Addison L. Evans, Jr., Port Arthur, Tex., assignors to Bethlehem Steel Company, a corporation of Penn- Sylvania Filed May 14, 1958, Ser. No. 735,150 8 Claims. (Cl. 254-106) This invention relates generally to hydraulic jacking apparatus, and particularly to a step-wise actuated hydraulic jack for extending and driving or retracting a pile within a column in structures of the type used in subaqueous operations such as offshore drilling.
In such or similar operations, it is desirable to anchor the submerged structure firmly to the marine floor to prevent lateral movement or shifting of the structure along the bottom. V-arious means to attain this end have been proposed, and of these, piles are the most suitable in that they may serve several functions, viz., to prevent lateral shifting of the structure along the bot-tom, to support some of the vertical load, Iand to prevent overturning of the structure in hurricanes and the like, all by virtue of principles well known to those familiar with this art. In order to function effectively, these piles should desirably be of substantial length and crosssection. Accordingly, there is required powerful and foolproof means for extending and driving these piles well into the marine floor, a-nd for effectively withdrawi-ng these piles out of the marine floor.
It is one of the objects of our invention to provide positive and foolproof means for driving piles a considerable dist-ance into the marine oor.
It is another object of our invention toprovide positive and foolproof means for extracting piles from the marine oor.
. It is still ano/ther object of our invention to provide a step-wise actuated hydraulic jack for extending and driving and withdrawing piles from the ground, and particularly in association with structures used in subaqueous operations.
Other and further objects will appear during the course of the following description.
Referring to the accompanying drawings, in which like numerals represent like parts in the several views:
FIG. l represents a view in elevation of the hydraulic jack, push shaft and pile, lall located inside the hollow column. A base member is shown at the bottom of the column as typical of many structures used in subaqueous operations.
FIG. 2 represents Ian enlarged section in elevation of the hydraulic jack and push shaft, taken parallel to the two hydraulic cylinders. Y
FIG. 3 represents an enlarged section yin elevation of the hydraulic jack and push shaft, taken at `right angles to FIG. 2.
FIG. 4 represents an enlarged section in plan, taken along the line 4 4 of FIG. l, showing the hydraulic cylinders, push shaft, and lower holding pin.
FIG. 5 represents an enlarged section in plan, taken along the line 5-5 o-f FIG. l, showingthe push shaft, yoke, `and upper holding pin.
FIG. 6 represents an enlarged section in plan, taken along the :line 6 6 of FIG. l, showing an operating platform, the push shaft, and the hydraulic pumps operatively associated with the hydraulic cylinders.
Pile 1 is telescopically mounted inside hollow column 2 and extends through base member 3, being suitably guided therein by means not forming part of this invention and therefore not shown. It will be understood that base member 3 is shown herein las typical of many structurcs used in subaqueous operations, and is generally intended to comprise a ballastable pontoon which is floated to location and there submerged to the marine floor, and which may be refloated when desired. lIt should be further understood that this invention is applicable to those structures not having such base member 3.
Push shaft 4 is secured to pile 1, and extends upwardly in column 2. In the upper part of column 2, preferably at an elevation above any anticipated water level, is located :the jacking means comprising hydraulic cylinders 5, movable yoke 6, foundation 7, upper pin 8 slidably mounted in movable yoke 6 and lower pin 9 slidably mounted in foundation 7.
Foundation 7 is secured to column 2. Hydraulic cylinders S are secured at their lower ends to foundation 7, and at their upper ends are secured to column 2 through brackets 10. Motor-driven pumps 11, supported on platform 12 which is secured to column 2, supply hydraulic fluid under pressure through lines `1'3 or 14 to hydraulic cylinders 5, all in the well-known manner. Piston rods 15, operated by pistons 16, extend through movable yoke 6 and are fastened thereto by nuts 17.
