The jacking device and the jacking method are used for jacking the shield tunneling machine, the shield tunneling machine comprises a front shield, a middle shield and a shield tail, and the front shield, the middle shield and the shield tail are connected in sequence; the jacking device comprises four jacking devices, a plurality of stacking seats and a plurality of stacking layers, every two jacking devices are symmetrically arranged on the two sides of the bottom end of a front shield and the two sides of the bottom end of a middle shield, the top end of each jacking device abuts against and is matched with the front shield and the middle shield, and the stacking seats are arranged at the bottom end of each jacking device; the plurality of superposed layers are arranged up and down, and are arranged between the shield tunneling machine and the ground. The whole structure is compact, arrangement is reasonable, the jacking devices extend to lift the front shield and the middle shield, the stacking layers are laid below the front shield, the middle shield and the shield tail, the jacking devices are shortened, the stacking bases are additionally arranged at the bottom ends of the jacking devices, the jacking devices extend again, and the like, so that the shield body is moved to the preset height.
本发明公开了一种盾构机顶升装置以及顶升方法,用于顶升盾构机,盾构机包括:依次相连的前盾、中盾以及盾尾;该顶升装置包括:四个顶升器、多个叠加座以及多个叠加层,每两个顶升器对称设置于前盾底端两侧、中盾底端两侧,且每个顶升器的顶端分别与前盾、中盾抵触配合,每个顶升器的底端分别设有叠加座;多个叠加层上下罗列,且多个叠加层设置于盾构机与地面之间。本发明整体结构紧凑、设置合理,其通过顶升器伸长将前盾、中盾举起,在前盾、中盾、盾尾下方铺设叠加层,顶升器缩短,在每个顶升器底端添加叠加座,顶升器再次伸长,以此类推,从而将盾体调动至预定高度。
