Abstract

The invention provides a duct piece assembling and grouting integrated machine for shield underground butt joint. The machine comprises a duct piece assembling machine, a first trolley, a second trolley, a grouting device, a power device and an anti-loosening device. Two ends of the first trolley are respectively connected with the second trolley and the duct piece assembling machine; the grouting device is arranged in the first trolley; the power device is arranged in the second trolley; and the duct piece assembling machine comprises an annular rotation device, an axial translation device, a radial lifting device and a grabbing device. By the adoption of the technical scheme, the problems of shield underground butt joint prefabricated duct piece assembling, synchronous grouting behind a wall, duct piece loosening and the like can be solved.

Description

technical field [0001] The invention relates to the field of shield machines, in particular to an integrated segment assembly and grouting machine for underground butt joint of shield machines. Background technique [0002] Under the conditions of large span, short construction period and complex geological conditions, the shield underground docking technology of "propelling in opposite directions, underground docking, and shell disintegration" has become a new development trend. At present, the secondary lining of the butt joint of shield tunneling mainly has two forms: cast-in-situ segment and prefabricated segment. In contrast, the secondary lining form of prefabricated segments has better anti-seepage performance, shorter construction period, and less labor costs. However, after the shell of the shield machine was discarded and disassembled, the prefabricated segments at the position of the main body of the shield machine and the docking section could not be used for se...
