A traffic barrier and soundwall system is disclosed having wide-flanged [or h-posts] vertical posts oriented with a flange facing a roadway. Traffic barriers are located between them. The barriers have recesses at the intersection of their backs and ends. Sound panels are stacked on top of the traffic barriers. A crash panel is located between the vertical posts, above one or more sound panels. The crash panels have recesses at the intersection of their backs and ends. Additional sound panels are stacked above the crash panels. An angle bracket is located in the recess. U-shaped connectors connect the recesses of adjacent traffic barriers together around a post. U-shaped connectors connect the recesses of adjacent crash panels together around a post, and above the traffic barriers and sound panels to achieve a MASH TL-4 crash test rating.

Embodiments relate to a plastic wall panel, comprising a hollow body having external walls and defining an internal cavity. The external walls include: a first major side wall, a second major side wall opposite the first major side wall, a minor top wall, a minor bottom wall, a first minor end wall and a second minor end wall opposite the first minor end wall. The minor top wall and the minor bottom wall each define mating structure to mate and align with another adjacent panel so that multiple panels can be tiled together to form at least part of a sound attenuation barrier. The hollow body defines a passage extending between the first and second major side walls and through the first and second minor end walls to receive a reinforcing beam.

An inspection device includes: an obtainer that obtains at least one captured image of a plurality of sound insulation plates; a deriver that derives a displacement of each of the plurality of sound insulation plates in the image; and an extractor that, based on the displacements of the plurality of sound insulation plates, extracts, from the plurality of sound insulation plates, a sound insulation plate of interest that moves differently from another sound insulation plate included in the plurality of sound insulation plates.

A sound barrier includes panels comprising a polymeric material and reinforcing inserts encased within the polymeric material; and a frame comprising posts positioned in spaced, parallel relationship and extending vertically upward, and defining inwardly-facing slots for receiving the panels. The panels are mounted lengthwise with ends within the slots and adjacent panels engage each other by tongues and grooves of lateral surfaces. Methods of making the sound barrier are provided.

A noise barrier system and method for quickly and modularly installing or erecting a temporary sound interruption wall. The system can include one or more panels each, a leveling bracket adjustably mountable to a support member, a clamping bracket for mounting a panel to a support member, a double clamping bracket for clamping a pair of panels together and mounting them to a support member, and a panel clamp for clamping a pair of panels together. The leveling bracket can include a support wall to support portions of adjacent panels, and an arm for removably securing to a flange of the support member. The panel clamp, the clamping bracket and the double clamping bracket can each include open channel configuration configured to receive a single portion of a panel or portions of pair panels, and a slidably adjustable clip for securing the portion of the panels therein.

A fence panel system includes a plurality of fence panels positioned in a line, each of the fence panels coupled together in series by a plurality of rail members that extend horizontally between a plurality of fence posts, where each of the fence panels having a first side edge and a second side edge opposite the first side edge with each of the side edges configured to receive a side edge of a second fence panel to form a vertical connection, and where each of the fence panels includes a plurality of mesas traversing from the first side edge to the second side edge. The fence panel system can further include a plurality of fasteners to connect the plurality of fence panels to the plurality of rail members.

Disclosed is an impact resistant traffic noise barrier system. The system includes a traffic barrier that is designed to be placed adjacent a roadway and next to a flow of traffic. The design and weight of the traffic barrier permit it to withstand a variety of vehicle impacts. As part of the system, a sound wall is installed along the top of the traffic barrier. The sound wall includes a series of beams that are secured to the traffic barrier via anchor plates. Acoustic panels are secured between adjacent beams. An anchor cable extends from an anchor post, to a first post, and along a number of intermediate posts. The anchor cable is thus suspended above the traffic barrier with the anchor cable being connected to the beams. As such, the anchor cable suspends the beams in the event they become separated from the traffic barrier.

A noise abating wall including piers with integral column members, columns each including two laterally extending wing walls, and a spandrel panel. The piers are secured in spaced ground holes with column members extending vertically from the pier securing the columns in a vertical orientation with the wing wall outer sides having a selected spacing from one wing wall of an adjacent column. The spandrel panels are wider than the selected spacing of wing walls of adjacent columns whereby the spandrel panel sides overlap the sides of adjacent wing walls. First connectors on the spandrel panel front face adjacent both of the panel opposite sides and second connectors on the wing wall rear faces adjacent the wing wall outer sides connect together to secure the overlapping walls and spandrel panels in substantially face to face contact.

The present invention corresponds to a device for deflecting and decelerating a flow comprising a deflecting surface, a support structure connected behind the deflecting surface and a vortex generator connected on the deflecting surface, where the vortex generator generates two turbulent flow zones, a first low pressure zone below the vortex generator and a second high pressure zone above the vortex generator, and where the deflecting surface is concave in the direction of the incident flow, and the vortex generator is on the concave part.

The sound absorbing board includes a body and multiple sound absorbing elements. The body has a first side surface and a second side surface. The multiple sound absorbing elements are formed on the body at spaced intervals, and each one of the multiple sound absorbing elements has a protrusion, a groove, and two sound absorbing openings. The protrusion is formed on the first side surface of the body. The groove is formed on the second side surface of the body and has multiple concave portions and at least one convex portion. The multiple concave portions are formed on a bottom surface of the groove. The at least one convex portion is formed on the bottom surface of the groove, and is formed between two adjacent ones of the multiple concave portions. The two sound absorbing openings are formed on the two opposite side surfaces of the protrusion, respectively.
