- Such piling apparatus is known from GB-A-561,765.
- the piling apparatus according to above mentioned GB-A-561,765 shows, in operation, a substantially lower sound emission remaining below the maximum sound level allowed by law, so that this piling apparatus can also be used in densely populated areas.
- the tube is intended to remain permanently in the ground, together with the impact cap and the wedge-shaped segments, in order to be filled with concrete.
- the object of the present invention is to provide a piling apparatus of the above type, which, when pulled out of the tube takes along all parts necessary for transmitting the piling energy to the base plate and the inner tube wall.
- this object is realised by providing a piling apparatus wherein the tube at the lower end thereof in the vicinity of the base plate is provided with an inwardly thickened edge of slightly conical shape, while the wedge-shaped segments with their radially outwardly directed edges abut against said thickened edge, are pressed against the impact cap by means of at least two circular springs and suspended from the piling hammer, said hammer comprising a self-centring guide device, acting on the inner surface of the tube.
- the self-centring guide device preferably consists of a guide bush mounted on the upper end of the guide tube for the falling weight, over which a slide sleeve is slidable under spring pressure, while, further, a set of guide rollers are present, connected to the bush and the sleeve via pivotable arms, each of said guide rollers being capable of being pressed radially outwards against the inner wall of the tube by the spring pressure exerted on the sleeve.
- This self-centring guide device ensures that the piling energy is always transmitted centrically to the impact cap, also if the tube is to be driven into the ground not truly vertically but at an oblique angle.
- a slightly compressible ring is provided between the bottom plate and the end portion of the tube proximal to that bottom plate.
- Fig. 1 shows a piling tube 1, provided, at the lower end thereof, with a base plate 6 closing the piling tube 1, which base plate 6 is fitted loosely over the lower edge of the piling tube 1.
- the piling tube 1 is provided with an inwardly thickened edge 2 of conical shape.

- a set of arms 20 are mounted, evenly distributed along the circumference and pivotally connected to the guide bush 11. These arms 20 carry rollers 9, at the other end pivotally connected to the slide sleeve 10 via arms 21.
- cables 14 are slack
- the slide sleeve 10 is pressed in downward direction by the spring 12, as a result of which the rollers 9 will under pressure abut against the inner wall of the piling tube 1.
- the spring 12 should be dimensioned such that the outward forces acting on the rollers 9 are greater than the laterally directed component of the weight of the piling hammer when the piling tube 1 is oblique, so that in that case, too, the play between piling tube 1 and guide bush 5 remains present and the piling hammer is in a centred position in the piling tube 1.
- a piston/cylinder combination 22 for operating the falling weight 4, capable of being displaced in upward direction over, for instance, 1 meter and of subsequently falling freely on the impact cap 3.
- the piston/cylinder combination 22 is connected to a pressure line P and also to a return line R. Obviously, the falling weight 4 can also be displaced in upward direction in a different manner.

In this connection, it is important that the outflow of concrete 8 at the lower end of the tube is not obstructed by the thickened edge 2.
- this edge 2 facilitates the outflow of the concrete 8 and avoids the formation of a constriction in the concrete foundation pile, which in this manner acquires a diameter which is at least equal to the diameter of the piling tube.
- the oscillating movement of the piling tube 1, effected by the vibrator provides a thrust action on the concrete 8 that has already left the piling tube 1.

Description
- This invention relates to a piling apparatus for driving a tube closed at the lower end by a base plate into the ground to form a concrete foundation pile, which apparatus comprises
- a piling hammer with falling weight, provided within the tube and
- an impact cap resting in a centred position on the base plate, while between the conical impact cap and the lower edge of the tube, a set of wedge-shaped segments is provided, evenly distributed along the circumference for transmitting the piling energy produced by the falling weight to the base plate and the edge of the tube.
- Such piling apparatus is known from GB-A-561,765.
- From practice a piling apparatus has been known for many years, the piling hammer of which is positioned on the upper edge of the tube. The tube is driven thereby into the ground to reach the desired depth by means of a falling weight which is controllable in vertical direction. Subsequently, a reinforcement is provided in the tube and the tube is filled with concrete, after which the tube is withdrawn from the ground under vibration, using a vibrator.
