A ground mounting assembly includes one or a plurality of posts, each attached to at least one stabilizing plate or scoop pyramid. The post may be driven into the ground and then lifted to deploy plates into a locking mechanism, or driven into the ground by a pile driver with plate held in place, released, and driven further and deployed into a locking mechanism, or driven into the ground and double pounded inside the post to drive reinforcing plate into slotted winglets, or driven, double pounded and rotated to extend the reinforcing plates horizontally from the pole or pile. The post also can used as a mooring in harbors, lakes, or at sea. A system based on a double pounder pile driven mono pole, optionally extendable in length, is also described.

A pile driving assembly for installing a pile in an underwater bottom comprises a tubular pile and a hammer for driving the pile into an underwater bottom. The assembly is provided with a soil remover for removing soil inside the pile. The soil remover is located below the hammer and remote from a lower end of the pile in assembled operating condition.

The present invention provides a method for tackling the repelling of hammering during pipe pile driving, which is of simply structure and can be carried out easily. The technical scheme of the present invention comprises: When repelling of hammering occurs in the process of piling through a sand layer, drill holes downwardly around and/or inside the pipe pile, and jet high-pressure water to the sand layer below to cut and disturb the sand layer, which consequently decreases the soil resistance to the pipe pile and increases the driveability. The present invention is applied to geotechnical engineering.

A pipe assembly may have one or more pipe segments that are coupled together or coupled to a drive socket by a coupler. The bottom-most segment may have a body with a central axis, an exterior surface an upper end connectable to the pile assembly, a digging end, the digging end facilitating the creation of a borehole, and ports through which fluid is emittable. The bottom-most segment is designed to receive fluid introduced through the pipe assembly so that the fluid can facilitate the creation of a borehole and may be emitted through the ports during the driving of the pipe assembly into soil.

A ground mounting assembly, system and methods for ground mounting a structure include one or a plurality of posts, each of which are attached to at least one stabilizing plate. The posts may be at least partially positioned underground, with the stabilizing plates being buried to a depth of, for example, about 1 foot. Posts in a front portion of the mounting assembly optionally may be connected to an adjacent one of posts in a back portion of the assembly by a cross member. A ground mounted post that is driven them lifted to deploy uplift members. A ground mounting system based on a double pounder pile driven mono pole is also described.

A system for installing an array of pilings for an array of solar panels is highly accurate and efficient. The system includes a horizontal laser and a rotating vertical laser that are mounted on a first piling and aligned with a target on a second piling on the opposite side of the array. An alignment template is placed against a piling and aligned with the vertical rotating laser. The aligned template provides a designated location where the next piling is driven. A hammer target on the pile driver allows the installer to precisely install the next piling. After installation, the next piling is measured for accuracy and if errors are found, an alignment bracket is used to correct the error. The process is repeated until the array of pilings is complete.

There is disclosed a process for making a foundation system for a platform. In an embodiment, the process includes obtaining design data relating to load and soil characteristics; performing modal tests on a pile member installed in soil to determine natural frequency of the pile member; performing vibration tests on a pile member to determine stiffness; forming a model of using data obtained; testing, in silico, how the model responds to frequencies in a range of the equipment; adjusting, in silico, the model to satisfy design criteria; forming, in silico, a plan of a foundation system based on the adjusted model; installing the foundation system based on the plan; performing vibration tests on the installed foundation system, and measuring vibration levels; and adjusting the foundation system to avoid resonance at a natural frequency by one of stiffen vibrations or dampen vibrations. Other embodiments are also disclosed.

There is disclosed a foundation system for supporting equipment on a platform. In an embodiment, the foundation system is capable of harmonic resonation at a natural frequency due to movement of the equipment on the platform, the foundation system comprising one or more vertical pile members, each vertical pile member having a first end adapted to be driven into the ground and a second end adapted to be connected with a bottom portion of the skid platform; and one or more tunable pile members, each tunable pile member having a lower portion adapted to be driven into the ground and an upper portion adapted to be connected directly or indirectly with the skid platform, each tunable pile member adapted to receive an insert member between the upper and lower portions, so that the stiffness of the tunable pile member can be adjusted. Other embodiments are also disclosed.
摘要:
A pile is moved downwards by a movable part inside a piling apparatus. An apparatus body is fastened to the pile by fastening elements, during piling the movable part inside the apparatus body is moved downwards, the movable part is stopped hydraulically by medium in a cylinder space without the movable part striking the apparatus body. As the downwards directed motion of the movable part is stopped, the apparatus body and the pile fastened to it jerk downwards, after which, the movable part is moved hydraulically upwards. The counterforce of the motion affects the apparatus body and the pile fastened to it by pushing them downwards. The piling apparatus includes hydraulic cylinder cylinder to the piston of which the movable part is fastened, and to the hydraulic cylinder are connected a pressure transformer, a damping apparatus and a set of control valves to stop the movable part hydraulically.
