Definitions

  • ABSTRACT A method and a device for providing a hole in the soil, for example for forming a foundation element, an earth-retaining wall or a water-retaining wall or the like in the soil, wherein a hollow pipe open at the lower end is introduced into the soil and the earth penetrated into the pipe is removed from the pipe.
  • the removal of the earth from the pipe is effected by a pressure fluid which is supplied to the pipe near the lower end of the pipe, and which forces the earth in the pipe upwards as a column.
  • This invention relates to a method for providing a hole in the soil, for example for forming a foundation element, an earth-retaining wall or a water-retaining wall or the like in the soil, wherein a hollow pipe open at the lower end is introduced into the soil and the earth, which penetrates into the pipe is removed from the pipe; as well as to a device for applying said method.
  • the removal of the earth from the pipe is effected by a pressure fluid which is supplied to the pipe near the lower end of the pipe and which forces the earth in the pipe upwards as a column.
  • Compressed air, pressurized water or other pressurized fluid may be used as a pressure fluid.
  • the removal of the earth from the pipe is effected very rapidly, and the clearing of the earth emerging as a column at the top of the pipe may be carried out for example by deflecting this column laterally and dividing the earth into slices which leave the building site by truck or via a conveyor belt. Consequently the space taken up on the site by the earth to be removed is small and the abovedescribed method results in a clean operation.
  • the pipe may have a lower cutting edge the inner cross section of which is slightly less than the inner cross section ofthe pipe.
  • the advantage may be obtained that the earth, which is displaced by the pipe in consequence of its wall thickness, must deflect outwards and will be in contact with the outer surface of the pipe, which is of great importance since in this way the pressure fluid supplied to the pipe is prevented from flowing out of the pipe via its lower end and escaping upwards around the pipe.
  • this friction may be reduced by supplying a lubricant, such as for example a bentonite suspension, to the pipe near the lower end of the pipe during the introduction of the pipe into the soil, for which purpose the supply conduit for the pressure fluid may be used.
  • a lubricant such as for example a bentonite suspension
  • said lubricant can also be utilized as a pressure fluid and therefore, when the pipe has reached the required depth in the soil, it is possible to continue atonce the supply thereof but now under increased pressure.
  • This may be done for example by means of chemical injection, as is known per se for soil hardening so that a hard homogenous sealing layer is obtained.
  • a liquid under pressure is used as a pressure fluid
  • sheetlike sealing elements having a specific gravity which is lower than that of the liquid may be added to the liquid, in order to form a sealing layer. These sealing elements will collect and by mutual overlapping will constitute the sealing layer. It is for example possible to add small pieces of synthetic foil, such as polyvinyl chloride foil having a surface area of a few cm. to the liquid under pressure.
  • a further possibility for forming the sealing layer consists in supplying an emulsion to the pipe near its lower end, the carrier of said emulsion filtering out in the earth and the floating substances of said emulsion constituting the sealing layer.
  • the invention furthermore comprises a device for providing a hole in the soil by means of the aforedescribed method.
  • FIG. 1 is a vertical section of the lower portion of a first embodiment of the device according to the invention for providing a hole in the soil.
  • FIG. 2 is a vertical section of the lower portion of a modified embodiment of the device for providing a hole in the soil.
  • FIG. 3-7 show diagrammatically the various processing steps for forming an earth-retaining wall in adjacent holes in the soil which are successively provided with the device according to the invention.
  • holes are provided in the soil for many purposes, for example for soil testing, for drainage or lowering the water level and for forming foundation elements, such as piles or the like, or earth-retaining walls or water-retaining walls in the soil.
  • FIG. 1 shows a first embodiment of the device according to the invention for providing such holes in the soil.
  • This device comprises a hollow pipe 1, the cross section of which is cylindrical but may have any shape.
  • the pipe 1 comprises near its lower end at least one, but preferably several lateral inlet openings 2 each connected to a supply conduit 3 extending in upward direction immediately outside the pipe 1.
  • the pipe section 5 further comprises a lower portion 5" of reduced thickness, which connects via an exterior upwardly and outwardly slanting collar 6 to the likewise upwardly and outwardly slanting lower edge 6' of the pipe I and which ends at the lower end, via an upwardly and outwardly slanting lower edge 7, into a cutting edge 8, the inner cross section of which is slightly smaller than the inner cross section of the pipe I,
  • the pipe section 5 further comprises an upper end portion 5 of reduced thickness extending in upward direction from a collar 9, which fits against the inner surface of the pipe I and which extends horizontally a small distance below the inlet openings 2.
  • the upper end portion 5'' defines with the inner surface of the pipe 1 an annular space 10, open at the top, into which the inlet openings 2 end.
