Large-span horizontal pulling type cylindrical net-shaped pedestrian landscape suspension bridge and construction method thereof
The invention relates to a large-span horizontal pulling type cylindrical net-shaped pedestrian landscape suspension bridge and a construction method thereof. A horizontal pulling type pedestrian suspension bridge in a canyon scenic area is reformed by referring to a Tibet rattan net bridge, heavy concentrated cables are changed into dispersed single-blade double-curved-surface barrel net-shaped space cables, a small number of oval rigid stiffening rings are arranged in a barrel net, double-spiral steel wire stirrups in the positive direction and the negative direction are wound around the outer portion of the barrel net, and therefore, the large-span horizontal pulling type cylindrical net-shaped pedestrian landscape suspension bridge is formed. The single-blade double-curved-surface cylinder net-shaped space cables, the oval rigid stiffening rings and the double-helix steel wire stirrups work cooperatively, the torsional rigidity and lateral rigidity of the pedestrian suspension bridge are improved, and the pedestrian suspension bridge has good wind-resistant stability. According to the bridge tower anchoring barrel net-shaped space cable with the curved double-limb pier column and the huge oval steel ring tower cap, the weight of a single-strand cable is reduced through the scattered barrel net-shaped space steel wire cable, and construction is convenient. A transparent glass bridge deck is embedded in a bridge deck truss, cirrus grass is wound on the cylinder net-shaped space cable in a double-spiral mode, sunlight is shielded, ecological and environment-friendly effects are achieved, the appearance is attractive, tourists walk in the cylinder net-shaped suspension bridge, and personal safety can be guaranteed.
本发明涉及一种大跨径平拉式筒网状人行景观悬索桥及其施工方法。借鉴西藏藤网桥,改革峡谷景区平拉式人行悬索桥,将粗重的集中缆索改为分散的单叶双曲面筒网状空间缆索,在筒网内部设置少量的椭圆形刚性加劲环,在筒网外部缠绕正反方向的双螺旋钢丝箍筋,形成一种大跨径平拉式筒网状人行景观悬索桥。单叶双曲面筒网状空间缆索、椭圆形刚性加劲环和双螺旋钢丝箍筋三者协同工作,提高人行悬索桥的抗扭刚度和抗侧刚度,具有良好的抗风稳定性。曲线形双肢桥墩柱和巨型椭圆钢环塔帽的桥塔锚固筒网状空间缆索,分散的筒网状空间钢丝缆索减轻了单股缆索重量,方便施工。桥面桁架上内嵌透明玻璃桥面板,藤蔓草双螺旋状缠绕筒网状空间缆索,遮蔽阳光,生态环保,造型漂亮,游客行走在筒网状悬索桥之中,可确保人身安全。
