The invention relates to the technical field of round bin
building construction, in particular to an aluminum
oxide bin upside-down construction method. S1, measuring and positioning the top surface of the completed foundation; and S2, the annular bottom plate is installed and fixed to the top face of the foundation. And S3, a center cylinder temporary fixing support is arranged on the top face of the foundation. And S4, the first circle of wall plates are assembled and fixed. And S5, assembling of the
silo top structure is completed. And S6, a plurality of hydraulic jacking devices are evenly distributed around the inner circumference of the foundation. And S7, the hydraulic jacking device is operated to synchronously jack the first circle of
wall plate. And S8, the next circle of wall plates are assembled and welded in the new assembling space. And S9, the hydraulic jacking device is operated to enable the supporting block to descend to the bottom, and a bracket is welded to the lower portion of the next circle of
wall plate. And S10, the steps of jacking,
assembly welding, supporting block descending and bracket
welding are repeated. According to the construction method, the construction sequence of firstly assembling the warehouse top, then jacking the warehouse top circle by circle and inversely installing the wall plates is adopted, so that the
safety risk caused by erecting a high-altitude
scaffold in a traditional forward installation method is effectively avoided.
