Embodiment 1
[0049] The non-standard equipment fire water tank involved in this embodiment has an inner diameter of 20m, a height of 22m, and an effective volume of V=5662m. The specific construction process is as follows:
[0050] S1. Steel pipe 1 and casing 3 of the machining center. The central steel pipe 1 uses a φ219*6.3mm steel pipe, and a φ27 pair of limit holes 8 are opened every 1800mm on the central steel pipe 1 (the limit pin shaft 5 uses a φ25mm round steel), and the bearing 2 is inserted from one end and φ273 is welded outside the bearing 2. *12.5 Sleeve 3 is used to weld the external platform, and the supporting plate 15 (20mm thick) is welded under the sleeve 3.
[0051] S2. Fixing the central steel pipe 1 and the casing 3. Weld a circular guard plate (20mm thick) in the center of the bottom plate and top plate of the storage tank respectively, weld the processed central steel pipe 1 at the center position, and use theodolite to detect the verticality of the central steel ...
