Definitions

  • the invention relates to a steel pile as defined in the preamble of claim 1.
  • a pile of this type is disclosed in document EP 0 342 138.
  • a passage system comprising a horizontally extending passage with downwardly directed passages extending therefrom is cut in a central web of the pile body, said passage system being covered on either side of the web by said two strip portions, with the exception of the lower end portions of said downwardly extending passages.
  • the lower end portions of the downwardly extending passages constitute transverse openings through the central web, through which, when driving the pile into the ground, fluid under pressure may enter laterally into the ground so as to improve lubrication of the pile surface on both sides and thereby facilitate driving of the pile into hard (rocky) grounds.
  • Driving of the pile is taking place by hammering.
  • the present invention aims at providing an improved pile, which is particularly suitable for driving into the ground by vibration.
  • the steel pile according to the invention has a "fluid injecting" pile foot that can be easily obtained by having said two strips extend below the lower edge of the web of the pile body.
  • the invention also relates to a method for driving a steel pile of the type above referred to into the ground by vibration, as defined in the preamble of claim 2.
  • the method according to the invention is characterized by the features mentioned in the second part of claim 2.
  • document GB 398 354 discloses a sheet pile, comprising a central fluid supply conduit that discharges in a pointed arch-shaped lower foot end of the pile. With this pile there is no horizontal fluid collecting and distributing passage from which fluid may enter into the ground during pile driving. With this well-known pile the fluid supply conduit may easily get blocked.
  • the invention provides a method as defined in claim 3.
  • DE-A 35 42 313 discloses a steel pile with a fluid discharging tube along the lower terminal edge of the pile body, from which tube a fluid, more particularly bentonite, is discharged through openings, which are directed upwardly and laterally. Moreover the well-known steel pile is said to be driven into the ground by vibration.
  • the steel pile used with the alternative method of the invention distinguishes from this well-known pile in that the fluid discharge openings are all directed in the substantially downward direction.
  • FIG. 1 two sheet piles 1 and 2 of a well-known trapezoid shape are diagrammatically shown.
  • the sheet pile 1 has already been driven at the desired depth whereas the sheet pile 2 has to be driven further into the ground.
  • the sheet piles 1 and 2 have their longitudinal edge formations in mutual engaging relationship as is well known in the art.
  • a relatively thick-walled steel tube 3 is attached, e.g. by welding, along the lower edge of the sheet piles 1 and 2.
  • Said tube 3 is provided with downwardly facing discharge openings 4.
  • the tube 3 is following the profile of the lower edge of the respective sheet pile and is connected to the lower end of a supply tube 5, which extends upwardly along the body of the respective sheet pile.
  • the supply tube 5 is connected with its upper end to a source of pressurized fluid (liquid), which is supplied through the supply tube 5 to the tube 3 along the lower edge of the sheet pile entering into the ground and is discharged from the latter tube through said openings 4.
  • a source of pressurized fluid liquid
  • the fluid supply While driving the sheet pile, by vibration or pushing, the fluid supply is controlled such that the discharging fluid brings the soil immediately below the lower edge of the sheet pile in a fluidized state.
  • the required fluid pressure may vary e.g. between 10 and 100 bar.
  • a central supply tube 5 is used and the tube 3 may have its ends closed.
  • the tube 3 could also be connected to a supply conduit provided in the so-called "lock space" along the free longitudinal edge formation (to the right in Fig. 1), which supply conduit would have to be removed prior to driving the next sheet pile.
  • a downwardly open collecting or pressure passage 3' is provided, which is confined by two strips 6 that are attached, e.g. by welding, on both sides of the lower portion of the respective sheet pile and is connected with a fluid supply conduit (5').
  • the strips 6 may be interconnected by bridging portions at regularly spaced locations.
  • the steel pile is in the form of a steel pipe 10, having a substantially circular tube 11 of reduced diameter fastened, e.g. welded, to its lower edge.
  • the circular tube 11 is provided with downwardly directed discharge openings 12.
  • the tube 11 may be in the form of two sections, which each cover a half of the circumference of the pipe 10 and are each connected with one end to the lower end of a supply conduit 13, that extends along the inner side of the pipe 10 upwardly, whereas the two sections 11a are closed at the opposite ends.
  • the supply conduits 13 are connected with their upper ends to a source of pressurized fluid (liquid), which is supplied through the supply conduits 13 to the tube sections 11a along the lower edge of the pipe 10 entering into the ground.
  • Driving of the pipe 10 is preferably effected by vibration. Especially with pipes of larger diameters less vibrating energy will be required for entering the pipe into the ground. It will be understood that a plurality of tube sections each connected to a supply conduit 13, may be used.
  • the steel pile is in the form of a H-profile 20, the lower edges at the foot of the profile being provided with fluid injection tubes 21 having discharge openings 22.
  • the injection tubes 21 are supplied with fluid through two supply conduits 23 on either side of the web of the H.
  • the profile shown in Fig. 4 may e.g. be used for making so called "Berliner" walls, with which between individual H-profiles horizontally extending beams of wood can be inserted.

Claims (3)

  1. Pieu en acier, adapté pour être enfoncé dans le sol et ayant le long d'au moins une partie de son bord terminal inférieur un élément formant bord épaissi qui comporte deux parties de bande (6) positionnées de chaque côté d'une partie d'âme du corps de pieu et formant, en association avec ladite partie d'âme, un passage de collecte et de distribution de fluide (3') qui est relié à un conduit d'alimentation en fluide (5') qui s'étend le long du corps de pieu vers le bas, passage à partir duquel du fluide sous pression peut pénétrer dans le sol environnant pendant l'enfoncement du pieu, caractérisé en ce que lesdites deux parties de bande (6) s'étendent vers le bas au-delà de la partie d'âme respective, de manière à former ledit passage sous la forme d'un canal dirigé sensiblement vers le bas situé entre lesdites deux bandes en dessous du bord inférieur de ladite partie d'âme.
