Subway shield tunnel enlarging station special area and station structure connecting method
InactiveCN101289938AEnsure safetyReduce distortionUnderground chambersTunnel liningSteel platesRebar
The invention provides a connecting method for connecting special duct pieces and a station structure in a subway shied tunnel extended station. The connecting method solves key problems that a station is built in subway regional shield extended construction process from aspects such as the constitution of the duct pieces, the assembly mode of the duct pieces, the connecting joint between the duct pieces and the station structure, etc. Through strengthening reinforcing bars, greater internal force born by the shield tunnel duct pieces in the process that the station is built by extension is satisfied, thereby guaranteeing the safety of the duct pieces; and after local duct pieces are removed, steel plates and steel reinforcement connectors are pre-embedded through straight-joint assembly and connected conveniently with the station structure, so that the connecting joint has enough rigidity to transfer axial force, bending moment and shearing force, the distortion of the joint is reduced, waterproofing processing to the joint can be effectively carried out, and the connection problem that the high-rigidity main structure of the station is connected with the high-flexibility structure of the duct pieces is solved. The shape of the special shield duct pieces are consistent with the shape of common subway regional tunnel shield duct pieces, so the same mould which is either applied to the special shield duct pieces or the common subway regional tunnel shield duct pieces can be used for production.
