Underwater tunnel, underwater tunnel construction method and water shield tunneling machine for underwater tunnel construction
The invention discloses an underwater tunnel, an underwater tunnel construction method and a water shield tunneling machine for underwater tunnel construction. The underwater tunnel comprises a tunnelbody and a tunnel entrance and exit pipeline which are arranged underwater, wherein the tunnel body comprises a main pressure-bearing pipeline, a waterproof constraint pilot pipeline arranged outsidethe main pressure-bearing pipeline in a sleeving manner, a filling pressurization layer filling the space between the waterproof constraint pilot pipeline and the main pressure-bearing pipeline, anda position locking structure used for fixedly mounting the waterproof constraint pilot pipeline on an underwater foundation; a port of the waterproof constraint pilot pipeline is connected and communicates with the tunnel entrance and exit pipeline; the main pressure-bearing pipeline comprises tunnel segments which are spliced to form the main pressure-bearing pipeline; and the tunnel segments inthe waterproof constraint pilot pipeline are lined on the inner wall of the waterproof constraint pilot pipeline. The construction process can be simplified, the requirement on construction environment conditions is reduced, the construction risk is reduced, the construction cost is effectively reduced, the construction period is effectively shortened, and the waterproofness of the tunnel is improved.
本发明公开了水下隧道、水下隧道施工方法及水下隧道施工用水盾构机，该水下隧道包括设于水下的隧道本体和隧道出入口管道，所述隧道本体包括主承压管道，套设于所述主承压管道外的防水约束先导管道，填充于所述防水约束先导管道与所述主承压管道之间的充填加压层，以及用于将所述防水约束先导管道固定安装于水下地基上的位置锁定结构；所述防水约束先导管道的端口与所述隧道出入口管道衔接且相互贯通，所述主承压管道包括拼装构成所述主承压管道的隧道管片，所述防水约束先导管道内的所述隧道管片衬砌于所述防水约束先导管道内壁。可简化施工过程，降低施工环境条件要求，降低施工风险，有效降低施工成本和施工周期，提高隧道的防水性。
