Abstract:
A structural panel for forming sea walls, barrier walls and the like, fabricated of synthetic resin material for driving into the earth and for resisting deterioration from sand abrasion, water movement and other severe environmental conditions, comprising:said panel being elongated and of constant size and shape along its length and characterized by having been extruded length wise;said panel including in cross section:first and second opposed side sections disposed in parallel planes and displaced longitudinally from each other and each said side section including an inner surface facing the plane of the other side section and an outer surface facing away from the plane of the other side section and a distal edge and a proximal edge, and a central web section having opposed parallel edge portions joined to said proximal edges of said side sections;said central web section and said first and second opposed side sections forming obtuse angles at said inner surfaces;the distal edge of said first side sections being formed in a laterally protruding male locking element and the distal edge of said second side sections being formed in a female locking element sized and shaped to substantially surround and lock with said male locking element so that adjacent ones of the structural panels can be locked together at their distal edges to form a wall; anda strengthening rib integrally formed on said first side section, said strengthening rib having a length and a width, with the length of said rib extending at a right angle from the inner surface of said first side section at a position adjacent said laterally protruding male locking element and forming with said laterally protruding male locking element a recess for receiving a portion of said female locking element.
