The present disclosure relates to a vibro-hammer 1 connected to heavy construction equipment, and more particularly, a vibro-hammer 1 having a side grip in which vibrations are prevented from being transmitted to a connected heavy equipment machine to avoid a problem such as a change in a perforation position, the vibro-hammer 1 is firmly connected to a perforated pile to transmit vibrations generated in a gear box to the perforated pile through the side grip and improve workability, arms are gear-coupled to each other to prevent the arms and the side grip from being released from each other due to frequent vibrations, a pair of arms and the side grip can come into close contact with the perforated pile or separated from the performed pile by a single cylinder, the side grip can be easily replaced according a shape of the perforated pile, and applicability and workability is improved.

A construction machine for special civil engineering, includes a leader on which an advancing carriage is guided, which carriage has a holder for a work device, in particular a drilling implement or pile-driving implement, and which carriage is connected with a first drive, by way of which it can be moved along the leader. An additional auxiliary carriage is arranged on the leader, which carriage can be moved along the leader by way of a second drive, wherein at least one actuator and/or at least one sensor is/are arranged on the auxiliary carriage.

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.

Basement shoring apparatus has a modular panel having a panel body having a plurality of parallel drill rod shafts therethrough. Each drill rod shaft has a respective drill rod rotatably engaged therein. Each drill rod extends from a lower edge of the panel body and has a respective auger or cutting head attached at a distal end thereof. Each drill rod is connectable via an upper edge of the panel body for turning. Adjacent drill rods extend to different extent such that blades of respective augers overlap adjacently. As such, modular panel can be drilled into the ground to form shoring wall.

A shock absorbing apparatus (suppressor) for a vibratory pile driver includes three suppressor sections, including a first section adapted and arranged to absorb a load up to a selected amount. A second suppressor section is adapted to absorb a load above the first shock-absorbing section, with a third suppressor system providing a transition between first and second suppressor action as load increases.

A rotary driver 1 for a helical pile foundation 2 attached to a boom arm 3 of an excavator 5 forming a counter-support is described by means of which the helical pile foundation 2 can be screwed into or out of the ground in a defined direction. The rotary driver 1 is supplied by the excavator 5 with appropriate power, preferably hydraulic power, and is arranged at the front end of the boom arm 3 of the excavator 5. A rotary drive 6 is provided for this purpose at the front end of the boom arm 3 which transmits a drive torque 11 to the helical pile foundation 2, for which purpose a chucking device 7 for the helical pile foundation 2 is provided at the end of the rotary drive 6 facing toward the helical pile foundation 2. An additional counter-support 4 is arranged on the rotary drive 6, on the front end of the boom arm 3, or on the chucking device 7 and is anchored in the ground at the end opposite the area of arrangement. The additional counter-support 4 at least partially compensates for the forces acting on the helical pile foundation laterally to the plane of extension of the boom arm 3 due to the drive torque 11.

The present invention relates to a support structure for supporting a top structure, in particular a wind turbine, above the ground or a seabed, the support structure comprising: one single support pile having a length and a first outer diameter, the one single support pile comprising an upper part configured and intended to extend above the ground or the seabed, wherein the upper part of the support pile is configured to be connected to the top structure; a lower part configured to be in contact with the ground or seabed, wherein the support pile is configured to exert an upward vertical force on the top structure in order to carry the top structure; a plurality of foundation guides connected to the lower part of the single support pile, each foundation guide having an opening extending in a direction of the support pile.
