SUBSTANCE: pipe is constructed in two stages: at the first stage they concrete the pipe shaft with simultaneous gradual growth of a mine hoist. At the second stage upon completion of pipe shaft concreting, partial dismantling of a working site and lowering of dismantled elements in a cargo basket to zero elevation, they separate a lifting mechanism from a tent of a device for working site lifting, on the lower beams of the tent they install diverting blocks necessary further during lining works, the lifting mechanism is lowered along the mine hoist, simultaneously they partially dismantle the mine hoist. Two cells are left: one for lifting of the cargo basket, the other one for movement of fitters along a service ladder, partial dismantling of the mine hoist and lowering of the lifting mechanism is carried out to the level of the pipe height half, further they continue lowering the lifting mechanism without dismantling of the mine hoist to zero elevation, from which they start lining works. At the distance equal to lining thickness, from the inner surface of the pipe shaft they install shields of internal sheathing and start lifting the lifting device with the suspended lining site, repeating operations of shields installation, their detachment, setting of lining and periodical lifting of the site to the level of the fully assembled mine hoist, which corresponds to installation of the lining to the half of the pipe height, at this height they disconnect the lining site from the lifting mechanism frame and suspend it on the ropes that stretch towards the diverting blocks, enveloping them and fixed on the support-shift frame of the lifting mechanism. Three rows of shields are used, besides, the lower one is the support one for the two above, and as they lay another tier of lining, the shields are shifted, and the lower one becomes the upper one. Blocks of the cargo basket are installed on the mine hoist, the lifting mechanism is lifted along a fully mounted part of the mine hoist, thus they lower the lining site downwards, from there they perform full dismantling of the partially dismantled mine hoist, and the lifting mechanism is moved to the top of the assembled mine hoist, at the same time the rope is disconnected from the lining site, which is connected to the support-shift frame of the lifting mechanism, the blocks of the cargo basket are installed on the support-shift frame, the ropes are removed from diverting blocks, and with the help of, for instance, attached hemp ropes they are lowered onto the support-shift frame of the lifting mechanism, the lifting mechanism is lowered along the assembled part of the mine shaft, which is gradually dismantled, and the dismantled elements are lowered in the cargo basket to zero elevation, at zero elevation they dismantle the lifting mechanism, via process openings at the bottom of the pipe shaft they remove the dismantled elements outside.

EFFECT: expanded range of dimension types of constructed pipes towards the possibility of their construction with higher lining thickness, with small outlet diameter and with higher ratio of the outlet diameter to the diameter in the base with lower material intensity, labour intensiveness, prime cost and increased efficiency.

Upon completion of pipe shaft concreting the blocks of the cargo cage are rested against a shaft hoist, the working site is dismantled, elements of the tent and device for working site lifting, dimensions of which prevent passage of the device in the assembled form via the outlet diameter of the pipe shaft cut, the dismantled elements are lowered in the cargo cage along the shaft hoist. The device for lifting of the working site is lowered along the shaft hoist down, from which angular stands are dismantled with adjacent crossbars and struts, and flexible links to zero elevation, in partially dismantled angular cells of the shaft hoist they install diagonal crossbars for increasing its stiffness; at the bottom the device is fully dismantled. Movement of the self-lifting device is carried out by four specified hoists as ropes are wound or unwound from hoist drums, at the same time to increase weight-lifting capacity of hoists, the rope of each hoist is directed to the assembly block and is returned to the self-lifting device on the frame. The assembly block with its hook with a latch is suspended onto a ring of a double-branch chain sling, each branch of which is fixed on a quick-detachable yoke, installed on the coupling of the shaft hoist stand. A lining site is suspended to the self-lifting device, from which heat insulation, lining works are performed, as well as anti-corrosion protection. When arranging another layer of lining, during lifting of the self-lifting device they restore flexible links and angular stands, and adjacent crossbars and struts under the lining site. When lowering the device, to prepare for arrangement of another layer under the lining site they dismantle angular stands, crossbars, struts and flexible links. After lining the blocks of the cargo cage are fixed on the cut of the pipe shaft. Cells of the shaft hoist are covered by shields installed onto crossbars, from which it is dismantled to zero elevation. Afterwards the self-lifting device is dismantled.
