Cable anchorage system of cable-stayed anchorage type suspension tunnel extended by artificial island relay
The invention discloses a cable anchorage system of a cable-stayed anchorage type suspension tunnel extended by artificial island relay. The cable anchorage system comprises a plurality of pairs of cable anchorage artificial islands and a plurality of groups of cable-stayed cables; each pair of cable anchorage artificial islands are symmetrically arranged on the two sides of midspan of each span of the suspension tunnel; each group of cable-stayed cables are arranged between the each span of the suspension tunnel and each pair of cable anchorage artificial islands; a group of island wall staycable pipelines, a group of stay cable steering piers, a stay cable anchorage pier and a stay cable ramp are arranged on each cable anchorage artificial island; and one ends of the multiple cable-stayed cables are anchored to the outer surfaces of the two sides of each-span suspension tunnel at interval, the other ends of the multiple cable-stayed cables steer through a group of stay cable steering piers after penetrating through a group of island wall stay cable pipelines, then the other ends of the multiple cable-stayed cables are extended upwards along the stay cable ramps to the ground, and finally, the other ends of the multiple cable-stayed cables are anchored to the stay cable anchorage piers on the islands. According to the cable anchorage system, the length of the suspension tunnel can be increased, and the cable anchorage system can further be used for positioning the tunnel during tunnel pipe joint installation; and cable force monitoring and stay cable maintenance and replacement can further be carried out during tunnel operation.
本发明公开了一种人工岛接力延伸的斜拉锚碇式悬浮隧道的拉索锚碇系统，包括若干对拉索锚碇人工岛和若干组斜拉索；每对拉索锚碇人工岛对称地设在每跨悬浮隧道的跨中两侧；每组斜拉索设在每跨悬浮隧道与每对拉索锚碇人工岛之间；每座拉索锚碇人工岛上设置一组岛壁拉索管道、一组拉索转向墩、拉索锚碇墩和拉索坡道；多道斜拉索的一端间隔地锚固在每跨悬浮隧道的两侧外表面上，另一端穿过一组岛壁拉索管道后，再通过一组拉索转向墩进行转向，然后沿拉索坡道向上引伸至地面上，最后锚固于岛上的拉索锚碇墩上。本发明的拉索锚碇系统，不仅能加大悬浮隧道的长度，还能在隧道管节安装时用于隧道定位；在隧道营运期又能进行索力监测与拉索维护及更换。
