FIELD: construction.SUBSTANCE: invention relates to construction, specifically a method for lifting and holding vertical steel tanks. Lifting method comprises welding posts to wall of reservoir, inside tank welded to struts and ribs connecting inside peripheral sheets and vessel wall, cut seam welding central portion of bottom to plates, welded end to end to central part of bottom plate are welded stiffening ring, set under posts stand out sleepers and planks, which sets reference metal plates. Between plates and struts are mounted jacks which produce vertical lift and hold steel tank. Between jacks along perimeter of reservoir are additional supports of piles. Console is installed on additional support after lifting of reservoir to design mark. Each console support is brought under reservoir wall. On additional support is fixed fastening parts each console. Reservoir is installed through cantilever on additional support of piles. Jacks are removed and support metal plate, providing retention of vertical steel tank by means of supports on additional supports of piles.EFFECT: technical result is reducing length of construction time.7 cl, 6 dwg |
