SHEET-FILING AND THE LIKE Jacques Desvaux, 17 Ave. du Colonel Bonnet, Paris, France, and Francois Berthet, 16 Rue Voltaire, Houilles, France Filed Nov. 20, 1961, Ser. No. 153,504 Claims priority, application France, Dec. 9, 1960, 846,425 1 Claim. (Cl. 173-49) The present invention relates to the driving and extraction of piles, sheet-piling, tubing and the like, and more especially to the technique known as self-driving, which consists in effecting the driving or extraction by means of anirnpulse device mounted directly on the pile or the like, without external Support.
In the U.S. Patents Nos. 2,942,427 and 3,008,528, there has been described a driving device of the kind referred to, in which the impulses obtained by means of an appropriate generator are converted to unidirectional percussions. These percussions are supplied in particular by means of eccentrically-weighted fly-wheels, and more precisely by the vertical or longitudinal component of the centrifugal force of fly-wheels rotating in synchronism, the other components balancing out in the horizontal or transverse direction.
Patent No. 3,008,528 has proposed the addition to the generator of alternating percussions of an elastic means such as a spring for the damping and the recuperation of the upward percussion for driving or the downward percussion for extraction, this spring-being placed between the percussion generator and the frame which is rigidly fixed to the pile.
In this way, devices have been constructed which ensure the driving of piles or the like and also their extraction, under good conditions of rapidity and effectiveness.
However, in certain cases for example, if the ground in which the pile is to be driven is or becomes too hard, or alternatively if the ground has too little resistance through the first fewmeters from the surface, or again in ground having very low lateral friction, it has been observed that the driving device had sometimes a tendency to rise between the percussions at the stage of upward movement of the impulse-generator fly-wheels.
This rising tendency which results in a slight upward movement of the pile between the working percussions, is undesirable. It eliminates or reduces contact of the point of the pile with the ground at the moment of the following percussion, which adversely affects the effectiveness and the efficiency of this latter percussion.
The present invention has for its object to obviate this disadvantage, while at the same time offering various advantages of application of the driving device.
It consists in providing the pile-driving or extraction device (for piles, sheet-piling, tubing or the like) with means which counteract, reduce or annul the effect of the forces directed in the sense opposite to that of the working percussions. In the case of vertical driving percussions, it .is the forces directed vertically upwards which are reduced or annulled; if the percussions are upward for extraction, it is the downwardly-directed forces which are counteracted. In the case where the percussions are directed obliquely or even horizontally, it is the oblique or horizontal longitudinal forces which are compensated.
A method of counteracting the forces acting in opposition to the percussions consists in providing the driving device with a supplementary elastic member, such as a spring, arranged between the pile or a frame fast with the pile and the impulse generator, in the zone and on the side where the working percussions are produced.
3,215,209 Patented Nov. 2, 1965 This supplementary elastic member acts in the direction opposite to that of the elastic damping and recuperation device for the upward impulses. It creates a downward action in opposition to the rising tendency. This action maintains contact of the working point of the pile with the ground at the bottom of the hole, and ensures that the percussions have their full effect. This supplementary elastic means has the further advantage of permitting the frequency of the percussions to be increased.
Another means of counteracting the forces acting in opposition to the working percussions consists in generat ing these percussions by means of several pairs of eccentrically-weighted fly-wheels balanced and synchronized in each pair, the pairs of fiy-wheels rotating at different speeds which are multiples of each other. In its most simple form, this means consists in utilizing two pairs of eccentrically-weighted fly-wheels, one of which rotates at twice the speed of the other. In this way, stronger impulses are obtained in one direction than in the other and in consequence, in the case of driving there is a predominance of the downward percussions over the upward forces and vice-versa in the case of extraction.
The two means previously defined can be put into use in combination, since their effects are advantageously additive both for the elimination of the undesirable lifting of the pile and for the increase of the frequency of the percussions and its adaptation to the nature of the ground being driven.
In particular, various arrangements, known or novel, of pairs of fly-wheels rotating at the same or different speeds may be provided. Thus, the pairs of fly-wheels may be disposed in the moving generator of the-driving device. It is however also possible, on condition that they are associated by an appropriate transmission, to place them partly on the moving generator and partly on the frame of the device. Or again they maybe mounted on separate moving generators which are suitably associated.
According to the invention, the device carrying into effect the foregoing arrangements comprises, as has already been explained, a generator of alternating impulses with the conversion of the impulses to percussions in one direction only.
