Main-tower-free suspension bridge suitable for wide and deep canyons and construction scheme
The invention discloses a main-tower-free suspension bridge suitable for a wide and deep canyons and a construction scheme. The construction scheme comprises: performing inclined shaft construction; installing an anchoring body; installing a main cable saddle; installing a loose cable saddle; installing a cable fixing device; installing main cables; installing cables; and performing main beam and sling construction. The main-tower-free suspension bridge comprises an inclined shaft, an anchoring structure, a main cable, a main beam and slings, wherein the main beam is erected between canyons; the inclined shafts are arranged at two sides of the tunnel portal, and two inclined shafts are arranged at the tunnel portal at two ends; the anchoring device is combined with the inclined shaft and is fixed at the front end of the inclined shaft; the two main cables are connected with the corresponding anchoring structures at the two ends of the canyon correspondingly. One end of the sling is connected with the main cable and the other end is vertically connected with the girder. Mountains on the two banks of the canyon are fully utilized, anchoring structures are arranged in the mountains, the mountains are used for fixing main cables of the suspension bridge, so that arrangement of a main tower is avoided, the construction difficulty of the suspension bridge is further reduced, and meanwhile the construction cost of the suspension bridge is also reduced.
本发明公开了一种适用于宽深峡谷的无主塔吊索桥及施工方案。施工方案：斜井施工；安装锚固体；安装主缆鞍；安装散缆鞍；安装缆固装置；安装主缆；安装缆索；主梁和吊索施工。无主塔悬索桥包括斜井、锚固结构、主缆、主梁和吊索，主梁架设于峡谷间；斜井开设于隧道口的两侧，且两端隧道口均开设有两道斜井；锚固装置与斜井结合设置，锚固装置固定于斜井前端；主缆为两条且分别连接峡谷两端相对应的锚固结构；吊索一端连接主缆另一端垂直连接主梁用于悬固主梁。本发明充分利用峡谷两岸山体，在山体中设置锚固结构，利用山体来对悬索桥主缆进行固定从而避免设置主塔架设，进一步的降低了悬索桥的建造难度同时也降低了悬索桥的建造成本。
