摘要： The invention concerns a device designed to be anchored in the ground of granular composition, comprising a rod with hollow tubular section, the latter having an open upper end wherein can be fixed an object and an intermediate orifice on its flank. The orifice enables evacuation of the granular matter constituting the ground and penetrating into the rod through its open lower end when the device is being anchored to the ground.

摘要： The periphery of a downwardly tapering bearing foundation member (1), e.g. made of reinforced concrete, has a spirally extending ridge (7) which projects from the tapering peripheral surface (4) and which is small in radial and axial extent compared with the axial spacing (P) of the turns of the spirally extending ridge. The lower end of the foundation member (1) is placed in the ground and it is rotated while subjected to a downward force, preferably greater than the force of gravity. The spirally extending ridge (7) bites into the subsoil and urges the foundation member (1) downwards while the tapering periphery (4) displaces and compacts the subsoil.

摘要： A pile (1) has a plurality of external parallel helical fins (30, 31, 32) along substantially the whole length of the pile (1). At least one of the fins (30, 31, 32) has a wedge-shape cross section. The pile (1) can be driven into a substrate by applying a force to the pile (1) substantially parallel to the longitudinal axis (2) of the pile (1), the force having substantially no rotational component about the longitudinal axis (2). The helical fins (30, 31, 32) on the pile (1) cause the pile (1) to rotate in the substrate and thereby penetrate the substrate as the force is applied.

摘要： Concrete pile (1) for supporting structures a certain distance above ground level (M), such as viaducts and the like. The pile is characterized in that it is entirely prefabricated and comprises a hollow cylindrical shaft (2), which contains an upper pier section (2a) and a foundation section (2b). The foundation section has an oppen bottom end (3) and is in its area which adjoins the said open end provided with an external screw thread (4, 5), for screwing said pile in the ground. The shaft of said pile containing a number of ducts (20), which are distributed over the circumference, which ducts open out on the outside of the shaft in the area of the external screw thread. The invention also relates to a method for positioning said pile in the ground, said method being characterized in that while the pile is being screwed in, a liquid medium is injected on its outside via the ducts (20) and the position of the pile while it is being screwed in is controlled by varying locally along the external circumference of the pile, the volume and/or pressure of the supplied liquid medium.

摘要： The invention relates to a method and apparatus for providing in the ground, free from vibration, a foundation pile having a slender section and an enlarged pile base (2). The method comprises the steps of
driving a drill tube (17) into the ground with rotation under axial pressure, which is closed at the lower end by means of a preformed hollow displacement tip (3) and is provided on the outer surface thereof with helical coils (13), until the displacement element has penetrated into a bearing ground layer (P) for a certain distance;
subsequently increasing the distance between the lower edge of the drill tube (1) and the displacement tip (3) forming an enlarged pile base (2) after penetration into a bearing ground layer (P) due to the pile base (2) being forced with rotation into the bearing ground layer (P) for a distance of at least twice the outer diameter of the pile base (2); and
providing in the thus formed borehole a prefabricated slender foundation pile (11) whose section is considerably smaller than that of the drill tube (11), while the lower end of the foundation pile (11) comes to rest on the pile base (2).摘要翻译： 本发明涉及一种用于在地面提供一种方法和装置，无振动，具有一个细长的截面的地基桩和放大桩基座（2）。 该方法包括一个在其下端由一个预先形成的中空位移尖端（3）的封闭，并与螺旋设置在其外表面上的驱动钻管（17）到地面与下轴向压力旋转的步骤，所有 线圈（13），直到位移元件已经渗透到对某些距离的轴承接地层（P）; 随后增加钻管的下边缘之间的距离（1）和所述位移尖端（3）上形成渗入轴承接地层（P）后放大桩基座（2）由于桩基座（2）被强制 与旋转成的距离的轴承接地层（P）的至少两倍的桩基础的外径（2）; 并在这样形成的钻孔的预制细长地基桩提供（11），其截面比钻管（11）的相当小的，而地基桩（11）的下端部贴靠在该桩基础（2 ）。
