Description
Technical field
The present invention relates to Tunnel Engineering technical fields, particularly, are related to a kind of for shield machine air pushing step device.
Background technique
With the development of the city, the construction of subway is more and more, and Urban Metro Construction is usually shallow-depth-excavation tunnel, often
The route that normal tunnel is passed through is city prosperity location, covers that building is more, crossline is more, earth's surface population is close on tunnel
Collection and heavy traffic.In order to reduce influence of the constructing tunnel to ground, ground settlement is controlled, shield construction is generallyd use
Subway tunnel, but when encountering some complicated geologicals, it needs using other construction method construction tunnels, in shield machine construction to
When tunnel through having excavated, need empty to push away shield machine after the tunnel construction sections excavated.
Chinese patent CN106150511B discloses a kind of shield driving formula sky and pushes through ground fissure bored tunnel construction method,
Comprising steps of one, ground fissure bored tunnel inner concrete guide table is constructed；Two, guide rail and reaction frame construction；Three, shield machine is whole
Pushing tow forward: shield machine is elapsed forward and is supported in shield host on twice guide rail, recycles the propelling cylinder of shield machine
