The invention discloses a complex sea area floating type steel truss construction platform, and relates to the technical field of bridge construction, the complex sea area floating type steel truss construction platform comprises a steel truss system, a plurality of floating boxes, a positioning system and a plurality of damping devices, the plurality of floating boxes are arranged at the bottom of the steel truss system, and the positioning system comprises a plurality of cable collecting devices, a plurality of positioning steel cables and a plurality of concrete gravity anchors; the plurality of cable collecting devices are mounted on the steel truss system, one end of each positioning steel cable is connected with one cable collecting device, and the plurality of concrete gravity anchors are arranged around the steel truss drilling platform and are connected with one cable collecting device through the plurality of positioning steel cables; the multiple vibration reduction devices are annularly arranged on the side of the steel truss system at intervals, and one vibration reduction device is movably connected with one positioning steel cable and applies acting force to the positioning steel cable. A jacket structure with a large steel amount is not needed, the material cost is reduced, the construction speed is increased, acting force is applied to the multiple positioning steel cables through the multiple damping devices, fatigue damage to the positioning steel cables is avoided, and the safety risk is reduced.

    本发明公开了一种复杂海域浮式钢桁架施工平台,涉及桥梁施工技术领域,包括:钢桁架系统、多个浮箱、定位系统和多个减振装置,多个浮箱设于钢桁架系统的底部,定位系统包括多个收缆装置、多根定位钢缆和多个混凝土重力锚,多个收缆装置安装于钢桁架系统上,每根定位钢缆一端与一个收缆装置连接,多个混凝土重力锚抛设在钢桁架钻孔平台周围,且通过多根定位钢缆与一个收缆装置连接;多个减振装置环向间隔设在钢桁架系统的侧方,一个减振装置与一根定位钢缆活动连接并对其施加作用力。本发明无需用钢量较大的导管架结构,降低材料成本,提高施工速度,且通过多个减振装置对多根定位钢缆施加作用力,避免定位钢缆发生疲劳损伤,降低安全风险。
