Definitions
- the invention pertains to a driver for installing foundation elements, such as anchors or piles, in a ground formation and preferably in submerged condition, comprising a housing for accommodating and guiding a weight, an element for mounting the driver on or in a foundation element, one or more connectors for connecting the driver to a source of a high pressure gas or, preferably, one or more chambers for holding a charge, and corresponding conduits allowing a high pressure gas to flow from the chamber(s) or connector(s) to below the weight.
- the invention also relates to a kit of parts for assembling a driver and to a method of installing foundation elements.
- a hammer body is fixedly supported in axial alignment with the head of a pile that is to be driven and carries a reaction body guided for movement thereon in a direction that is axial to the pile.
- the hammer body and reaction body define opposed first and second ends of an expansion chamber.
- a pyrotechnic charge is initiated to create a rapidly expanding volume of high pressure gas in the expansion chamber to generate a downward pressure force pulse to drive the pile, an equal and opposite upward pressure force pulse being applied to the reaction body.
- a damping structure preferably a large volume container, operatively associated with the reaction body interacts with the water in which the tool is submerged using the inertia of the water to resist upward movement of reaction body.
- the reaction body When the reaction body has stopped moving upwards, it descends back to the start position and applies a secondary blow to the pile.
- the driver according to the present invention is characterised in that the housing is adapted to allow a stroke of the weight having a length such that, during upward movement of the weight (and downward movement of the foundation element), the pressure of the gas drops to a value, which will cause the weight to decelerate.
- the housing is adapted to allow a stroke of the weight of at least 2 meters, preferably at least 5 meters, more preferably at least 10 meters.
- the stroke of the weight will not be longer than 50 meters, preferably not longer than 25 meters. The stroke will depend on the pressure above the weight.
- the driver according to the invention can be equipped with a solid weight or, especially in a submerged condition, can use a liquid weight, typically (sea)water taken from the surroundings, as will be explained in more detail below.
- a liquid weight typically (sea)water taken from the surroundings, as will be explained in more detail below.
- the invention also relates to a kit of parts for assembling a driver for installing foundation elements, such as anchors or piles, in a ground formation and preferably in submerged condition, comprising two or more segments for assembling a housing of a selectable length for accommodating and guiding a weight, an element for mounting the assembled driver on or in a foundation element, and a section comprising one or more chambers for holding a charge and/or one or more connectors for connecting the driver to a source of a high pressure gas, and corresponding conduits allowing a high pressure gas to flow from the chamber(s) or connector(s) to below the weight. It is preferred that the total length of the segments is at least 2 meters, preferably at least 5 meters, more preferably at least 10 meters.
- the length of the tube and hence of the stroke of the impact weight can be adjusted on site and to local conditions. For instance, if the driver is to be used at a depth of two kilometres, i.e. at a surrounding pressure of approximately 200 bar, a relatively short tube will be sufficient to decelerate the impact weight.
- the invention further pertains to a method of installing foundation elements, such as anchors or piles, in a ground formation and preferably in submerged condition, by means of a driver comprising a housing for accommodating and guiding a weight, an element for mounting the driver on or in a foundation element, and a source for supplying a high pressure gas, such as a pyrotechnic charge, which method comprises the steps of mounting the driver on or in a foundation element, arranging a weight, such as a solid weight or water taken from the surroundings, in the housing, releasing high pressure from the source to below the weight, allowing the weight to rise (relative to the downward moving housing) and the gas to expand to such an extent that the pressure of the gas drops to value below the pressure over the weight.
- a driver comprising a housing for accommodating and guiding a weight, an element for mounting the driver on or in a foundation element, and a source for supplying a high pressure gas, such as a pyrotechnic charge
- a driver comprising a housing for accommodating
- US 4,060,139 relates to an underwater gas discharge type hammer with a gas reservoir into which expanded ram driving gas exhausts to avoid aeration of incoming water which surrounds the gas discharge device of the hammer.
- the gas reservoir is also arranged as a diving bell to minimize pressure changes under the hammer ram and thereby to maximize ram stroke and improve sharpness of ram impact on the hammer anvil.
- US 3,958,647 relates to a pile driver, which includes a cylindrical housing, a movable massive weight within the housing, an annular cylindrical thrust-transferring member defining a discharge chamber below this weight, and a movable driving head attached to this annular member, forming a thrust-transmitting assembly adapted to be engaged with the pile.
- Pressurized gas such as compressed air is discharged from a gas discharge apparatus, called an airgun located within the discharge chamber and provides two driving thrusts for each discharge.
- the released high-pressure gas which may be intermixed with water in the discharge chamber, is permitted to escape, thus allowing the massive weight to move downwardly.
- Figures 1A to 1C show respectively a side view, a cross-section and a detail of that cross-section of a preferred driver, comprising a solid impact weight and mounted on an anchor plate.
- Figures 2A to 2C show respectively a side view, a cross-section and a detail of that cross-section of the driver shown in Figures 1A to 1C, mounted inside a hollow pile.
- Figures 3A to 3C show respectively a side view, a cross-section and a detail of that cross-section of the driver shown in Figures 1A to 1C, using water as an impact weight.
- FIGS 1A to 1C show a preferred driver 1 for installing foundation elements, such as anchors or piles, in a ground formation.
