Abstract:
Armor units for rubble mound structures including breakwaters, revetments, groins, jetties, and the like. Embodiments are appropriate for ocean, river, lake and reservoir structure armoring, to prevent erosion from damaging hydrodynamic forces resulting from waves and water currents, and the like. An embodiment includes a central rectangular section, three “half H-shaped” appendages, optionally, one end frusta, and a flat bottom with two extrusions, nominally smaller than other appendages and frusta. An embodiment is symmetric about two perpendicularly intersecting vertical planes extending through the centroid of the unit. The three half H-shaped members are connected to outer parts of a side defined as the top and the two longitudinal sides of the central section. The three half H-shaped members comprise four-sided frusta that taper from a base at the central rectangular section to four-sided distal ends. For select embodiments, the frusta are generally symmetric.
Abstract:
A quay wall absorption block includes a back wall, a cap, and a half columnar wall extending between the back wall and cap. The half columnar wall defines a plurality of chamber surfaces and mating surfaces on opposite sides thereof such that the chamber surfaces define portions of a plurality of closed-end flow chambers on opposite sides of the half columnar wall when the mating surfaces are in contact with corresponding mating surfaces of other quay wall absorption blocks. The half columnar wall also defines a plurality of flow paths that extends therethrough to fluidly connect the plurality of closed-end flow chambers on opposite sides of the half columnar wall.
Abstract:
An energy dissipater comprising a plurality of periodic hyperbolic surfaces, forming a continuous surface-structure, and enveloping contiguous tunnels there through.
Abstract:
Disclosed is a removable erosion-control and fencing (“REAF”) system for shoreline preservation along a line defined by a plurality of posts. An exemplary REAF system comprises first and second post clamp pairs mounted to adjacent posts. Each post clamp pair “sandwiches” a post and is fixedly attached to the post by virtue of fasteners that lock one half of the post clamp pair to its other half. In this way, the post clamp pair “hugs” the post and is secured thereon without having to be permanently fixed to the post or damaging the structural rigidity of the post. Each post clamp pair includes a substantially vertical wall slot such that one or more cross-members may be received into the walls slots to form a wall section in a space defined between the adjacent posts.
Abstract:
A transportable wave suppressor and sediment collection system for suppressing wave action along the shore of a body of water, which includes a plurality of interconnected sections, each section including a base, a forward wall, and a rear wall, and having a plurality of flow pipes extending from the forward wall to the rear wall, and further including a plurality of shelves on the forward wall for dispersing wave energy, while redirecting and using the wave energy to allow water and sediment to flow into the flow pipes and for collecting sediment that is not carried into the flow pipes and settles on the shelves for being contacted by a following wave to carry the sediment into the flow pipes. In some deeper water embodiments, the sections may include a base portion, a top portion and one more spacer portions to enable raising or changing the height of the system.
Abstract:
A marine barrier has buoyant panels elastically connected with an included angle therebetween, to form a pleated row of panels with hinges arranged in first and second rows. An impact net having cables is attached to a net connection portion of each hinge in the first row. The net connection portions are attachable to the cables with a tension such that, when the barrier is floating and a moving vessel impacts the net, an impact force causes the cables to move relative to the net connection portions, transferring a portion of the force of the impact to the net connection portions, until cable stops on the cable ends engage net connection portions adjacent the cable stops. The force of the impact is then transferred to the panels, which engage the water to transfer the force of the impact to the water, to arrest the motion of the vessel.
Abstract:
A controlling system is used for controlling a state of a floating arrangement comprising plurality of containers, such as shipping or standard freight containers, especially consistent with ISO standard. At least some of the containers comprise a float arrangement having e.g. intra-container water-displacing volumes, such as an inflatable bag, which can be used for displacing water from the container when the inflatable bag is filled or for letting more water entering into the container when the inflatable bag is emptied, and thereby manipulating the buoyancy or draft of the container and thus also the same of the pontoon platform comprising said container(s). The state of the container and thus the floating arrangement can be controlled by operating the float arrangement by the controlling system, such as manipulating the inflatable bags or other state changing means of the float arrangement, such as propellers or supporting means.
Abstract:
A single box gabion is disclosed. The gabion comprises interconnected side walls. Each side wall comprises at least one substantially closed side wall element panel that prevents a gabion fill material from falling through the side wall without the aid of a gabion lining material. The single box gabion can be coupled together to form a modular gabion structure to protect military or civilian installations from weapons assault or from elemental forces, such as flood waters, lava flows, avalanches, soil instability, slope erosion and the like.
Abstract:
A transportable wave suppressor and sediment collection (WSSC) system positionable in deep water along a coastline of a body of water, having a plurality of sections, each section further including a base portion having an upper floor portion, a forward wall, rear wall and two sidewalls and an open bottom end portion for being positioned on a floor of the body of water; at least a pair of raised elongated members positioned on the upper surface of the upper floor of the base; an upper portion to be secured to the base portion, the upper section having a angulated front wall to receive the flow of water through a plurality of flow pipes as the water engages each section; at least a pair of elongated openings in the upper portion for receiving the raised elongated members positioned on the upper surface of the upper wall of the base to define a means for securing the base to the upper portion. There is further provided a one way valving element positioned on the rear end of each flow pipe, for allowing water containing sediments to exit the pipe at the rear wall, but preventing the water and sediments from returning through the flow pipe; and a spacer portion to be positioned intermediate the base portion and upper portion, the spacer portion including a plurality of flow pipes to allow water carrying sediment to the rear of the section.