The means employed for obtaining this conversion ensure, as has already been stated above, the production of a percussion force which is much greater than the force of the alternating impulses themselves before the said conversion.
Under these conditions, and if the motors which produce the alternating impulses are arranged in the generator itself and are rigidly fixed thereto, one of the faces of the generator being used to strike the pile or the frame which is rigidly fixed to it, the said motors are subjected by the percussion to considerable jerks or shocks resulting in particular from the setting-up of high-frequency vibrations at that moment in the pile and in the driving or extraction device which is rigidly fixed to it.
This is especially the case with the generator having eccentrically-weighted fly-wheels driven by hydraulic motors placed on' these fly-wheels in the body of the striking mass itself.
These jerks or shocks would be liable to damage these motors very rapidly. In this way, some motors have been put out of service after a few minutes of working of the devices in question.
According to the invention, there is then interposed between the portion of the generator which strikes the pile and that which comprises the motors, a dampingdevice, the characteristics of which, for example the thickness and the deformation in the case of a simple shockabsorber of rubber, are such that there is absorption of the high-frequency and high intensity oscillations or vibrations, without however any counteraction or even reduction of the transmission of the forces or blows at relatively-low frequency due to the percussions produced by the impulse generator.
The particular features and other advantages of the invention will be more fully described with reference to the accompanying drawings which show various forms -of embodiment, in comparison with the prior arrangement of which they are improvements.

FIG. 11 shows an alternative form of the shock-absorber.
In FIG. 1, there is shown a driving and extraction device in accordance with Patent No. 3,008,528, arranged for driving sheet-piling. This device comprises a frame 10, the lower portion 11 of which is arranged so as to engage the top of the upper portion of the sheetpiling 12. The piling 12 is gripped in the portion 11 by means of any appropriate clamping device 13, mechanical, pneumatic, hydraulic or other.
The impulse generator 14 is slidably mounted in the interior of the frame 10. This generator is for example of the type with two fly-wheels 15 having eccentric weights 16, rotating in opposite directions and synchronized. This generator is arranged so as to produce percussions which are transmitted by the hammer 17 to an anvil 18 carried by the lower portion 11 of the frame 10 and to the sheet-piling 12.
It should be observed that the assembly of the generator and its frame is mounted on the sheet piling 12 without any external support, following the technique known as self-driving referred to in Patent No. 2,942,- 427.
The generator 14 as shown in this case produces alternating impulses. It is preferably arranged so as to convert these impulses into unidirectional percussions, for example following the arrangement described in Patent No. 2,942,427.
In accordance with the provisions of Patent No. 3,008,528, one or a number of elastic elements, for example the springs 19, are interposed between the impulse generator 14 and the upper portion 20 of the frame 10. The tension of the spring or springs is regulated by means of jacks 21, it being possible to carry out this adjustment while working. The spring or springs19 have the efiect of storing the energy developed by the impulse generator 14 during its upward travel and restoring the energy on the downward travel, thus increasing the effect of percussions on the anvil 18 and on the sheet-piling 12. In addition, the spring or springs 19 permit the frequency of the oscillations of the generator 14 to be increased.
It will be recalled that for the extraction of the sheetpiling, the position of the spring or springs 19 is reversed, that is to say this spring is interposed between the generator 14 and the lower portion 11 of the frame,
working in the reverse sense, increasing the effect of the upward percussion.
With this device it has been found in certain cases, depending on the nature of the ground in which the driving of the sheet-piling is effected, that there is a slight tendency of the sheet-piling to lift, or at least there is a movement of its working point away from the bottom of the hole during the phase of upward movement of the eccentric weights 16. The assembly comprising the generator 14 and frame 11 is then liable to function as a vibrator, and the device loses its etfectiveness and exhibits a tendency to galloping.
The improvements according to the invention have the object of counteracting these effects by opposing, in the case of driving, the lifting effect with eventually a differential action of the alternating impulses, made predominant in the direction of the downward working percussions.
To this end, a first means consists, as shown in FIG. 2, in providing, in addition to the springs 19, between the generator and the upper portion 20 of the frame 10, a set of springs 22 between the generator 14 and the lower portion 11 of the frame 10.
With this arrangement, when the generator 14 is stopped, it is in equilibrium between the springs 19 and 22. These springs are calculated and arranged in such manner as to form in the stopped position as shown, a space 23 between the hammer 17 and the anvil 18. This space is determined in such manner that the beating of the hammer 17 on the anvil 18 takes place starting from a pre-determined speed of operation of the generator 14.
