The surrounding rock excavated when the TBM advances is not exposed after being supported by the high-precision segment lining, so that the stability of the surrounding rock of the tunnel wall is maintained. The bean gravel can be subjected to auxiliary operations such as hydraulic filling, grouting, ventilation, power supply and the like, so that parallel construction can be implemented, and the space in the hole is fully utilized. And the duct piece is required to be transported through a duct piece lifting system during TBM construction. The duct piece lifting system mainly comprises a single-beam duct piece crane and a duct piece trolley. The pipe sheet is transported to the pipe sheet trolley by the pipe sheet crane, and then is transported to the position where the pipe sheet splicing machine can grasp by the pipe sheet trolley. 3 duct pieces can be placed on the duct piece trolley at a time. The traveling driving mode of the segment crane adopts a chain wheel and chain type, the traveling braking is reliable, and the maintenance is convenient.
When the section of jurisdiction handling, single section of jurisdiction weight reaches 5 tons, and the route of section of jurisdiction handling is at the key position that TBM section of jurisdiction was assembled, and the personnel is more, and the section of jurisdiction is because operating space is limited when transporting on the walking roof beam, and the section of jurisdiction rocks seriously, takes place the condition that section of jurisdiction hoist head breaks away from the hoist in the time of the construction, causes the section of jurisdiction to damage, causes very big potential safety hazard to personnel. At present, the pipe piece lifting appliance needs to be redesigned, so that the safety of the pipe piece lifting appliance is ensured in the lifting process, and personnel damage caused by falling of a lifting head due to overlarge shaking is avoided.
