Self-lifting type hydraulic synchronous jacking chimney construction method
The invention discloses a self-lifting type hydraulic synchronous jacking chimney construction method which comprises the following steps: S1, assembling a platform on site; s2, assembling a hydraulic synchronous jacking device; s3, assembling a vertical transportation system; s4, manufacturing a template; s5, the formwork is installed; the chimney is divided into a plurality of pouring layers in the height direction, the height of each pouring layer is the lifting height of the outer formwork, concrete is poured between the inner formwork and the outer formwork, after the concrete reaches the formwork removal strength, the outer formwork is lifted upwards to the next pouring layer through a chain block, then the jack is started, the platform is lifted, and the steps are repeated till the top of the formwork is poured, and the concrete is poured into the formwork. And chimney pouring is completed. According to the self-lifting type hydraulic synchronous jacking device, construction of the chimney is implemented, a bottom-up derrick is not erected in the chimney to serve as a support, and a steel pipe framework in the circumferential direction of a barrel serves as a supporting rod to lift the whole platform. The operation is more efficient and convenient, and the quality is safe and controllable.
本发明公开了一种自举式液压同步顶升烟囱施工方法，包括以下步骤，S1现场组装平台；S2：组装液压同步顶升装置；S3：装配垂直运输系统；S4：模板制作；S5：模板安装；S6：顶升：将烟囱沿高度方向划分为多个浇筑层，每个浇筑层的高度为外模板的提升高度，向内外模板之间浇筑砼，待砼达到拆模强度后再用倒链将外模步向上提升到下一个浇筑层，然后启动千斤顶，对平台进行提升，如此循环直到浇至模板顶部，完成烟囱浇筑。本发明则采用自举式液压同步顶升装置来实施烟囱的施工，在烟囱内部不搭设自下而上的井架来作为支撑，而是利用筒体圆周方向的钢管骨架作为支撑杆来提升整个平台。操作更加高效，便捷和质量安全可控。
