Definitions

  • the invention relates to a foundation according to the preamble of claim 1.
  • Such a foundation is known from CH-A-333106. It is proposed there to drive piles into the soil in the form of hollow profiles with an internal soil stabilization element while compressing the soil enclosed in the hollow profile, at least in the final phase of driving in.
  • the earth stabilization element is a plate-like closure, which is either arranged firmly in the interior of the hollow profile or bears against a stop during the final phase of driving in and thus becomes earth stabilizing.
  • the upper part of the known anchoring section protrudes from the ground and is suitable for connecting a mast or the like.
  • the known pile can be driven into the soil relatively easily, the soil enclosed in the inside of the pile and compressed by the above-mentioned soil stabilization element ensuring a considerably better hold in the ground than conventional piles or other hollow profile-like foundations.
  • the soil enclosed inside the pile and compressed in the final phase of driving in gives the pile approximately the characteristics of a full-body pile in this area.
  • the present invention has for its object to improve a foundation of the known type so that an even higher degree of anchoring is achieved.
  • the inner earth stabilization element provided according to the invention has, in addition to the earth stabilization function, also a stability-increasing function.
  • the section of the hollow profile which serves as an anchoring section and protrudes from the floor is extremely sensitive to bending and vibration stresses due to its thin wall thickness.
  • the inner ground stabilization element stiffens this sensitive section so that high bending and vibration loads can be absorbed.
  • it is not the wall thickness of the hollow profile used as the anchoring section that is decisive in the foundation according to the invention, but rather the mass formed by the hollow profile, the earth enclosed inside the same and the ground stabilization element (concrete insert or the like).
  • the mast or support pillar or the like is attached to the foundation according to the invention, such that the mast, support pillar or the like. is located completely above the surface of the earth, it is possible to use different materials for the anchoring section (earth part) and the part arranged above the earth, i.e. mast, pillar or the like.
  • a material can be used for the mast or the like which is resistant to air corrosion but does not have to be resistant to «earth corrosion».
  • a steel mast or pillar or the like is preferably made of carbon steel known under the trademark "Corten", which is very cheap and very resistant to air corrosion, but not to earth corrosion (earth acids).
  • the materials and sheet thicknesses for the anchoring section are of course chosen.
  • an outer ground stabilization element can additionally be provided in the upper part of the anchoring section, preferably at a distance from its upper end, this being designed in the manner of a collar (flange) projecting outwards.
  • This outer earth stabilization element can also be arranged to be longitudinally displaceable at the anchoring section in order to achieve an even higher earth stabilization and weighed down with a heavy weight, so that the soil immediately surrounding the anchoring section is solidified during the entire duration of the driving in or vibrating of the anchoring section.
  • the ratio of (length of the anchoring section) to (outer diameter of a tubular anchoring section or the greatest width of an anchoring section with an angular, preferably square cross section) to (wall thickness of the anchoring section) is approximately (1000-5000 mm): (200-1 500 mm ): (2.0-10.0 mm, especially 2.0-6.0 mm).
  • This ratio shows the small wall thickness of the anchoring section of the foundation according to the invention with extremely high stability in the ground. The use of materials is extremely low and the introduction into the soil is unproblematic.
  • the foundations designed according to the invention are u. a. also as a temporary support for heavy construction equipment, cranes, excavators, etc., in rough terrain.
  • the foundations can be set or built very quickly (approx. 50-90 seconds per foundation) with relatively light construction equipment or even from the air. This eliminates the need to erect concrete stands for heavy cranes or the like.
  • the removal of the foundations according to the invention is also very simple and in particular environmentally friendly.
  • the concrete or asphalt block cut out of the concrete or asphalt surface can be additionally weighted to increase the soil stabilizing effect while the anchoring section is vibrating in by means of a further concrete block or the like.
  • Also advantageous in the method according to claim 8 is the guiding function of the separating cut in the concrete or asphalt surface for the anchoring section and the stabilizing effect of the concrete or asphalt surface around the anchoring part.
  • the foundation for a mast or the like consists of an anchoring section 2 in the form of a square hollow profile each having the same edge length.
  • the anchoring section 2 is vibrated approximately vertically into the ground.
  • an outer ground stabilization element in the form of a collar 4 is provided at the upper end of the square hollow profile.
  • the collar 4 is a sheet metal construction with a peripheral flange 6 and on the underside of which welded angle plates 7, a total of four angle plates being provided, which are arranged in the region of the center lines of the four sides of the hollow profile, in such a way that they are distributed uniformly over the circumference of the hollow profile are.
  • the respective upper, horizontally extending legs of the angle plates 7 are welded to the underside of the Umfarig flange 6, while the other, approximately vertically extending legs of the angle plates 7 on the outer lateral surface of the hollow Profiles or anchoring section 2 attached, preferably also welded.
  • an earth stabilization element in the form of a concrete insert 3 is arranged to be longitudinally displaceable, so that it acts on the soil penetrating from below into the interior of the anchoring section 2, which is open and toothed and is open at the bottom, throughout the vibration.
  • a ventilation opening 11 is provided, through which the air present above the inner concrete insert 3 can escape during the vibrating in, possibly with concrete dust arising during the vibrating in.
  • the lower end of the anchoring section 2 is toothed or serrated (four serrations at the four corners of the anchoring section) in order to obtain a minimal earth resistance cone and thus additionally reduce the earth resistance when vibrating.
  • the weight of the concrete insert 3 is between about 100 kg to about 300 kg. This is u. a. depending on the nature of the soil.
  • the anchoring section 2, driven or vibrated into the earth consists of highly corrosion-resistant steel, e.g. B. chrome steel, which is also resistant to earth acids, etc.
  • the mast or the like arranged above the surface of the earth preferably consists of an air corrosion-resistant material, and the like. a. also wood.
  • the inner and outer ground stabilization elements 3 and 4 have, in addition to their ground stabilizing effect, the additional advantage that an increased kink resistance of the foundation in the upper connection area for the mast, support pillar or the like is achieved. Overall, the foundation described is extremely stable against vibrations, bending stresses, and tensile and compressive loads.
  • the anchoring section 2 is preferably made of ferritic chromium steel with a low carbon content and with or without the addition of molybdenum.
  • the ratio "outer diameter of the collar 4 to" edge length of the anchoring section 2 is between approximately 2: 1 and 4: 1.
  • the outer casing of the same can be provided with helically extending grooves or ribs which, when the anchoring section vibrates into the ground, cause the latter to rotate about the longitudinal axis. Through this rotary movement, the toothed lower edge of the anchoring section 2 shown in FIG. 1 becomes effective in the manner of a saw.
  • the edge length is approximately 200-1,500 mm and the wall thickness is approximately 2-10 mm, preferably 3-6 mm.
  • the total weight of the foundation according to FIGS. 1 and 2 ranges between approximately 100 to 2000 kg, depending on the length, cross section and sheet thickness of the anchoring section.
