The invention relates to the technical field of ship equipment, and discloses a workboat and a construction method for pile sinking of a single pile foundation, the workboat comprises a pile sinking boat body, a pile sinking mechanism is installed in the pile sinking boat body, a lifting mechanism is installed outside the pile sinking boat body, and a driving mechanism is installed outside the pile sinking boat body. In the drilling construction process, the pile sinking rotary disc is arranged to drive the construction pile body and the drilling sleeve to rotate, and when rotating forwards in the drilling sleeve, the construction drill bit can gradually move downwards from the initial position to conduct drilling operation through threaded connection with the drill rod separation disc; when the construction drill bit reversely rotates in the drilling sleeve, the construction drill bit can move upwards to the initial position through threaded connection with the drill rod separation disc, after drilling is completed, a construction pile body can be driven by the pile sinking rotary disc to immediately move to the position above a drilled hole, and therefore secondary searching and positioning of the drilled hole are avoided, and the drilling and pile sinking construction time is greatly shortened.
本发明涉及船舶设备技术领域,公开了一种施工船及用于单桩基础沉桩的施工方法,包括沉桩船体,所述沉桩船体的内部安装有沉桩机构,所述沉桩船体的外部安装有升降机构,所述沉桩船体的外部安装有驱动机构。本发明在进行钻孔施工过程中通过设置有沉桩转盘带动施工桩体和钻孔套筒转动,施工钻头在钻孔套筒内部正向转动时会通过与钻杆分隔盘的螺纹连接从初始位置逐渐向下移动进行钻孔作业,施工钻头在钻孔套筒的内部反向转动时会通过与钻杆分隔盘的螺纹连接向上移动到初始位置,在钻孔完成后能够通过沉桩转盘带动施工桩体立刻移动到钻孔的上方,从而避免了二次对钻孔进行寻找定位,大大减少的钻孔沉桩施工时间。
