Anti-collision guardrail structure for existing masonry arch bridge and construction method
The invention discloses an anti-collision guardrail structure for an existing masonry arch bridge and a construction method. The anti-collision guardrail structure comprises a wall type anti-collision guardrail, an L-shaped guardrail base connected with the wall type anti-collision guardrail and an anchoring steel pipe arranged below the L-shaped guardrail base. The top of the L-shaped guardrail base is flush with the upper portion of the arch bridge, a glass fiber grating is arranged on the top of the L-shaped guardrail base, and a pavement is arranged on the top of the glass fiber grating. The anchoring steel pipe comprises a cylindrical pipe body, a perforated plate arranged on the periphery of the upper end of the pipe body, a round hole formed in the lower end of the pipe body and cement paste arranged in the pipe body, the anchoring steel pipe is perpendicular to a base plate of the L-shaped guardrail base, a drilled hole is formed in the existing arch bridge arch padding, and the bottom of the anchoring steel pipe is arranged in the drilled hole. The handrail and an original bridge form an integrated anti-collision structure, the overall stability is enhanced, under the action of automobile collision force, the structure deforms cooperatively, overall stress is achieved, and the action range of resistance is greatly expanded.
本发明公开了一种用于既有圬工拱桥的防撞护栏结构及施工方法，包括墙式防撞护栏、与墙式防撞护栏连接的L型护栏基座和设置在L型护栏基座下方的锚固钢管；L型护栏基座的顶部与拱桥上部齐平，L型护栏基座的顶部设置玻璃纤维格栅，玻璃纤维格栅的顶部设置铺装；锚固钢管包括圆柱形管体、设置在管体上端外周的开孔板、设置在管体下端的圆孔和设置在管体内部的水泥浆，锚固钢管与L型护栏基座底板垂直，既有拱桥拱上填料设置钻孔，所述锚固钢管的底部设置在钻孔里。本发明将栏杆与原桥梁形成整体式防撞结构，增强了整体的稳定性，在汽车撞击力的作用下，结构协同变形，整体受力，将抵抗力的作用范围大大拓展。
