Large-curvature ramp bridge anti-overturning structure crossing existing road and construction method of large-curvature ramp bridge anti-overturning structure
The invention relates to an anti-overturning structure of a large-curvature ramp bridge crossing an existing road, which is characterized in that a ramp bridge steel box girder is divided into a ramp bridge curved arc inner side bridge section and a ramp bridge curved arc outer side bridge section which are positioned on bridge piers which are arranged on two sides and are provided with temporary supporting jig frames, and the existing road is arranged below the ramp bridge steel box girder; cable supporting vertical rods are arranged on the constructed ramp bridge steel box girders on the two sides, and the tops of the vertical rods are stably connected through connecting rods; a cable rope fixing lug plate is arranged on a constructed ramp bridge steel box girder top plate, a cable rope fixing lug plate is arranged on a cross-road ramp bridge steel box girder top plate, and a cable rope ground anchor is arranged on the ground on the inner side of a bent arc of the constructed ramp bridge; a stable system of the steel box girder bridge section is formed through the cable ropes and the vertical rods; a stable system of the steel box girder bridge section is formed through the cable ropes and the vertical rods. It is ensured that the steel box girder does not overturn, and meanwhile the whole construction process does not affect vehicle passing of an existing road below.
本发明涉及一种跨既有道路大曲率匝道桥防倾覆结构，匝道桥钢箱梁，分为匝道桥弯弧内侧桥段和匝道桥弯弧外侧桥段，落位于两侧的安装临时支撑胎架的桥墩上,其下方为既有道路；在两侧已施工的匝道桥钢箱梁上设置缆风支撑立杆，立杆顶部采用联系杆相连稳定；在已施工的匝道桥钢箱梁顶板上设置缆风绳固定耳板，在跨路匝道桥钢箱梁顶板上设置缆风绳固定耳板，在已施工的匝道桥弯弧内侧地面设置缆风绳地锚；通过缆风绳与立杆形成钢箱梁桥段的稳定体系；通过缆风绳与立杆形成钢箱梁桥段的稳定体系。本发明确保钢箱梁不会发生倾覆，同时施工全过程不影响下方既有道路的车辆通行。
