Side ditch cover plate for subsea tunnel and installation method
The invention relates to the field of subsea tunnel construction, in particular to a side ditch cover plate for a subsea tunnel and an installation method. The side ditches are synchronously formed in the one-time pouring forming process of the anti-collision curbstone and are of a U-shaped structure. The side ditch cover plate comprises a plurality of cover plate units arranged in the length direction of a side ditch, and the cover plate assembly is arranged at the opening position of the side ditch, is coplanar with an asphalt pavement of a subsea tunnel traffic lane and is used for covering the side ditch and widening the width of the traffic lane. The supporting piece is arranged below the cover plate assembly, used for supporting the cover plate assembly and comprises a fixing plate and a supporting plate, and the supporting plate comprises a side plate and an arc-shaped bottom support. When a vehicle rolls the cover plate assembly, the supporting plate moves downwards, the arc-shaped bottom support is pressed to deform, supporting force is generated, and the cover plate is prevented from falling off or turning on one side. And after rolling, the arc-shaped bottom support is reset, and the cover plate assembly is reset accordingly. The problems that an existing subsea tunnel is not provided with a side ditch cover plate, and a conventional cover plate is prone to falling or rollover under the rolling action of vehicles in the tunnel are solved.
本发明涉及海底隧道施工领域，尤其涉及一种用于海底隧道的边沟盖板及安装方法；所述边沟为防撞侧石在一次浇筑成型过程中同步形成的，边沟为U型结构；所述边沟盖板包括多组沿边沟长度方向设置的盖板单元，盖板组件设置于边沟开口位置，与海底隧道行车道的沥青路面共面，用于覆盖边沟并拓宽行车道宽度；支撑件设置于盖板组件下方，用于支撑盖板组件，包括固定板和支撑板，支撑板包括侧板和弧形底托。车辆碾压盖板组件时，支撑板向下运动，弧形底托受压形变，产生支撑力，避免盖板脱落或侧翻；碾压过后，弧形底托复位，盖板组件随之复位。本发明解决了现有的海底隧道没有边沟盖板以及常规盖板在隧道内车辆碾压作用下容易脱落或侧翻的问题。
