Lifting river-crossing bridge structure and using method thereof
The invention provides a lifting type river-crossing bridge structure and a using method thereof. The lifting type river-crossing bridge structure comprises a first connecting bridge body, a second connecting bridge body, a third connecting bridge body and bridge body lifting mechanisms arranged at the two ends of the second connecting bridge body in the length direction, wherein the first connecting bridge body, the second connecting bridge body, and the third connecting bridge body are successively arranged on a riverway. The outer ends of the first connecting bridge body and the third connecting bridge body are respectively connected with two banks of the riverway; the second connecting bridge body is arranged between the first connecting bridge body and the third connecting bridge body; auxiliary steel pipe piles of the bridge body lifting mechanisms are arranged on the two sides of the second connecting bridge body in the width direction. Lifting devices are arranged at the tops of the auxiliary steel pipe piles; traction ropes of the lifting devices are connected with lifting beams to move up and down; the second connecting bridge body is driven by the lifting beams on the two sides to move up and down. Because of the split type bridge body, up-down movement and positioning of the bridge body in the middle section are achieved through the bridge body lifting mechanisms; normal passing of the bridge body in the width direction of a river channel is achieved; meanwhile, passing of ships and the like in the length direction of the river channel can be achieved; and the structure is compact, use is flexible. The lifting type river-crossing bridge structure is suitable for wide popularization.
本发明提供了升降式跨河桥结构及其使用方法，通过在河道上的依序设置的第一联桥体、第二联桥体和第三联桥体，设在第二联桥体长度方向两端的桥体升降机构；第一联桥体和第三联桥体的外端分别与河道两岸连接；第二联桥体设在第一联桥体和第三联桥体之间；桥体升降机构的副钢管桩设在第二联桥体宽度方向的两侧；提升装置设在副钢管桩的顶部；提升装置的牵引绳与抬升梁连接来上下运动；第二联桥体通过两侧的抬升梁带动来上下运动。本发明通过设置分体式的桥体，并通过桥体升降机构来实现中间段的桥体的上下运动和定位，在实现河道宽度方向上桥体的正常通行的同时，还可以实现河道长度方向上的船只等通行，结构紧凑，使用灵活，适合广泛推广。
