the joint is installed a plurality of stabilizer plates (25) on the gap of two bed plates (1) concatenation, and the bottom both ends below of stabilizer plate (25) all is connected with plug (23), and the top of bed plate (1) all is provided with a plurality of first jacks (22) that are used for plug (23) grafting in concatenation department, and wherein first jack (22) on bed plate (1) extend to the inside of connecting hole (24), and the top of extension board (21) is provided with a plurality of shrinkage pool that correspond with inside first jack (22) of connecting hole (24).

10. A method for hoisting a hollow column for subway construction according to claim 9, comprising the above hoisting device, and comprising the steps of:

step one: the two base plates (1) are spliced through the connecting holes (24) and the extension plates (21) to form a complete stable base body, and a push plate (18) or a clamping head (19) is arranged at the end part of the second telescopic column (10);

step two: when the hollow column body is hoisted, the hollow column body is hoisted and moved by using an external hoisting device until the bottom end of the hollow column body enters the inside of the perforation (2), and before the bottom end of the hollow column body enters the inside of the perforation (2), the bearing plates (9) move along the sliding grooves (3) towards the perforation (2), and a plurality of bearing plates (9) play a role in supporting the hollow column body at the lower part; pushing the outer wall of the hollow cylinder by utilizing a plurality of pushing plates (18) at the top of the stable seat body, adjusting the position of the hollow cylinder, separating the bottom of the hollow cylinder from the bearing plate (9) after the position of the hollow cylinder is adjusted, and returning the bearing plate (9) to the original position along the sliding groove (3); the hollow column body moves downwards under the drive of the hoisting and rotating device above until the bottom end of the hollow column body is finally in stable contact with a preset placement point; in the descending process of the hollow column body, a plurality of pushing plates (18) outside limit the hollow column body, and the hollow column body does not shake in the descending process;

step three: if the hollow column body of the reinforcement cage is hoisted, a clamping head (19) is adopted for operation when the position is adjusted and the hollow column body descends; the clamping head (19) is clamped on the steel bar of the hollow column body, and the hollow column body is pushed to adjust the position; when the hollow column descends, the top plate (5) is firstly moved upwards by using the first telescopic column (8), then the clamping head (19) clamps the steel bars, and when the hollow column descends, the first telescopic column (8) drives the top plate (5) to descend together with the hollow column; after the top plate (5) descends to the lowest part, the clamping head (19) releases the clamping of the steel bars, and the steel bars are clamped again after the top plate (5) returns to the upper part again, and the reciprocating cycle is sequentially carried out until the hollow cylinder descends and is placed at a preset position;

step four: if the hollow cylinder is placed on the stable seat body and needs to move for a long distance, and in order to avoid collision of the top by other objects during movement, the hollow cylinder to be moved is placed transversely, and a plurality of stable seat bodies are spliced; and the hollow cylinder is moved to a preset position by utilizing the plurality of stable seats to be matched with the lifting appliance above, and finally the hollow cylinder is lifted orderly and stably in the vertical lifting mode.