  • a distributor ring 11 is secured in said annular space 10, said ring 11 fitting externally of the inner surface of the pipe 1 and internally ofthe upper end portion 5, said ring 11 being provided with a plurality of passages 12 for the pressure fluid distributed along the periphery.
  • a valve 13 has been screwed from the top, said valve being constructed similar to a bicycle tire valve and cooperating with a rubber valve tube 14.
  • These valve tubes 14 end at about the same level as the upper end portion 5" of the pipe section 5.
  • a lubricant such as for instance a bentonite suspension
  • a bentonite suspension may be supplied via the supply conduits 3 to the annular space in the pipe 1, said lubricant passing through the valves 13 and bringing about an additional reduction of the friction between the inner wall of the pipe 1 and the earth entering this pipe 1.
  • a pressure fluid-for which purpose compressed air or a liquid under pressure may be used-is supplied via the supply conduits 3 to the lower ends ofthe pipe 1 and the earth contained in the pipe 1 is forced upwards as a column.
  • the direction of movement of the rising column of earth may be deflected and the earth may be divided into slices. Further, removal of this earth from the building site may be effected for example, by truck of conveyor belt or similar device.
  • FIG. 2 shows a modified embodiment of the device according to the invention for providing a hole in the soil.
  • a pipe section 15 having a cutting edge 8 at its lower end is secured to the pipe 1 by means of welding.
  • the lower portion 1 of the pipe 1 has the same inner cross section as the pipe piece 15, said inner cross section being slightly less than the cross section of the upper portion 1 of the pipe I.
  • an inner collar 16 of the pipe 1 slants inwards and downwards.
  • the inlet openings 2 are provided immediately above this collar 16 in the pipe I.
  • a support ring 17 is welded in the pipe portion 1 and has an inwardly and upwardly slanting upper edge 18 defining together with the collar 16 a groove of V-shaped cross section. This groove accommodates an end strap 19 of a cable 20 extending upwardly at the outside of the pipe 1 and passed through a pipe 21 which has been mounted on the outer wall of the pipe 1.
  • the upper end of the cable 20 is pulled, whereupon the end strap 19 cuts through the column of earth and forms a bottom surface at the earth in the pipe 1 and the pressure fluid-which subsequently is supplied via the supply conduits 3 to the pipe lmay immediately apply pressure on said bottom surface.
  • FIGS. 3-7 show diagrammatically the forming of an earthretaining wall in holes provided in the soil in the aforedescribed manner.
  • FIG. 3 a round pipe 22 has been brought into the soil by vibration down to the required depth whereupon the earth penetrated in said pipe 22 has been forced upwards by a pressure fluid.
  • FIG. 4 a second pipe 23 has been inserted into the soil while being vibrated, said second pipe having a flat substantially rectangular cross section and extending with a narrow side to the pipe 22, and the earth which penetrated into said pipe 23 may be removed in the manner described above.
  • FIG. 5 a reinforcement has been arranged in the pipe 22 and concrete has been poured whereupon the pipe 22 has been pulled out and under vibration has been driven again into the soil at the other side of the pipe 23, whereafter the earth which has penetrated into the pipe 22 is removed.
  • FIG. 6 a reinforcement has been arranged in the pipe 23 and concrete has been poured, whereafter the pipe 23 has been pulled out and while being vibrated has again been driven into the soil adjacent the pipe 22 but at an angle to its previous position whereupon the earth which has entered the pipe 23 has been removed.
  • a method for forming a hole in the ground comprising vertically introducing a hollow pipe which is open at its lower end from the surface of the earth into the earth to the ultimate depth of the hole, vibrating the pipe during such introduction into the earth, and removing the earth which has penetrated into the pipe only after the pipe has reached its ultimate depth by supplying a pressure fluid into said pipe near its lower end to force the earth in said pipe upwards as a solid mass the introduction of the pipe into the earth being achieved solely by the vibration and in the absence of supply of pressure fluid.
  • a method according to claim 2 comprising reducing the friction between the inner wall of the pipe and the earth contained in the pipe, prior to and/or during the time that said earth is forced upwards.
  • a method according to claim 2 comprising forming the lower end of the pipe with a cutting edge, the inner cross sec tion of which is slightly less than the inner cross section of the pipe.
  • a method according to claim 2, comprising vibrating the pipe during the time that the earth is forced upwards.
  • a method according to claim 2 comprising introducing a lubricant into the lower end of the pipe during the introduction ofthe pipe into the soil.
  • a method according to claim 1 comprising forming a sealing layer in the lower portion of the pipe above the point of supply of the pressure fluid prior to forcing the earth in the pipe upwards.
  • a method according to claim 6 comprising supplying an emulsion to the pipe near the lower end of said pipe, the floating substances of said emulsion constituting the sealing layer.
  • a method according to claim 1, comprising gradually reducing the supply pressure of the pressure fluid in the period during which the earth is forced upwards.
