Furthermore, the present disclosure also regards a connection arrangement and a manufacturing method.

A pile lifting chuck including a chuck housing which is inserted into an inner diameter of a pile and has extension-installing pockets vertically formed at predetermined intervals to face each other in a radial direction. The pile lifting chuck further includes a pair of extensions which are disposed in the pockets and installed to be movable in the radial direction and a chucking cylinder which has one end connected to any one of the extensions and the other end connected to the other one of the extensions and which is configured to, by using a reaction force on the any one of the extensions, move the other one of the extensions to chuck the pile.

The present invention relates to a device for pushing four piles into the ground or into a seabed in a square configuration or in a diamond configuration, the device comprising: —a bridge assembly which defines a first, second, third and fourth connecting location arranged in a square or diamond configuration, —four connection assemblies via which in use each of the four piles is connected to the bridge assembly, wherein each pile connection assembly comprises: —an actuator comprising an upper actuator part and a lower actuator part, wherein the actuator is configured to extend, —a pile connector connected to the lower actuator part, —a control device configured for alternately letting each of the actuators extend, and configured for letting the pile which is pushed into the ground or seabed receive a greater force than the opposite pile of the square or diamond configuration, wherein the exerted push force is transferred into the bridge assembly and transferred at least partially from the bridge assembly as a tension force and a bending moment into the two adjoining piles via the two adjoining pile connection assemblies.

A system for holding a tubular sleeve (2) in a receiving structure during setting of a cement or other binder introduced in a fluid state between the sleeve (2) and the receiving structure, comprising:—at least one expandable structure (4) mounted on the sleeve (2), deformable from an inactive configuration allowing insertion of the sleeve (2) in the receiving structure to an active configuration immobilizing the sleeve (2) in the receiving structure,—at least one corresponding tool to be inserted in the sleeve (2), configured for acting on the expandable structure (4) to cause it to pass from the inactive configuration to the active configuration.

A micropile connection for supporting a vertical pile for a support system is disclosed herein. The micropile connection includes a base and two micropile sleeves attached thereto. The two micropile sleeves are configured to direct micropiles from opposing sides of the base across the base, such that the two micropiles cross through a vertical plane intersecting the base and between lateral edges of the base.

Embodiments of the present disclosure generally relate to a pumping unit base and methods for operating with the pumping unit base. The pumping unit base may include a plurality of driven piles installed in the ground, and a metal platform fixedly attached to the plurality of driven piles, wherein the metal platform is positioned above the ground. The metal platform may be removed from the driven piles and reinstalled to the driven piles.

The present invention relates to a device for pushing four piles into the ground or into a seabed in a square configuration or in a diamond configuration, the device comprising: —a bridge assembly which defines a first, second, third and fourth connecting location arranged in a square or diamond configuration, —four connection assemblies via which in use each of the four piles is connected to the bridge assembly, wherein each pile connection assembly comprises: ∘an actuator comprising an upper actuator part and a lower actuator part, wherein the actuator is configured to extend, ∘a pile connector connected to the lower actuator part, ∘a control device configured for alternately letting each of the actuators extend, and configured for letting the pile which is pushed into the ground or seabed receive a greater force than the opposite pile of the square or diamond configuration, wherein the exerted push force is transferred into the bridge assembly and transferred at least partially from the bridge assembly as a tension force and a bending moment into the two adjoining piles via the two adjoining pile connection assemblies.

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-driver assembly for driving a pile into the ground is disclosed. The assembly includes a casing defining a chamber configured to house a fluid; a positioning element configured to position the casing at or on the pile; and actuating means. Actuation of the actuating means displaces the chamber relative to the positioning element such that the chamber moves away from the pile to an elevated position. The actuating means is configured to release the chamber from the elevated position for displacement towards the pile such that a force is exerted by the chamber on the positioning member, to controllably drive the pile into the ground. The assembly further includes buffering means, the buffering means being configured to controllably buffer the force exerted by the chamber on the pile as the pile is driven into the ground. The buffering means is configured to rebound the chamber to a rebound position. Further actuation of the actuating means displaces the chamber relative to the positioning element, such that the chamber moves from the rebound position to the elevated position. A control system for controlling the pile-driver assembly and a method of driving a pile into ground using the pile-driver assembly are also disclosed.

A multi-function retaining structure for excavation and drainage operations during construction process and a method for excavation and implementation of a multi-function retaining structure at a target location. The multi-function retaining structure includes a first I-beam, a second I-beam, a third I-beam, a first inclined stiffener plate, and a second inclined stiffener plate. The method includes positioning the multi-function retaining structure above the target location, driving the multi-function retaining structure into the target location by pushing the bottom edge of the third web into the target location, softening soils in the target location by jetting water to the soils utilizing a first water jet tube and a second water jet tube, extracting the first water jet tube and the second water jet tube from the rectangular chamber, and draining water from the rectangular chamber by utilizing a water drainage pump and through a drainage tube.
