Main-tower-free cable-stayed bridge suitable for wide and deep canyons and construction scheme
The invention discloses a main-tower-free cable-stayed bridge suitable for wide and deep canyons and a construction scheme. The construction scheme comprises the following construction steps that 1, inclined shaft construction is conducted; 2, anchoring body construction is carried out; 3, tunnel anchors are installed; and 4, the main beam and the stay cable are installed. The cable-stayed bridge comprises a main beam, stay cables, tunnel anchors, anchoring bodies and inclined shafts, the two inclined shafts are arranged on the two sides of a tunnel portal, and the tunnel portal at each end is provided with the two inclined shafts. The anchoring body is arranged at the front end, close to the tunnel portal, of the inclined shaft, and a groove matched with the tunnel anchor is formed in the anchoring body; the tunnel is anchored in the anchoring body; one end of the stay cable is fixedly connected to the main beam, and the other end of the stay cable is connected with the tunnel anchor; the main beam is erected between canyons. The stay cables are anchored into the upper body through the tunnel anchors to provide force needed by hanging and fixing of the main beam, it is avoided that a main tower is arranged in the wide and deep canyons, then the difficulty of bridge construction between the wide and deep canyons is lowered, and meanwhile the engineering cost of bridge construction between the wide and deep canyons is lowered.
本发明公开了一种适用于宽深峡谷的无主塔斜拉桥及施工方案，包括如下施工步骤：步骤一：斜井施工；步骤二：锚固体施工；步骤三：安装隧道锚；步骤四：安装主梁和斜拉索。斜拉桥包括主梁、斜拉索、隧道锚、锚固体和斜井，两道斜井开设于隧道口的两侧，且两端隧道口均开设有两道斜井；锚固体设置于斜井靠近隧道口的前端，且锚固体内设置有与隧道锚相适配的凹槽；隧道锚固定于锚固体内；斜拉索一端固定连接在主梁上，斜拉索另一端与隧道锚相连接；主梁架设于峡谷间。通过隧道锚将斜拉索锚入上体内提供主梁悬挂固定所需要的力，避免了在宽深峡谷中设置主塔，进而降低了宽深峡谷间桥梁施工的难度，同时降低了宽深峡谷间桥梁施工的工程造价。
