METHOD OF CONSTRUCTION USING MULTI-CAGE MINE HOIST OF HEIGHT REINFORCED CONCRETE PIPES WITH LARGE THICKNESS OF LINING WITH SMALL OUTLET DIAMETER AND LARGE RATIO OF OUTLET DIAMETER TO DIAMETER IN BASE Russian patent published in 2016 - IPC E04H12/28

Abstract RU 2574226 C1

FIELD: construction.

SUBSTANCE: pipe construction is started from erection of a pipe shaft and installation of lining from one installation of the device for lifting of a working site, at the same time the sequence of pipe shaft concreting and lining installation is performed in two possible versions.

EFFECT: expanded range of typical sizes of constructed pipes to the possibility of their construction with larger lining thickness at small outlet diameter and with large ratio of diameter in a pipe base to outlet diameter with reduced material intensity, prime cost and increased efficiency.
