Definitions

  • the invention relates to a foundation according to the preamble of claim 1.
  • Such a foundation is e.g. known from US-PS 1 784 568. It is proposed there to place telegraph poles or the like at the end of an anchoring section, e.g. in the form of an H or tubular profile, releasably flanged. For the purpose of anchoring the H or tubular profile in the ground, this is first excavated at the point where the telegraph poles were erected, then the anchoring section is fixed in the ground hole, and finally the ground hole is poured with concrete.
  • a very big disadvantage in the known solution is the destruction of the natural strength of the soil by the necessary excavation of an earth hole for the manufacture of the foundation described.
  • the lost strength of the soil can essentially only be compensated for by an increased concrete mass.
  • a tubular anchoring section for steel masts or the like is known, which is driven into the ground and has an outer collar (flange) to increase the lateral stability, which rests on the surface of the earth when the anchoring section is driven.
  • the lower end of the same is with a closed tip Mistake.
  • the tubular anchoring section must be relatively slim in order to keep the resistance when driving into the ground within reasonable limits. Nevertheless, the earth resistance cone is very high, with the result that considerable forces have to act on the anchoring section in order to drive it into the ground. This is usually done using a monkey or bear. This method increases the risk of breakage for the anchoring section. Furthermore, it cannot be avoided that the hole in the ground that is created when hammering is knocked out or widened laterally, which inevitably has an effect on stability. For this reason, the mentioned outer collar is required, which has a considerably larger outer diameter compared to the outer diameter of the tubular anchoring section. Adequate lateral stability is only achieved through the oversized outer collar.
  • DE-GM 1 964 445 it is also known to produce a sheet steel or aluminum sheet To insert the mast into a tubular ground anchoring part made of concrete or plastic and previously buried in the ground. The strength of this mast anchoring is very limited and at most it is sufficient for light sheet metal masts.
  • the solution known from DE-GM 1 964 445 is completely unsuitable as a foundation for supporting pillars of assembly halls or bridge pillars.
  • the present invention has for its object to provide a foundation for masts, pillars, rails, or the like. That is characterized by the highest stability with little material and simple manufacture, especially in difficult terrain can be easily built.
  • the anchoring section of the foundation according to the invention is designed in such a way that it can be driven in by low, medium or high-frequency vibration without greater resistance.
  • the earth resistance cone is extremely low during driving, but in the fully driven state it is considerably higher than in the known constructions, so that a very high anchoring effect is achieved.
  • an anchoring section consisting of an approximately 3000 mm long hollow profile with a cross-sectional dimension of 600 x 600 mm and a weight of approximately 350 kg and a wall thickness of approximately 5 mm with a load (weight of the vibrator) of only approximately 2, Vibrate 5 tons into the ground. About 15 tons are required to pull the foundations out of the earth. The load capacity of such a foundation is around 25 tons, i.e. with a vertical load of over 25 tons, the foundation would sink further into the ground.
  • the anchoring section designed as a hollow profile is vibrated, the earth immediately adjacent to the wall of the anchoring section becomes quasi "flowing". As a result, the anchoring section penetrates the soil with relatively little resistance.
  • the earth immediately adjacent to the wall of the anchoring section solidifies practically abruptly, an additional hardening being achieved by the inner and optionally outer earth hardening element provided according to the invention.
  • the high earth resistance cone of the foundation according to the invention in the driven state is i.a. due to the highly solidified earth penetrating into the soil from below into the interior of the anchoring section during vibration, which gives the hollow profile a strength corresponding to a very strongly dimensioned solid body.
  • 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 construction according to the invention, but rather the mass formed by the hollow profile, the earth enclosed inside the same and the earth stabilization element (concrete insert or the like).
  • the mast or support pillar or the like is attached to the foundation according to the invention in such a way that the mast, support pillar or the like is located completely above the earth's surface, there is the possibility for the anchoring section (earth part) and the part arranged above the earth, that is Mast, support pillar or the like.
  • the anchoring section earth part
  • the mast or the like a material can be used 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 from the 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 are of course chosen for the anchoring section.
  • the ground stabilization element arranged in the interior of the hollow profile-like anchoring section preferably consists of a plate made of corrosion-resistant steel which is spaced from the upper end of the anchoring section and extends over the free inner cross section thereof.
  • This plate which can be closed or in the form of a close-meshed grid, is welded or screwed to the inside of the hollow profile-like anchoring section. In this construction, the soil penetrating into the interior of the anchoring section from below is solidified during the final phase of vibrating in.
  • an outer soil stabilization element can 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.
  • a very preferred embodiment of the invention is characterized in that the inner and / or outer ground stabilization element is weighted or weighted and is arranged to be longitudinally displaceable on the anchoring section of the foundation.
  • This is a constant Action of the soil stabilization element or elements on the soil in the immediate vicinity of the anchoring section for the entire duration of the vibration of the same in the soil. In this way, an additional consolidation of the soil beyond the natural strength is obtained.
  • the "flow property" of the soil in the immediate vicinity of the wall of the anchoring section which is preferably designed as a hollow profile, is practically not influenced by the ground stabilization elements.
  • the additional consolidation of the soil surrounding the anchoring section by the soil stabilization elements during the entire vibrating process results in extremely high stability of the foundation or the masts, piers or the like connected to the anchoring section of the foundation.
  • the lower edge of the anchoring section is preferably toothed.
  • the vibrating in in the vertical direction can additionally be overlaid by a rotational movement about the longitudinal axis of the anchoring section.
