Example Embodiment
[0034] The present invention will be further explained and illustrated below in conjunction with the drawings and specific embodiments of the specification.
[0035] The embodiment of the present invention provides a method for constructing a reinforced concrete lining composite lining structure of a shield tunnel, which includes the following steps:
[0036] Reinforcement treatment on the shield tunnel segments, or reserve connecting steel bars in the shield tunnel segments;
[0037] Bind or weld the connecting steel bar and the steel bar cage lined with reinforced concrete to form a shear key;
[0038] Support the steel cage and pour concrete to form a reinforced concrete lining;
[0039] The shield-concrete lining composite structure is constructed by shearing keys.
[0040] Further as a preferred embodiment, it also includes the following steps:
[0041] The shear key bears the internal water pressure and external water and soil pressure of the shield-concrete lining composite structu...
