The invention belongs to the technical field of wind
tunnel construction methods, andparticularly relates to a construction method of an inner mold
support system for a super large wind tunnel
diffusion section.Theconstruction method of the inner mold
support system for the super large wind tunnel
diffusion sectioncomprises the following steps that A, an inner
steel cylinder formwork and a profile steel
structure support frameare structurally designed and subjected to consigned
machining; B, the inner
steel cylinder formwork and the profile steel
structure support frame are machined, pass an examination, and are transported to a construction site, a project department organizes material acceptance, and data such as the size,flatness, curvature, and chord length of each formwork are rechecked one by one according to two-dimensional code data to ensure that the design requirements are met; C, on-site positioning and line dropping of each cross section of the inner
steel cylinder formwork are conducted; and D, positioning and mounting of the inner steel cylinder formwork and the profile steel
structure support frame are conducted.According to the construction method of the inner mold
support system for the super large wind tunnel
diffusion section, the construction problem of the super large wind tunnel circular-to-square diffusion section iseffectively solved,with the method, the internal mold support
system which meets the construction accuracy requirements can be built, and smooth completion of the construction is ensured.
