The invention relates to a foundation pile for producing a foundation for a structure in water, in particular an offshore structure, having a portion (12) situated in the ground (4) and in which the outer diameter (19) increases towards the water bed (26), and the outer diameter (19) is designed as a function of the distribution of bending moment (16) acting on the pile (10), and to a method for producing a foundation for a structure in water, preferably an offshore structure, in which a pile (10) is lowered in the ground (11) into an opening (21), wherein the opening (21) in the ground (11) is produced using boring technology, an overcut (22) is generated during boring such that the opening (21) is larger than the pile (10), and the overcut (22) is filled with a suspension, wherein the pile (10) is introduced with an increasing outer diameter (19) into the opening (21), and wherein the outer diameter (19) increases towards the water bed (26).
摘要:
The invention relates to a method and a device for creating an underwater foundation of a building, wherein a base element is provided as a module carrier (11) at the erection site and a pile (6) forms the foundation to be created or is a component of the foundation, wherein the pile (6) is implemented as a hollow body. The aim of the invention is to allow the creation of a foundation in geologically difficult conditions, while simultaneously reducing noise emissions in sensitive areas. The aim is achieved by clamping the pile (6) in a pivot module (13), by erecting the pile (6) by way of pivoting the pivot module (13), until the desired driving direction into the ground (9) relative to the horizontal is achieved, by locking the pivot module after erecting the desired slope, by sinking the pile (6) to the floor (8) of the water system (7) and pressing it into the floor (8) until a limit value of a driving force is reached, by installing a sinking device (24) in the pile (6) and sinking it to the floor (8), by loosening the rock (9) below the pile (6) and sinking the pile (6) until the final depth is reached.

The invention relates to a method for erecting a underground construction, in which a shaft (30) is sunk at the erection site, and the shaft is closed off by a cover (32) in which an opening is provided. Furthermore, a lifting/lowering device (37, 38) is provided in the area of the opening, a locking mechanism (57) is provided in the shaft (30) below the opening, a segment of the construction (46) is provided in the area of the opening and is connected to the lifting/lowering device (37, 38) and is lowered through the opening, down to the locking mechanism (57), and is locked, and is then released from the lifting/lowering device (37, 38) after being locked, a process cycle is performed in which a further segment of the construction (40) is connected to the locked segment of the construction (46), the construction segments located in the shaft are lowered, and said process cycle is repeated until the segments required for erecting the underground construction have been inserted into the shaft.
摘要:
In a method and associated devices for testing the coating of a pipeline while the pipeline is laid in a liquid-filled borehole, the pressure of an advancing device (1) is transmitted to a drill head (4) via a pipeline (2) and an electrically non-conductive insulating coupling (3), and the control and supply wires (9) for the drill head (3) are guided and/or designed within the pipeline (2) in such a way that the control and supply wires (9) allow no electrical contact between the drill head (3) and the ground (12) with the pipeline (2), and the integrity of the coating (7) of the pipeline (2) that is surrounded by a liquid (6) in the borehole (5) is verified during the laying process of the pipeline (2) by means of a measuring apparatus (8).
摘要:
Eine Bohrvorrichtung zum Verlegen von Rohrleitungen (1) im Boden (2) wird mit einem Bohrkopf (3) am Anfang einer Rohrleitung (1) ein Bohrloch (4) von einer Startgrube (5) entlang einer Verlegelinie (6) zu einer Zielgrube (7) erstellt, wobei der Bohrkopf (3) über eine schmale vertikale Verbindungsvorrichtung (8) mit einem Verlegefahrzeug (9) an der Geländeoberfläche (10) verbunden ist. Der vom Bohrkopf (3) gelöste Boden wird aus dem Bohrloch (4) entnommen und nach über Tage gefördert. Die erforderliche Kraft für den Bohr- und Verlegevorgang wird vom Verlegefahrzeug (9) und/oder einer Vorschubeinrichtung (12) in der Startgrube (5) aufgebracht.
