Definitions

  • the subject of the present invention is a method of constructing a reinforced concrete retaining pile which consists in driving a steel tube into the ground and filling it with concrete.
  • a threshing bell is used to beat the end of the tube to which a part has previously been fixed by screwing, making it possible to beat it and simultaneously drive it in step-by-step rotation.
  • the threshing bell represents a very heavy installation, of the order of 30 to 40 tonnes, constituting an important and expensive material, both with regard to purchase and depreciation as well as transport. To amortize the costs of setting up such an installation, it is necessary to build a relatively large number of piles in the same place.
  • the steel tube is also relatively very heavy, with thick walls, to resist beating and buckling.
  • Concrete piles are also known, HW system produced by means of a drill pipe recovered after the injection of concrete into the pipe.
  • the tube is driven in oscillation by means of a driving device placed on the head of the tube and actuated with compressed air.
  • This method also requires relatively heavy equipment and a height greater than the length of the longest tubes that it is desired to be able to drive.
  • the object of the present invention is to enable the construction of concrete piles by means of a light and very mobile installation, the installation costs of which are low, so that it can be used profitably on construction sites. medium and small. We also tried to simplify the operator's work and save time in the construction of a pile.
  • the method according to the invention is characterized in that the tube is driven in on the one hand by striking by means of a hydraulic hammer suspended in the tube, on a driving cone independent of the tube and on the other hand by driving the tube in rotation, that we remove the jacketing cone with the hammer, once the tube is pressed, that we introduce a reinforcement in the tube, that we pour concrete in the tube by gradually withdrawing the tube as and when filling the hole with concrete.
  • the rotational drive of the tube can be done at an intermediate point of the tube located at a low height above the ground, so that the necessary equipment can be reduced in size.
  • the jacking cone can be integral with the hammer and reusable or independent of the hammer and left at the bottom of the hole to prevent groundwater from going back into the hole.
  • the method according to the invention can be implemented with light means, preferably carried by a vehicle, the whole being arranged so that all the operations can be carried out on the ground or on the vehicle.
  • the invention also relates to an installation as defined by claim 6.
  • FIG. 1 schematically represents a vehicle 1 on which the installation is mounted.
  • This vehicle is of known type. Its four wheels are steerable and it is provided with four feet such as 2 and 3, mounted on a jack, to support the vehicle in the working position.
  • It comprises a central turret 4 carrying an arm 5 at the end of which is articulated the first element 6 of a telescopic arm further comprising two other arms 7 and 8 constituting a telescopic crane.
  • the turret 4 further carries a telescopic cylinder 9 whose end is articulated to the telescopic arm 6 to straighten it in the vertical position. respectively to bring it back to a horizontal position on a support 10.
  • the element 8 of the telescopic arm is provided with a head 11 to which a cable 12 is attached.
  • the first element 6 of the telescopic arm further carries a device 13 for driving the tube 14 in rotation and a device 15 for holding and guiding the tube.
  • the devices 13 and 15 can move with a certain stroke on the element 6, as will be described later in relation to FIGS. 3 to 5.
  • the lower end of the steel tube 14 is shown in Figure 2. Over its entire length, the tube is surrounded by a concrete iron 16 wound helically around the tube and welded to the tube. At the end in- f érieure of the tube is removably fixed a ring 17 is screwed as shown in the drawing, or by keying if one wants to avoid the risk of unscrewing when removing the tube.
  • This crown 17 carries a steel ring 18, free to rotate around the crown 17 and having an inner annular groove 19 by which it is retained axially on a heel 20 of the crown 17 with an axial clearance representing a certain working stroke.
  • the ring 18 has at its reinforced lower part an inner surface 21 against which abuts a circular surface 22 of a pointed driving cone 23 whose conical part extends the conical end 24 of the ring 18.
  • This driving cone 23 has an axial recess in which the striker 25 of a hydraulic hammer 26 engages, this striker being connected to the driving cone 23 by a key 27 passing through a lumen 28 of the striker 25.
  • the hydraulic hammer 26, known per se, is fed through the tube 14 by two pipes 29 and 30. It is provided with a ring 31 by which it is suspended from a hook 2 fixed to the end of the cable 12.
  • FIGS 3 to 5 show the detail of the means for holding and rotating the tube 14.
  • the rotating drive 13 comprises a ring 33 rotatably mounted between two brackets 34 and 35 by means of ball bearings.
  • the ring 33 is provided with a ring gear 36 meshing with the pinion 37 of a hydraulic motor 38 carried by the console 34.
  • the ring 33 carries eight small radial jacks 39 distributed around its circumference, jacks which serve to tighten the tube 14 for its rotational drive by the motor 38.
  • the brackets 34 and 35 are integral with a vertical plate 40 connecting two vertical tubes 41 and 42 of square section provided, near their upper ends, rollers 43, respectively 44 , guiding the tubes 41 and 42 in two rails 45 and 46 welded along the first element 6 of the telescopic arm.
