Suspension bridge anchoring system adopting parallel prestressing tendons and construction method of suspension bridge anchoring system
The invention discloses a suspension bridge anchoring system adopting parallel prestressing tendons and a construction method thereof, the suspension bridge anchoring system comprises an anchorage part, a main cable anchor head part and a connecting part, the anchorage part comprises an anchor body, a front anchor backing plate, a rear anchor backing plate, the prestressing tendons, a front anchor assembly, a rear anchor assembly and prestressing tendon pipelines arranged in parallel; the main cable anchor head part comprises a main cable strand, a cable strand anchor head and a cable strand connecting plate; the connecting part comprises a connector, a first pull rod and a second pull rod; the connector comprises a bottom plate, and a first side plate and a second side plate which are vertically and fixedly connected with two sides of the bottom plate; the first side plate and the second side plate are respectively hinged with one ends of the first pull rod and the second pull rod along the same rotating axis; the other ends of the first pull rod and the second pull rod are clamped to the upper end face of the cable strand connecting plate. And the first pull rod and the second pull rod are parallel to the main cable strand. According to the suspension bridge anchoring system adopting the parallel prestressing tendons and the construction method of the suspension bridge anchoring system, it can be ensured that the stress directions of the pull rods and the main cable strands are consistent, and the construction difficulty is greatly reduced.
本发明公开了一种采用平行预应力束的悬索桥锚固体系及其施工方法，包括锚碇部、主缆锚头部和连接部，锚碇部包括锚体、前锚垫板、后锚垫板、预应力束、前锚组件、后锚组件和平行布设的预应力束管道；主缆锚头部包括主缆索股、索股锚头、索股连接板；连接部包括连接器、第一拉杆和第二拉杆；连接器包括底板、底板两侧垂直固定连接的第一侧板和第二侧板；第一侧板和第二侧板沿同一转轴线分别与第一拉杆和第二拉杆的一端铰接；第一拉杆和第二拉杆的另一端卡接于索股连接板的上端面；第一拉杆和第二拉杆与主缆索股平行布设。本发明公开的一种采用平行预应力束的悬索桥锚固体系及其施工方法，能够确保拉杆与主缆索股的受力方向一致，大幅降低施工难度。