- This driver 1 comprises a number of detachably connected elements, viz., from top to bottom, a housing 2 for control means, a tube 3 or tube-like body having a cylindrical bore 4, a power-pack 5, and a stabbing point 6 known in itself, with which the driver 1 is mounted on an anchor plate 7.
- the housing 2 comprises a trough-channel 2A, the bore 4 communicates directly with the surroundings of the driver 1.
- the tube 3 in turn comprises a plurality of detachably connected segments 8, in this case steel cylinders having an outer diameter preferably in a range of from 70 to 120 cm, e.g. 90 cm, a bore in a range of from 45 to 60 cm, e.g. 50 cm, and a length preferably in a range of from 2 to preferably no more than 12 m (so as to fit into a standard container), e.g. 6 m.
- Suitable means for detachably connecting the various elements and segments include, but are not limited to threaded connections, bayonet couplings, and flanges.
- the power-pack 5 comprises a central manifold 9 and upper and lower cylindrical wall portions 10, 11, each having an outer diameter, bore and wall thickness corresponding to those of the segments 8.
- Both wall portions 10, 11 contain a plurality of chambers 12 for holding a pyrotechnical charge 13, e.g. twelve chambers distributed equidistantly over the cross-section of the wall.
- a pyrotechnical charge 13 e.g. twelve chambers distributed equidistantly over the cross-section of the wall.
- the composition and size of each propellant charge can be adjusted as desired to provide the desired impulse shape (as to duration and magnitude) best suited to the geotechnical conditions at hand.
- the chambers 12 are cylindrical and extend parallel to the central axis 14 of the driver 1.
- Each chamber 12 is provided, at its end remote from the manifold 9, with an igniter 15, which is connected to the control means in the housing 2.
- the other end of each of the chambers 12 communicates, via a respective radially extending non-return valve 16, with a central bore 17 extending coaxially with the central axis 14 of the driver 1.
- a solid impact weight 18 which is made of e.g. forged steel, optionally provided with two gaskets 19 made of e.g. brass or plastic and allowing sufficient clearance for gas to slowly vent, and fits closely inside the bore 4.
- the anchor plate 7 and the driver 1 are attached to each other e.g. on the deck of a ship and by means of a steel cable, and lowered together. Subsequently, the anchor plate 7 is placed on a ground formation and the driver 1 is placed on top of the anchor plate 7 in a manner known in itself.
- a first charge 13 is ignited and resulting high-pressure gas flows from the respective chamber 12, through the respective non-return valve 16 to the central bore 17 below the impact weight 18. The expanding gas exerts and upward force on the impact weight 18, lifting the same, and a downward force on the stabbing point 6 and anchor 7.
- the length of the tube 3 has been selected such that the impact weight 18 can rise to a height at which the force exerted by the expanding gas below the impact weight 18 drops to a value, which is lower than the sum of the impact weight (in N) and the downward force exerted on the impact weight by the medium present above the impact weight.
- the impact weight 18 will decelerate. If the driver is used in submerged condition, e.g. two kilometres below sea level, the pressure in the surroundings will be approximately 200 bar and the height at which the impact weight starts to decelerate will be relatively small.
- the force exerted by the expanding gas below the impact weight 18 be allow to drop to a value, which corresponds to at least 1 G, preferably at least 2 Gs, more preferably at least 4 Gs of additional deceleration of the impact weight.
- additional deceleration can reach values of e.g. 20 Gs.
- the impact weight After the impact weight has come to a stop, it is accelerated by gravity and the pressure of the medium over the impact weight, thus compressing the gas below the weight and applying a second blow to the anchor.
- the driver 1 does not have a discharge valve for discharging the gas. Instead, the gas will gradually escape past the gaskets 19 and the weight 18, while the weight 18 oscillates inside the bore 4. When a sufficient amount of the gas has escaped, a second charge 13 is ignited and the above process is repeated until the anchor 17 has been installed at the desired depth in the ground formation.
- connection between the plate 7 and the driver 1 is cut e.g. by an ROV.
- FIGS 2A to 2C show a second driver 1, similar to the driver shown in Figures 1A to 1C, only mounted inside a hollow pile 20 and provided with a closed housing 2 on its top end thus defining a sealed gas compartment 21 above the weight 18.
- the gas compartment 21 effectively functions as a spring, i.e. the gas, for instance air, above the impact weight 18 is compressed as the gas below the weight 18 expands and the weight 18 rises. As a result, deceleration is further increased.
- FIGS 3A to 3B show a further preferred embodiment, especially suitable for use in a submerged condition.
- water is employed as an impact weight, i.e. the solid weight (18) is omitted and the bore 4 is filled with water typically taken from the surroundings.
- the driver 1 and the foundation element move downward and the water in the bore 4 is lifted to a height where of the pressure of the expanding gas drops to a pressure which is lower than the pressure of the surrounding water.
- the water will accelerate downwards applying a second blow.
- the gas will either escape directly via the descending water or part of the gas will be compressed and escape after a few oscillations of the water.
- the length of the tube 2 and hence the length of the stroke of the weight can be varied and, more specifically, adjusted to surrounding conditions.
- the length of the tube 3 is inversely proportionate to the water depth at which the driving is carried out.