- This method for manufacturing concrete foundation piles has proved to be highly reliable in a technical sense. Objections to this method have been raised on account of the fact that noise pollution is caused during piling, which amply exceeds the limits of environmental legislation, that is becoming more and more stringent. When piling blows are applied to the head of the tube, this tube will act as a resonance box, causing a sound emission that is environmentally unacceptable.
- The piling apparatus according to above mentioned GB-A-561,765 shows, in operation, a substantially lower sound emission remaining below the maximum sound level allowed by law, so that this piling apparatus can also be used in densely populated areas. However, the tube is intended to remain permanently in the ground, together with the impact cap and the wedge-shaped segments, in order to be filled with concrete.
- The object of the present invention is to provide a piling apparatus of the above type, which, when pulled out of the tube takes along all parts necessary for transmitting the piling energy to the base plate and the inner tube wall.
- According to the invention this object is realised by providing a piling apparatus wherein the tube at the lower end thereof in the vicinity of the base plate is provided with an inwardly thickened edge of slightly conical shape, while the wedge-shaped segments with their radially outwardly directed edges abut against said thickened edge, are pressed against the impact cap by means of at least two circular springs and suspended from the piling hammer, said hammer comprising a self-centring guide device, acting on the inner surface of the tube.
- The self-centring guide device preferably consists of a guide bush mounted on the upper end of the guide tube for the falling weight, over which a slide sleeve is slidable under spring pressure, while, further, a set of guide rollers are present, connected to the bush and the sleeve via pivotable arms, each of said guide rollers being capable of being pressed radially outwards against the inner wall of the tube by the spring pressure exerted on the sleeve.
- This self-centring guide device ensures that the piling energy is always transmitted centrically to the impact cap, also if the tube is to be driven into the ground not truly vertically but at an oblique angle.
- To ensure that the impact cap rests both on the thickened edge at the lower end of the tube and on the bottom plate, preferably a slightly compressible ring is provided between the bottom plate and the end portion of the tube proximal to that bottom plate.
- An embodiment of the piling apparatus according to the invention will be described in more detail with reference to the accompanying drawings. In these drawings:
- Fig. 1 shows the piling hammer according to the invention; and
- Fig. 2 shows the lower part of the piling apparatus in more detail, wherein the position of the impact cap during piling is shown in the left-hand section and the position thereof during withdrawal of the piling hammer from the tube is shown in the right-hand section.
-
- Fig. 1 shows a
piling tube 1, provided, at the lower end thereof, with abase plate 6 closing thepiling tube 1, whichbase plate 6 is fitted loosely over the lower edge of thepiling tube 1. At the lower end, thepiling tube 1 is provided with an inwardly thickenededge 2 of conical shape. Animpact cap 3 rests on the converging portion of thisedge 2, by intermediary of wedge-shaped segments 25 (see Fig. 2) which impactcap 3 further has a conical shape and rests by its lower face on the bottom of thebase plate 6. Located between thebottom plate 6 and the end portion of thetube 1 proximal to the bottom plate is a slightlycompressible ring 7, ensuring that theimpact cap 3 rests both on the converging portion of the thickenededge 2 and on the bottom of thebase plate 6. way of illustration, this is shown to an enlarged scale in the left and section of Fig. 2. - In addition to the
impact cap 3, the internal piling hammer comprises aguide tube 5 connected to the upper edge of theimpact cap 3, whichguide tube 5 accommodates a falling weight 4, slidable in vertical direction. At the upper end of the guide tube 5 a self-centring guide device is provided comprising aguide bush 11 connected to theguide tube 5, extending in upward direction and having, at the end portion thereof, a threadedpart 13 on which a nut/lock nut 17 is provided. Aslide sleeve 10 can be slid over theguide bush 11, which slidesleeve 10, at the upper end thereof, abuts against aspring 12, whose other end portion abuts against the nut/lock nut 17. Consequently, thespring 12 presses the slide sleeve in downward direction. Located at the lower end of theslide sleeve 10 is aring 16, also slidable over theguide bush 11 and to which a hair pin-shaped element 15 is connected, to which hair-pin shaped element ahoist cable 14 is attached. - On the outer surface of the guide bush 11 a set of
