Soil displacement piles having a shaft and one or more soil displacement assemblies secured to the shaft are provided. If more than one soil displacement assembly is utilized, each soil displacement assembly is separated by a longitudinal distance. Each soil displacement assembly has an upper helical plate, a lower helical plate and separated from the upper helical plate by a longitudinal plate distance, and at least one soil displacement plate positioned relative to the shaft, the upper helical plate and the lower helical plate.

A pile driver driven foundation bracket system includes a foundation bracket drive unit and a foundation bracket unit. The foundation bracket drive unit includes a pile driving unit interface configured to engage with a pile driving unit, a hollow sleeve, and a foundation bracket drive interface. The pile driving unit interface is connected to a first end of the hollow sleeve, and the foundation bracket drive interface is connected to a second end of the hollow sleeve. The foundation bracket drive interface is removably connected to the foundation bracket unit. The foundation bracket unit includes a horizontal foundation bracket support arm, a foundation bracket brace having an opening, the opening being configured to allow soil to flow therethrough when the foundation bracket unit is rotated, and a foundation bracket hollow sleeve.

The invention provides a boring machine (10) for making a trench (T) in soil (S), the machine comprising a frame (12) that extends along a longitudinal direction (A), said frame (12) carrying a boring device (20) provided with four rotary boring members driven by four motors about axes of rotation that are stationary relative to one another.

A process for installing a modular retaining wall is illustrated and described having open or closed polygonal modules with channels disposed therein. The wall is set at least partially below a surface, the surface either being land-based or aqueous-based, and interfaces therebetween, e.g., shoreline. The modules of the wall are fastened to each other by respective fastening mating fasteners. The retaining wall is installed by a process employing a fluid-assisted internal mandrel.

A bulkhead protector apparatus is described. The protector is configured to be mounted within a cavity of the sheetpile of a bulkhead in order to prevent waves, wake, and debris from reaching the top portion of the bulkhead, minimizing damage and prolonging the life of the bulkhead. An angled waterguard portion is disposed within the cavity, and is configured to deflect water down and away from the top of the bulkhead. The waterguard portion is mounted to a whaler of the bulkhead via a planar mount portion which is secured to the underside of the whaler of the bulkhead via stainless steel lag bolts.

Disclosed is an attachment system for detachably coupling a female tube end and a male tube end to each other to form foundation piles. The system includes corresponding cylindrical sleeve holes in tube sleeves of the tube ends; a coupling element which is fittable in the sleeve holes and rotatable through an angle therein; a blocking pin on the coupling element or on one of the sleeve holes; and a blocking slot in one of the sleeve holes or in the base body, so that the blocking pin engages in the blocking slot upon rotation of the coupling element in the sleeve holes,

Additionally, one of the sleeve holes and the base body can be provided with corresponding sleeve slots in order to form a fitting hole together to fit a blocking element therein, in order to prevent rotation of the coupling element in the sleeve holes.
