Double-layer lane structure in shield tunnel
The invention discloses a double-layer lane structure in a shield tunnel. The double-layer lane structure comprises a tunnel body. An upper-layer lane plate is arranged in the tunnel main body; a left elastic support and a right elastic support are arranged on the two sides of the bottom end of the upper-layer lane plate correspondingly. A left side connecting plate is arranged at the bottom end of the left side elastic support; the left side of the left side connecting plate is connected with the tunnel main body; the bottom end of the left side connecting plate is connected with the tunnel body through a left side stand column. The bottom end of the right elastic support is connected with the tunnel body through a right stand column. A right side connecting plate is arranged on the right side of the upper-layer lane plate; and the right side of the right side connecting plate is connected with the tunnel main body. The elastic supports are arranged on the bases on the two sides of the upper-layer lane plate, the deformability between the upper-layer lane plate and the stand columns and the bottom plate on the two sides is improved, and the problems that due to deformation of tunnel segments, local stress concentration and cracking of an internal structure are caused are solved.
本发明公开了一种盾构隧道内部双层车道结构，包括：隧道主体；所述隧道主体内部设置有上层车道板；所述上层车道板底端两侧分别设置有左侧弹性支座和右侧弹性支座；所述左侧弹性支座底端设置有左侧连接板；所述左侧连接板左侧与所述隧道主体相连接；所述左侧连接板底端通过左侧立柱与所述隧道主体相连接；所述右侧弹性支座底端通过右侧立柱与所述隧道主体相连接；所述上层车道板右侧设置有右侧连接板；所述右侧连接板右侧与所述隧道主体相连接。本发明通过在上层车道板两侧底座布置弹性支座，增大了上层车道板与两侧立柱及底板之间的变形能力，解决了因隧道管片变形而引起内部结构局部应力集中及开裂的问题。
