The whole construction sequence is that upside-down construction is carried out from inside to outside, and upside-down construction is carried out on a water tank wall plate and all stages of tower sections from top to bottom. During construction from inside to outside, operation space is large, construction efficiency is high in cooperation with a forklift loader, high-altitude operation can be reduced through construction from top to bottom, and safety and high efficiency are achieved. During construction of tower sections and water tank wall plates, a derrick-free electric hoist is adopted for lifting, and during construction of a bell jar, a center lifting rod is adopted for assisting in lifting for construction. The problem that the construction operation space is limited is solved, the use of hoisting machinery is reduced, the construction cost is reduced, and the installation efficiency is improved. The method is particularly suitable for construction and installation of spiral wet gas holders and non-standard storage tanks.
本发明涉及一种螺旋湿式气柜双倒装法施工方法，整体施工顺序为先里后外“倒装法”施工，水槽壁板和各级塔节先上后下“倒装法”施工。先里后外施工时作业空间大，配合叉装机施工效率高，先上后下施工可减少高空作业，安全高效。塔节、水槽壁板施工时采用了无抱杆电动葫芦提升，钟罩施工时采用了中心提升杆辅助起吊的方法进行施工。本发明克服了施工作业空间受限的问题，减少了吊装机械的使用，降低了施工成本，提高安装效率。本发明特别适用于螺旋湿式气柜、非标储罐施工安装。
