A method of rehabbing reinforced concrete pilings while in service and without the requirement to demo or otherwise gain access over the ends of an existing column. Design adopts modern environmentally responsible fiber reinforced polymer rebar and other FRP stirrups uniquely shaped into spiral sections requiring only side access for placement, designed to permanently encase the piling with a totally non-rusting non-metal reinforcement lateral containment cage featuring preformed circumference stirrups that mechanically interlock vertically and lateral adjustability to control density. The spiral stirrups extending fully 360-degrees around an existing piling with an additional overlap of at least 45 degrees.

The foundation system includes a below ground rigid raft foundation to bear a load for an above ground structure, and granular cushions and piles formed below the raft foundation. The granular cushions are configured for uniform load distribution of the raft foundation and the piles are configured to bear a load of the above ground structure and the raft foundation. The foundation system further includes stone columns encapsulated with a non-woven geofabric and configured to stabilize the raft foundation. The raft foundation is disposed adjacent and above the stone columns, the granular cushions are present between neighboring stone columns, and the granular cushions are present between the stone columns and the piles. The stone columns have a cementing agent for stabilization.

A retaining wall system includes a face panel having a first end beam and a second end beam extending in parallel to the first end beam. The face panel extends a height defined from the first end beam to the second end beam when the face panel is oriented in an upright position. The face panel further includes a backfill side and is configured to retain a backfill material on the backfill side of the face panel. The retaining wall system further includes a support leg having a bracket for receiving the first end beam therein and an extension platform transversely oriented to the height of the face panel when the first end beam is received within the bracket. The extension platform extends away from the bracket and is configured to anchor the face panel in the upright position.

Seal arrangement for a joint of two joint elements, in particular realized as a monopile and a transition piece, of an offshore structure, preferably an offshore wind energy installation, in particular a substructure thereof, in which, for the purpose of producing a stable joint, an upper joint element and a lower joint element are inserted into each other in a clamping manner by means of at least one seal unit, comprising one of the joint elements and the at least one seal unit fixed to the joint element, in such a manner that the seal unit, in a joining position, is arranged between an inner joint surface of one joint element and an outer joint surface of the other joint element, at least one seal unit having at least one elastic sealing element, which extends in the circumferential direction around the entire circumference and the thickness (D) of which is greater than the thickness (D) of an adjoining seal unit region and method for producing a seal arrangement.

Apparatus and associated methodology contemplating an excavation shoring apparatus, having a pipe sized to circumferentially enclose at least one human user working in a subterranean excavation. A plurality of channel brackets is attached to the pipe, each channel bracket forming an elongated cross-sectional profile defining a channel having a longitudinal axis extending along the channel bracket. The excavation shoring apparatus also has a plurality of selectively removable legs, each leg forming an elongated cross-sectional profile defining a beam. Each channel is configured to receivingly engage the beam in a closely-mating slidable relationship. The excavation shoring apparatus also has a plurality of removable fasteners, each connecting one of the legs to the respective channel bracket by simultaneously passing through an opening in the channel bracket and a selected opening of a plurality of openings in the leg. The selected opening in the leg corresponds to a desired position of the leg along the longitudinal axis.

An edge stabilization assembly for inclined surfaces having a synthetic tuft assembly; a water-permeable polymer mesh connected on one side of the synthetic tuft assembly, and a tuft-free non-permeable woven polymer mat connected on the other side of the synthetic tuft assembly, and a plurality of fasteners.

The present invention relates to an anti-erosion system made of geo-synthetic material, preferably of polysteel raw material (polypropylene (PP) and polyethylene (PE) mixture) instead of only polypropylene or polyester or nylon, resulting in a compromise between the mechanical properties of polypropylene, the chemical properties of polyethylene, and the good resistance to the environmental agents achieved through the incorporation of molecular chain stabilizers. The fraction of PP should range from 50% to 90% and the fraction of PE from 10% to 50%.

The present invention relates to an erosion control apparatus and methods of using and installing the apparatus. The apparatus is constructed to prevent erosion of soil during typical weather or tidal conditions and adverse weather events. The apparatus can include a plurality of anchored rolls and soil lifts operative to stabilize the shoreline.