When the generator 14 is working, during the downward travel, the springs 19 play their usual part of restoration of energy, reinforcing the elfect of the percussion. At the same time however, the springs 22 are compressed, applying a downward thrust on the portion 11 and the sheet-piling, forcing the piling in the direction of driving.
During the upward movement of the generator 14, while the upwardly-directed impulse compresses the springs 19, the springs 22 expand and react on 11 to apply a downward action on the sheet-piling 12, thus maintaining it in the driving direction.
By means of the springs 22, it is also possible to-increase the frequency of the percussions to a greater degree than would be possible by the action of the springs 19 alone. If the springs have an increasing compression gradient, the oscillation frequency of the generator 14 increases as a function of the increase in compression of the springs 19 and 22.
The assembly comprised by the generator 14 and the springs 19 can be compared to a pendulum A (FIG. 3), oscillating between two springs B and C. It is known that the frequency of oscillation of the pendulum A thus arranged increases in proportion to the increase of the compression gradient of the springs B and C. The double set of springs 19 and 22 (FIG. 2), similar to the springs B and C of FIG. 3, ensure a greater increase in frequency.
By the double action of the springs 19 and 22, the operation of the driving device is thus improved. More regular percussions are obtained, irrespective of the depths reached and the nature of the ground encountered. All parasitic effects are avoided, in particular the jumping back of the sheet-piling. f
FIG. 2 and the foregoing explanations relate to the driving of the sheet-piling 12. It will be understood that for the extraction of the piling, the actions are reversed. In particular, the hammer 17 and the anvil 18 are then placed above the generator 14, and the springs 19 and 22 are interchanged in position.
A further means, which can be employed with that of the preceding embodiment of FIG. 2, but which can also be applied independently of the previous method, consists in equipping the driving device with an impulse generator comprising a number of sets of fly-wheels synchronized in each set, rotating at different speeds and supplying for that reason differentiated vertical actions, upwards and downwards.
An arrangement of this kind is shown in FIG. 4. The impulse generator 14a movably mounted on frame 10a comprises two sets of superposed fly- wheels 24 and 25. In each set, the fly-wheels are synchronized. One of the sets of fly-wheels, 24 for'example, rotates faster than the other set 25. These fly-wheels carry eccentric weights 26 and 27 respectively, having. appropriate masses and positions, in particular being so arranged that they coincide in the bottom positions when the eccentric Weights 27 .of the slower fly-wheels 25 reach the lower position. The fly- wheels 24 and 25 are associated by an appropriate transmission 36 comprising a rotating shaft having a bevel gearing at its ends.
By this means, a more powerful action is obtained in the downward direction than in the upward direction, as explained by the diagram ofFIG. 5. In this diagram, it has been assumed that the fiy wheels 24 are rotated twice as fast as the fiy-wheels 25. During the course of a cycle of rotation ofthe slowerfly-wheels 25, the assembly' passes through successive phases I, II, III, IV, V, the latter phase being identical with phase I and recommencing the cycle.
If F is the resultant of the vertical forces due to the fly-wheels 24 and f is the resultant of the vertical forces due to the fly-wheels 25, it can be seen that this resultant reaches F+f in the downward direction, but remains limited to F in the upward direction.
By a suitable choice of the masses of the weights 26 and 27, it is an easy matter to obtain f=F. The force is thus doubled in the driving direction without affecting the force in the upward direction. This results in an improvement of the effectiveness of the device.
According to a further form of embodiment shown in FIG. 6, in addition to the generator 14b with its flywheels 15b and eccentric weights 16b, the device comprises a second set of fly-wheels 28 with eccentric weights 29, this being mounted on the frame b. This second set of fly-wheels 28 is synchronized with the fly-wheels b by a conventional sliding or telescopic transmission 30 having bevel gearing at its ends and a splined connection intermediate its length by which the two sections of transmission 30 are enabled to have axial sliding movement relative to each other. However, the directions of rotation of the fly-wheels 28 are reversed wit-h respect to those of the fly-wheels 15b.
When the generator 14b moves upwards after -a percussion, it may have a tendency to lift the sheet-piling 12 by compressing the spring 19. The fly-wheels 28 oppose this tendency by pushing the sheet-piling 12 downwards. The two effects annul each other. At the following half period, the fly-wheels 29 will tend to lift the pile at the moment when the percussion of the generator 14b drives it. As the effect of percussion is considerably greater than the effect of the fly-wheels 28, the lifting tendency of the fly-wheels 28 has no effect.