  • the tubes 41 and 42 are mounted respectively around two hydraulic cylinders 47 and 48, the bodies of which are fixed to a cross-member 49 fixed to the inner end of the element 6 of the telescopic arm.
  • the ends of the piston rods 50 and 51 of these cylinders are fixed to the respective upper ends of the tubes 41 and 42 which are closed for this purpose by a plate.
  • the guide means 15 is constituted by a clamp fixed on a bar 52 connecting the tubes 41 and 42 near their upper end.
  • the tubes 41 and 42 and the devices 13 and 15 therefore constitute a movable assembly capable of moving along the element 6 of the telescopic arm with a stroke equal to the stroke of the jacks 47 and 48.
  • jacks also make it possible to lift the mobile assembly to release the tube 14 from the ground and to bring its end to the desired working height.
  • the element 6 of the telescopic arm is further provided with a retractable foot 63, for example constituted by a jack, so that the telescopic arm can bear on the ground.
  • FIGS. 6 to 11 The use of the installation will now be described in relation to FIGS. 6 to 11.
  • the support and drive means for the tube shown in FIGS. 1 to 5 have not been shown in these figures. .
  • the upper end of the tube 14 is closed by a cover 53 provided with a central hole for the passage of the cable 12 over which the cover can slide freely, the cable 12 being provided with a stop 54 making it possible to lift the cover when the cable 12 is pulled by means of the telescopic arm.
  • This cover 53 is also traversed by the supply conduits 29 and 30 of the hydraulic hammer 26.
  • the cover 53 further carries a curved pipe connection 55 at each end of which it is possible to fix a tube for supplying the concrete.
  • the tube 14 In the position shown in FIG. 6, the tube 14 is sinking into the ground 56.
  • the drive device 13 is first of all brought into its upper maximum position by means of the jacks 47 and 48.
  • the hammer 26 strikes the driving cone 23 opening the way to the tube 14.
  • the hits on the driving cone 23 must be transmitted to the crown 17.
  • the tube is rotated by the device 13 and it sinks into the ground by screwing the propeller 16 into the walls of the hole drilled by the driving cone 23. If this driving cone 23 advances faster than the tube 14, the ring 18 arrives at the end of its travel on the crown 17 and the hammer 26 strikes are then transmitted to the tube 14. As soon as this occurs the operator momentarily stops the hammer 26 so as to allow the tube to descend.
  • This stop could easily be automatically controlled by a detector fixed to the tube 14, for example on its inner face.
  • the tube 14 has a practical and transportable length, for example, 7 meters.
  • a practical and transportable length for example, 7 meters.
  • the hammer 26 and the driving cone 23 are removed and a second identical tube 14 'is fixed to the tube 14 which is connected to the tube 14 by means of a ring 57 fixed by keys in a manner known per se.
  • the tube 14 ′ is introduced into the devices 13 and 15, then the hammer 26 and its driving cone 23 are reintroduced to continue driving the tubes.
  • a reinforcement 58 (FIG. 9) is fitted into the tube 14, by means of the same hook 32, provided with a sheet metal cone 64 of diameter substantially equal to the inside diameter of the tube. tube 14 and intended to expel the water likely to be in the tube. It should be noted that the tube 14, respectively the tube 14 ', always has a part protruding from the ground which is clamped in the device 13.
  • the finished pile 65 is shown in FIG. 11.
  • the installation is particularly intended for driving tubes with a diameter of 340 mm, the ring 18 having a diameter of 400 mm.
  • the installation mounted on a vehicle is very mobile and is very quick to install.
  • Using a hydraulic hammer striking a jacking cone has proven to be much better than existing threshing and drilling installations.
  • the method and the installation also have the advantage of making it possible to prepare and fix a large length of assembled tubes, approximately 20 to 30 m, on the telescopic arm of the self-crane for the execution of the second pile and of the following piles on the same site, once the pile length has been established for this site.
  • the hammer 26 and the driving cone 23 can be reintroduced into the tube assembly, by its lower end, simply by removing the ring 17, these maneuvers being easy to execute.
  • the driving cone here consists of a cone 65 independent of the hydraulic hammer 26 and preferably of reinforced concrete for cost reasons.
  • This cone has a base with a diameter slightly larger than the inside diameter of the ring 18 so that it cannot go back up into the tube 14.
  • the cone 65 also comes to be housed in an internal flange 68 of the ring 18 in which it is retained and guided laterally.
  • the hydraulic hammer is integral with a cylindrical striking head 66 corresponding to the upper half of the driving cone 23 in FIG. 2 and provided with a range 22 'identical to the range 22 of the strike 2. This strike head 66 therefore drives the ring 18 by its reach 21 and it is removed with the hydraulic hammer 26.
  • the second solution consists in covering the driving cone 23 and the conical end 24 of the ring 18 with a conical steel cap 67 as shown in FIG. 2.
  • This cap 67 is pressed in with the driving cone 23 and the tube 14 and then remains at the bottom of the hole, somehow closing the end of the tube and preventing sufficient rise of the water in the tube.
