Deepwater bare rock large-span steel trestle and platform combined system
The invention provides a deepwater bare rock large-span steel trestle and platform combined system which comprises a steel trestle, a construction platform, underwater brake piers and a specially-made Bailey truss, the construction platform is used for bridge construction operation, the steel trestle extends in parallel in the longitudinal direction of a construction design bridge to be connected to the construction platform, the steel trestle is of a large-span structure, the maximum clear span is 27 m, and the steel trestle is connected to the construction platform. The width of the bridge floor is 8 meters, thereby meeting two-way traffic of vehicles. The water flow impact resistance capacity is large, the net span is large, floating objects can flow through in the flood period, and the situation that accumulation is formed, so that the water blocking section is increased, and potential safety hazards are caused is avoided; according to the large-span steel trestle, the construction number of pile foundations in water can be reduced, the construction cost is reduced, the specially-made bailey truss is high in bearing capacity and can be repeatedly used for steel trestles of different forms, the use frequency of materials is increased, and the cost is indirectly saved.
本发明提供一种深水裸岩大跨度钢栈桥与平台组合体系，包括钢栈桥、施工平台、水中制动墩、特制贝雷桁架，施工平台用于桥梁施工作业，钢栈桥沿施工设计桥梁纵向平行延伸至连接施于工平台，钢栈桥为大跨度结构，最大净跨径27米，桥面宽度8米，满足车辆双向通行。本发明具有较大的抗水流冲击能力，净跨径大，能够在洪水期满足漂浮物流过，不至于形成堆积，以致增加阻水断面，造成安全隐患；大跨度钢栈桥能够减少水中桩基础施工数量，减少成本造价，特制贝雷桁架承载能力强，可重复多次利用于不同形式的钢栈桥，增加材料使用频次，间接节约成本。
