METHOD AND DEVICE FOR CYLINDRICAL RESERVOIR ERECTION BY TOP-DOWN CONSTRUCTION METHOD Russian patent published in 2005 - IPC

FIELD: building, particularly liquid and gas reservoir building.

SUBSTANCE: method involves forming building site at reservoir base, wherein building site is provided with fixed rotary jib crane and unloading racks and is adapted for stacking sheet and other blanks; building foundation by outer gantries of lifting means near reservoir foundation; moving sheets for reservoir wall belts by means of hoists displaced along monorails suspended by consoles of lifting means gantries along reservoir perimeter, wherein sheets are conveyed to hoist areas by narrow-track trolley; mounting reservoir wall belts, wherein all belts besides lower one are mounted on main boom of lifting means with the use of checkpoints and cross-arms which direct the belts along inner reservoir radius, lower belt is mounted on reservoir bottom; mounting plates on the first upper reservoir wall belt after lifting two belts having fixed roof, inventory scaffolds installed on consoles of outer and inner lifting means gantries along reservoir perimeter with the use of hoists. Lifting means gantries are arranged in pairs on common frame inside and outside the reservoirs. Each gantry includes pusher and two posts formed as paired ratchet bars and coupled one to another by upper tie. Upper pusher end extends through upper tie and is fixed by guiding finger to prevent rotation thereof around vertical axis. Each gantry is provided with slider. Main booms are suspended to sliders of inner and outer gantries so that main boom positions may be adjusted in vertical plane. Cross-arms having curvature radius equal to inner radius of reservoir wall are installed on main booms so that cross-arm positions may be adjusted in horizontal plane. Length -adjustable consoles are connected to upper tie and provided with bearing rollers, monorails for hoist movement along reservoir perimeter are suspended to central part.

EFFECT: increased reservoir stability during erection thereof.