Push shaft 4, preferably H-shaped in cross-section, extends through foundation 7, movable yoke 6 and platform 12. Pairs of guide plates 18, with registering perforations 19, are secured -to foundation 7 and movable yoke 6. The guide plates 18 of each pair thereof are spaced to receive the web of push shaft 4.
Air cylinder 20 is secured to movable yoke 6, and is operated by compressed air lines 21 or 22 to extend or retract upper pin 8 through or from perforation 23 of push shaft 4 `and perforations 19 of guide plates 18. Thus, when upper pin 8 is extended through perforation 23 of push shaft 4 and perforations 19 of guide plates 18, push shaft L4 is locked to movable yoke 6, and actuation of hydraulic cylinders 5 will raise or lower push shaft 4 and pile 1. When upper pin S is withdrawn from perforation 23 of push shaft 4, movable yoke 6 is independently movable with respect to push shaft 4 and pile 1.
Similarly, air cylinder 24 is secured to foundation 7, and is operated by compressed air lines 25 or 26 to extend or retract lower pin 9 through or from perforation 23 of push shaft 4 and perforation-is 19 of guide plates 18. Thus, when lower pin 9 is extended through perforation 23 of push shaft 4 and perforations 19 of guide plates 1S, push shaft 4 and pile l `are locked to column 2. And, when lower pin 9 is withdrawn from perforation 23 of push shaft 4, the latter and pile 1 are movable relative to column 2.
The spacing between adjacent perforations 23 in push shaft 4 preferably is equal to the stroke of hydraulic cylinders 5.
The operation of this jack to lower and drive pile 1 into the ground will now be described:
Assume that lower pin 9` is extended through a perforation 23 of push shaft l4. Movable yoke 6 is raised to the top of the stroke of hydraulic cylinders 5 at which point, if the preferred spacing of perforations 23 obtains, upper pin 8 will register with a perforation 23. Upper pin 8 is now extended into said perforation. Assuming at this point that the pile 1 is incapable of supporting its weight, the load is transferred from lower pin 9 to upper pin 8' by raising movable yoke 6 slightly. Lower pin 9 can now be removed from its perforation 23. Movable yoke 6 is then lowered to the bottom of the stroke of hydraulic cylinders 5 at which point lower pin 9 will register with a perforation 23 and is extended therethrough. Assuming at this point that pile 1 is still incapable of supporting its own weight, the load is transferred from upper pin 8 to lower pin 9' by lowering movable yoke 6 slightly. Upper pin 8 can now be removed from its perforation 23. Movable yoke 6 is raised to the top of the stroke of hydraulic cylinders 5, and the foregoing steps are repeated seriatim until the desired penetration is obtained. lt will be noted that when the pile has penetrated the ground sufficiently to support its own weight, it will not be required to raise or lower the movable yoke 6 slightly to transfer the load of the pile from one pin to the other. It will also be noted that the jack operates to drive the pile 1 into the ground against the weight of the structure comprising, inter alia, column l and base member 3.
The operation of extracting pile 1 from the ground is essentially the reverse of what has just been described. Assume that upper pin 8 is extended through a perforation 23, that lower pin l9` is withdrawn from a perforation 23, and that movable yoke 6 is at the bottom of its stroke. Movable yoke 6 is raised to the top of its stroke, carrying with it push shaft 4 and pile 1 and, at this point, lower pin 9 will register with a perforation 23 and is now extended therethrough. Upper pin 8 is retracted from its perforation 23, movable yoke 6 is lowered to the bottom of its stroke, and upper pin 8 is then reinserted in another perforation 23. This sequence is repeated seriatim until the pile is withdrawn. Again, when the pile is incapable of supporting its own weight, it will be required to raise or lower the movable yoke 6 slightly to transfer the load from one pin to the other.
We do not wish to be limited to the exact construction and operation shown and described, -but may use such substitutions, modifications or equivalents thereof as are embraced within the scope of our invention, or as pointed out in the claims.
