    摘要： Provided is a method of installing a Gravity Based Structure ("GBS", 7). The method involves installing a substructure (10) at a position to be below the GBS (7), the substructure (10) providing a foundation upon which to support the GBS (7) when installed, and installing the substructure (10) to define at least an annular support region (14) for the GBS (7). The method further involves installing the GBS (7) above the substructure (10) with the annular support region (14) therebelow, and pre-installing the substructure (10) in advance of the GBS (7), with the GBS (7) being installed above the substructure (10) subsequent to the substructure's installation.

    摘要： A gripping assembly (1) for a pile (CP) provided with a longitudinal axis (AL) and axially delimited by a longitudinal end (LE) having a given shape, by a first shell (IM) and by a second shell (EM) which delimit the longitudinal end (LE) from the inside and from the outside, respectively; the assembly (1) comprising a frame (10) provided with a central portion (12) shaped to support a plurality of linear actuators (20) about a central axis (120), where each linear actuator (20) is provided with a stem (24) carried by the central portion (12) having a radial orientation, and with an armature (22) that terminates with a free end (220) which carries the grasping means (30) designed to radially couple with at least one of the first shell (IM) and second shell (EM) of the end (LE) of the pile (CP); the central portion (12) carrying a plurality of arms (14) which extend radially around the central axis (12); each arm (14) being provided with a radial guide (140) to which the grasping means (30) are coupled in a freely slidable manner.

    摘要： The disclosure relates a construction method for an underwater pipe pile foundation and the underwater pipe pile foundation, wherein the method comprises the following steps: disposing construction interlayers (20) on a side wall of a hollow steel pipe pile body (3) in an axial direction, disposing a plurality of construction holes (17) in the sides, away from an inner cavity of the pipe pile body (3), of the construction interlayers (20) in the axial direction, the plurality of construction interlayers (20) being disposed at intervals in the circumferential direction of the pipe pile body (3), and covering the construction holes (17) with plugging plates (2), hoisting and sinking the pipe pile body (3) on a position to be constructed, and sinking the pipe pile body (3) to a predetermined elevation; respectively disposing explosive impact apparatuses (5) at the plurality of construction holes (17), detonating the explosive impact apparatuses (5) to bomb out the plugging plates and form soil body cavities (7) in soil bodies on positions corresponding to the construction holes (17); laying down a grouting pipe (15) to the bottom of the pipe pile body (3) along the construction interlayers (20) and grouting the pile tip and the soil body cavities (7).
