  • Patent number: 5101917
    Abstract: An in-place soil sampler assembly includes an outer barrel or tube coupled to a corer point at one end thereof. An inner samping tube is contained within the outer tube. A soil sample retainer has a support ring connected to one end of the inner sampling tube. The support ring carries a plurality of flexible arcuate leaves each having a base portion secured to the ring and each having an apex moveable with respect to the support ring between opened and closed position. A collar is mounted at the end of the outer tube to form a cavity for receiving the soil sample retainer when the leaves are opened for passage of a soil sample from the corer point into the inner sampling tube; the leaves are closed when the support ring is removed from the cavity so as to form a convex soil sample support surface facing in the direction of the inner sampling tube for holding a soil sample therein.

  • Patent number: 4930587
    Abstract: A coring tool comprises a core cutting section and an actuating section disposed thereabove. The core cutting section includes axially telescoping outer and inner barrels. The inner barrel includes a jaw carrier which carries pivotable core-catching jaws normally covered along their radially inner sides by a driver sleeve. When the driver sleeve is raised by the actuator section the jaws are uncovered. Thereafter, the driver sleeve raises the jaw carrier to bring the jaws into contact with a stationary inclined jaw-deflecting surface to force the jaws laterally inwardly through the core. The actuator section relies upon fluid pressure to release for movement a vertically risible member which is mechanically lifted by a drill string to transmit vertical forces to the driver sleeve from a drill string.

  • Patent number: 4671367
    Abstract: A drilling attachment for a utility truck designed for digging pole holes for ordinary utility and telephone poles is disclosed herein. The attachment is intended to replace the auger portion of a conventional auger digger when it is necessary to drill through rock or other hard materials. The excavating method contemplated employs a three step process. First, a deep kerf is cut into the rock by a plurality of drill bits that are independently driven in a rotary/percussive manner while being rotated about the circumference of the kerf. The dust and rock fragments generated by this process are removed from the kerf by an air flushing/vacuum system, that also serves to cool the drill bits. Second, a hydraulic piston is inserted into the kerf and expanded, thereby applying a lateral force to the base of the resultant core causing it to break away from the surrounding rock. Finally an expandable plug is inserted into a pilot hole located at the center of the core.

  • Patent number: 4664205
    Abstract: An axial bore is defined throughout the hydraulic lift inner barrel. This axial bore is communicated with the interior of the inner tube thereby allowing the interior of the inner tube to be flushed prior to initiation of the coring operation. When the coring operation is begun, flow of drilling fluid to the interior of the inner tube is prevented by allowing a ball dropped within the drill string to seat within a plug through which the communicating axial bore is defined. Once the flow of drilling fluid to the interior of the inner tube is stopped, the coring operation can begin. After the coring operation is completed, a second ball is dropped and allowed to seat within an inner mandrel through which the axial bore of the coring tool is also defined. Once the axial bore of the inner mandrel is closed, drilling fluid is forced into an expansion chamber within a telescopic piston disposed circumferentially outside of the inner mandrel. The piston is connected to the inner tube.

  • Patent number: 4553613
    Abstract: An automatically operable hydraulic lift inner barrel is devised to lift the inner tube of the core barrel on a drill string. An inner mandrel is axially disposed within the outer tube of the coring tool. An outer piston which is selectively locked to the inner mandrel is telescopically and concentrically disposed about the inner mandrel. Fluid is selectively diverted from the outer tube into the inner mandrel and inside the outer piston. An inner locking piston within the inner mandrel responds to the hydraulic pressure to unlock the outer piston from the inner mandrel. The outer piston is then longitudinally displaced by the hydraulic pressure thereby lifting the inner tube which is connected to it. After the outer piston has moved a predetermined distance, the hydraulic pressure supplied to the inner mandrel and inside the outer piston reaches a second predetermined magnitude. Burst disks are then blown thereby relieving the hydraulic pressure within the outer piston inner mandrel.

  • Patent number: 4552229
    Abstract: A mechanism for catching and holding a core within an inner tube in a drill string includes a slidable core catcher and a full closure core catcher. The slidable core catcher is disposed within the inner tube and is coupled to an inner tube ring concentrically mounted on the outside of the inner tube. The inner tube ring and the slidable core catcher are connected to each other by means of a shear pin slidable within a slot defined in the inner tube. An outer tube ring is connected to the outer tube concentrically disposed about the inner tube. When the outer tube ring contacts the inner tube ring as the inner tube is lifted, the inner tube ring is moved downwardly with respect to the inner tube, thereby pulling the core catcher with it. As the core catcher moves downwardly it is compressed by an inside conical surface provided near the end of the inner tube. This serves to effectuate operation of the slideable core catcher.

  • Patent number: 4440240
    Abstract: The method of making holes in the soil includes driving a capsule into the oil by percussive action and filling the capsule with the soil. Then the driving of the capsule into the soil by percussive action is continued, with the soil passing therethrough. The capsule is then withdrawn from the hole, and the soil that has passed through the capsule is also removed from the hole, whereafter the soil is removed from the capsule itself. The apparatus for making holes, performing the disclosed method, comprises a capsule capable of receiving the soil therein, having an open soil intake end, its opposite end being a partly open one. The capsule incorporates a percussive mechanism.
