20100322716 | CAISSON STRUCTURES FOR UNDERGROUND SOIL BLOCKING AND MANUFACTURING METHOD OF ANTI-NOISE NON-VIBRATION CAISSON STRUCTURES USING THEREOF - As described above, the caisson structure according to the present invention is robotized to be moved up and down by itself, and thus there is no need of using large-size constructive machines such as cranes that are used in the existing construction methods, and has an effect of improving capability of structures for underground soil blocking against a lateral force since connections and engagement among inter-lateral-side iron rods or reinforced iron members are continuously integrated all over the four surfaces, which has been weak in a bored piling construction method and a continuous wall construction method such as an SCW (Soil Cement Wall) construction method or CIP (Cast-In Placed Pile) construction method, and this significantly reduces usage of internal reinforcement materials for supporting beams, thus saving costs of construction. Also, the strength and stability of a structure against the lateral force of the inter-lateral-sides, thus leading to a significant lowering in safety accidents such as collapse or upset of temporary structures for soil blocking. | 12-23-2010 |
20110081208 | AUTOMATICALLY ADJUSTABLE CAISSON CLAMP - A clamp system for operatively connecting a vibratory device to a plurality of caissons defining at least first and second diameters comprises a structural member, first and second clamps comprising first and second lock systems, respectively, and a clamp displacement system. The first and second clamps are supported by the structural member. The first and second lock systems fix the first and second clamps relative to the structural member. The clamp displacement system comprises at least one clamp displacement motor supported by the structural member and a mechanical link assembly connected between the at least one clamp displacement motor and the first and second clamps. Operation of the at least one clamp displacement motor allows the first and second clamps to be remotely displaced relative to the structural member such that the first and second clamps are spaced along the structural member as appropriate for either of the first and second diameters. Operation of the first and second locks systems fixes the first and second clamps relative to the structural member. | 04-07-2011 |
20110243668 | INTERNAL PIPE CLAMP - A clamp system includes a frame, a plurality of clamp members, an actuator collar, and an actuator system. The frame includes an attachment member and a stop ring defining a stop cam surface. The clamp members each define first and second cam surfaces. The actuator collar defines an actuator cam surface. The actuator system displaces the actuator collar. The frame supports the actuator collar and the plurality of clamp members such that the first cam surfaces engage the actuator cam surface and the second cam surfaces engage the stop cam surface. Operation of the actuator system displaces the actuator collar towards the stop ring. As the actuator collar moves towards the stop ring, the actuator cam surface acts on the first cam surfaces and the stop cam surface acts on the second cam surfaces such that the clamp members place the clamp system in an engaged configuration. | 10-06-2011 |
20130272801 | STEEL PIPE PILE AND STEEL PIPE PILE IMPLEMENTATION METHOD - Since the distal backside is provided on a rear side of a wing edge in an entering direction, when a steel pipe pile is rotationally driven into the ground, the distal backside resists against the rotation moment with the wing edge at the center. Thus, while avoiding the off-centered movement of the steel pipe pile and ensuring linearity, the steel pipe pile can be penetrated into the ground. Further, since a slanted opening is provided at a front side of the wing edge in the entering direction, soil excavated in accordance with the rotational drive into the ground can be smoothly introduced into the steel pipe pile body through the slanted opening. Thus, while restraining the ground resistance in accordance with the entering, the soil introduced into the steel pipe pile body can be pushed upward, thereby reducing an increase in the penetration resistance caused by clogging within the pipe. | 10-17-2013 |
20130279992 | EXTENSIBLE SHELLS AND RELATED METHODS FOR CONSTRUCTING A SUPPORT PIER - Extensible shells and related methods for constructing a support pier are disclosed. A shell can define an interior for holding granular construction material and define an opening for receiving the granular construction material into the interior. The shell can be flexible such that the shell expands when granular construction material is compacted in the interior of the shell. A method may include positioning the shell in the ground and filling at least a portion of the interior of the shell with the granular construction material. The granular construction material may be compacted in the interior of the shell to form a support pier. | 10-24-2013 |
20130294843 | HELICAL DRILL BIT FOR AN AUGER OF A GROUND EXCAVATION ASSEMBLY, IN PARTICULAR FOR BUILDING EXCAVATED PILES, AND DRILLING METHOD THAT USES SUCH A BIT - The helical drill bit defines a helical end section of a helical structure formed at its periphery by an auger of an excavation assembly, and it is associated or associate with a support portion of the auger. Such a support portion defines a proximal section of the helical structure, which has an extension substantially centred around a longitudinal axis (X-X). The helical drill bit is adapted to rotate about the longitudinal axis (X-X) together with the support portion so as to drill a hole in the ground. The helical end section extends around an extremity axis (Y-Y; Ψ-Ψ) that is not aligned relative to the longitudinal axis (X-X). | 11-07-2013 |
20140056652 | APPARATUS AND METHODS FOR PIPE PILING PLACEMENT - A pipe assembly may have one or more pipe segments that are coupled together or coupled to a drive socket by a coupler. The coupler may have a body with a generally tubular shape with an interior surface and an exterior surface. First and second flanges may extend outward from the exterior surface to engage the drive socket, thereby providing enhanced stability and coaxiality. The interior surface may have an upper receiving feature that can receive the bottom end of an overhead pipe segment, and a lower receiving feature that can receive the top end of a subtending pipe segment. The upper receiving feature may have an upper threaded bore with a lead-in portion that facilitates alignment of the overhead pipe segment with the upper threaded bore. The interior surface may also have a stop feature that prevents over-insertion of the top end and/or the bottom end into the coupler. | 02-27-2014 |
20140086693 | PILE WITH LOW NOISE GENERATION DURING DRIVING - A pile with a low effective Poisson's ratio is disclosed, which greatly reduces the sound coupling to the water and sediment or other ground when driving piles. In some embodiments the pile includes geometric features that reduce the radial amplitude of the compression wave generated during hammering by providing a space for circumferential expansion along the length of the pile. The geometric features may comprise slots and/or grooves. In an embodiment, a driving shoe has a perimeter that extends beyond the pile tube such that the sediment produces less of a binding force on the pile. The pile may be formed as a double-shelled pile with either or both shells having effective low Poisson's ratio properties. A bubble generating plenum may be attached to the shoe to further reduce friction during installation. | 03-27-2014 |