arms 20 are mounted, evenly distributed along the circumference and pivotally connected to theguide bush 11. Thesearms 20carry rollers 9, at the other end pivotally connected to theslide sleeve 10 viaarms 21. Whencables 14 are slack, theslide sleeve 10 is pressed in downward direction by thespring 12, as a result of which therollers 9 will under pressure abut against the inner wall of thepiling tube 1. Thespring 12 should be dimensioned such that the outward forces acting on therollers 9 are greater than the laterally directed component of the weight of the piling hammer when thepiling tube 1 is oblique, so that in that case, too, the play betweenpiling tube 1 andguide bush 5 remains present and the piling hammer is in a centred position in thepiling tube 1. - Located within the
guide tube 5 is a piston/cylinder combination 22 for operating the falling weight 4, capable of being displaced in upward direction over, for instance, 1 meter and of subsequently falling freely on theimpact cap 3. The piston/cylinder combination 22 is connected to a pressure line P and also to a return line R. Obviously, the falling weight 4 can also be displaced in upward direction in a different manner. - When the piling hammer is placed into the
piling tube 1, it is centred at the lower end thereof by the conical shape of theimpact cap 3 and at the upper end thereof by the outwardly pressedrollers 9 which abut against the inner wall of thepiling tube 1. When therope 14 is pulled for removing the piling hammer from thepiling tube 1, theslide sleeve 10 is slid in upward direction over theguide bush 11 by thering 16, whereby therollers 9 are released from the inner wall of thepiling tube 1. This facilitates the removal of the piling hammer from thepiling tube 1 considerably. - After the
piling tube 1 has been brought to a sufficient depth by means of the internal piling hammer, forinstance 20 meters below the ground level, the piling hammer is removed from thepiling tube 1 as indicated above and thepiling tube 1 can internally be provided with a reinforcement, after which the tube can be filled with concrete. Removal of the tube takes place by means of a vibrator, which is clamped around the upper end of the tube and is capable of bringing thepiling tube 1 into a vertically directed oscillating movement. In this connection, it is important that the outflow of concrete 8 at the lower end of the tube is not obstructed by the thickenededge 2. The diverging shape of thisedge 2 facilitates the outflow of the concrete 8 and avoids the formation of a constriction in the concrete foundation pile, which in this manner acquires a diameter which is at least equal to the diameter of the piling tube. Via the thickenededge 2, the oscillating movement of thepiling tube 1, effected by the vibrator, provides a thrust action on the concrete 8 that has already left thepiling tube 1. - Fig. 2 shows in more detail the lower part of the apparatus according to the invention. The thickened
edge 2 is of a slightly conical design, as indicated by the dotted line S in Fig. 2, indicating the extension of the inner wall of thepiling tube 1. Theimpact cap 3 is of conical design and between the outer wall of theimpact cap 3 and the thickened edge 2 a set of wedge-shaped segments 25 are provided, evenly distributed along the circumference of theimpact cap 3. The piling energy is transmitted via theimpact cap 3 to thebase plate 6 and via the wedge-shaped segments 25 to theedge 2 of thepiling tube 1. Thesegments 25 abut by the outwardly directed teeth thereof against the slightly conical inner face of thethicknened edge 2. Thesegments 25 are coupled to each other by means of twocircular springs 19, arranged at the upper and lower ends of thesegments 25. Thesesprings 19 keep thesegments 25 pressed against the wall of theimpact cap 3. In order to obtain a proper connection with theedge 2 of thepiling tube 1, the outwardly directededges 18 of the wedge-shaped segments 25 are provided with a rough, hardened surface. - Fig. 2 further shows a conventional coupling between the
guide tube 5 for the falling weight 4 and theimpact cap 3. Thetube 5, at the lower end thereof, is provided with aring 27, fixedly connected to thetube 5. The upper end of theimpact cap 3 is provided with a head of a diameter which is approximately equal to the inner diameter of thering 27. Positioned between thering 27 and theimpact cap 3 is a shock-damping ring 28, made of rubber. A series ofbolts 29, comprisingsprings 30, connect thetube 5 to theimpact cap 3. - When the falling weight 4 strikes the
impact cap 3, theimpact cap 3 can move in downward direction relative to the end portion of thetube 5, after which thetube 5 falls on theimpact cap 3 with some delay. When the piling hammer is removed from thepiling tube 1, thetube 5 is first displaced in upward direction and subsequently theimpact cap 3 is taken along via thebolts 29. At their upper ends, the wedge-shaped segments 25 are connected to thetube 5 viathin cables 26 and can consequently be taken along as well after theimpact cap 3 has been displaced upwards over some distance and thesegments 25 have moved radially inwards under the influence of thecircular springs 19.
