Abstract
The utility model provides a shield segment which comprises at least one lining ring, the lining rings are connected through longitudinal bolts, each lining ring comprises a top sealing block, at least one adjoined block and at least one standard block, and the top sealing block, the adjoined block and the standard block are connected through annular bolts. The shield segment can be used for a tunnel which is low in headroom requirement, like an electricity power tunnel or various municipal administration pipelines, and can be used for construction deviation correction or curve simulation.
Description
Technical field
The utility model relates to a kind of shield duct piece, by the piece that binds, adjacent block and calibrated bolck, is spliced.
Background technology
Shield method has become the main construction of domestic subterranean tunnel, has been widely used in the construction of underground railway, river-crossing tunnel.Domestic subway tunnel track clearance is diameter 5.2m, and the shield duct piece internal diameter mostly is 5.4m or 5.5m.And for Clearance requirement less tunnel, as electric power pipe trench etc., how its shield duct piece designs not yet report.

The technical problems to be solved in the utility model is to provide a kind of shield duct piece, tunnel that can be less for Clearance requirement, and as electric power tunnel and various municipal pipeline, and can construct correction or curve simulation, there is versatility.
For solving above technical problem, the utility model has adopted following technical scheme:
A kind of shield duct piece, comprise at least one Lining Ring, between described Lining Ring, with at least one longitudinal bolt, connect, described Lining Ring comprises the piece that binds, at least one adjacent block and at least one calibrated bolck, between the described piece that binds, adjacent block and calibrated bolck, with at least one hoop bolt, connects.
Described Lining Ring is standard Lining Ring, left-hand bend Lining Ring or right-hand bend Lining Ring.
The wedge shape amount of described left-hand bend Lining Ring and right-hand bend Lining Ring is 41mm.
Described longitudinal bolt is arranged on calibrated bolck and adjacent block.
The described piece that binds is set to one, and described adjacent block is set to two, and described calibrated bolck is set to three.
Described calibrated bolck is positioned at the bottom of shield machine, and connects successively, and described adjacent block is positioned at the two ends of calibrated bolck, and the described piece that binds is between adjacent block.
The described piece that binds is wedge.
Described hoop bolt is bent bolt.
The internal diameter of described Lining Ring is that 3.6m, thickness are that 250mm, width are 0.8～1.0m.
Adopt above technical scheme, the obtained beneficial effect of the utility model is: the utility model provides a kind of shield duct piece, tunnel that can be less for Clearance requirement, as electric power tunnel and various municipal pipeline, and can construct correction or curve simulation.
The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, technology of the present utility model is described in further detail:
The structure chart of the Lining Ring that Fig. 1 is the utility model shield duct piece;
The A that Fig. 2 is Fig. 1 is to view;