FIG. 7 shows a further arrangement with two sets of fly-wheels rotating in opposite directions. In this arrangement, one of the sets of fly-wheels 15c is carried by the generator 140 as in the previous case. But the generator 14c, sliding in the frame 100, carries itself a frame 31 with slides, on which moves a further impulse generator 32 carrying the fly-Wheels 33 with eccentric weights 34. The fly-wheels 33 are synchronized with the flywheels 150 by a conventional sliding or telescopic transmission 35 similar to transmission 30 described above.
The fly wheels 33 and 15c rotate in opposite directions. The springs 19 and 22 of the previous examples are placed in this case on each side of the generator 32.
In this arrangement, the vertical component at every instant due to the generator 32 acts in opposition to that produced by the generator 14c. Any tendency of the sheet-piling to lift is thus eliminated, since no reaction of the generators is transmitted to it, with the exception of the percussion which takes place during one of the phases of the movement of the said generator 140.
In another phase of movement of the generator 14c, the latter tends to rise and its upward movement is counteracted by the effect of the generator 32, which has 6 the result of accelerating the movement of the generator downwards. This acceleration depends on the characteristics of the springs. At the moment of the percussion, the generator 32 obviously tends to lift the generator 140, but this tendency to lift, acting in a direction contrary to driving, has no effect since the force of the percussion blow is from 10 to 12 times greater than that of the centrifugal force developed by the generator 32, when the impulses produced by the generatorhave suit-: able lengths and frequencies.
This assembly is comparable. in a way, with two syn-. chronous pendulums D and E (FIG. 8) coupled together by a spring G. The frequencies of oscillation of this unit depend on the compression gradient of the spring G. The conditions of operation thus depend on the characteristics of the springs 19 and 22, which should be springs with a variable gradient.
In FIG. 9, there has been shown one of the possible arrangements of the shock-absorber placed, according to the invention, between the motor or motors 37 of the impulse generator and the portion of this generator which strikes the pile or the frame which is rigidly fixed thereto.
For the sake of clearness of the drawings and with the object of simplification, this shock-absorber has been shown applied to a device of the type illustrated in FIG. 1 above; it will however be obvious that it may be utilized with any one of the arrangements previously described.
In FIG. 9 can be seen the shock-absorber 38, which may be a suitable pad of rubber placed between the face 39 of the generator and the hammer 17d which also forms part of the said generator. In the arrangement considered here by way of example, the springs 19d are deformable metal-rubber elements stacked one on the other.
The pad 38 is of sufiicient thickness or has the required characteristics to intercept or deaden the high-frequency vibrations and abnormally-high shocks, Nevertheless, it should not flatten too much so as to avoid troublesome work and heating, and also to avoid damping of the shocks or percussions to be transmitted to the member which is being driven or extracted.
To this end, as shown in the diagram of FIG. 10, the rubber shock-absorber 38 is not only placed between the face 39 of the generator and the hammer 17d, but is also surrounded by the profile 40 of a part which is rigidly fixed to a part 39 or 17d of the assembly 39 and 17d. It is already in abutment against this profile 40 when the machine is stopped, as a result of the mechanical load and when so required, of a slight pre-stress. During the course of operation, its deformation 41-42 is controlled, the volume of expansion diminishing as the impulses or shocks increase, which are transmitted to the member to be driven or extracted.
A further arrangement in accordance with the invention is shown in FIG. 11. In this figure, the impulse generator with fiy-wheels 15e and eccentric Weights 16e comprises motors 37 fixed to the driving casings of the flywheels. An assembly comprising the guiding rods 1012 (replacing the frame 10 of the previous figures), the cross-beam 20a rigidly fixed to this rod, the lower portion He also serving as the anvil 18e is fixed to the sheetpiling 12 to be driven. A hammer or ram 17e, which is rigidly fixed to the generator 142 by means of a pneumatic or hydraulic belt 38e, replaces the pad 38 of FIG. 9. The said belt having limited and controlled deformations is remarkably effective and ensures the possibility of arranging the motors in the impulse generator, even if there is not provided between them and this generator an elastic coupling of any kind such as has always been proposed up to the present time.
It will be understood that the arrangements which have been described above have no limitative nature and may comprise all the alternative forms of construction, without thereby departing from the scope of the present invention.
