  • Patent number: 10859472
    Abstract: The present document relates to a piston corer for acquiring a soil sample. The piston corer comprises a sample reception cylinder for taking in and retaining the soil sample, and which comprises a piston. The piston is moveable over a piston stroke inside the sample reception cylinder. An intake opening at a first end of the sample reception cylinder allows to receive the soil sample upon penetration of the ground, and the piston is configured to move in a direction away from the intake opening during taking in of the soil sample towards an end position of the piston stroke. The piston corer further comprises an activator cooperating with a valve arranged for closing of the intake opening upon activation. The activator is configured for activating a closing action of the valve in response to the piston reaching the end position of the piston stroke. The document further relates to a method of acquiring a soil sample using such a piston corer.

  • Patent number: 7934568
    Abstract: A rock core removal method and apparatus allows efficient, safe, and reliable removal of a rock core sample. An inner collet tube and an outer ground tube, within a drill tube, protect the core sample during drilling. At depth, the collet tube is raised with respect to the ground tube so that the conical wall of the ground tube pushes constricting fingers on the collet tube inward, gripping the core sample within. The collet tube and ground tube are then raised, rotated, or raised and rotated, applying the necessary force to break the core sample off of the substrate. After retracting the tubes, the collet tube is lowered with respect to the ground tube to release the core sample. An ejection rod then pushes the core sample out of the collet tube. The ground tube may also act as the actuating means for a quick-change drill-bit release feature.

  • 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: 4606416
    Abstract: A core spring type core catcher and a full closure core catcher are completely concealed from the core within a coring tool. The full closure catcher is reliably actuated to assume a closed configuration without dependence upon gravity or an interference diametrical fit with the core by use of a cam ring which is longitudinally displaced downwardly within the core barrel by a preloaded compression spring. The full closure core catcher is comprised of a plurality of flapper valves circumferentially disposed outside of the inner tube and concealed by the inner tube or a terminal extension of the inner tube. Disposed above the plurality of flapper valves, and also circumferentially disposed outside of and concentric with the inner tube is a cam ring. Similarly circumferentially disposed outside of and concentric with the inner tube is a preloaded coil compression spring bearing against the cam ring. The cam ring in turn is in sliding contact with a rear surface of each one of the plurality of flapper valves.

  • Patent number: 4573539
    Abstract: A coring tool, which includes a flexible wire mesh in which the core is disposed, includes a mechanism for maintaining tension on the wire mesh sleeve which then seizes the core disposed within the sleeve, and which serves to retain the core and maintain it under tension. The sleeve is maintained under tension by tensile force transmitted to the sleeve through a stripper tube. The stripper tube is axially disposed through a piston ratchet assembly connected to a piston slidable within the drill string. The piston is resiliently urged upward within the drill string by a return spring but is longitudinally forced downward within the drill string and advanced downwardly with respect to the stripper tube by an increase in pressure within the drill string thereby compressing the return spring.

  • 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.

A cylindrical cutter placed around a boring mandrel attached to the operating rod of a jack is downwardly displaced only at the end of travel of the jack, driven into the ground with the boring mandrel and forms a cylindrical recess around the upper end of the bore-hole. The portion of soil which is trapped between the cylindrical cutter and the boring mandrel is removed automatically after simultaneous withdrawal of mandrel and cutter. A post can be driven into the bore-hole, cement or concrete being then poured into the cylindrical recess.
