Single-layer shield tunnel prefabricated local overlapping lane plate system and construction method thereof
The invention discloses a prefabricated local overlapping lane plate system of a single-layer shield tunnel and a construction method, the lane plate system comprises a shield segment, integral arc-shaped components are sequentially arranged in the shield segment along the length direction of the shield segment, and the plurality of integral arc-shaped components are connected into a whole through connecting pieces; the construction method comprises the steps that firstly, the multiple integrated arc-shaped components prefabricated in advance are installed in the inner space defined by the shield segments; then the multiple integral arc-shaped components are connected through connecting pieces to form a whole; after settlement of the tunnel is stable, an arc-shaped lining is cast in situ in the position, corresponding to the bottom of the integral arc-shaped component, of the shield segment, and it is guaranteed that the arc-shaped lining is tightly combined with the shield segment and the integral arc-shaped component; on the premise that the shield segment is not damaged and an arc-shaped lining formwork is omitted, it is guaranteed that the local strip-shaped arc-shaped lining and the shield segment are tightly combined, the prefabricated local overlapping integral type arc-shaped component is adopted, rapid construction is achieved, and the construction period is shortened.
本发明公开了单层盾构隧道预制局部叠合车道板体系及施工方法，车道板体系包括盾构管片，在所述盾构管片的内部并沿所述盾构管片的长度方向依次设置有整体式弧形构件，若干所述整体式弧形构件之间通过连接件连成整体；施工方法，包括首先在盾构管片围成的内部空间内安装提前预制的若干整体式弧形构件；随后将若干整体式弧形构件之间通过连接件相连形成整体；待隧道沉降稳定后，在盾构管片对应整体式弧形构件的底部位置现浇弧形内衬，并保证弧形内衬与盾构管片以及整体式弧形构件间结合紧密；本发明在不损伤盾构管片、取消弧形内衬模板前提下，保证局部条状弧形内衬与盾构管片间结合紧密，采用预制局部叠合整体式弧形构件，实现快速施工，缩短工期。
