The invention relates to a self-floating type steel truss drilling platform structure and a construction method thereof.The self-floating type steel truss drilling platform structure comprises a steel truss system, a plurality of floating boxes are arranged at the bottom of the steel truss system, and the steel truss system is used for floating on the sea surface; the anchor piles are inserted into the steel truss system, the bottoms of the anchor piles extend out of the steel truss system, and the bottoms of the anchor piles are used for being inserted into a seabed rock stratum; the tops of the steel casing supporting piles are fixed to the steel truss system, the bottoms of the steel casing supporting piles are used for being inserted into a seabed rock stratum, the steel truss system can be machined in a factory, and then the steel truss system is conveyed in a floating mode in water by means of the buoyancy of the buoyancy box. The traditional mode that a barge is used for transporting the whole drilling platform to the pier position and then a large floating crane is used for hoisting is replaced, the construction risk is reduced, the construction speed is increased, meanwhile, the floating crane does not need to be used for hoisting the platform in blocks, and therefore the structure is high in construction speed, short in construction period, free of occupying floating crane resources for a long time, small in channel interference and low in construction cost.

    本发明涉及一种自浮式钢桁架钻孔平台结构及其施工方法,其包括:钢桁架系统,钢桁架系统的底部设有多个浮箱,钢桁架系统用于浮于海面;多个锚桩,锚桩插设于钢桁架系统,且锚桩的底部自钢桁架系统伸出,锚桩的底部用于插设于海床岩层;多个钢护筒支承桩,钢护筒支承桩的顶部与钢桁架系统固定,钢护筒支承桩的底部用于插设于海床岩层,钢桁架系统可以在工厂加工好,然后依托浮箱的浮力在水中浮运钢桁架系统,取代了传统的用驳船将钻孔平台整体运输至墩位再用大型浮吊吊装的方式,降低了施工风险,提高了施工速度,同时也无需使用浮吊分块吊装平台,因此,上述结构的施工速度快、施工周期短,无需长期占用浮吊资源,对航道干扰小,施工成本低。
