APPLICATION multicellular mine hoists FOR HIGH-RISE BUILDING CONCRETE PIPE thicker lining With low output diameter and large ratio of the exit diameter to the diameter at the base

摘要

1. A method of applying a multicellular mine hoist for the construction of tall concrete lining pipes with large thickness, with a small output with a large diameter and outlet diameter ratio of the diameter of the base pipe comprising a pipe construction with the barrel multicellular mine hoist device for lifting the working platform covering shaft hoist outside, and this movable work platform apparatus with Multiple Feature Select formwork for concreting of the pipe barrel, wherein the barrel concreting and pipe combined with the gradual installation of a mine hoist installation and flexible communications; feeding the concrete mix is ​​carried cargo cage, through which rope blocks arranged on the lifting device the working platform, is directed to a winch situated at ground level; Heat insulating and lining works lead to the socket site, characterized in that the construction tubes is produced in two stages: the first stage concreted trunk pipe with simultaneous gradual increase mine hoist; in the second stage after concreting tube bore partial dismantling work platform and lowering of dismantled elements of a cargo stand zeroed, separated from the tent unit to lift working platform lifting mechanism, the lower beams of the tent mounted diverting pulleys needed later in the lining work, lifting mechanism is lowered by the hoist mine simultaneously partially dismantled mine hoist, namely dismantled rack girders and struts mine hoist is lowered them g Uzes stand at zero