  • the anchoring section tapers slightly in the interior from bottom to top (3 ° - 8 °), while the outer surfaces extend parallel to one another. An additional compression of the soil penetrating into the interior of the anchoring section from below is thereby obtained during the vibration.
  • the outer surfaces thereof can be inclined slightly (3 ° - 8 °) from top to bottom towards the longitudinal axis of the anchoring section.
  • the ratio of (length of the anchoring section) to (outer diameter of a tubular anchoring section or 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): (200-1500 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 suitable, inter alia. also as a temporary support for heavy construction equipment, such as 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 guiding function of the separating cut in the concrete or asphalt ceiling for the anchoring section is also advantageous in the method according to claim 13 and the stabilizing effect of the concrete or asphalt surface around the anchoring section.
  • the foundation for a mast 1 consists of a hollow cylindrical anchoring section 2, which has been vibrated into the ground approximately vertically into the ground.
  • the mast 1 is flanged at the upper end of the anchoring section 2.
  • a steel plate 3 is welded into the hollow cylindrical anchoring section 2 at a distance from the upper end thereof, reinforcement angles 5 for increased strength being provided between the anchoring section 2 and the ground stabilization plate 3.
  • the ground stabilization plate 3 is in the driven state of the anchoring section 2, depending on the earth resistance, more or less far below the earth's surface. In any case, the described arrangement of the ground stabilization plate 3 ensures ground stabilization inside the anchoring section during the final phase of vibrating the same into the ground.
  • a ventilation opening 12 is provided just below the ground stabilization plate 3 in the side wall of the anchoring section 2.
  • the mast 1 lying above the surface of the earth is detachably fastened by means of screw bolts 10 to an upper end plate 13 of the foundation or anchoring section 2, a fastening flange 9 being provided for this purpose at the lower end of the mast 1.
  • the lower edge of the sleeve-shaped anchoring section 2 is toothed in order to facilitate driving or vibrating the same into the ground.
  • the anchoring section can simultaneously be rotated about its longitudinal axis.
  • the cross section of the anchoring section 2 can - as explained - also be rectangular, preferably square.
  • the edge length is approximately 200-1500 mm and the wall thickness is approximately 2-10 mm, preferably 3-6 mm.
  • Fig. 1 shows in the case of larger sheet thicknesses of the anchoring section 2 that instead of the ground stabilization plate 3, a concrete insert arranged in the upper region of the anchoring section 2 can be provided, which in the same way has an earth stabilizing effect during the final phase of driving in or vibrating.
  • the entire foundation according to FIG. 1, including soil stabilization plate 3 and possibly reinforcement plate 5, has a weight of approximately 100-2000 kg, depending on the length, cross section and plate thickness of the hollow profile-like anchoring section. It has been shown that, despite the very small wall thickness of the sleeve-shaped anchoring section, an extremely high rigidity and anchoring effect is achieved without additional reinforcements or the like.
  • the natural earth strength is not destroyed when the anchoring section used according to the invention is vibrated; it is even increased by the inner ground stabilization plate 3 and optionally by an additional outer ground stabilization element according to FIG. 2.
  • the outer ground stabilization element 4 is also slightly spaced from the upper end of the anchoring section 2.
  • the anchoring section 2 is a four square hollow profile with the same edge length.
  • 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 circumferential flange 6 and on the underside thereof welded angle plates 7, a total of 4 angle plates being provided which are arranged in the region of the center lines of the 4 sides of the hollow profile in such a way that they are evenly distributed over the circumference of the hollow profile .
  • the respective upper, horizontally extending legs of the angle plates 7 are welded to the underside of the peripheral flange 6, while the other, approximately vertically extending legs of the angle plates 7 are fastened, preferably also welded, to the outer lateral surface of the hollow profile or anchoring section 2.
  • the inner earth stabilization element in the form of a concrete insert 3 ' is arranged in the embodiment according to FIGS. 2 and 3 in the interior of the anchoring section 2 to be longitudinally displaceable so that it acts on the soil penetrating into the interior of the anchoring section 2 from below during the entire vibrating.
  • 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 serrated (4 serrations at the 4 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.
  • the anchoring sections 2 below the surface of the earth each consist of highly corrosion-resistant steel, for example chromium steel, which is also resistant to earth acids, etc.
  • the one above the ground Surface arranged mast 1 or the like Preferably consists of an air corrosion-resistant material, including wood.
  • the inner and optionally outer earth stabilization elements 3, 3 'and 4 have, in addition to their soil 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.
  • the foundation according to the invention is extremely stable against vibrations, bending stresses, and tensile and compressive loads.
  • the anchoring section 2 - and in the embodiment according to FIG. 1 the ground stabilization plate 3 - is 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 2 vibrates into the earth, cause it to rotate about the longitudinal axis. With this rotary movement the e.g. 1 serrated lower edge of the anchoring section 2 effective like a saw.
  • FIGS. 4 and 5 show particularly clearly the advantageousness of the foundation according to the invention.
  • Model tests have shown that the "earth resistance cone” when driving a slim pile into the ground is relatively large, ie it has a relatively large cone angle.
  • About the "earth resistance cone” of the hollow profile-like anchoring section 2 according to the present invention is very small when vibrating into the ground.
  • the hollow profile behaves like a knife-like cutting edge.
  • the anchoring section 2 has a very large "earth resistance cone", since the soil located in the interior of the hollow-section-like anchoring section 2 conveys to the anchoring section 2 the property of a solid body in the manner of a very thick pile (see illustration II in FIG 4).
  • the course of the earth resistance G of the two embodiments shown in FIG. 4 is shown in FIG. 5 over the penetration depth T.
