【Technical field】
It the utility model is related to a kind of tunnel, and in particular to a kind of major diameter one-tunnel two-tracks subway tunnel, belong to subway and apply
Work field of engineering technology.
【Background technology】
At present, normal dia shield tunnel can only arrange a row subway train, and subway up-downgoing train is needed by two shields
Structure tunnel is realized, and the spacing between two shield tunnels is at least 1 Bei Dong rivers rising in Ningxia and flowing into central Shaanxi.Therefore, conventional shield tunnel Subway Tunnel accounts for
With the larger underground space, for the condition that the underground space is narrow and small, conventional shield tunnel Subway Tunnel line arrangement is extremely difficult.
Therefore, in order to solve the above technical problems, a kind of major diameter one-tunnel two-tracks subway tunnel it is necessory to provide innovation,
To overcome the defect of the prior art.
【Utility model content】
To solve the above problems, the purpose of this utility model is that up-downgoing train can be arranged in same tunnel by providing one kind
Major diameter one-tunnel two-tracks subway tunnel in road.
To achieve the above object, the technical scheme that the utility model is taken is：A kind of major diameter one-tunnel two-tracks subway tunnel,
It includes tunnel body, bottom plate, mid-board, road bed board, track, evacuation platform, circuit pipeline and contact net；Wherein, it is described
Bottom slab concreting is in the intrinsic bottom in tunnel；The mid-board pours on bottom plate vertically；During the road bed board is horizontally set on
On partition wall and in tunnel body；The track is provided with two, and it is laid on road bed board；The evacuation platform is connected to railway roadbed
On plate, and between two tracks；The circuit pipeline is laid in the intrinsic side wall in tunnel；The contact net is installed on
The intrinsic top in tunnel, and positioned at the surface of track.
Major diameter one-tunnel two-tracks subway tunnel of the present utility model is further arranged to：The external diameter 10m of the tunnel body,
Internal diameter 9m.
Major diameter one-tunnel two-tracks subway tunnel of the present utility model is also configured to：The evacuation platform is Prefabricated block, with
Road bed board is connected；The road bed board is monolithic reinforced concrete structure.
Compared with prior art, the utility model has the advantages that：Major diameter one-tunnel two-tracks of the present utility model
Up-downgoing train is arranged in same tunnel by subway tunnel, can be reduced and be taken the underground space of about half, and easy for construction,
It is cost-effective.
