The present invention enables easy construction of a foundation pile having a rigid structure even at a site where a pile produced in a factory cannot be brought in. The tube 1 having a forming material filling port 1a at a top end and a closed bottom 1b at a bottom end is set in a suspended state, and foundation pile forming material 4 is filled from the forming material filling port 1a into the tube 1 in the suspended state. A composite foundation pile 5 in which the tube 1 and the filled forming material 4 are integrated is formed, and the composite foundation pile 5 is driven into the ground 13 or inserted into a borehole 12 formed on the ground 13.

The present invention relates to an attachment for drilling and/or foundation work, in particular a casing oscillator or casing rotator, comprising a receiving apparatus for clamping at least one pipe and a drive for generating a rotational movement of the clamped pipe, wherein the attachment comprises at least one integral control unit for an independent carrying out of control functions of the attachment.

A post-tensioned tube foundation for supporting a structure subject to high upset forces is described herein. The post-tensioned tube foundation includes an outer CMP, an inner CMP, and a tubular concrete base positioned between the inner CMP and the outer CMP. The outer CMP includes an inner surface that defines a cavity extending between a first open end and an opposite second open end. The outer CMP is positioned within an excavated hole defined along a ground surface. The inner CMP is positioned within the cavity of the outer CMP such that an annular space is defined between the inner CMP and the outer CMP. The tubular concrete base is positioned within the annular space defined between the inner CMP and the outer CMP. A plurality of bracing beams extend radially outwardly from the tubular concrete base.

A retaining wall can include wall blocks positioned to retain material against a rear side of the wall blocks. A method for supporting such a retaining wall method includes attaching at least one of the wall blocks to at least one ground-stabilizing base body supporting the wall blocks. The ground-stabilizing base body can include a flexible cable attached to the rear side of at least one of the wall blocks and to a portion extending rearward away from the rear side of at least one of the wall blocks.

Certain exemplary embodiments can provide a system comprising a frame, which comprises an outer mast and an inner mast. The outer mast slides along the inner mast. A motor is coupled to the frame. A hydraulic system is coupled to the motor. A jackhammer head is coupled to the outer mast, which outer mast allows the jackhammer head to float up and down on the inner mast as the jackhammer head reciprocates. Thereby vibrations from jackhammer motion substantially do not get transferred to the frame.

A fence installation apparatus that is operably coupled to a vehicle wherein the vehicle is traversed along a desired fence line while the fence apparatus is utilized to provide installation of a fence. The fence installation apparatus includes a drive assembly support frame having a rear support member and front support member. The rear support member and the front support member having operably coupled thereto a first drive member and a second drive member. The first drive member and second drive member are configured to drive fence posts into the ground. The fence installation apparatus further includes a first wire dispenser that is rotatably mounted in order to provide distribution of a wire during fence installation. A second wire dispenser is further included to dispense a second wire and further has a pole mount and pole member coupled thereto for distribution of fence accessories.

A method for constructing a building on a water-body. The method includes piling a plurality of piles on a bed of the water-body for laying a foundation for the building. The method further includes marking a reference-mark on each of the plurality of piles at a predefined-distance from a surface of the water-body. The method also includes cutting each of the plurality of piles along the reference-mark. The method further comprises installing a first pile-cap, having a plurality of guiding elements extending therefrom, over a first set of piles of the plurality of piles. The method also comprises installing a second pile-cap over a second set of piles of the plurality of piles.
