Construction method of fragmental combined arc steel structure tank wall of large-sized concentration tank
The invention relates to a construction method of a fragmental combined arc steel structure tank wall of a large-sized concentration tank. The construction method comprises the following steps: step I, machining a fragmental arc steel tank wall in a factory according to a design drawing, and transporting the machined fragmental arc steel tank wall to a site; step II, on site casting a concrete foundation ring beam at one second of a lower height of the on-site constructed concentration tank steel structural tank wall; step III, hoisting arc steel structure tank wall fragments with pre-machined soleplate anchoring reinforcing steel bars onto the foundation ring beam, wherein in order to guarantee the accurate positioning of the tank wall and eliminate the subsequent installation errors of pipelines, a hoisted first fragment of the tank wall is a steel tank wall connected to an external overflow pipeline; step IV, sequentially installing, adjusting and welding adjacent steel tank walls to form a whole body, until a last fragment of the arc steel structure tank wall is assembled and welded; and step V, according to the installation progress of the steel tank wall, completing the casting construction of concrete of the one second of upper height of the foundation ring beam.
