Pedestrian suspension bridge with cylindrical net-shaped space cable dispersedly anchored on canyon hillside and construction method thereof
The invention provides a pedestrian suspension bridge with cylindrical net-shaped space cable dispersedly anchored on canyon hillside. A traditional pedestrian suspension bridge with a parallel cable system is reformed, concentrated heavy cables are changed into dispersed uniparted hyperboloid space cable nets, the uniparted hyperboloid space cable nets are anchored on hillsides on two sides of a canyon scenic area, a plurality of internal oval ring beams are arranged in the uniparted hyperboloid space cable net, double-helix external spiral stirrups in the forward direction and the reverse direction are wound on the outer portion of the uniparted hyperboloid space cable net, the uniparted hyperboloid space cable net droops to form a cylindrical net-shaped space cable system, and the whole bridge is not provided with a bridge tower. The bridge deck system stiffening beams and the central annular beam are suspended by the sling system, the bridge deck system stiffening beams are placed on the hillside bodies on the two sides, and the lower wind-resistant cable system is connected with the bridge deck system stiffening beams. The suspension bridge has the advantages of being beautiful in shape, convenient to construct, good in wind resistance stability and low in economy, and the super-large span canyon scenic area pedestrian suspension bridge with the span of 600-800 meters can be built.
本发明提供一种筒网状空间缆索分散锚固峡谷山坡的人行悬索桥，改革传统的平行缆索体系人行悬索桥，将集中的粗重缆索改为分散的单叶双曲面空间缆索网，单叶双曲面空间缆索网锚固于峡谷景区两侧山坡体之上，多道内部椭圆形环梁设置在单叶双曲面空间缆索网的内部，正反两个方向的双螺旋形式的外部螺旋箍筋缠绕于单叶双曲面空间缆索网的外部，单叶双曲面空间缆索网下垂后形成筒网状空间缆索体系，全桥没有一个桥塔。吊索体系悬吊桥面系加劲梁和中央环形梁，桥面系加劲梁搁置在两侧山坡体之上，下部抗风缆索体系与桥面系加劲梁相连接。具有造型漂亮、施工方便、抗风稳定性好和经济低的优点，可建造600～800米跨径的超大跨径的峡谷景区人行悬索桥。
