摘要:
An artificial reef comprises at least one bag which is generally configured to define at least a portion of a reef and which is at least partially fillable with air. An anchor is attached to the bag for maintaining the bag at a desired location substantially underwater. A plurality of such bags may be attached to one another and configured so as to define a reef which enhances the suitability of waves for surfing or which mitigates beach erosion.

The present invention provides an apparatus and system for dissipating water wave energy and for shoreline control including a module with a generally hollow body, a pair of opposed flanges attached to adjacent corners of the body, a pair of axially aligned mounting apertures in the flanges for connecting the body to similar bodies for forming a wave energy dissipation system, and a recess disposed between the flanges having a surface characterized by a plurality of boundary layer interrupting projections substantially disrupting any laminar flow of water past the surface and creating turbulent flow.

The present invention relates to a wave dissipating concrete block for covering a an inclined surface facing seaside on a breakwater for the purpose of dissipating waves securely and effectively. The concrete block of the present invention includes a cylindrical body, tapered lump legs projecting from the cylindrical body and branch legs cylindrically projected through a circular base disposed on the cylindrical body and having projections disposed thereon parallel to the cylindrical body.

A method for making a breakwater includes the steps of making cubic blocks each with interlocking grooves and ribs respectively formed on opposite corners of the cubic block; progressively interlocking the cubic blocks from shallow water to deep water by sliding the ribs in the corresponding grooves; flushing the top faces of the interlocked cubic blocks; and securing the engaged cubic blocks. The cubic blocks are placed in position from the land or the previously assembled breakwater, such that no barge is required and thus no water or weather condition needs to be taken into account
摘要:
A unidirectional geotextile fabric for use in reinforcement of earthen retaining walls, embankments, slopes and related structures. The fabric is an open grid of high modulus of elasticity strands extending in the weft direction and strands of comparatively lower modulus of elasticity material extending in the warp direction. The fabric is preferably coated with a curable resinous material of sufficient thickness to protect the glass strands from breaking as the fabric is rolled onto cores and unrolled at the job site. When laying the fabric, a roll of the fabric is placed at one end of the face of the earthen structure being constructed and simply unrolled in a direction generally parallel to the structure's face. Because the high modulus strands of the fabric are the weft strands they extend and inhibit soil movement in a direction substantially perpendicular to the face of the structure.
摘要:
A shore protective barrier system for protecting an existing seawall in the face of heavy storms including a plurality of used automotive tires aligned upright in a row substantially side-by-side with one another, filled with concrete to form a single integrated unit sunk horizontally into the ground as a break wall.
摘要:
A method of shore protection is provided which includes determining a required direction of travel of incoming waves to a shore or shore portion to protect the shore and locating at least one elongate reef (1) on the sea bed (2). The reef (1) is oriented at a pre-selected angle relative to an average or mode direction of travel of incoming waves (W) and having pre-selected dimensions selected to modify the direction of travel of incoming waves to the required direction after passing over the reef (1).

An artificial root system for gabions to control soil erosion has an anchor which has a nose cone threadable onto a threaded rod and deployable stainless steel blades. On deployment of one or more anchors on each of a series of rods, connectors are attached to the rods. These connectors have four couplers to receive the ends of threaded rods or bars, and a central coupler to receive one (passing through) or two (meeting) threaded rods or bars. Threaded cross bars or rods are attached to the connectors to form a framework to support geotextiles attached to the cross bars or rods to form a gabion, or gabion array. The gabions are then filled with suitable material, to repair, or replace eroded shoreline, river frontage, lake frontage, etc.

An engineered wood structure is shown that can be placed in an aquatic or other environment. It is particularly useful in environmental enhancement efforts as a resting place for various avian and aquatic species. The structure is preferably made from small logs. A number of logs are placed side-by-side to form a deck surface. A single log is spaced apart from and generally centered below the deck logs. A pair of spaced apart struts depend from the lower surface of each deck log and are connected into the keel log to form a unitary structure.
