A drill head for a drilling device for making drill holes in insufficiently stable foundation by displacement of soil material has a base plate, with which the drill pipe end is detachably connected and is closable, on which base plate at least one drill head plate, oriented substantially perpendicular thereto, is placeable. Insertable in the lateral flanks is at least one curved plate, which is provided with first holding means, which are held in second holding means, which are attached on the lateral flanks of the drill head plate. The curved plate is designed in a way and is insertable in the flanks of the drill head plate such that its surfaces are effective as screw faces during the drilling process. The efficiency of the drilling can thereby be improved.

A tool for an offshore wind power foundation pile includes a steel pipe pile, a pile core, a pile cap, and a pile shoe. A cutting shoe portion is arranged at a bottom of the steel pipe pile, and an outer diameter of the pile shoe is larger than an outer diameter of the cutting shoe portion; the pile cap is detachably connected to the top of the steel pipe pile; the pile core is located in the steel pipe pile, the pile core is detachably connected to the pile shoe, and a length of the pile core is larger than or equal to a length of the steel pipe pile; the pile cap is further provided with a pile core accommodating groove and a pile core limiting portion; the pile core limiting portion includes a pile core limiting block and a limiting hole.

Foundation systems and methods using in-situ shaped pile-anchors that are particularly adapted for use in aquatic environments. The shaped pile-anchor of the invented foundation includes a concrete filled tubular metal casing, the bottom end of which is positioned at a predetermined depth in the ground (e.g., aquatic-floor soil) and the top end of which protrudes above the water or soil surface. Concrete fills the inside the metal casing, substantially all the way to the top end of the casing, forming an upper portion of a concrete column. The lower portion of the concrete column extends down below the bottom end of the metal casing and further into the ground. The lower portion is shaped to have a cross-section greater than the cross-section of the upper portion, which equals to the inner diameter of the tubular metal casing. A platform is coupled to one of more of the shaped pile-anchors to support a structure above.
